Hello,
Is not yet an issue with ubidump but in the steps to mount in order to could use it.
Was following the steps to perform the mount but I am struggling at this step.
1) Dumped full NAND using JTAG moving all content into RAM and after dumping into file.
2) Performing "strings" and HEX visualization seems correct dump
3) Trying to mount it as UBIFS but fails in last step.
Output.
