karosium / smbusb Goto Github PK

Hi, can we use this solution to reset / reprogram a laptop battery?
It' s not clear to me if this is only for reading the data of the battery or being able to write to the chip too.

smbusb_scan -a only seems to work until it finds my controller (bq8030), after that it always comes back with ERROR -9.
First scan:

Every time I plug in the FX2 it will work exactly once. I tested it on my laptop running Manjaro and on a Raspberry Pi 2.

1. I'm having trouble flashing the program. Normally I would blame my hardware for this but I played around with two batteries and both showed the same issue. One is now bricked but the other works so I can still try things out ;)

2. In your blog you mentioned that Error -11 means LIBUSB_ERROR_NO_MEM.
   I tried to understand why that would happen and came across the writeProgramBlock function where you return status-2. If I understood that correctly SMBWriteBlock returns the size written successfully or alternatively a negative number in case of an error. If that is correct you should return (status > 0 ? status-2 : status); in writeProgramBlock and the same for writeEepromBlock. I'll send you a PR if you confirm this.

writing the eeprom works like a charm:

can this be used with ch341a chip i2c mode to read smbus on battery? thx

Hi,

Libraries` have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:

• add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
  during execution
• add LIBDIR to the 'LD_RUN_PATH' environment variable
  during linking
• use the '-Wl,-rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to '/etc/ld.so.conf'
  See any operating system documentation about shared libraries for
  more information, such as the ld(1) and ld.so(8) manual pages.

And then I'm trying to run smbusb_scan -a and getting:

My device is connected though, do you know what might be the problem?

Looks like updating the fx2lib submodule lets the firmware build with the latest sdcc but would break compatibility with older versions which I assume a lot of people still have.

Quick fix if the firmware doesn't build with your SDCC (probably versions 3.8 and up):

cd fx2lib
git checkout master

I am using degilent jtag usb cable,can it be supportted?

Hi.
I just tried to clone an follow instructions.
After:

./init.sh
./configure (options: --disable-firmware, --disable-tools)
make
make install

I tried to run:
smbusb_scan -a
and I got this error:

smbusb_scan: error while loading shared libraries: libsmbusb.so.1: cannot open shared object file: No such file or directory

This project seems really useful. I am trying to use it to communicate with a smart battery / charger combination

When I run watch -n 1 smbusb_sbsreport, it usually works a few times, but then starts failing consistently with all error values, like below

When I power cycle the FX2LP, then I start getting real values again. I unfortunately don't understand the code well enough to understand why this might be happening. Any ideas?

There are two major smbus modules for Python, already:

• smbus
• smbus2

But these are using Linux kernel i2c modules, so are not multi-platform, and I don't think there's a way to use them over USB.

I think it might be useful to create Python bindings for smbusb as well, preferably keeping the interface used by existing modules.

(Just wanted to start a discussion on that, feel free to comment.)

Build is failing with Arch Linux because of the newer version of SDCC (3.6.0-4)

Thanks for any help.

First of all: thank you so much for all that useful information! :)

I was wondering if somebody has already adapted the tools to work with /dev/i2c on linux?
This is probably not a good idea, but messing with batteries is not a good idea in the first place i guess?

And apart from that, somewhere in a forum i saw a post suggesting that one could use a modified video cable to talk to i2c devices, and i was able to replicate some of the functionality of smbusb with i2c-tools and the vga port, including entering boot rom mode, checking the boot rom version (also 3.1 on my chip) and reading blocks with i2ctransfer.
But before i try to write and brick the chip i thought it would be a good moment to ask some dumb questions...
would it e.g. be possible to just edit/rewrite single blocks? (or actually 2 blocks if i understood that right?)
or in other words, is it necessary to dump, erase and rewrite everything?
the erase part is necessary as far as i understood?
I tried to understand the code of the flashing process without too much success so far.
if i get that right, a word write of 0x83DE to 0x12 would erase everything?
and then it does block writes?
and then, what does the
SMBSendByte(0x16,CMD_EXECUTE_FLASH);
do? is that just to exit the boot rom mode?
sorry for all the stupid questions...

It looks like Eeprom verifying after writing to DF is bypassed.
Here in the code effective comparison length is Zero.

54 #define EEPROM_BLOCKSZ 0x20
...
58 #define EEPROM_RESERVED_BYTES 32

...
...
...

423 if (memcmp(block,block2,EEPROM_BLOCKSZ-EEPROM_RESERVED_BYTES) == 0) {
424 fprintf(stderr,".");
425 } else {
426 printf("Block verify fail. Block #%d\n",i);
427 exit(0);
428 }

Following correction to code should enable it.

...
416 for (i=0;i<EEPROM_BLOCK_COUNT - (EEPROM_RESERVED_BYTES/EEPROM_BLOCKSZ);i++) { ... }
...

423 if (memcmp(block,block2,EEPROM_BLOCKSZ) == 0) {
...
```C

If it's Ok will revert with pull request.

Add precompiled files for cp2112. so i can directly use with my cp2112.

thanks

Since SDCC 4.2.3, interrupt numbers need to be parenthesized. The attached patch fixes the firmware so it compiles with current SDCC.

Hi
I am constantly getting following error :
Error Opening SMBusb: libusb error -11
both for smbusb_sbsreport and smbusb_scan

Device is enumerated as
Bus 001 Device 006: ID 04b4:8613 Cypress Semiconductor Corp. CY7C68013 EZ-USB FX2 USB 2.0 Development Kit

Any assistance is appreciated

Hi.
Little help please.

I was trying to compile the tarbal but I get the following error that some point:

$ make
Making all in firmware
make[1]: Entering directory '/home/psysc0rpi0n/Downloads/smbusb-1.0.1/firmware'
Makefile:6: ../fx2lib/lib/fx2.mk: No such file or directory
make[1]: *** No rule to make target '../fx2lib/lib/fx2.mk'.  Stop.
make[1]: Leaving directory '/home/psysc0rpi0n/Downloads/smbusb-1.0.1/firmware'
make: *** [Makefile:386: all-recursive] Error 1

What am I missing? I have pkg-config and libusb installed.

$ sudo apt install pkg-config
pkg-config is already the newest version (0.29-6).

$ sudo apt install libusb-1.0-0-dev
libusb-1.0-0-dev is already the newest version (2:1.0.22-2).

$ sudo apt install libusb-1.0-0
libusb-1.0-0 is already the newest version (2:1.0.22-2).

CP2112 maybe?

Hi, since the build depends on xxd, I searched which package provides it, finding dev-util/xxdi and app-editors/vim-core (on Gentoo). Since there is only one place where xxd is used, and it's invoked as "xxd -i", it would be useful to add xxdi as an alternative to xxd, since it's much smaller (xxdi is 8KiB, vim-core 14MiB).
