Marvell Uboot hanging on modules detected.

Postby bignellrp » Sat Apr 04, 2020 5:33 pm

I need some help unbricking a DS414r1 where the power was removed during a firmware upgrade. I managed to get to the console and got the following errors:

*** Warning - bad CRC, using default environment

Wrong Image Format for bootm command
ERROR: can't get kernel image!

So i loaded the kernel back on by downloading the latest 414 firmware from Synology, unpacking the pat file and using a USB formatted with rufus to fat16 to copy zImage and rd.bin

Great i thought, its booting. It booted back to the DS login page but when i rebooted the console now gets stuck at "modules detected"

Is there a way to get back to the Marvell>> shell from here? Will it time out looking for modules? Is there a key i can press on the keyboard when it boots to go straight to Marvell shell?
