JTAG UART slowness

Hi All, I am trying to write a file from the PC into SDRAM through the JTAG UART, and have found that it is quite slow. I only see about 1KB/s, and need to transfer files that are about 10-20...

Hmmm.... If you expose the nios soft reset pins to an avalon slave you should be able to use the JTAG -> Avalon master interface to download software.

This would significantly reduce the resource usage - especially if you don't need the I-cache for anything else.

Technically the JTAG uart could still be present - but I suspect that is only included as part of the debugger.
