After confirming the SBL’s x509 certificate no longer contains the debug extension for JTAG unlock, the next step is to build the SBL within the PROCESSOR-SDK-RTOS. In order to do so please navigate to the <pdk_path>/packages/ti/build/ directory and open a command prompt. Next, the following make commands should be executed in sequential order without any build errors:
make sciclient_boardcfg_hs BOARD=j721s2_evm CORE=mcu1_0 OS=linux
make pdk_libs BOARD=j721s2_evm CORE=mcu1_0 OS=linux
make sbl_mmcsd_img_hs BOARD=j721s2_evm CORE=mcu1_0 OS=linux
cp packages/ti/boot/sbl/binary/j721s2_evm_hs/mmcsd/bin/sbl_mmcsd_img_mcu1_0_release.tiimage /media/<xyz>/boot/tiboot3.bin
