I checked this. I think the TQM5200 is really hanging after the ...OK 
because I have activated the telnet server and normally I'm able to 
connect to the device after booting via ethernet. No ping, no telnet. 
With an older 2.6.19.2 kernel this was O.K.

I'm using U-Boot 1.2.0-gbc2b9c33-dirty (Feb 22 2007 - 09:53:14). Is that 
recent enough? (I don't know exactly what you mean with "99c2fdab", is 
this the second number after "1.2.0-"?)

Maybe the problem is the missing tqm5200.dtb file. I have booted the 
kernel without it (just bootm 200000). Does the kernel need this file? I 
found a tqm5200.dts file the the kernel sources, but the device tree 
compiler (dtc) seems not to be in the 4.1 ELDK. Do I have to install 
this compiler and build the appropriate dtb file?

In older kernels it was O.K. just to uncheck the SM501 drivers in the 
kernel configuration. Has this changed?

Thanks and bye,
