Greetings all,
I have been able to port to U-boot 2009 successfully and am able to boot Linux 2.6.27 via NFS using a flattened device tree. I am now stuck trying to boot a CRAMFS version from flash (AMD nor). I found that U-boot1.2 used a MTD map that is compiled for the board. Is this still the way to mount and map the flash in U-Boot 2009?
I have defined the flash partitions in the device tree source, but it does not seem to get used. am I missing a step or a config setting?
Even though Im trying to boot CRAMFS, the console output keeps refering to NFS as mounting point. my Kernel command line is: root=/dev/mtdblock0 ro console=ttyS0,115200
In the console output i dont see ant CFI interaction. I have been throug my board's default_config basing it closely on tqm8548_defconfig but coulf not get the CFI interface to work.
a would appreciate any help, thanks Hendrik van der Kolf
My console output is:
