Hello! I have recently bought an BPI-R3 and have already installed OpenWRT 23.05.2 on the NAND and then on the eMMC. The next thing I wanted to do is to use all available size of the eMMC, because right after installation only a small part of it was occupied by partitions and their respecting file systems.
I have spent 3 or 4 days figuring out how all the partitions and file systems on eMMC work and why is it designed that way. Why is it so complicated to just resize the partition and expand the file system? How to do this the correct way, maybe i should create separate partition on the eMMC instead of expanding root? Is there any scripts that automatically manage the partitions/resizing/free space on bootup?
So many questions, but so little answers, OpenWRT documentation is not helping either as it looks pretty much outdated and is not being updated with relevant information. I would be very grateful if someone could give an explanation on how everuthing works… I am still relatively new to OpenWRT (previously had it installed on Rpi4 + USB SSD), so please don’t throw rocks at me
