[U-Boot-Users] Trouble building u-boot 1.2 with NAND support

[U-Boot-Users] Trouble building u-boot 1.2 with NAND support

[Philip Balister]

I've been trying to compile u-boot with support for NAND flash for the 
Lyrtech SFFSDR board (TI davinci based). I've acquired various davinci 
patches, but keep getting linking errors. Currently, I am working with 
patches from 
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/27603 applied to 
u-boot 1.2, but I ahve also seen this problem with patches based of TI's 
u-boot.

Does anyone have any suggestions? I am really new to u-boot ...

Let me try again, with a specific questions

It seems like libarm in u-boot defines some of the helper functions 
normally found in libgcc. For some reason I am linking against both 
libraries. Maybe there is a problem using an EABI compiler with u-boot? 
Although I build u-boot fine for omap5912osk with the same toolchain.
