file transfer over JTAG UART

Hi all,

I need to transfer a file from the PC to the Nios II on a custom board over the JTAG UART. Is there any way to have the IDE (5.1, but could use 6.0 if needed) open the file on the PC, then write it out to the SDRAM on the custom board using the JTAG UART?

So far, the only way I've seen to load a file on the Nios is through the flash programmer. Is this true? There is no network connection/ethernet/etc on our board. Does anyone have knowledge in setting up a board description file? I think this is currently preventing us from accessing our flash - but so far I am putting that problem off for another day.

Thanks!

Dave

    Will the host based file system help you out?

    This is a faclity that allows file access by coding file open/close/read/write instructions in to your Nios code that access the file system on the PC via the JTAG connection.

    Agreed. The host filing system is a great way to go for running experiments. There's a software example found in the Nios II kit, as well...

    In the Nios II IDE, select New Project and then the "host filing system". Follow the directions in the source file, and you should be good to go.
