vendor bsp...

This is just a set of scripts to rebuild a known working kernel for ARM devices.

Script Bugs: "[email protected]"

Note, for older git tag's please use: https://github.com/RobertCNelson/yakbuild

Dependencies: GCC Cross ToolChain

https://mirrors.edge.kernel.org/pub/tools/crosstool/

Dependencies: Linux Kernel Source

This git repo contains just scripts/patches to build a specific kernel for some ARM devices. The kernel source will be downloaded when you run any of the build scripts.

By default this script will clone the linux-stable tree: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git to: ${DIR}/ignore/linux-src:

If you've already cloned torvalds tree and would like to save some hard drive space, just modify the LINUX_GIT variable in system.sh to point to your current git clone directory.

Build Kernel Image:

./build_kernel.sh

Optional: Build Debian Package:

./build_deb.sh

Development/Hacking:

first run (to setup baseline tree):

./build_kernel.sh

then modify files under KERNEL directory then run (to rebuild with your changes):

./tools/rebuild.sh

ti-linux-kernel-dev's Issues

fatal: reference is not a tree: 4993d845b9af8a51255aa2978e25715f0207162e

While trying to build ti-linux-xenomai-4.4.y with build_kernel.sh, I get error

fatal: reference is not a tree: 4993d845b9af8a51255aa2978e25715f0207162e

I fixed this as follows:
first let it fail, then do this:

cd ignore/xenomai
git remote add xeno git://git.xenomai.org/xenomai-3.git
git fetch xeno
git checkout 4993d845b9af8a51255aa2978e25715f0207162e

then run build_kernel.sh again

Build specific kernel version

Hi, I am trying to build a specific kernel version (e.g. 4.4.9). Somehow, I only manage to build the version at the HEAD of the linux-stable repo (4.4.19 now). Is it possible to do that ?

Thanks and best.

P9.19-P9.20.patch and PRU vs HW UART

In reference to af15b78 which you helpfully pointed out when I was asking on dtb-rebuilder, I am having a bit of trouble.

To achieve flow control on UART1, you suggested I simply claim them:

config-pin P9_19 uart
config-pin P9_20 uart

However, I got the same old response when I attempt this

$ config-pin P9_19 uart
Invalid mode: uart

Upon closer inspection of your patch, I realized that the most relevant added pinctrl-name is in fact pru_uart. This is new to me but it looks like it's software UART via the PRU peripheral. That would be fine for my application, but there is no device file yet (/dev/ttySU0) for this kind of UART. I'm going to see how to make that happen, but I am wondering, was hardware UART intentionall omitted in this patch?

pinmux file not found , pin has no cape

Hello.
I have encountered a problem when configuring a pin. I want to use u-boot overlays.
I need to configure pins to use eQEP. Running following command:

config-pin P8.33 qep

results in:

P8_33 pinmux file not found!
Pin has no cape: P8_33

Here is the output of sudo /opt/scripts/tools/version.sh:

Network issue

Goodmorning to all,
I've just installed the kernel version:
Linux arm 4.14.108-ti-xenomai-r120 #1 SMP PREEMPT Thu Oct 10 09:31:35 CEST 2019 armv7l GNU/Linux
and root file system:
debian-9.8-minimal-armhf-2019-02-16
following the steps explained here:
https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black

I've got some difficulties implementing an Ethercat master using SOEM repository on my beaglebone black. Reason why I've opened an issue here:
OpenEtherCATsociety/SOEM#344
For information if I install the same repository in my PC Ubuntu 16.04, it works like a charm.

They suggest possible problems:
There has been a bug in the network stack last year that prevented outputting the correct frames. It can also be there are some firewall rules active that prevent frames returning to SOEM.

Do you have any information/ideas about that?
Thank you in advanced.

rcu_preempt detected stalls on CPUs/tasks

I build 4.14.108-ti-xenomai-r143 and Ubuntu18.04 on Beaglebone AI. and i compiled IGH,when i start ethercat and scan slaves,it works well.but when i using the xenomai example in IGH .system will get stuck.i have no idea about it

How to generate patches ??

HI Robert,
I have a curious question. which script generate those patches ? manually ?
https://github.com/RobertCNelson/ti-linux-kernel-dev/tree/ti-linux-4.9.y/patches

kernel 4.4 can't boot on beaglebone ai

kernel 4.14-xenomai boot ok, 4.4 failed to boot.
can any modification to boot 4.4 kernel?
because of some reason, i want to use 4.4 kernel. why it can't boot?
Thanks very much and regards

Hi

I want to use the dmtimer library:

header file: /include/clocksource/timer-ti-dm.h
C FIle: /drivers/clocksource/timer-ti-dm.c

in a kernel modul: https://github.com/ddrown/pps-gmtimer/blob/ti_4_9_x/pps-gmtimer.c

(this is an old version of the module to use it now, i changed the header:
#include <plat/dmtimer.h> to: #include <clocksource/timer-ti-dm.h>)

the modul use a hw-timer for a pps device.

if im compiling the module i get the following compiler-warnings:

WARNING: "omap_dm_timer_get_fclk" [/pps-gmtimer/kernel/pps-gmtimer/pps-gmtimer.ko] undefined!

and if im trying to load the compiled module with:

sudo insmod pps-gmtimer.ko

i get the following errors:

In the thread: https://e2e.ti.com/support/processors/f/791/t/821652 the problem was solved by editing timer-ti-dm.c and adding the EXPORT_SYMBOL-macro to the missing functions.

But if i use this solution i have to manipulate and rebuild the kernel... and this not a user friendly way to use the dmtimer library.

So my question: Is there way to use the dmtimer library in an kernel modul without rebuilding the kernel? or Do i have to take another way to use the timers - which one?

can sgx_build_modules.sh be supported?

Hello,
In bb-kernel respository, there is sgx_build_modules.sh support.
I am wondering if ti linux kernel dev can also support sgx build.

Thanks,

Using rpmsg crashes the drive

As an example of using the rpmsg feature, this application (https://github.com/RoSchmi/Beaglebone-PRU-RPMsg-HelloWorld ) demonstrates what I'm seeing when I'm trying to use rpmsg.

Once I build main0.c for the pru, I copy am335x-pru0-fw into /lib/firmware, and start it with echo start >> /sys/class/remoteproc/remoteproc1/state I get the following error in dmesg (then the system becomes unstable until I reboot).

cpu freq scaling.

On the xenomai branch at least, you have CPU freq scaling disabled.
Will the BB default to max clock rate? Does this depend on U-boot?

tools/rebuild_deb.sh rebuilds the whole kernel

I noticed that, unlike tools/rebuild.sh, tools/rebuild_deb.sh invokes at one point make clean and consequently rebuilds the whole kernel, even if there were no or small changes.

This is because in the kernel source tree, in scripts/package/Makefile, the deb-pkg target invokes make clean, and you are using that target in (re)build_deb.sh. Maybe you could use the bindeb-pkg target, which does not build a source tarball, and does not clean the whole tree before compiling, but rather does an incremental build.

(I asked this on the linux-kbuild mailing list here and they gave me that advice).

BeagleBone Black Bluetooth can't be loaded

I searched everywhere and the only possible solution I can find that might work is just to recompile the kernel with the module, which I didn't have the time to try yet. But I'd like to make sure that is the case here.

beaglebone AI errors in kernel and no wlan0

Hello, I am running through the (BeagleBone AI) https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone-AI tutorial.
When I follow the tutorial I get errors in the kernel and also wlan0 doesn't seem to work at all.

Just hoping you might happen to know the reason or how I can fix this. I am relatively new to linux and this is my first attempt at embedded linux.

these are the errors I get in dmesg.

devices/system/cpu/cpufreq/ is empty on 4.19.73-ti-rt-r29

I'm using this repo to compile the kernel version mentioned in the title for a beaglebone green.

I suspect that the cpu frequency is set to a low value because my app is consuming a lot more cpu than before, when I was running 4.4.x-bone-rt.

The directory /sys/devices/system/cpu/cpufreq is empty so I don't know how to verify or set the cpu frequency.

Below are the relevant options from kernel defconfig.

Perhaps I am missing some kernel configs?

dmesg does not show any message regarding cpufreq.

Please help. How can I make sure my cpu is running at full freq?

xorg cause high cpu usage with kernel 4.14

I use the kernel 4.14 on beaglebone black and ai， both xorg cause high cpu usage. for example, i move the curse on the terminal, the terminal and xorg will cause high cpu usage showed in commant top.
when i use 4.9 or 3.8 kernel in beaglebone balck, it not.
anyone know why? how to fix or config to solve the problem?
thanks

CONFIG_ANDROID active for ti-linux-xenomai-4.4.y

Is this expected?

Can't find the output files ZImage and dtb

Hi,
I'm trying to build the kernel from this repository. After executing the build_kernel.sh the compilation get finished but the deploy folder is empty. Do I need to set a configuration during configuration of kernel?
Thanks.

no MDIO, no PHY, no Ethernet on BeagleBoneBlack with Kernel >5 (tested on 5.4 and 5.10)

Sorry if already there. Google could not really help me. Everything was out of date.
On my BeagleBoneBlack Board Rev. B6 with AM3358BZCZ100 the MDIO does not come up with kernel 5.4 and 5.10.

dmesg says following
mdio_bus 4a101000.mdio: MDIO device at address 0 is missing
phy "/ocp/interconnect@4a0000/segment@0/target-module@100000/ethernet@0/mdio@1000/ethernet-phy@0" not found on slave 0

I changed in /arch/arm/boot/dts/am335x-bone-common.dtsi under "ethphy0: ethernet-phy@0" reg = <0> to reg = <2>. After that everything was ok. I am not sure if I have fixed it correctly. Maybe it is better to overlay it in am335x-boneblack.dts because the am335x-bone-common.dtsi is included by several boards.

It took me a while to find it.

Again the correct section am335x-bone-common.dtsi
&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;
status = "okay";

ethphy0: ethernet-phy@0 {
	reg = <2>;
};

How to update to latest 4.19.y ?

I'm dealing with an issue in my application and would like to test it with the latest 4.19.y kernel (currently, 4.19.142).
Can you tell me how can I build a kernel based on the latest mainline 4.19.y and with the BeagleBone's specific patches?
The naife approach of replacing in version.sh KERNEL_TAG=${KERNEL_REL}.94 with KERNEL_TAG=${KERNEL_REL}.142 does not work, as it generates a lot of patches conflicts.

How to bring up-to-date a branch on this repo?

Hi there,
I am interested in reviving the ti-linux-xenomai-4.4.y branch (and possible other more recent Xenomai branches later on), bringing it up to date with the latest ti-linux-4.4.y (or whatever a suitable upstream branch is)?. Could you please explain what is the suggested workflow to do so? I looked at the scripts in repo_maintenance, but I could not make sense of those.
Thanks

Serial configuration in 4.14.49-ti-r54 kernel

Hello

I'm currently trying to use all the 10 uarts on my platform however the kernel configuration has only 6 available (ttyS0, ttyS1, ttyS2, ttyS3, ttyS4, ttyS5). I have tried doing the change manually in the lines

CONFIG_SERIAL_8250_NR_UARTS =6 --> CONFIG_SERIAL_8250_NR_UARTS=10
CONFIG_SERIAL_8250_RUNTIME_UARTS=6 --> CONFIG_SERIAL_8250_RUNTIME_UARTS=10

of my config-4.14.49-ti-r54.txt file but with no sucess. I saw your files and tried to do it as the README however I still have 6 ports instead of 10, what am I missing?

linux/version.h

I noticed that /usr/include/linux/version.h is not part of the linux-headers*.deb, so that /usr/include/linux/version.h always is the default one that came with the distro. Is this expected behaviour?

can the branch 4.14.108-ti-xenomai-r136 be used on beaglebone ai?

can this kernel be used on beaglebone ai?
thanks!

and when i git clone the code, always be asked for the username of gitlab.denx.de, why?

Beaglebone AI and I suspect all the BB don't work with etherCat

Hello,
I was unable to get the Simple Open EtherCAT Master software working on the BBAI with 4.14, 4.19 and 5.4. I brought this up with the guys in charge of the SOEM repository and they linked me to this potential issue.

https://patchwork.kernel.org/patch/10697191/

The CPSW ethernet hardware is padding the packets wrong, which is causing issue with some industrial automation protocols.
Such as my experience with a EtherCAT slave not responding to packets sent form the BBAI.

I was able to fix this by changing min packet size to 60 in cpsw.c when rebuilding the kernel

I hope this is the correct location to post this.

Cheers,

Chris

#EDIT
on further analysis looks like TI is aware of this and it needs to stay as is to work with VLAN properly.
I'll close this issue and just implement the work around for my use case.

CONFIG_CPU_FREQ should be disabled for Xenomai

CONFIG_CPU_FREQ should be disabled for Xenomai, as reported, e.g.: here
... but it is enabled in defconfig in the xenomai-4.4 branch

Note that when you exit menuconfig you get a warning reminding you that CONFIG_CPU_FREQ should be disabled.

omapdss error: HDMI I2C timeout reading EDID

Hello, as the title shows, when I use ./build_kernel.sh to compile the kernel for BeagleBoard X15,
and make a SD-Card system following the BB-X15 Getting Started

Then after booting, I got:
omapdss error: HDMI I2C timeout reading EDID
from serial output.

So I can access the board only by SSH/Serial/.. remotely.

How can I fix this problem?

Information:

• Kernel: 4.9.77-ti-r92
• Hardware: Beagleboard X15 RevC
• HDMI: Dell

Kernel 4.4, ethernet get wrong IP

Hi,
I tried the image of image built on May 2017, Debian and Ubuntu, on my BeagleBone Black revC. There is problem with networking:

• Appear 2 USB network: usb0 and usb1
• eth0 gets wrong IP from dhcp

Output of ip addr:

I expect eth0 to be 192.168.1.x.

unexpected IRQ trap at vector 91

This is on 4.4.87-ti-xenomai-r121 (773261a).
Configured with: https://pastebin.com/nEk12b3y

Procedure:

cd /sys/class/gpio
echo 115 > export
cd gpio115
echo both > edge

then connect P9_27 to ground or 3.3V alternatively. You will get the following the first time it changes state:
