chibios hal without RT

[noodlefighter]

i try to use chibios/hal without rt-kenerl on stm32f103c8t6
but the interrupt does not work(i set a breakpoint in the ISR but never reach there)
everything works well when i use RT OSAL..

ChibiOS_3.0.5(in fact i had tried the latest version 16.1.4)
arm-none-eabi-gcc 5.2.1 20151202

i try to fit the example "testhal/STM32/STM32F1xx/UART" to bare-metal like this..
it only print out a line: "Starting..."

Code: Select all

#include "hal.h"

static void txend2(UARTDriver *uartp) {
  (void)uartp;
  osalSysLockFromISR();
  uartStartSendI(&UARTD2, 12, "Running...\r\n");
  osalSysUnlockFromISR();
}

static UARTConfig uart_cfg_1 = {
  NULL,
  txend2,
  NULL,
  NULL,
  NULL,
  38400,
  0,
  USART_CR2_LINEN,
  0
};

int main(void) { 
  halInit();
//  chSysInit();

  uartStart(&UARTD2, &uart_cfg_1);
  
  uartStartSend(&UARTD2, 13, "Starting...\r\n");
  
  while (true) {
    osalThreadSleepMilliseconds(500);
  }
  
  return 0;
}

Hi,

You need to enable interrupts after you perform halInit(), interrupts are disabled on main() entry. See the demo HAL-STM32F407-DISCOVERY.

Code: Select all

/*
 * Application entry point.
 */
int main(void) {

  /*
   * System initializations.
   * - HAL initialization, this also initializes the configured device drivers
   *   and performs the board-specific initializations.
   */
  halInit();

  /*
   * Enabling interrupts, initialization done.
   */
  osalSysEnable();

thanks a lot. really works!

Glad to hear it.

Anyway let us know how it goes, HAL alone is not a common use case, most use the whole package.
