Hi,
I have a problem as follow:
In my circuit I have a enc28j60 module on SPI .
I setup a Serial interface to PC to show somethings on terminal.
All is ok when I turn on this device when my AVR MKII connected to it(SPI), but when I disconnect MKII and reset it I see leds of enc28j60 blinking abnormaly and it is not working.
I try to find the problem and I see this problem can be solve with this to way :
1- When touch RESET on micro with a wire which connected to GND for a sec.
2- When I comment "(1 << RXCIE )" line , I mean when disable interrupt on USART RX.
I cant find figure out what is main problem.
Thanks in advance for any help.
