Okay, it only works if the HDD has a MBR partition table, not with GPT. I added a 4TB WD Blue with GPT partition table and the scsi reset commands hangs when trying to find the WD Blue. I am digging through the Marvell github to see if there are updates to GPT, ext2/4 or AHCI that can be patched to the u-boot code distributed by WD. No luck so far.by Storm - Debian
I checked with a 3.5” WD Blue. It is found during ‘scsi reset’. Files are shown by ext2ls.by Storm - Debian
Good news, the box can boot from SSD! To achieve this I did the following: Changed the partition table on the SSD from GPT to MBR. Somehow u-boot cannot handle GPT partition tables, see also this post. I referred back to booting from SSD instead of USB, as described by Gisab on his Github page. I replaced the 'ide reset' commands in his instruction with 'scsi reset'. Afterby Storm - Debian
Short update. I managed to get it working by changing the partition table on the SSD from GPT to MBR. A similar issue is described in this post. Instructions to do the conversion with gdisk can be found here. Using the expert options i zapped the GPT table, only MBR remaining => SSD can be found in u-boot after 'scsi reset'.by Storm - Debian
Thanks Bodhi. Bootlog and printenv output is below. This output is from a u-boot compiled from the WD sources u-boot-2013.01-2014_T3.0p2 and GrandTeton-20170708.patch, as explained here https://github.com/vzhilov/WDMC-Ex2-Ultra/tree/master/1.UBoot. After flashing NAND with the built u-boot I updated the bootcmd as mentioned on vzhilov's Github page. There are some environment variables tby Storm - Debian
Hi Bodhi, thanks for the quick reply. I know it has been booted successfully by others, I read most of the topics concerning the WD EX2 Ultra on this forum :-) It seems that the procedures used in that topic from 2020 by CyberPK and vzhilov do not work anymore on these devices that had a WD OS5 upgrade. Or at least, that is what vzhilov suggests in a post from 2021 https://forum.doozan.com/by Storm - Debian
Hi all, I am trying to install Rootfs Debian-5.13.8-mvebu-tld-1-rootfs-bodhi on my WD My Cloud Ex2 Ultra, but failed to do so yet. Short summary of what I did: Soldered wires to the onboard UART so I have terminal access via a USB to UART converter and minicom. Upgraded stock WD OS3 to OS5 (Maybe nog a very good idea in hindsight..) Upgraded uboot using instructions and image from CyberPKby Storm - Debian
No success either, it hangs after the 'scanning bus for devices' message. I will try the USB route for now. Marvell>> scsi reset Reset SCSI AHCI init for unit0 Target spinup took 0 ms.

Hi Gisab, I have a question about the guide you have written to install Debian on a WD EX2 Ultra. I am stuck at the uboot section, the 'ice reset' command does not show SATA devices. I have attached a SSD to the board but the device cannot be found. Any clues on this?
