when i removed uboot customization i am able to update the BUP in my board.
my requirment is to only update uboot using ota.
i see these files are genertaed in payload_t18x directory
bl_only_payload bl_update_payload kernel_only_payload
i think kernel_only_payload will only update my uboot only,can you please confirm i have to install it in my board.we have to copy it in /opt/ota_package and run sudo nv_update_engine --install or any other command.
===========regarding Uboot enviorment variable i was keeping it in mmcblk0boot1 that is causing issue…
i see UBENV partition in flash.xml file of bootloader but i am not able to see this partition on board,can you please guide how i can identify which mmc partition it is using.
