How to generate a HUK for STM32MP151CAA?

[bsw]

Hi,

i want to use the secure storage feature of our custom STM32MP151CAA based platform. Therefore i have to write a HUK to the OTP as explained in the STM32MP1 wiki article. But how do i generate a HUK? What exactly do i have to program into the OTP?

Thanks in advance,

Börje
