I have met the same problem mentioned in the other u-boot topic, just wonder do we have any solution to this? Or any updated u-boot image? ( I did upgrade from the LNI's u-boot, and the printout for the memory mentioned is below.

Hi ramp

Is it the problem I saw with shihsungs uboot?

I can't quite remember, but I think it stopped rebooting after I followed his manual instructions to flash it (did you run upgrade from LNI's?)

Looking back (pages 4,5), I had to compile ncb from U-boot following shihsungs procedure too. Not that that helps apart from to connect to it.

Hope that helps

Yes it is the same problem you met. I guess your healing is to clear the data part of the uboot, but I believe it should not be necessary, there must be something wrong in the uboot to read some unused bit in the data area. ( the NC work fine with me, I am using a windows porting of the NC)

For the rest are all zeroes. The only meaningful part is the first 4 bytes, can Shihsung do some investigation on that?

Ah, I see the problem! To workaround just do "setenv silent 1; saveenv". BTW, the first 4-bytes is just the checksum of the environment settings.

I have fixed the problem and updated the U-Boot image http://sites.google.com/site/shihsung/l ... ects=0&d=1. There is also a new version based on u-boot-2009.11 http://sites.google.com/site/shihsung/r ... oc/hd-hlan. You can also find the new kernel image based on linux- there.
