Talk:Kernel:BeagleBoard Quick Start

I've tried to use the binary images provided with the Kernel Taster Kit but when it boots it asks for a password. Has anybody an idea what the password is?

I connected the BeagleBoard only using the Mini-USB cable to provide power and use /dev/ttyACM0 as the device for the terminal.

I've added kernel trace and come up with the fact that there is a FAULT that I receive (FAULT: TPS65950 SpuriousInt). Can this be somehow related to the fact that I didn't connected anything to the board except the RS232 to my computer?

catalin, I haven't tried playing with the kernel on the beagleboard yet but since your kernel is faulting you are getting the password prompt for the debug monitor, which should be "replacement" (at least it was so in the past :)). You should be able to able to do some post morten operations once you are logged into the monitor.

@catalin

I have tested it on a Revision C3 Beagleboard. Which revision did you use?

Thanks Echegmik you were right, that was the password and I managed to enter the debug monitor. Now I have to figure out the output that it gives. @Gbraad - I'm using also Rev C3 BeagleBoard. The odd thing is that Angstrom runs flawlessly on it. It may be that my TPS65950 IC on the board is faulty somehow, but I still hope that's not the case.

Having (quickly) looked through the source tree, it seems like the console/tshell logic is nicely separate from the actual device the output goes to. How hard is it to change the stock beagleboard build to have the textshell come out on serial along with the kernel tracing?

I got same TPS65950 fault when using external 5V power supply (I am using Rev.C3 board). I also noticed that I only get this error right after power cycled the board. However, I didn't get the error after hard reset.

BTW, is it possible to bring textshell to serial?
