porting to STM32
Locked
|
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? Justin _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

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.

Thanks very much, that sounds quite simple. Justin _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

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 On Mon, Nov 18, 2013 at 9:22 PM, Justin Cormack <[hidden email]> wrote:

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... > Best, _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |
