Part Number: PROCESSOR-SDK-J722S
Other Parts Discussed in Thread: ALP

Tool/software:

Hello,

When I tried this patches to apply it for J722S SoC with required modifications, I saw that the functions in the relevant main.c files in the patches were different for J722S.

Such as, this function doesn't exist in main.c files for J722S:

retVal = Mmu_map(DDR_C7X_1_LOCAL_HEAP_VADDR, DDR_C7X_1_LOCAL_HEAP_VADDR, DDR_C7X_1_LOCAL_HEAP_SIZE, &attrs, is_secure)

How to edit and apply patches to J722S for running vision apps with 2GB DDR?

Thank you.

    Hi Alp,

    J722s syscfg files to generate the init codes which will be there in the c7x_1/generated/

    You have to change the mmu mapping inside $(psdkra)/vision_apps/platform/j722s/rtos/c7x_1/example.syscfg 

    check for similar entry from app_mem_map.h and .syscfg and manually change the address values.

    Similar steps has to be done for r5f as well mpu_cfg and rat config is taken from syscfg file.

    Regards,
    Gokul
