I have MCU which is connected to SPI interface in the jetson, jetson will act as a master and MCU will act as a slave.

If i send command from MCU to Jetson, for example i am sending 0x03 and in jetson i am receiving it as 0x10, not sure this is because for SPI speed, my MCU firmware operates with 500kHz, i tried configuring the speed in jetson, using spi dev test tool, but still my clk frequency is 3.1Mhz which is min rate of parent clk, i tried changing the parent clk but still it is taking min rate of the selected parent clk. I am using SPI1.

HI there @stamil3006, welcome to the NVIDIA developer forums.

We have dedicated Jetson categories for all the different models, if you share which one you are using, I might be able to direct you to the correct one.

Thanks!
