Beagleboardxm and spidev

Hi @RobertCNelson,
which is the clock frequency for Mcspi4?
I’ve connected an Attiny841 as slave: it receives the command from bbxm tx buffer but sometimes it sends unexpected values inside the rx buffer.
I’m using the spi_test.c as testing code.
Kernel 5.19.

It is what ever you set it it to via the spi-max-frequency value:

spi-max-frequency = <48000000>;

5.19? maybe in 2 years…

Regards,
