porting to STM32

How different are the STM32 eval boards? I see there is a port for
STM32F4DISCOVERY, if I were to pick another board with the same CPU
but different peripherals/memory size would porting just be a matter
of config for the other peripherals or are there annoying random
differences? Anyone got an estimate of the amount of work?

Hi Justin,

I have ported eLua to a board designed at Freie Universität Berlin. It
features an STM32F415RG processor, a JTAG interface, which in connection
with [1] works like the Mini USB port on the DISCOVERY board, and a
Micro USB port that again works like the Micro USB port of the DISCOVERY
board. No configuration should be needed for these.

Apart from the peripherals, porting was quite easy. You simply
copy/include the file boards/known/stm32f4discovery.lua and do some
minor adjustments. The header file for the 415RG processor was the same
as for the 407VG.

Best,

Richard

Thanks very much, that sounds quite simple.

Re: porting to STM32

Yes, it would ideally be as simple as ts Richard described. More complex scenarios involve different CPUs, it all depends on your target board.

Best,
Bogdan

Well my aim was to pick one as close as possible to what's supported but with slightly different IO built in, and the memory size I want...
