Can't see anything immediately wrong. Check the trace. Check reset, clock, flash, and power is good. Compare to the examples. I would expect at least 600ms to finish io config

So maybe you're just timing out too early

<@U0404BRGR1C>:  If you are reading from the logic analyzer, then you need to set `la_iena` bits to 1 for the channel(s) you want to read back.  The purpose of the `la_iena` signals is to allow the user project to leave the logic analyzer unconnected without having to worry about floating inputs.  But that means that all data passing from user project to management SoC has to be gated by enable signals that are controlled through the software.

Much appreciated for both your comments. I'll make the changes and see the results.

Still the same problem. Could you direct me to some projects? thanks in advance

I'm using a cocotb testbench to drive it, which might be confusing

You can also give a link to your repo and I can try to reproduce your result

thanks

<@U0172QZ342D> cocotb looks like a nice approach, in your adder example You don't have a video on it on the Z2A site?

Sorry I'm out of time to go further with your test

it looks like it gets to a point and then stops

but it's reading firmware and setting up ios correctly
