Also, on a related note, if you need to program the GFE, the GFE is using the first set of USB pins on the LPC, where as the olimex board is using the second set. To build the code for the GFE you'll need to add -DLPC2378_PORTB to the list of compiler flags and re-compile. My line looks like this: -I $(LPCUSB_COMMON_DIR) -D LPC23xx -DLPC2378_PORTB
Also, the GFE use the other set of CAN pins as well. My code has the following to init the pins: + + FIO0DIR |= (1<<4);//Set P0.4 to an output pin to allow for enabling of the CAN tranceiver + FIO0CLR = (1<<4);//Turn on the can tranceiver + + PINMODE0 = (PINMODE0 | (1<<0) | (1<<2)) & ~((1<<1) | (1<<3));//disable pullup and pulldown resitors + PINSEL0 = (PINSEL0 | (1<<0) | (1<<2)) & ~((1<<1) | (1<<3));//Set P0.0 and P0. into RD1 and TD1 mode + initializeCAN(CAN_BUS_1, brp, sjw, tseg1, tseg2, sam); I also recommend bumping up the stack space allocated to the task. The minimal stack size is usually too small and leads to non-deterministic problems - xTaskCreate( blinkyLightTask, ( signed portCHAR * ) "usbCounter", configMINIMAL_STACK_SIZE, NULL, mainCHECK_TASK_PRIORITY - 1, NULL ); + xTaskCreate( blinkyLightTask, ( signed portCHAR * ) "usbCounter", 1024, NULL, mainCHECK_TASK_PRIORITY - 1, NULL ); Please let me know if you have any questions, Thanks, -Dave On Fri, Apr 29, 2011 at 10:20 AM, Dave Camarillo <dave.camari...@gmail.com> wrote: > awesome! that's the exact one that we need to test with...
