Hi
I am not getting tool chain file for pico-imx6 (at build-x11-pico/tmp/deploy/sdk) ie,
poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.7.sh

Instead fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-4.1.15-1.2.0.sh is available.

Bit bake commands

1. For yocto build
   DISPLAY=lvds7 MACHINE=pico-imx6 BASEBOARD=nymph source edm-setup-release.sh
   -b build-x11-pico -e x11
   bitbake fsl-image-qt5

2. For toolchain build
   bitbake meta-toolchain

Please tell me what is the issue. I am using ubuntu 16.04

Hi,

Hi
I am using your toolchain 4.1.15-1.2.0 for imx6.
while compiling gpsd (gps daemon) using this toolchain i am getting error :

Apparently the pico-imx7d board is not supported , any plan to implement the support for this?

Hello,

While the board is not connected to internet and rebooted it sometimes happens that the reboot freezes. In 99% of time it happens at:

[ Ok ] Stopped Update UTMP about System Boot/Shutdown.

Is there a fix for this issue?

Thank you,
Renegade

Hello Richard

Is a release done with Yocto 2.5 ?
We want to move to QT5.12 and Yocto 2.4 is linked to QT5.9

Thanks

Hi
Do you provide as how to integrate systemd for Pico Nymph.

I'm building an image for my pico-imx6ul. The result is an image running without the right device tree.

For example, the board can't load any wifi card.

This is my build configuration:

At the moment I use dd to flash the content of this archive:

    core-image-base-pico-imx6ul.sdcard.bz2

u-boot is using this device tree:

    imx6ul-pico-qca_pi.dts

But I want this one:

    imx6ul-pico_pi.dtb

Should I use a new Yocto version to correct this?

Hi
Please provide the password for virtual machine ubuntu 16.4.

Hi
I am getting below while building tn_imx_yocto-2.0-jethro_qt5_source_20161209.zip

insn-opinit.c: In function 'void init_all_optabs(target_optabs*)':
insn-opinit.c:764:1: internal compiler error: Segmentation fault
init_all_optabs (struct target_optabs *optabs)

I was able to build it earlier.

log.do_compile.24363.zip

I made a layer and some recipes to:

1. install correct WiFi drivers with the module bcmdhd;
2. boot my board with the correct dtb file imx6ul-pico_pi.dtb;

When I do:

modprobe bcmdhd

This is the output and this is correct:

I'm able to connect to the WiFi even if I've the error.

What's that error?

UPDATE
This last line seems to be a message from system that is printed in the debug serial console

Audio playback issue on PICO-PI-IMX8M-2G using the linux tn-imx_4.14.98_2.0.0_ga-wip kernel (prebuilt image fsl-image-qt5-validation-imx-pico-imx8mq).

Running some test commands I get the following output:

I will try to setup a build environment to build the latest, but this is using the latest prebuilt image available for download.

Is the new BSP sumo 2.5 is compatible with pico-imx6 ?
Thanks

hi,
I try to add optee for pico-pi-imx7 board in current yocto version.
I add below lines in local.conf
..
DISTRO_FEATURES_append=" optee"
IMAGE_INSTALL_append = " optee-client-imx optee-os-imx optee-test-imx"
..

but I can not pass bitbake fsl-image-qt5-validation-imx
but I used a old version( a few month ago , I cloned it), It passed bitbake, I can find xtest. only there is no device /dev/tee? after boot

so I want to try the updated yocto source code version, but the error happended! I can find optee-test-imx_git.bb optee-client-imx _git.bb optee-os-imx_git.bb there but why can not bitbake?
I want to know if pico-pi-imx7 board can support optee?

Hi I'm building sumo branch for the pico-imx8m, the compilation (besides some issues with building for the machine I had, for whatever reason) goes fine, but when I try to run the image on the board, everything is just fine up to the moment when weston should kick in.
I'm getting black screen with a cursor in top-left corner and nothing else.
Weston logs show nothing special the process is running, either started with systemd or manually.
I've build both for xwayland and wayland, and the result is the same.
Do you happen to know what is going on?
I had similar situation when I tried to port your rocko branch to sumo, by myself and I thought I messed something up, and put it on the hook until someone (that actually knows what he/she is/are doing ;) ) fix the stuff. But now I'm stuck ...

Hi,
During adding php to the image i met such error when executing php in device:
root@pico-imx6:~# php
php: relocation error: php: symbol mysql_server_init, version libmysqlclient_16 not defined in file libmysqlclient.so.18 with link time reference

I found solution: http://www.variscite.com/support-forum/viewtopic.php?t=372
Needed new version of binutils
https://github.com/varigit/meta-variscite-imx/blob/Krogoth-imx-4.1.15-var01/recipes-devtools/binutils/binutils-cross_2.26.bbappend
After these path everything works fine. Please consider update in your yocto distribution.
Best regards,

Hello,

The ethernet connection works fine with the imx8mq-pico-pi.dtb file, however once I switch the dtb to imx8mq-pico-pi-voicehat.dtb , the ethernet connection stops running. I'm not using wifi - didn't install it during the yocto image build procedure.

I assume there is an issue with the dtb. Is there a fix for this issue or any directions what should be checked/fixed to get ethernet running even with the voicehat dtb?

Thank you very much for any kind of help and have a nice day,
