Hi Team,

What is the function of custMpk.crt file. How to generate this file using customer own key？

custMpk.crt is located in ti-u-boot/board/ti/keys. Now I repalce custMpk.pem by my own .pem.

It can sign tiboot3.bin tispl.bin and u-boot.img. But cannot generate fitImage, I suspect there is something wrong with this file

Best Regards,

Zane

Hello Zane,
One example to convert dev.pem to dev.crt
openssl req -batch -new -x509 -key keys/dev.pem -out keys/dev.crt
