v0.4.1 fails to boot on Adalm-Pluto RevC

[plaes]

Seems like something has broken in the support for revC between v0.4.1 (fails to boot) and v0.4.0. Fortunately it's recoverable via dfu.

[daniestevez]

Can you paste the serial port log?

[daniestevez]

Looking at the changes between v0.4.1 and v0.4.0 and thinking about what's different between rev B and rev C, I suspect that the problem is the addition of the axi_tdd in https://github.com/maia-sdr/linux/commit/16511aa10e47b4c7b832d8c8d52d2997cf6baef3. The maia-sdr dts should delete these nodes. I'll build a firmware with this change tomorrow, but the boot log will help me make sure if this is actually the problem.

I'm building a firmware image with the device tree fix: https://github.com/maia-sdr/plutosdr-fw/actions/runs/7430466111

The firmware will be published as an artifact of the workflow when the build finishes. Can you test this on the Pluto rev C?

Yes, this firmware boots and after updating uboot as well, I got maia-httpd working.

Can you paste the serial port log?

This would require tapping into these tx/rx/gnd pins? (I can eventually do it, but not just right now..)

Right now I can provide devicetree dumps from both versions: analog-dts-0.38.txt maia-sdr-dts.txt

v0.4.1 crashes when it attempts to probe adi-axi-tdd:

This would require tapping into these tx/rx/gnd pins? (I can eventually do it, but not just right now..)

The Pluto rev C has UART access on one of the USB ports.

v0.4.1 crashes when it attempts to probe adi-axi-tdd:

What have you done exactly to cause this crash?

Edit: I was reading too fast. I now understand that this is the boot log of the v0.4.1, which is the version that crashes when booting. The crash you get is what I expected.

Haha.. indeed. :dagger:

Closing this, since it has been fixed on v0.4.2.
