Good point. Its a nice enhancement as we were using raw access for the images in NAND and QSPI. Will add a new command for fs support once we enable the ubifs support in socfpga
Why can't this be enabled now then ?
Mainly for backward compatibility as customer might have their own script on programming a blank flash in production. This is the same where we can do mmc load or a load (with file system).
Does that imply that we will have to get stuck in the past because some random customer of some random company might have a random script somewhere? :)
Haha nope, we still need to advance. Just that we are giving choice for classic and new :)
Can you check if we can do both then? With the option to prefer the new one?
Sure as you already give me a jump start :)
Check the attached patch, it should give you an idea how to load files from UBI/UBIFS on QSPI. It even enables mtdparts for the QSPI, which is cool too.
Cool, thanks for the pointer.
Thanks Chin Liang
