We are engaged in the bring-up of a custom board powered by a AM4378BZDN100S (high security device) and need a quick tutorial with steps to sign the MLO, U-Boot without having to fuse the SMPK, SMEK and SMPK-Hash. A practical example showing the steps, scripts to invoke, with example arguments to the scripts etc. would be most useful. Our aim is to first get an image booting.
Thank you in advance for your help!
