Hi,
Thank you, I have confirmed that SPI seems to work with a serial eeprom
with the default slew rate.

Hi Sebastien,
I think it is a stale artifact from before the DMA was fleshed out.
We are using DMA on the H7 SPI in PX4. The only caveat is that the default
drive strength may be too high and we reduced it with the macro:
https://github.com/PX4/PX4-Autopilot/blob/main/boards/px4/fmu-v6x/nuttx-config/include/board.h#L417-L437
We had a sensor that worked when polled but when DMA was enabled. I could
see massive overshoot on the clock.
*Regards,*

Hi all,
SPI bus driver in STM32H7 requires the CONFIG_EXPERIMENTAL feature.
Is that still true as of today?
I will do some tests later but I would like to know if someone has
information about these peripherals, are these working or not, with
interrupt, dma etc?
Thanks for any info
Sebastien
