How did you achieve this? I need to reproduce it.

RPMB is only available on eMMC cards and I don't have a removable eMMC
card since by definition they are soldered on.

Does it happen on an ordinary MMC card without RPMB?

I'm sorry if I'm ignorant of something very obvious here...

I will read the code and see if I'm missing something obvious.
