@davids5 I think that the default slew rate is for 50Mhz. This is not excessive for SPI. This seems like a hardware design problem (lines termination etc), and I don't thing we should make a change in NuttX for this. It make break other user's code. Maybe we should add a new configuration in Kconfig, so the user can select the slew rate for every SPI, while keeping the default at 50Hz. (As a side note, ringing usually does not have enough energy to cause latch-ups in other chips, although max. VIH is violated. But of course you know better, as you tested the actual hardware...) @raiden00pl Maybe open a new issue for the STM32H7's? To gather there all information, and maybe I will find some time after vacation to actually implement this. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
