Finally got around to connecting my #olimex #ice40 development board to power again, and getting a bit stream programmed onto it.
(I really haven't played enough with it)
"Back in the day" I'm sure I used a raspberry pi for the programming.
This time I tried using a dirt cheap #ch341a for the programming, its a bit on the slow side, especially when programming all 2MB of SPI flash.
Probably should limit the number of bytes to be programmed and/or switch to one of my #ch347 boards
Finally!
Daring again to flash #heads #coreboot from #nitrokey onto my good old #thinkpad t430.
The documentation is pretty horrible, as a beginner it was really hard to find info on how the hell to assemble a #CH341a programmer?
Got it working, see on the picture.
Then running #flashrom (as root, couldnt find the udev rules to allow it rootless) to detect the chips, backup and verify the stock ROM, and write heads onto them!
Что нового в IMSProg?
Пару месяцев назад я писал историю создания программатора микросхем CH341a для Linux систем. Благодаря вашим отзывам и комментариям программа изменилась, надеюсь в лучшую сторону.
CH341A tool
This is a Windows tool adding extra functionality to popular EEPROM/FLASH programmer based on #CH341A USB to I2C/SPI/UART converter - using it as a general purpose interface.

why do i keep getting this error:
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.
I swear I've connected everything properly and even supplied the router with power, as well as supplying the #CH341A programmer with ample voltage, and yet even after switching connectors, it won't work with me.
Either I need a reboot, a universal programmer, a better probe, or I need to read the manual more.
this already reminds me of my first days with #voidlinux.

For some older #Toshiba laptop's #mainboard, a Satellite A210-15Y model, I needed a bit more power than the #CH341A could deliver to read the #firmware from the flash chip. This is as hacky and safe as it looks, but it works. :)
