UART and SDK 10

[Shannon]

I have migrated a new project from SDK 9 to 10, and now I seem to be having issues.

I'm using the uart_fifo to read data from a GPS, so the data shows up every 1 Second.

I believe everything is going okay, until I put a breakpoint in and stop the code, I then get an overrun error, which I believe I've handled in my uart_callback function. by clearing the interrupt and event_error which the SDK should be doing already. The error seems to persist, and I cannot get any new data out of the hardware fifo.

In version 9 of the SDK there wasn't an issue with the error interrupt, the code would continue to run as if no problem occurred. Is this an issue with v9 or v10, which is now causing me problems.

and what do I need to do to ignore the over run error.

This may be a bug in the SDK similar to this. Try to change app_uart_fifo.c with this file: app_uart_fifo_mod.c (only added (void)nrf_drv_uart_rx(rx_buffer, 1); at line 65).

In your project file, there is compiler include folders, these will allow the compiler to pull in any file that is in "#include"ed for from these folders, for instance ../../../components/drivers_nrf/config This should be available some place from within your IDE to modify or add them. Because I'm using Crossworks, and I haven't used Keil I'm not sure where it would be in there. I have used IAR, but I don't have it at my current location. so you may want to consult your compilers documentation to find where to change your include folders. you could in your main.c file define these 2 variables, they are just defaults, in case you don't define them properly in your uart0_init call.
