ChibiOS Free Embedded RTOS

I have finally resolved all my issues with SDMMCv2. This is a summary of what I found, the patch we are using can be found at https://github.com/ArduPilot/ChibiOS.svn/pull/2/commits/64da8ae744c1bc901124a0060971fbb6b579e67a new link: https://github.com/ArduPilot/ChibiOS.svn/pull/2/commits/acb1d47de12...

STM32_SDMMC_MAXCLK is not set in hal_lld_type1.h or hal_lld_type2.h and so defaults to 50Mhz which is way too low.

I suspect the values defined in hal_lld_type3.h are applicable to type1 and type2 as well

Support for STM32H730 chip

I would put in RAM the RT kernel, the OSAL and your ISRs, the rest is to be evaluated case by case, probably some specific drivers.

Thanks - is there a way of easily identifying these for the linker script?

So I'm back on this. I bought a DevEBox https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M which was a much simpler way of getting an external flash development board, and thanks to some great work by a colleague we have external flash working and the autopilot running in external flash. There is obvi...

Hi, Update, I modified things to be compatible with "-Wcast-align=strict". I think you are compiling the code using the C++ compiler (correct?), this is why you are seeing the warnings. I fixed all casts to (thread_t *), post here if you find more instances of the problem. Cleaning things...

Moving in bug reports.

Any idea how to fix? I can just turn off the warning but don't know if that is safe or not.

Hi, I would rate this thing "hard". You need to check carefully the sequences sent to the memory, the code enforcing a reset state (hard to get right), the switch to the full N-wires mode, SDR and DDR modes, number of dummy cycles, and lots of other details. Those chips, except for a basi...
