Hi, is that possible to compile source codes under uClinux itself, i.e is there a gcc version that run under uClinux? Warm Regards

I&#39;ve tried python, and it is running on nios2. If you still want gcc, you should read gcc.gnu.org .

But you should think twice. Though comiple C program on a nios2 is possible. You need to port a lot of tools before gcc build. It is not pratical with the limited speed and resource on nios2. Did you ever compile on a 66MHz 486 PC? The uCforth is for coldfire uClinux. It can be ported to Nios2. Forth had been used as firmware of Power Mac. Python is ready to run. Perl has some compile errors, but can be fixed. Why do you want to compile program on Nios2? Do you want to develop program without a PC host? Are you tired of downloading? u-boot,nfs,ftp,tftp,telnet are better solutions. Or just want to learn about gcc?

You will compile on PC host and test your programs on nios2. Forget all about python,perl, and forth. Nor should you compile on nios2. If all the works are inside your lab, then you don&#39;t need ssh. It is easier and faster to use telnet. You can telnet your nios2 and get the files from your PC host via ftp. I don&#39;t use jtag download and terminal, too. ( I used them only to write the guide. ) It is much faster to use ftp or nfs. About compilation errors, you should find out where they come and resolve them. There is no big difference in the gcc itself, whether for i686 or nios2. Most problems used to be library and header. By the ways, did you get the buildroot toolchain running on Linux? You might develop and test your programs on PC linux first, and then port to nios2.

you can use u-boot and tftp to download via ethernet.

And if I won't use u-boot, I want to create my own tool for uploading via Ethernet, any suggestion ?

Warm Regards

I think you'd only need U-boot (or redboot) if you wanted to upload a new kernel. If all you want to do is work with user space applications, I'd recommend using NFS.
