PCM Hammer 2 Preview

It reads but seems to have errors. Get lots of Unable to transmit

[antus]

Can you post the debug log of that? I've not seen that before. It seems to still be working but I'd like to know what its trying to do in the background. Does the same operation work with 021? There havnt been any changes to the xpro driver.

Ill try to get the debug log. Seems to have happened in one of the newer releases. Cant remember which one

[sparepartsblazer]

Heres the debug log. Will check a few other versions to see when it happened

Thanks for that. One of the crash issues in the kernel that was found and fixed was actually to do with the checksum function overflowing the DLC chip RX FIFO as the checksum function was doing the whole segment, without flushing the DLC chip. Then the retry requests stacked up until the platform crashed. It would have been worse in car because bus traffic would have gone in to the RX FIFO and gotten stuck during CRC before hitting the normal flash kernel packet filter and being discarded. Now the CRC loop flushes the RX FIFO and we rely on PCM Hammer sending retries until it gets the data. This looks like it could be related to those dropped packets. Harmless, in fact more stable, but if that's it, its more noisy than we want.

So anything after pull request #47 is when problems started.

I think I have fix, I'll test it locally and then push it up. It was the XPro driver was getting confused when it saw that message come in between the transmit and receive. It was harmless, but the driver can be smarter.

Never thought to try my VCX Nano

Fix tested OK
