Thanks! > I also wonder why all the resets are removed. > Are all the registers reset in another way now? They weren't *all* removed. Just the ones that were causing a problem. The right answer is to add yet another reset signal that handles all the rest, and just toggle that one after the FPGA is loaded. It's a little bit complicated since the FX2 code has some knowledge of those particular registers. Currently we are running with two resets: tx_dsp_reset and rx_dsp_reset. These are designated to reset the appropriate half of the signal processing chain in the FPGA. This includes the corresponding FIFO. In the past, they were also resetting the control registers (FR_*) that were also sort of associated with that half of the signal processing. That was the behavior that was wrong. Just because you wanted to reset the FIFO, didn't mean that you wanted to completely hose all of the rest of the configuration. We also had a problem where one of the resets was resetting the register that contained the resets... That was why initializing the Rx was hosing the Tx, or vice-versa (don't recall which way it went.) In the mean while, the registers that matter to me are getting zeroed from the host code. In your case, you may still want to still reset your register with tx_dsp_reset and/or rx_dsp_reset. Depends on your needs.
