Clone Devo8 was created by josh147

I'm trying to use this board:
STM32 board

to clone the Devo8.
Usually, one the code compiled, Devo has its own bootloader to load the image.
If I use this board, and it comes with STM USB bootloader, what should be changed? Linker script or something else?

I can't answer your question, but just wanted to say, NICE! If you manage to get that working, you could turn a 7e into an 8s!!

Good luck with your project... cheers

I have that board. It does not have enough RAM or ROM to support the Devo8 build. I'm not sure theLCD driver we're using is compatible either. It is also a pain to work with because many of the I/O are dedicated.

I'm not saying it is impossible, but it is a serious amount of work to do.

Turn out got this board:
www.powermcu.com/product-8.html

The same CPU used in DEVO8. The LCD controller is not the same but close enough. No SPI flash on this board, but a SD card slot. I'm going to change the code to use SD card instead of SPI flash.

The Keil MDK can't compile the devo8 code due to coding style. Trying to integrate YAGARTO to Keil uVision MDK.

Just a question, I can't find startup.s code in the source code. Where does it locate?

libopencm3 provides the startup code needed. Just linking itmakes everything work. Well, that and the linker file.
I would probably recommend using Eclipse rather than Keil, but if you get it working, let us know.
