Wiznet issues - Githubissues

Hey there,

I am facing some issues using the W5500 and rcbus-z180 implementation:

The file saved by htget is mangled - it includes the start of the response repeated. (see example output later)
dns lookups don't work (/etc/resolv.conf is set correctly)
```
dig google.com
timeout: Invalid argument
```

I initially thought this was going to be an issue with the wiznet FDM code we added last year (didn't do much testing at the time), so I invested in a buspirate and have been testing with that and get largely the same results, both in builds with VDM with CS connected and FDM modes and CS tied low.

One difference between EmulatorKit and the real hardware is on EmulatorKit htget keeps going indefinitely, wheres on the real hardware you get the same content repeated a couple of times before it stops.

Not sure if the dig and htget issues are related or not?

I understand you are busy with other things, but wondered if either of these issues rang any bells? Or if you have any debugging tips? (I think I need to add some logging to htget and work on understanding the SPI trace output)

Thanks!

htget output:
