Hi, We use small part of our flash to hold config data (last sector of the flash) and which image must be started. PPCBoot read this and start the right image. when upgrading , we change the kernel option to the failsafe kernel, do the update of the second kernel (the working one) and after that we change the kernel option again and we try to start the new one. We use also a kind of watchdog feature in case of system lockout.
