Hi
I found the UNC20 (
formatting link
) for getting started with ARM7 architecture and uclinux. However the price for a developer's kit, including one module, base board and adapted uclinux, is about three times that of just the module alone. So I wonder if I could begin with just buying a module.JTAG cable and power supply aren't problematic. Regarding the Ethernet magnetics I'm currently trying to get some samples for another project anyway. But for the software... Most of the links I found regarding uCLinux on ARM7 respond very slow or don't load at all, and I don't know exactly what has to be done to make it run on the UNC20 (utilizing the NetSilicon NS7520 ARM+NET). And I don't know if the flash on the UNC20 is supported by any free JTAG tools (preferably running under Linux).
Maybe you can help me to answer the arising questions:
- Does the current uCLinux, hopefully that one with 2.4 kernel, run on the UNC20 with not too many modifications? I see a net driver for the NS7520 in CVS...
- Is it possible to program the flash on the UNC20, using only freely available JTAG tools and a simple JTAG cable (e.g. for parallel port), or do I need extra information that only Forth Systeme knows? On the pictures provided on the unc20.net site I cannot see which flash chip they're using.
- Is it possible to debug software on the UNC20, utilizing JTAG? I assume that once uCLinux is running and can use Ethernet, a GDB server could be started to debug applications. But the OS and its drivers itself?
Thanks for your comments in advance!
