Tool/software:

hi team,

I have successfully written keys to a SK-AM62B development board using (am62x/keys_devel ) default keys and tried with one short certificate , and device changed from HS-FE to HS-SE .

then replaced smpk.pem from am62x/keys_devel with board/ti/keys/custMpk.pem of yocto build ,and rebuild the uboot.

in build folder there are 3 tiboot3 found (gp,hs,hs-fs) i tried with tiboot3-am62x-hs-evm.bin the its getting reset error.

attaching error log below
