I have two patches against the AVR32 MACB driver in my tree, and it
look like it might fix your issues.
- macb-nonblocking-asf-3.5.1-0000.patch
The MACB driver does not set the correct speed/duplex from MAC to PHY in
case of speed/duplex link change (i.e. if the remote device is replaced
or if a damaged cable make a negotiation restart and set the speed from
100 to 10). Here is my patch against ASF 3.5.1 which fixes this issue as
well as being non blocking if ETHERNET_CONF_USE_PHY_IT is set, otherwise
it behaves the same as before. It is working with or without FreeRTOS.
It was discussed on the avrfreaks forum[1].
- 0001-fixed-crash-if-MACB-failed-to-sent-a-frame-a-failed-.patch
Fix a crash if MACB failed to sent a frame, a failed frame does not set
the USED/OK bit, so the current implementation locked the circular
buffer
Hope it helps ! :)
