[U-Boot-Users] u-boot.bin size below 50K

[Houda]

Hi,
I would like to know if it is at all possible to reduce the size of the u-boot 
to 50K or less?  I've tried removing all the non-standard commands without 
going anywhere close to 50k! Is there a way to reduce it to very basic form?
thanks,
Hoda

No.

[U-Boot-Users] compile 1.1.2 - at91rm9200

As you can know, we can apply a patch for booting u-boot 1.0.0 from Atmel
SPI dataflash.  Since I know that a new u-boot version is available (1.1.3),
I would like to boot again u-boot from SPI dataflash.  Do I have to apply a
patch? (where can I find it?)


Regards

No patch is needed, just configure it as needed; see the
CONFIG_SKIP_LOWLEVEL_INIT and CONFIG_SKIP_RELOCATE_UBOOT
config options.

Theoretically, yes.

Would it still be u-boot?  The changes likely would be so large that the 
result would not be recognizable as u-boot.

Has anyone done it?  I am not aware of anyone doing it.  The question 
has been asked before but no patches posted saying "u-boot in 50K" so I 
suspect not.

You have the source and a challenge, if you care to accept it ;-)
