Port 1 pins could not assign on uarte

[wade1987]

When i used Port 0 assigned on Uarte rx tx pin , everything was ok.

But when i changed the rx tx pin to port 1 , for example p1.00,p1.08.p1.09, it doznt work...

i am sure i used the right macro for pin map NRF_GPIO_PIN_MAP().

this problem seems like an previous bug called "Port1 could not assgin on low power pwm",please just search it for sure in devzone.

my sdk is 15.3.0 for zigbee and thread.

Thanks.

Hi

Can you show me how you've mapped and configured these pins with a snippet of your code? I tried finding the bug you mentioned but weren't able to, are you able to share a link perhaps, as I'm not finding it on DevZone.

Best regards,

Simon

Please see the similar bug on this link https://devzone.nordicsemi.com/f/nordic-q-a/39114/uart-does-not-work-on-port-1

By the way, my project is start from nRF5_SDK_for_Thread_and_Zigbee_v3.2.0_9fade31，and the base example is \examples\peripheral\usbd_ble_uart_freertos .

uint8_t UART1_PIN[2][2] = 
{
	//{0 , 26}, //P0.26 rx
	{1 , 8}, //P1.08 rx
	{0 , 27}, //P0.27 tx
};

        drv_config.p_context = NULL;
		drv_config.use_easy_dma = 1;
		drv_config.pselrxd = NRF_GPIO_PIN_MAP(UART1_PIN[0][0], UART1_PIN[0][1]);
        drv_config.pseltxd = NRF_GPIO_PIN_MAP(UART1_PIN[1][0], UART1_PIN[1][1]);
        drv_config.pselrts = NRF_UART_PSEL_DISCONNECTED;
        drv_config.pselcts = NRF_UART_PSEL_DISCONNECTED;
        drv_config.hwfc = NRF_UART_HWFC_DISABLED;
        drv_config.parity = NRF_UART_PARITY_EXCLUDED;
        drv_config.baudrate = baudrate[BaudrateSel];
        drv_config.interrupt_priority = UART_DEFAULT_CONFIG_IRQ_PRIORITY;

		//按drv_config里的配置初始化
		ret = nrf_drv_uart_init(&Uart1Instance,
                            &drv_config,
                            uart1_event_handler);
	    if (ret != NRF_SUCCESS)
	    {
			NRF_LOG_DEBUG("uart1 nrf_drv_uart_init() fail, err_code = %d", ret);
			return SOC_UART1_INITIALNIZE_FAIL;
	    }

Hi

Thank you for specifying. The issue you linked to seems to be specific to the mesh SDK, but I'll check internally to make sure whether it could be present in the zigbee/thread SDK as well or not. In the meantime, are you getting any error messages when using these pins? If so, could you please share what this error is?

Best regards,

Simon
