Hi Kiyung,
Please check this BuildSheet page for SDK 11.02: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/11_02_08_02/exports/docs/devices/AM62X/linux/Release_Specific_Build_Sheet.html. We support MCU_SPI in Linux in controller mode.

Ok, thanks Divyansh.

So, the A53 Linux application can just use the MCU_SPI the same way as the main domain SPI, there is basically no difference, correct?

 ls /dev/spi*
/dev/spidev1.0  /dev/spidev1.1  /dev/spidev1.2  /dev/spidev2.1

Hi Kiung,
We do not have any tested examples for this, but yes, it should work similarly.
