Hi,

I developped a TWi driver that runs in a test board with the same microcontroler (the at91SAM9363), then i had tried to run this driver in the reel at91SAM9263-EK board.

The problem is that when i launch the driver, i don't get any error, but don't see the TWI signals in the J24 connector (TWD : pin 10 and TWCK : pin 9).

I supposed that the problem comes from the GPIO configuration, I had set the flowing register for that :
v_pTWIGpio->SYS_PIOB_MDER = 0x30;
v_pTWIGpio->SYS_PIOB_ASR = 0x30;

but I always have the same problem.

any ideas please.
