The problem persists with out using DMA. In fact, without DMA, I can't seem to get any continuous playback. My code is below. Please let me know if I misunderstand...

Removing the loop and using 10 updates gives the following error: https://pastebin.pl/view/79e186da In this scenario the hardware doesn't update at all. Edit: this was run with gate-ware derived from the...

That was indeed the cause of the error. With the host updated, the error no-longer occurs. There are now no errors and still no correct hardware playback.

Indeed, it does not :sweat_smile: Fixed by converting to a list comprehension. The wide interface operates fine at 1.3 MS/s with up-to 500 updates (no DMA).

writing a single burst at 2.55 MS/s using the wide interface and DMA, does update the DAC. However, it does not play back the correct waveform. If I write a...

To be precise, the code below produces the output shown in the table. The ramp exhibits 19 distinct voltage levels. These are similarly, but not equally spaced. This is not...

Running the code above with n=10 results in the experiment not terminating.

> writing a single burst at 2.55 MS/s using the wide interface and DMA I clearly stated I was using DMA. Given the issue name, testing without DMA does seem...

There is clearly a DMA issue. DMA does not work correctly at 1.3 MS/s. Non-DMA writes work correctly at 1.3 MS/s. I can attempt 2.55 MS without DMA. However, this...

Below are 100 update, 2.55 MS/s, linear full scale ramps with and without DMA With DMA | Without DMA --- | ---  |
