David,
I have BOARD_DMA_ALLOC_POOL_SIZE 5120 - as on other boards including
STM32F405RG based omnibus f4sd.
By the way f4sd doesn't set SPI2_DMA_BUFFER on SD card SPI2, but has
CONFIG_STM32_SPI2_DMA=y

Oleg,
You are most welcome,
Did you adjust the size of the board dma allocator?

Thanks for the enhanced feedback, David!
When I reduced the slew rate control from 50MHz to 2MHz it fixes issues
with a SD card when DMA is not enabled. But when DMA is enabled, MTD and SD
still are attached and mounted, but are empty, as I see on block reads -
px4 successfully reads mtd_params fi
