ok I have a few UCM’s which the memory is going to read-only. looks like its been a bit of a common problem and i’m dreading more of my customer are going to go this way. So i’m trying to work out a fix.
so i’m assuming the Sandisk NAND is the issue and if i replace it well have a good chip again however i’ll somehow need to reload software so i need to SCP the existing software or if i can get into grub i can create user to rebuild nand.
so i need either an rs232 connection or a monitor port.
now i assume the header on the mainboard is probably a VGA port so trying to get information so i can try and work out whats going on.
any one able to help.
