I am trying to get the chibios to run on this board but when I flash the board with the blink example I doesn't seem to work . I have changed the code to use the palSetPad(IOPORT3, 7) so that I use the right port. I'm using the yagarto tool chain and eclipse as my ide. Do I have to configure chibios differently than the example(ARMCM3-STM32F107-GCC).
Probably it is because the I/O pins are programmed for another board, most likely the pin of your LED is programmed as input.
When porting to another board just follow this procedure:
1) Create another directory under ./boards for your specific board then copy inside the files of another STM32F107 board.
2) Edit the board.h file and setup all the I/O pins according to your board schematic (each pin must be programmed as input, input with pull-up, output, open drain etc, info are inside the file board.h). This is the part that requires a bit of work, you have to read the schematic. Unconnected pins should be programmed as input with pull-up.
3) Duplicate the STMF107 demo into another directory, give it the name of your project.
4) In your project modify the makefile in order to refer the new board files.
5) Modify main.c (and you already did this).
5) Compile and run.
If you have trouble just ask.
Thanks for the quick reply. I am still having some problems i have configured my port like this:
* Port C setup.
* Everything input except:
#define VAL_GPIOCCRL 0x33444444 /* PC7…PC0 */
#define VAL_GPIOCCRH 0x44444433 /* PC15…PC8 */
#define VAL_GPIOCODR 0xFFFFFFFF
but i still can't get the diodes to light op.
The defines look correct.
Are you able to debug inside Eclipse? it is important to understand if the code is really executed,
Also verify if the Makefile refers the modified board.h or the original one, note that you have to put the correct path in the makefile and also in board.mk (i forgot to mention this…).
Thanks!!!! that solved the problem :D
Very well :-)
I am thinking to buy that board too, it looks really good.
