[U-Boot] SECURE_BOOT on mx6qsabrelite

[Roger No-Spam]

Hi,


I'm trying to enable CONFIG_SECURE_BOOT for an i.MX6 board (mx6qsabrelite). The image boots and seems to be working fine until I do a 'saveenv' command. Then my u-boot image stops working. My initial guess was that CONFIG_ENV_OFFSET was too small, leading to a 'saveenv' command overwriting parts of the u-boot image on the MMC memory card. However, if I increase CONFIG_ENV_OFFSET the size of the signed u-boot image created by the CST tool increase by the same amount. What configuration change do I need to make in order to make 'saveenv' work?


I'm using u-boot-2017.09
