DMA with FMC device

[ranran]

Hello,

Is it correct to call

HAL_SRAM_Init()

for each external FMC memory ( So that each one has its own mdma handle )?

The story:

We have 3 memories: external nor, eternal sram, and fpga.

But we don't get the dma callback called after calling to

HAL_SRAM_Read_DMA()

with FPGA.

(FPGA read/write registers is OK, only burst does not work)

Can it be an issue with the device, or is it some wrong mdma handling ? I mean, should I expect a callback even if device is dead or in reset ?

Thanks,

ranran
