Hi,
is there any reasonable way to reserve some small flash sectors embedded
inside U-Boot for other usage ?
Example :
2 sectors @ 0-16k U-boot start including initial code @ reset vector.
1 sector @ 16k-24k e.g. environment.
2 sectors @ 24k-40k reserved (small linux mtd partitions).
? sectors @ 40k+ remaining U-Boot code.
Back with U-Boot 1.1.4 I used the board's local u-boot.lds like this :
[snip]...
.text :
{
cpu/mpc5xxx/start.o (.text)
lib_ppc/board.o (.text)
lib_ppc/interrupts.o (.text)
lib_ppc/ticks.o (.text)
. = DEFINED(env_offset) ? env_offset : .;
common/environment.o (.text)
. = DEFINED(CFG_ENV_ADD_SPACE) ? (. + CFG_ENV_ADD_SPACE) : .;
*(.text)
*(.fixup)
[snip]...
The primary goal is to create a dedicated sector holding the auto/boot
script being available through a nested mtd partition.
Since the flash is completely used up there's no chance using sectors
outside of U-Boot.
Any hints are welcome.
Regards,
André
