[GitHub] [incubator-nuttx] patacongo opened a new pull request #1056: boards/arm/stm32h7/stm32h747i-disco: bring support for SD card and FAT FS
patacongo opened a new pull request #1056:
URL: https://github.com/apache/incubator-nuttx/pull/1056
boards/arm/stm32h7/stm32h747i-disco: bring support for SDMMC
arch/arm/src/stm32h7/stm32_sdmmc: check IDMA buffer address
For SDMMC1, IDMA cannot access SRAM123 or SRAM4. Refer to ST AN5200 for
details. This patch makes stm32_dmapreflight check the buffer address and
return an error when the buffer is located in a invalid address space.
This does not fix the hardware limitation but at least makes it visible.
boards/arm/stm32h7/stm32h747i-disco: bring FAT DMA allocator
Buffers are allocated in the main ram, which is suitable for use with the
underlying STM32H7 SDMMC1 core in IDMA mode.
Files are copied from stm32f7/nucleo-144.
