Trouble compiling sc126 with Wiznet support #954

Closed mennozon closed 1 year ago

mennozon commented 1 year ago

The README mentions Wiznet 5500 on SPI can be used as an option but I'm unable to compile the kernel if I enable this in config.h

I'm using Debian (tested on both Bullseye and Bookworm) with sdcc280, I assume this is still needed because of the mentioned bugs in #901 and wiki.

Is sc126 with Wiznet w5500 'supported' or possible at this time?

I assume the kernel gets too big when enabling Wiznet but I'm not sure where to go from there.

At the moment you need to drop something else to make it all fit. It's on the long todo list to finish supporting banking networking on Z180

I was able to make it fit by disabling i2c and sdcard support, FUZIX now detects the Wiznet device and it is working, thanks!
