Hi folks, I'm in the process of tidying up my STM32 SPI driver code for more general release. While it all works fine for on-chip memory (my particular use case), the DMA does not support access to external memory (generic STM3210E-EVAL). This means that I'll need to add optional support for DMA bounce buffering via the on-chip SRAM.
I'm sure that this is a problem which must have been addressed on other platforms. Is there a convention for setting up such a DMA-specific section in the memory layout files - and are there any existing examples you can point me to? Chris.
