Firmware? #5

Closed dimecho closed 5 years ago

dimecho commented 5 years ago

A bit confused about which firmware to use? Tried "slcan CANable firmware" but it builds for STM32F042x6. DFU flashes it but CAN not working. Is there a .hex or .bin for this hardware?

Have a look at https://github.com/nexulm/candleLight_fw/blob/fa7a75c04ef5fbaab253ac6e34735fadccb97d17/Makefile#L63-L67, @nexulm seems to be using the hardware and made the required changes to get it working with candleLight. Would be great to get some feedback if you try it out :)

Thanks,

I changed 2 things for STM32F072xB

ASM_SRC = system/src/cmsis/startup_stm32f072xb.S

and

usb2can: $(MAKE) CHIP=STM32F072xB BOARD=usb2can bin

Compiled OK.

Bad news as soon as I pressed RST button magic smoke and chip burned - both red and blue LEDs stayed on. Unless I soldered something incorrectly the hardware is not 100%, did anyone actually build this? Why would STM32 burn by pressing RST?

Second try, works! I must have shorted something ...don't know, components are small. All works took a lot of research. Got it to work with special CandleAPI driver with cangaroo app https://github.com/normaldotcom/cangaroo/
