Hello,

 

I am having trouble boot from NAND flash larger images. Previously my kernel
uImage was around 1.4 megs.  I just recently enabled some other options and
it grew in size to 1.6 megs. 

 

Our nand flash layout is like this.

 

0x00000000-0x00018000 : "UBL image"

0x00018000-0x00044000 : "U-boot image"

0x00044000-0x00208000 : "Kernel image"

0x00208000-0x003ffc000 : "JFFS2"

 

So we have more than enough space. I load the uImage into ram using tftpboot
and then nand erase/nand write it out making sure I write all of it and
erase enough space.

 

However when I go to boot it I get the following:

 

Loading from device 0: <NULL> at 0x2000000 (offset 0x44000)

   Image Name:   Linux-2.6.10_mvl401-davinci_evm

   Image Type:   ARM Linux Kernel Image (uncompressed)

   Data Size:    1646412 Bytes =  1.6 MB

   Load Address: 80008000

   Entry Point:  80008000

## Booting image at 80700000 ...

   Image Name:   Linux-2.6.10_mvl401-davinci_evm

   Image Type:   ARM Linux Kernel Image (uncompressed)

   Data Size:    1646412 Bytes =  1.6 MB

   Load Address: 80008000

   Entry Point:  80008000

   Verifying Checksum ... Bad Data CRC

 

 

However, if I just bootm after I loaded it with tftpboot it works just fine.
So there is some problem in the reading/writing to the NAND flash.  

 

Any thoughts?  

 

Thanks,

 

Josh
