Moved fully installed ubuntu to different location. When plugged back in green light comes on but no blue light indicating disk reads. Went to flash the sd card and efi partition was in read only state. I flashed this and another sd card with ubuntu image and armbain same issue green light only. Tried multiple pd power supplies 30w, 65w. And 5v usb same issue. I tired opening uart no output. I tried maskmode and no usb comes up. Do not think any other way to debug and not sure how to RMA to allnet china.
Rock 5B wont boot
Was maskroom working with same cable, port and computer before?
Unfortunately do not know as had no reason to use prior to issue.
Then nobody knows if it worked before or not,
You may be using wrong cable or just bad drivers. Each rockchip will not come up with cheap accessories.
Have You already updated loader to fix power issue of board?
Hey I am using a known good cable has been used to load roms on many android phones using adb and fastboot. I have booted into ubuntu and lsusb shows phone but when hold maskmode button, plug in and let go nothing shows in lsusb (same as rkdev tool in windows) . I did not update uboot prior to this and unable to do so now. As understand the issue with the pd controller is mitigated by entering maskmode?
“Moved fully installed ubuntu to different location” so your using something more as a sd card ?
and a card flasing on another device and efi partion not writeble , damaged sd due flashing wrong image ?
did you flash the spi for booting before ?
but asume more that you writing sd card wrong .
I had fully running pihole install and was my primary dhcp server. I had ubuntu radaxa fully updated had numerous power cycles in 3d printed case. By move to different location I mean physically moved it and by this meant I had to unplug and plug back in (no issue previously). I had a fully working os and when I plugged back in some spurious writes to the sd card corrupted it and now only output is constant green light, no hdmi, uart,usb otg. I believe is explicitly a hardware issue. I did not update the spi prior to this as had no issues with booting and running multiple os on the board.
so then your spi is empty because it is empty at factory , so bad uboot on spi isnt the cause
when no sd emmc is plugged the board would go to maskrom even without the button ,
green light doesnt say that much as it has 5v . could you check the voltage on the 3.3v gpio pin .
