52840 NCS UART DFU

[yi hung wu]

Hi

 I am currently working with my project with 52840 and i am using sdk v3.0.1 & toolchain v3.0.0 to develope.

 I am learning how to use DFU over UART from the application in Devacademy l9/e2 , it works fine using the example , after that i try it on my own project but because my project use one uart only , so UART DFU and my APP use the same uart(UART0) , and i added two config

CONFIG_SHELL=y

CONFIG_MCUMGR_TRANSPORT_SHELL=y

also init uart0 in my application 

void uart0_init(void)

{

    uint32_t err =  device_is_ready( dev_uart0 );

    if( err != true )

    {

        printk("\nUART_init_err = %d\n", err);

    }

    uart_irq_callback_user_data_set(dev_uart0,uart0_irq_callback, NULL )

   

    uart_irq_rx_enable( dev_uart0 );

}

i use Auterm(v0.35a) to Get image , Auterm data keep running into my uart0_irq_callback , not into MCUMGR shell

is there any way to let my application uart and uart dfu use the same uart and the same time without deinit the uart ? Thanks!

Hello,

Sorry for the confusion, and thank you for clarifying it. In this case, what you have done, disabling the UART IRQs is correct. Have you enabled MCUmgr for UART DFU? I recommend checking the prj.conf file from the sample I shared in my previous response; you can find it here. If you are enabling all these configurations, please share your prj.conf and device tree overlay files so I can take a look.

Kind regards,
Abhijith
