I am trying to compile my own U-Boot for microblaze. Version: U-Boot 2013.01-dirty (Jun 19 2013 - 16:26:51) microblazeel-xilinx-linux-gnu-gcc (crosstool-NG 1.15.3) 4.6.4 20120924 (prerelease) GNU ld (crosstool-NG 1.15.3) 2.22.90.20121010
I have demo where Flash access works fine. Verion: U-Boot 2012.10 (Feb 13 2013 - 20:16:43) microblazeel-xilinx-linux-gnu-gcc (crosstool-NG 1.15.3) 4.6.2 20111018 (prerelease) GNU ld (crosstool-NG 1.15.3) 2.21.53.20110813
When I use my own u-boot and try to write to flash I always get
"Flash not erased"
it seems to be a problem that my flash is x16 but recognized as x8.
Are there any Config variables to set the mode to x16?
This is a known problem. Those chips connected in x8 mode are known to currently not work correctly with the common CFI NOR flash driver. Could you please try the following patch:

And let us know if this fixes the problem?
Thanks, Stefan
