Building for a PCA10040 dev board (nrf52832) in SDK 14.0.0 with the S132SD v5.0.0
I'm an encountering an issue where calls to printf() are only displaying a single byte in the terminal emulator.
I am using app_uart_fifo.c and retargeting printf():
.../components/libraries/fifo is in my include paths and everything is building just fine.
My uart_init() is as such:
static void uart_init(void)
{
uint32_t err_code;
app_uart_comm_params_t const comm_params =
{
.rx_pin_no = RX_PIN_NUMBER,
.tx_pin_no = TX_PIN_NUMBER,
.rts_pin_no = RTS_PIN_NUMBER,
.cts_pin_no = CTS_PIN_NUMBER,
.flow_control = APP_UART_FLOW_CONTROL_DISABLED,
.use_parity = false,
.baud_rate = UART_BAUDRATE_BAUDRATE_Baud115200
};
APP_UART_FIFO_INIT(&comm_params,
UART_RX_BUF_SIZE,
UART_TX_BUF_SIZE,
uart_event_handle,
APP_IRQ_PRIORITY_LOWEST,
err_code);
APP_ERROR_CHECK(err_code);
}
NRF_LOG_USES_RTT and NRF_LOG_INFO are set to 0
RETARGET_ENABLED and APP_FIFO_ENABLED are set to 1
UART_ENABLED is set to 1 and configured as such:
The interesting thing is that an arbitrary number of calls to printf() from outside the loop within main() work as expected, i.e.:
printf("APP STARTED!\r\n");
printf("More text!\r\n");
printf("Even more text!\r\n");
printf("Some more text!\r\n");
// Enter main loop.
for (;;)
{
if (NRF_LOG_PROCESS() == false)
{
power_manage();
}
}
However, calls to printf() from within a handler function or any subsequent function will print only the first byte, i.e.:
static void some_write_handler(uint16_t conn_handle, ble_whatever_t * p_whatever, uint8_t data)
{
printf("This will fail...");
if (data)
{
doSomething(data);
}
}
Prints only T, at which point no other characters will be printed, even with subsequent calls.
Any input would be greatly appreciated.
