Help to get a U-Boot dump (no replies)

Hi all,

I have a WD EX2 Ultra, and I need the help who has the same box, and the u-boot updated.

I’ve solder the uart interface but it doesn’t work. I don’t know why, but I don’t get anything when the nas boot up. I press space, 1, all the combinations available,but nothing works. I have tested the connections several times, and it seem they are fine. WIth a multi tester I see there is connectivity between the two sides, and I don’t know what else I can do to fix or figure out what is going on here.

After one week, troubleshooting with @bodhi in this thread https://forum.doozan.com/read.php?2,132015,133249,page=3#msg-133249, (many thanks!!), and seeing that it’s imposible that the WD boot with the new kernel and the ram disk without the u-boot updated, I need a dump of that partition ( /devmtd0) to flash my hand.

I’ve seen that CyperPK or vzhilov could help here, but I really appreciate it if anybody who has updated the u-boot, could help me here.

I am open to try anything to get the console working too.

Many thanks in advanced.

Best
