Ok, that is almost perfect. I used this for my bootargs:

---
setenv bootargs console=ttyS0,115200n8 root=1f01 rootfstype=jffs2
reboot=cold,hard
saveenv
---


However, there are still messages about "unknown node type" when booting
(see below). Is that a problem? Also there is a long delay while looking
for bluetooth (which is not present in the hw):

---
Starting Bluetooth subsystem:Trying baud rate 57600...
Set (GPIO,out,clear) via /proc/gpio/GPIO7
Set (GPIO,out,set) via /proc/gpio/GPIO7
No response after reset
No response from BT module
Trying baud rate 115200...
Set (GPIO,out,clear) via /proc/gpio/GPIO7
Set (GPIO,out,set) via /proc/gpio/GPIO7
No response after reset
No response from BT module
Trying baud rate 921600...
Set (GPIO,out,clear) via /proc/gpio/GPIO7
Set (GPIO,out,set) via /proc/gpio/GPIO7
No response after resetNo response from BT module
Can't initialize device: Success
---


However, after the delay, everything seems fine: I can build executables
in the cross compiling environment and copy them over and run them

I will try to remove bluetooth from the buildroot and see if that helps.

It goes on like that for 125 lines (which is more lines then before,
when the boot failed).
