Code changings for custom board
Posted: Sun Dec 27, 2015 7:21 am
Hi,
Last night, I worked on my camera project for which I use a STM32F429IIH. So far I was using the STM429 discovery board for development and everything worked fine.
Since I can't look under the BGA package, I don't know exactly if there's a way to check, if all solder joints are correct. But I assume they are because I've already soldered BGA manually and I can flash the memory. So basically it seems to work.
For persons who are interested in:
- Photos of production: https://drive.google.com/folderview?id= ... sp=sharing
- Eagle Project files: https://github.com/DL7AD/pecanpico7/ (At the moment it contains some errors)
Since the code didn't startup, I changed the main to a very simple hello world example:
Since I use a different oscillator (26MHz), I've taken this into account in the board.h. I've taken the board configuration NONSTANDARD_STM32F4_BARTHESS1 and patched the frequency. I can flash the code to the uC memory but the code doesn't start up (No Blinking). Finally I changed the clock to it's internal, but this didn't change it.
Is there something else what I can test on RTOS level?
Regards
Sven

Since the code didn't startup, I changed the main to a very simple hello world example:
Code: Select all
#include "ch.h"
#include "hal.h"
int main(void) {
// Startup RTOS
halInit();
chSysInit();
palSetPadMode(GPIOC, 13, PAL_MODE_OUTPUT_PUSHPULL); // LED 1
palSetPadMode(GPIOC, 15, PAL_MODE_OUTPUT_PUSHPULL); // LED 2
palSetPadMode(GPIOE, 3, PAL_MODE_OUTPUT_PUSHPULL); // LED 3
while(1) {
palClearPad(GPIOC, 13);
palClearPad(GPIOC, 15);
palClearPad(GPIOE, 3);
chThdSleepMilliseconds(500);
palSetPad(GPIOC, 13);
palSetPad(GPIOC, 15);
palSetPad(GPIOE, 3);
chThdSleepMilliseconds(500);
}
}
