- Could you provide any details on what your FLASH procedure is and what you are seeing when you try to boot?
What bootmode are you configuring for FLASH boot?
This will allow us to reproduce the problem here.
Thanks.

- Yes, MLO & u-Boot were rebuilt for DDR3 and ran fine on the 3354 w/ DDR3 booting from SD card.

- Errr.... any more details than that???
The MLO and u-Boot images must be updated for the 3354 DDR3 configuration. Are they using the correct version of the MLO and u-Boot?
What is the FLASH procedure [edit] being used?
-Mike
- Customer states that they are having difficulty flashing MLO and U-Boot into the 3354-GX-X38 module. No issues encountered when flashing MLO and U-Boot in the 3359-GX-226 module.

You should be able to take the myconfig and copy it to the .config.
In theory you could edit the myconfig, but generally it's better at that point to run menuconfig and select... - MF 01:36 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: SATA not recognized

You can print the kernel config file by running:
_zcat /proc/config.gz _
You can then search the output:
_zcat /proc/config.gz | grep SATA_

There should be no reason that the drive isn't detected by Windows XP when using a USB to Sata adapter. Assuming you know the adapter works with other drives, it is possible the drive is bad. - MF 09:20 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: SATA not recognized

I found this command that works in testing the contents of memory. Is there any way to get that value into
a param?
if itest.l *80000000 == 80800020; then echo error; fi;
Thanks,

I think that unless it is an easy port of updating/saving the u-boot environment params(like in I need to be

u-Boot doesn't really have much for interpretative type scripting. I don't think you can accomplish this with the stock u-Boot.
