Hi,
the reason for this problem is the definition of
#define DATAFLASH_BUSY 0x00 #define DATAFLASH_OK 0x01 in the file /include/dataflash.h.
All functions return DATAFLASH_OK and in the file /common/cmd_nvedit.c
function do_saveenv()
return (saveenv() ? 1 : 0);
than cause an error.
I have modified it to return (saveenv() == 1 ? 0 : 1);
and this works for my, but i'am not sure if this is the best way of fixing the problem.
Regards
Rainer Berns

Hi Rainer,
i use the autoscr command to store further information in a NAND at the first start. After this it modify the bootcmd and save the enviroment and the last command should restart the device.
Where is your environment located? What parser do you use, i.e. "regular" or "hush"?
The script works fine but "saveenv" seams to abort the script file. I have used different memory location, i have checked the memory contents and i have placed saveenv at the beginning, middle and at the end of the script. It allways abort after "saveenv". I use Uboot 2008.10.
I presume there is a bad return code somewhere. If you have the hush-parser enebled, try this for a start:
=> if saveenv ; then echo ok ; else echo failed ; fi Saving Environment to Flash... Un-Protected 2 sectors Un-Protected 2 sectors Erasing Flash... .. done Erased 2 sectors Writing to Flash... done Protected 2 sectors Protected 2 sectors ok =>
Cheers Detlev
