NRF Toolbox with NRF52 Eval Board

[saravana0210]

I am using nRF52810 Eval board for our project. I am using NRF toolbox UART function to control the PWM and UARTE function . I have tested PWM and UART separately with NRF toolbox UART App and working fine.

 

I try to combine both feature but while compile finding issues. Please refer the errors below i get for more details.

 

1.UARTE0_UART0_IRQHandler function is working without nrfx_prs.c and nrfx_uart.c under nrf drivers sections

2.PWM is working with nrfx_prs.c and nrfx_uart.c under nrf drivers sections

3.When i combine both PWM and uarte in ble_app_hts_pca10040_s132 iam getting compilation error as:

  multiple definition of `UARTE0_UART0_IRQHandler';

  Output/Release/Obj/ble_app_hts_pca10040_s132/nrfx_prs.o:

  C:\Users\99002568\Downloads\DeviceDownload     new\nRF5SDK1702d674dde\nRF5_SDK_17.0.2_d674dde\modules\nrfx\drivers\src\prs/nrfx_prs.c:81: first defined here

4.if i delete nrfx_prs.c and nrfx_uart.c files in ble_app_hts_pca10040_s132 to make the UARTE0_UART0_IRQHandler work

  iam getting compilation error as:

Can you please guide us to fix the issue.

Hello,

Please try to disable the UART legacy support as Jørgen suggests in this post: https://devzone.nordicsemi.com/f/nordic-q-a/48318/multiple-definition-of-uarte0_uart0_irqhandler.  This should fix the multiple definition error you're getting for the IRQ handler.

Best regards,

Vidar

hi,

I tried disabling the UART legacy support and also followed the link which you shared but still same issue.

[Vidar Berg]

Hi,

Maybe it's a different issue then. Are you able to share your project here so I can take a look?

Hi,

i have shared my project, Kindly go through it.

Hi,

Are you using the nRF52 DK (pca10040)? The project you sent me is configured for the nRF52832 chip, not the nRF58210 as stated initially. You should have started with the "pca10040e" project if you are targetting the nRF52810 (see Developing for nRF52810 for more information)

[saravana0210]

Sorry, it is nRF52832 chip NOT nRF52810

No problem, thanks for confirming. There are multiple declarations of the UART IRQ handler because there are 2 driver implementions in your project, one SDK driver, and one custom. PRS is also not needed here  (what is PRS?)

Here are the changes I had to make to build your project:

Notice that logging over UART has to be disabled as well as it depends on the nordic UART driver. You can use RTT instead.

It worked!

Thank you for your help
