PROCESSOR-SDK-AM62X: OTP e-fuse MAC address

Part Number: PROCESSOR-SDK-AM62X

Hi,

In order to e-fuse the address, which of the following process is correct?


./construct_ext_otp_data.sh -extotp ${MAGIC+DATA} -indx ${INDEX} -size ${SIZE}
./gen_keywr_cert.sh -t tifek/ti_fek_public.pem --ext-otp ext_otp_data.bin --ext-otp-indx ${INDEX} --ext-otp-size ${SIZE}

then after converting, i will get tiboot binary file then flash to the board.

Do i need to repeat this step for three times due to the length of mac address?

or is it:


./construct_ext_otp_data.sh -extotp ${MAGIC+DATA} -indx ${INDEX} -size ${SIZE}
./gen_keywr_cert.sh -t tifek/ti_fek_public.pem --ext-otp ext_otp_data.bin --ext-otp-indx ${INDEX} --ext-otp-size ${SIZE}

./construct_ext_otp_data.sh -extotp ${MAGIC+DATA} -indx ${INDEX} -size ${SIZE}
./gen_keywr_cert.sh -t tifek/ti_fek_public.pem --ext-otp ext_otp_data.bin --ext-otp-indx ${INDEX} --ext-otp-size ${SIZE}

./construct_ext_otp_data.sh -extotp ${MAGIC+DATA} -indx ${INDEX} -size ${SIZE}
./gen_keywr_cert.sh -t tifek/ti_fek_public.pem --ext-otp ext_otp_data.bin --ext-otp-indx ${INDEX} --ext-otp-size ${SIZE}

then generate the tiboot binary file then flash it once.
