Hello u-boot list!
I am using an Eddy-CPU V2.1 from embeddedmodule.com The u-boot version is 2008.10-rc3:
U-Boot> version U-Boot 2008.10-rc3 (Sep 3 2009 - 18:30:12)
It is basically an AT91SAM9260 with a complete development kit. I am running buildroot-2010.08 on it with linux 2.6.34.3. Everything is working fine and u-boot does the job it should do, except one thing:
If I issue the following command manually, my system gets through to the login prompt and runs up and healthy:
cp.b ${OS_FLASH} ${OS_SDRAM} ${OS_SIZE}; cp.b ${FileSystem_FLASH} ${FileSystem_SDRAM} ${FS_SIZE}; bootm ${OS_SDRAM} ${FileSystem_SDRAM}
This is as well the content of the bootcmd-variable inside u-boot.
All the variables mentioned in this command are correct in their writing (case sensitivity) and their content. Everything is ok so far.
If now I power up the board and let it run on its own without manually issueing the command above, the system boots up to when the login-prompt should come up (I can even see output of two /etc/init.d-scripts just before the login-prompt should be there) but in case of having a running system, the board reboots immediately.
So what is the difference between typing that command manually and letting it run on its own?
Below is the output of printenv - maybe this could be of use.
Thanks a whole lot for any help in advance, Dennis
