[U-Boot-Users] MPC8349-mITX-GP and MontaVista Linux

[Andy Pont]

Hello,

I am trying to get MontaVista Linux Pro 5.0 to run on
the Freescale MPC8349-mITX-GP reference platform using
U-Boot 1.3.2-rc2.  When I try to start my kernel I get
the following output:

MPC8349E-mITX-GP> bootm $loadaddr - $fdtaddr
## Booting image at 00a00000 ...
   Image Name:   Linux-2.6.18_pro500-8349itx
   Created:      2007-10-22  19:02:12 UTC

compressed)

OK
WARNING: could not create /chosen FDT_ERR_NOSPACE.
ERROR: /chosen node create failed - must RESET the
board to recover.
Resetting the board.

Is this error a problem with the way that U-Boot is
setting up the FDT or is it a problem with the way my
Linux kernel is interpreting the information that the
bootloader has given it?

If it makes any difference the kernel and FDT file
were built using the MontaVista LSP for the non-GP
version of the 8349-mITX as that is what they
currently support!

TIA.

It's U-Boot.  As a workaround, there are dtc options you can use to add
extra space to the dtb.

Hi Andy,

The above error is from u-boot and is indicating that you don't have 
enough free space in your fdt blob to add the /chosen node and properties.

The best solution is to use the "-S" and "-R" parameters to dtc to 
create a blob with enough extra space in it to hold the necessary 
information.
