Hi!
Adding new environment qspiload which will load zImage and Linux DTB from serial NOR flash. The default flash offset for the images as below and they are configurable during run time.
- zImage located at 0xa0000 with assuming file size 6MB
- Linux DTB located at 0x50000 with assuming file size 28kB
Hmm. Ok, zImage second, so that it can grow. Makes sense. Not sure if 28kB is not a bit small for DTB. I'd reserve at least 64kB.
Yup, it can grow up to 64kB as the size for a sector. We used 28KB mainly for boot time performance.
So why don't you use UBI on the QSPI NOR ? That way, you'd secure the binaries against bitrot as well.
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
Thanks Chin Liang
