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. > > Also, you need a recent version of U-Boot (for example 99c2fdab or > later). 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-"?) > > Try something like this: > > => tftp 200000 /tftpboot/tqm5200/uImage > => tftp 400000 /tftpboot/tqm5200/tqm5200.dtb 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? > > Please note that the device tree we have at the moment is for the > TQM5200 only and does not include support for the TQM5200S. > > But probably you just had the same problem - missing or bad console > device specification. > In older kernels it was O.K. just to uncheck the SM501 drivers in the kernel configuration.
