How to port SPI-SLAVE Driver to A72 core

What is meant by "porting" and  its use case? Are you referring to RTOS or QNX here?

I'm very sorry if my question confused you. What I'm wondering is how can I make SPI_SLAVE work like other TEST APPs in QNX.

1. When I run the command you wrote, the following error occurs.
This error is confirmed because there is no build rule for MCSPI_Baremetal_Slave_TestApp in the makefile.

now i made mcspi_baremetal_slave_testapp_mcu2_1_release.xer5f  file

I am uploading the file to mcu2-1. I copied the file to sdcard and uploaded it with the following contents while booting u-boot.
The method is
1. rproc init
2. load mmc 1:2 0x90000000 /lib/firmware/mcspi_baremetal_slave_testapp_mcu2_1_release.xer5f
3. rproc load 3 0x90000000 0x${filesize}
During item 3, it failed as follows and the log is as follows.

k3_r5f_rproc r5f@5d00000: Invalid seq: Enable primary core before loading secondary core
Load Remote Processor 3 with data@addr=0x90000000 716940 bytes: Failed!

Based on the above, I think I need to enable the primary core first. How should I proceed?

Hello,

Yes you need to load primary core as well before secondary.
