Dear =?ISO-8859-1?Q?Andr=E9?= Schwarz,
In message 1268321602.4803.24.camel@swa-m460 you wrote:
is there any reasonable way to reserve some small flash sectors embedded inside U-Boot for other usage ?
Yes, of course there is. For example, in many board configurations we use such small sectors for the environment (then called "embedded environment").
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.
This can easily be done.
Back with U-Boot 1.1.4 I used the board's local u-boot.lds like this :
Right. The linker script is the pace that needs to be tweaked.
The primary goal is to create a dedicated sector holding the auto/boot script being available through a nested mtd partition.
Well, I think there might be more efficient ways to acchieve this, but YMMV.
Why are you asking? You wrote you have been doing this since 1.1.4, so where exactly is your problem?
Best regards,
