Hi Bikash,

The recovery image is not supported by default on the JB release for AM335x.
You can try to build it by changing TARGET_NO_RECOVERY in the BoardConfig.mk file.

device/ti/am335xevm/BoardConfig.mk:

-TARGET_NO_RECOVERY := true
+TARGET_NO_RECOVERY := false

Please let me know if this fix your issue.

Hi, I am able to generate ramdisk-recovery.img and kept it in recovery partition, but it is not booting in recovery mode. I think we have to do some change in bootloader , can anyone help in what to modify in bootloader so that it will boot from ramdisk-recovery.img. Is FOTA/OTA or any recovery mechanism has been implemented in sitara platform.

Hi,

During rebooting in recovery mode, one register is updated with recovery command, that register is checked in bootloader and based on that, the bootloader boot from recovery partition. I checked in am335x TRM, I didn't find any clue about the register address. Please help in find the recovery register.

Thanks

Hi Bikash,

You can implement this by writing a blob into a partition, and checks for that blob in bootloader to decide whether to enter recovery or boot normally.
