FPGA Development: RE: Signal Tap & JTAG FPGA Programming
- Hi Dan,
Yes it works with the rbf file and it works when I program it in Linux. No problems there.
I managed to get it programming with the JTAG.
Thanks again for your help!

I've just created a wiki page for the steps that it takes to program the FPGA using the USB-Blaster, would you mind trying that and telling me where it fails and at what percent of the progress bar it fails at?

I'm raised the issue before regarding programming the FPGA with JTAG.

You can search the kernel source for the messages by using grep. For example I might search for the string "msb first" and look at what files are found containing that text. You could then comment out those print statements. - MF 01:18 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Accessing SPI1 bus
