Ethernet driver for STM32 CL
Hello Ilija,

Thank you. I've just copied it into cdf file. I hope it's ok and it was your
intention to use your code.

To test ethernet driver I used a simple HTTP server from test module of lwIP

Due to small amount of RAM >64k and no memory bus to connect external memory I
skipped RedBoot.

Exactly.
Best regards,
