hi dear all:
I have some problems while building the l4env.
I downloaded the snapshot "source-2007-06-30.tar.bz2" from http://os.inf.tu-dresden.de/opentc/download.xml and I tried to build the whole l4 environment in SUSE linux 9.3. But it seems something wrong. The build process is a dead loop, it seems will never stop. I don't know what's the reason. Can you tell me what should I do? By the way: I can build the L4 kernel successfully.
thanks a lot for your help and suggestions!
Best regards! Huang

Not only the configuration but also the code. You probably need to write a e.g. UART driver for your platform. As I said, I don't know which UART is used on your board. Can you tell which type of UART is used there?
There is a UART (RS232 port) which can communicate with PC. how to add that UART driver in fiasco? are there any other platform dependent things that need to touch the code?
thanks for your reply

Looks good to me. You could try a sysrq-t and see if there's something interesting. Also booting with initcall_debug=1 could also squeeze out some more info. Otherwise I'll try getting the public repo up to date again to see further.

You need to add a new platform. Basically you can do the same thing as it's done with the integrator platform. The UART implementation goes to src/lib/uart/arm, and need to be hooked in src/kern/arm/kernel_uart-arm.cpp.
are there any other platform dependent things that need to touch the code?
Most likely. The PIC implementation goes to src/kern/arm/pic-arm.cpp, and the timer goes to src/kern/arm/timer-arm.cpp. Other files to look at are Modules.arm to specify the label to build under and probably rules.cml to add a new platform. The CPU specific things may also need adaptions.
