What do I do if I upgraded firmware and now unable to complete boot process?

After running the fw_update script and reboot.  If you're unable to complete the boot sequence and your terminal screen matches the attachment/image, there might be an issue with the u-boot not recognizing the kernel version you updated to.  In this case, we recommend reaching out to our support team for assistance. 

Copy/paste each (whole) line needed into u-boot, one-at-a-time:

#To revert to kernel-a and rootfs-a: setenv bootargs 'console=ttyS0,115200 loglevel=4 rw noinitrd mem=64M rootfstype=ubifs root=ubi0:rootfs ubi.mtd=6' setenv bootcmd 'nand read 0x22000000 0x000E0000 0x00280000; run _mtd; bootm' saveenv #To revert to kernel-b and rootfs-b: setenv bootargs 'console=ttyS0,115200 loglevel=4 rw noinitrd mem=64M rootfstype=ubifs root=ubi0:rootfs ubi.mtd=7' setenv bootcmd 'nand read 0x22000000 0x00360000 0x00280000; run _mtd; bootm' saveenv
