Hello,
In my project i am using nrf52840 with my custom board and to upload the code through NRF_CONNECT application with soft device its uploading properly but with segger emmbedded its giving some error like this .please have look and let me know what is the problem.
after this i have add DEBUG in preprocessor definition and i got this
thank you.
Hello,
NO, still same problem i have checked with LOG function configurations also, when comment out the uart_init then it advertising properly and when i uncomment it its not working. so i think in the uart_init() declaration for two UART is not correct so can you please have a look once on uart_init() and let me know any issue with declaration.
static void uart_init(void)
{
uint32_t err_code1;
app_uart_comm_params_t const comm_params1 =
{
.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,
#if defined (UART_PRESENT)
.baud_rate = NRF_UART_BAUDRATE_115200
#else
.baud_rate = NRF_UARTE_BAUDRATE_115200
#endif
};
uint32_t err_code2;
app_uart_comm_params_t const comm_params2 =
{
.rx_pin_no = RX_PIN1,
.tx_pin_no = TX_PIN1,
.rts_pin_no = RTS_PIN_NUMBER,
.cts_pin_no = CTS_PIN_NUMBER,
.flow_control = APP_UART_FLOW_CONTROL_DISABLED,
.use_parity = false,
#if defined (UART_PRESENT)
.baud_rate = NRF_UART_BAUDRATE_115200
#else
.baud_rate = NRF_UARTE_BAUDRATE_115200
#endif
};
APP_UART_FIFO_INIT(&comm_params1,
UART_RX_BUF_SIZE,
UART_TX_BUF_SIZE,
uart_event_handle,
APP_IRQ_PRIORITY_LOWEST,
err_code1);
APP_ERROR_CHECK(err_code1);
APP_UART_FIFO_INIT(&comm_params2,
UART_RX_BUF_SIZE,
UART_TX_BUF_SIZE,
uart_event_handle,
APP_IRQ_PRIORITY_LOWEST,
err_code2);
APP_ERROR_CHECK(err_code2);
}
thank you.
Hi
Okay, I think you have to use the nrf_drv_uart_init() function to initialize the UART1 instance, as the app_uart does not support two UARTs, and the UART1 is recommended to access through the HW driver, while the UART0 can be accessed through app_uart (or the driver).
Best regards,
Simon
Hello ,
sorry for the late reply,
I think you have to use the nrf_drv_uart_init() function to initialize the UART1 instance, as the app_uart does not support two UARTs,
As before i mentioned i have declared two nrf_drv_uart_init() in fifo.c but it gives me error so that's why i asked how to declare two UART's i think i am repeating the same thing again and again . please let me know how to declare two UART's and use it.
thank you.
Hi
Sorry, but you can check out the Serial Power Library example with two UARTEs that is in the nRF5 SDK v16.0.0. It was removed for later versions for some reason, but should show how to set up two UART instances. Here's the source code:
