[NRF52832][SDK 14.0][Keil] Hardware UART + Ble compilation issue

Great to hear you figured it out. I've found that most errors I get like this (i.e. linker) are due to not having the sdk_config.h file set correctly or missing library source files. You will have to be patient with the SDK, and be prepared for much frustration. It's very poorly documented and keeps changing all the time!

Success !!

Now compilation work well. But still a little bit confused on how to use the SDK. :s

Thanks a lot Jorgen

Try changing the APP_UART_DRIVER_INSTANCE to 0, nRF52832 have only 1 UART peripheral (UART0), and it cannot use instance 1. Only nRF52840 IC support UART1 instance.

#define APP_UART_DRIVER_INSTANCE 0

I assumed to have added the file but no.. Now the error look like this:

And you still have the source file (app_uart.c or app_uart_fifo.c) included in your project?

You right the app_uart was not enabled, now I set app_uart_defined to 1 but the error still remain.

Configuration:

Have you enabled app_uart in sdk_config.h?

#define APP_UART_ENABLED 1

Hi Doug, thank you

Ok, I tried to reduce the Path length but the error still remain. Not sure to understand why the linker doesn't like long path File. My SDK Folder is in my Desktop and the Path to Object folder look like this:

C:\Users\Alexander\Desktop\nRF5_SDK_14.0.0_3bcc1f7\examples\ble_peripheral\Alpha_LoRa_UART_3\pca10040\s132\arm4\_build

What do you suggest ? Alexander

Check the length of your path. If it has too many nested folders, the Keil linker will fail to find some of the object files.
