[U-Boot-Users] PXA250 ramdisk in flash

[Neil Campbell]

Hi,

I have a lubbock(dbpxa250) board which I'd like to boot from flash. I've
burned the kernel image and ramdisk image into flash and try to boot
as follows:

  => setenv bootargs root=/dev/ram0 console=ttyS0,115200
  => bootm 280000 500000
   
both images are verified ok and kernel starts but eventually falls over
when trying to mount root fs.

  Kernel command line: root=/dev/ram0 console=ttys0,115200
  RAMDISK driver initialised: 
  Kernel panic: VFS: Unable to mount root fs on 01:00

I found the setup_initrd_tag and setup_ramdisk_tag functions which pass
the ramdisk info to the kernel but the latter of these if commented out with
a #ifdef 0. Just wondered if anyone has u-boot running ok with flashed ramdisk
on the lubbock board? Or am I doing something wrong in the above steps?

 Thanks,

   Neil

I had this working with ARMboot, but have been booting cramfs for some time 
now. I just tried with u-boot and fail to mount a valid ramdisk. So, it 
probably is a problem with u-boot passing tags correctly. I'll try to take a 
closer as soon as I get a chance.
