jemk: and if anybody can boot the board from other media, then they can also read out the secret from the efuse
Sounds like it's good enough to stop most people poking around
jacobgorm: there are i2c secure elements you could use instead to store some secrets
(the link above is the code to use the backdoor, just a 'smc #0' call from fel)
The main reason I wanted to use the secure boot was to have a signed image on SPI flash and not have it super simple to get it to boot anything else but I think I gave up because it looked like the secure boot rom couldn't boot from SPI
dgp: you mean I could attach the secure element over i2c?
jemk: on the H5 it works to read them directly, but must be different for writes then?

lvrp16: I never tried multiple 4K images
somehow my a13 boards dies on http://dpaste.com/17HPRXT (goes into reset) and i can't trace down where pwm-backlight backlight does come from. If i stop it at initrd stage, it works there without issue (so it cannot be some strange watchdog)
jacobgorm: there was some code somewhere in bsp, can't find it right now. I used the u-boot commandline, so no code.

lvrp16: On mainline scaling down images with width greater than 2048 doesn't work yet
but non-scaled 4K should work (others reported that it works)
