I try to use MFG tools. MFGtools program below 4Mbytes kernel uImage. but I can't program (to parallel nor) 4.6Mbytes uImage through MFGTools.
I need uImage partitioned 8Mbytes to /dev/mtd2 partition.
I changed parallel nor partition size than compile but It doesn't work on MFGTools.
Mfgtools actually download uImage to target boards.
Are you sure your mfgtools's uImage you changed run at target boards?
You can use mfgtools uImage with other rootfs to enter console to check if partition really enlarged.
there are two uImage , one uImage is in OS firmware folder and the other uImage is in files folder.
if size of uImage in files folder is over 4MB, error occures, of cause small size of uImage works fine.
uImage in OS firmware is partitioned and have 4MB at /dev/mtd2
