Could you tell me how to change the initial MPU (A72) clock frequency in SBL?
Our customer has modified the SBL source code to change the initial MPU (A72) clock frequency, but the MPU was not running.
They modified the sbl_soc_cfg.h as follows to change the initial MPU clock frequency.
~/ti/ti-processor-sdk-rtos-j7200-evm-07_02_00_06/pdk_j7200_07_01_05_14/packages/ti/boot/sbl/soc/k3/sbl_soc_cfg.h
#if defined (SOC_J7200)
:
:
#define SBL_MPU1_CPU0_FREQ_HZ (1500000000)
They modified the sbl_slave_core_boot.c as follows to make sure that each core clock frequency was changed.

They used the SBL test application to make sure the MPU was running. In the output message log, the MPU clock frequency is set to 1.5GHz, but "MPU1_0 running" is not output.
