Tool/software:
Hi, i am trying to use the python uart uniflash tool from the mcu_plus_sdk_am62x_11_00_00_16 toolkit.
I have put my key in the tools/boot/signing/custMpk_am62x.pem file, and build the entire SDK with ` make DEVICE=am62x DEVICE_TYPE=HS -sk`
however when flashing the uniflash_stage1 file i still get the following output:
(.venv) [fred441a@FSH-arch boot]$ python uart_uniflash.py -p /dev/ttyUSB0 --cfg=sbl_prebuilt/am62x-sk-lp/default_sbl_ospi_nand_hs.cfg Parsing config file ... Parsing config file ... SUCCESS.
