Hi, I was trying to install Ubuntu on an sd card but the sd card seems to be marked read only. I read on another thread I need to update the fw/bios. I downloaded the zip file but I have no idea what to do with it. From the PDF "APN - BIOS programming using H2OFFT" it seems that there's an assumption the board already has a system installed, which is not the case. Can I update the fw/bios from another system? Thanks.
