Hello,
I’m facing a problem with UR5e. During restarting or powering the controller freezes on the BIOS loading error message B4. Below is the image of the issue. I know that such an error in the PC motherboards is related to the USB problems, but I don’t know here. Any support is appreciated!
P.S. Cutting the power supply or multiple restarting didn’t solve this issue.
Thanks a lot,
Grzegorz.
I would suggest putting a fresh install of PolyScope on a new SD card and replacing the current SD card. Could be it is faulty. 
If this doesn’t work, you’re probably looking at a new motherboard.
Ok, thanks, I hope it’s only the SD problem :D. And is there any special walkthrough for doing fresh PolyScope installation on the new SD? Or I can follow standard image installation (Like Ubuntu etc.)?
You can follow the standard UR procedure as described here: https://www.universal-robots.com/media/1804841/install-new-image-all-types.pdf
