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

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
Christian

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 ;-)
