Firmware Changes to fix software shutdown timing and other improvements #13

Closed hoopsurfer closed 4 years ago

hoopsurfer commented 6 years ago

Requested firmware for STM8S MCU to address firmware issues from Embest - no reponse to date.

Ideas: 1) Make software shutdown (OS initiated) as fast has button push - need to signal MCU to do the same as button press initiated shutdown 2) Support "press press" reboot to allow button initiated reboot

Note MCU is STM8S005CK part, 8-bit controller with 32Kb flash plus 128 bytes EEPROM, 2Kb RAM onboard pins are labeled for programming MCU.

I have purchased a STM8S development board to start reverse engineering the firmware, if anyone has STM8 experience or wants to help let me know!

I've been able to convince the Support team at Embest Technologies to provide sources rather than have me continue decompiling the code. I've stopped that work now that I have the sources and have them building now.

Do you have any progress? I guess you are not allowed to share the source code of the factory firmware, but I would be glad to help you.

While I have the firmware rewritten, I've decided not to publish/support it because RP4 is taking such a different direction, you can find the source code for the firmware in this repo:

Actually, I don't have RPi3 and PiDesktop anymore, I also went for RPi4. Anyway, thank you for the support so far. Best wishes!
