2011-06-09 15:53:09     NAND boot problem

I create a NAND boot image and I can flash this in just fine.  I can even boot into it by use of the reset button, but when I pull power after I have booted once before, I get this:

 

 

 

NAND read: device 0 offset 0x80000, size 0x480000

4718592 bytes read: OK

## Booting kernel from Legacy Image at 01000000 ...

   Image Name:   bf548-2.6.34.7-ADI-2010R1-svn951

   Created:      2011-06-08  22:26:35 UTC

   Image Type:   Blackfin Linux Kernel Image (gzip compressed)

   Data Size:    5614918 Bytes = 5.4 MiB

   Load Address: 00001000

   Entry Point:  002788b4

   Verifying Checksum ... Bad Data CRC

ERROR: can't get kernel image!

 

 

 

 

 

 

You know what, I wonder if it is because the image is too large and after I boot it scrambles a page or something?  Sound feasible?

the image is loaded to 16MiB, and is way smaller than 16MiB, so the size shouldnt matter

 

you could try nboot

I tried that:

 

 

 

bfin> nboot 0x2000000 0x80000

 

** Device 524288 not available

 

 

FYI, my uboot is in the first three sectors.

Dammit, forgot that there is one more parameter to nboot

Mike, changing my boot paramters to use nboot is working a lot more stabe now.  Thanks for the suggestion.
