Hello,
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?
Below are some snippets to show the behavior

As you can see the first byte (b4) seems to have been tranfered twice.
fli tells me that I have an 8 x 8 Flash but the working demo reports a
16 x 16 which is what I would expect.
