Hello, I'm using C6455. When I'tried to load ndk example client to check it I get message EMAC OPEN ERROR. Earlier it was works. What can be wrong?
My problem was resolved.
I have used the EEPROM bootloader so I have written to the EEPROM memory.
When I anilized example's code, I saw that MAC-address of the Ethernet is read from the EEPROM. So (when I wrote to the EEPROM I have overwritten that part of memory where MAC-address was stored) I got incorrect MAC-address. When I changed first byte of it to 0x00 Ethernet began to work.
