I have to increase u-boot's partition size on my board to make room for an application to be compiled as part of u-boot binary. I am currently running u-boot version "1.3.1-rc1" and my current NOR partition is as follows:
Partition Address -------------------------------- ---------------- /dev/mtd0 -RCW, 64k 0xFF800000 /dev/mtd1 Kernel 2M 0xFF810000 /dev/mtd2 cramfs 4.8M 0xFFA10000 /dev/mtd3 U-Boot 384K 0xFFF00000 /dev/mtd4 Env 64K 0xFFF60000 /dev/mtd5 EnvB 64K 0xFFF70000 /dev/mtd6 DTB 64K 0xFFF90000
I have updated to Flattened Device Tree to reflect the new partition as follows. Also, I have updated the TEXT_BASE to 0xFFE60000 in the config.mk under board/<my board> directory.
Partition Address -------------------------------- ---------------- /dev/mtd0 -RCW, 64k 0xFF800000 /dev/mtd1 Kernel 2M 0xFF810000 /dev/mtd2 cramfs 4.3M 0xFFA10000 /dev/mtd3 U-Boot 1M 0xFFE60000 /dev/mtd4 Env 64K 0xFFF60000 /dev/mtd5 EnvB 64K 0xFFF70000 /dev/mtd6 DTB 64K 0xFFF90000
U-Boot binary with the updated FDT doesn't boot. So, I need to understand what other updates I need to make for U-Boot to use this new partition. I would like to know if there are standard hooks in u-boot to incorporate partition changes that may be documented somewhere.
My board is powerpc architecture and is using NOR flash to boot u-boot. Any help is appreciated. I can provide more information if needed.
Thanks, Jatin
