[En-Nut-Discussion] nut/os for avr32 many bugs

[power ip]

hello

I tested ethernut for avr32(EVK1100)

1.SDRAM controller initialization bug in crtavr32.S,After 40-60 minutes of
work, SDRAM data errors.Use atmel code to initialize SDRAM controller,
troubleshooting

2.In ostimer.c file the, AVR32_COMPARE register value error, resulting in
sleep function is not accurate, slower than the specified value.

    //Set_system_register(AVR32_COMPARE, compare);

The following is the correct:
Set_system_register(AVR32_COMPARE, 60000UL);

3.ethernut5.1.0 the gpio function may not be correct, macb not initialize
properly.ethernut5.0.2 ok
