thx, but It's STM32101C8 . PD0/PD1 remap on OSC_IN and OSC_OUT pin.

I can't set the PD0/PD1 as output mode !

Maybe this is a bug ,I couldn't resolved it .

I need a demo sourcecode to remap .

appreciate your help .:D

I suppose that you want to remap the CAN on the GPIO D0/D1

//CAN Remappper sur D0 et D1

GPIO_PinRemapConfig(GPIO_Remap2_CAN, ENABLE);

/* Configure CAN pin: RX */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;

GPIO_Init(GPIOD, &GPIO_InitStructure);

/* Configure CAN pin: TX */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;

GPIO_Init(GPIOD, &GPIO_InitStructure);

Pls give a correct example, I can't post my code.

Hi,

Check our last documents on web RM0008 version 4 and Erratasheet version 3 ( May 2008) Let me know if you get more questions on this.

Cheers,

STOne-32.

Hi - am awaiting new board run - perhaps this suggestion may help:

Can't find obvious error in your listing. Would like you to move this

code to two other ''shared pins'' - and see IF the inability to set as

output persists. In this manner you - at least - will see if the problem is PD0/PD1 specific. Again - you must comb your part's pin-outs to find suitable (those which aren't ''natually'' I/O) pins to ''re-map.''
