console_getline() on UART1

RE: console_getline() on UART1

CRE — Thu, 13 Jul 2023 15:19:52 GMT

Hi Simon,

My uart_init() function operates on a glable variable which is initialized like this

const struct device *uart = DEVICE_DT_GET(DT_CHOSEN(nordic_nus_uart));

So in my understanding, it concerns UART0 only.

I am moving to another project, and will not be able to follow up on this topic. Hopefully somebody else will.

Best regards

Have you made separate uart_init() functions for the two UART instances, or do you specify that it is the UART0 instance you're initializing at all?

Please check out this case, where a customer had the same error message from uart_callback_set() some months back. Please double check the project configs you've set up to make sure they make sense.

Best regards,

Simon

Hi Simon, thanks for the feedback.

The error code -88 is returned by : uart_callback_set(uart, uart_cb, NULL);

And I confirm that this error does not happen if I disable CONSOLE_SUBSYS and CONSOLE_GETLINE (with no other changes). And then traffic into and out of UART0 works well.

As per your request, here is my overlay file:

Due to the summer vacation period we are currently understaffed, so delayed replies must be expected. I am sorry about any inconvenience this might cause.

Error message -88 points to the function not being implemented or the socket operation being run on a non-socket (depending on what function exactly is returning this error). Can you share some information on what function exactly returns this function? How does the UART0 implementation in your overlay file look?

Can you confirm that the UART0 works as expected if you I.E. set SUBSYS and GETLINE is set to n?

Best regards,

Simon
