hi
after successful opening of UDP socket now I’m facing trouble in DIPR register.
Here is my problem.

While Writing Destination IP through SPI into DIPR and also DPORT register its fine,but after SPI reading it is showing all zeroes in both.
I have checked all the register addresses of DIPR & DPORT registers are correct(In socket ‘0’ DIPR location 0x040C).

May i Know is there any other register bits to set/reset to get DIPR & DPORT working.

Al though all other registers like SIPR,SUBR are reading fine.Only in DIPR & DPORT registers are not working properly through SPI.

Could you please help me…

Thank You.

Hi,

DIPR and DPORT register value is changed after TCP connection successfully.

So, try again after connection established.
