nRF51_SDK_8.0.0 Symbol GPIOTE_IRQHandler multiply defined

[NoRoadUse]

Hi guys, I use old project try to build again in Keil when I installed nRF51_SDK_8.0.0. But I get the:

.\Objects\ble_knob_detection.axf: Error: L6200E: Symbol GPIOTE_IRQHandler multiply defined (by app_gpiote.o and nrf_drv_gpiote.o).

I don't have any idea what this come out. It seem the GPIOTE_IRQHandler conflict define. I already search it and find It's should be in nRF51_SDK > 8.0.0 be happen. But I'm use nRF51_SDK_8.0.0. Why this problem come out?

Here is my install package:

any suggestion is be appreciate.

This is a known issue in SDK8.1 and SDK9.0.

You can find more information and discussion about it here

The reason for this conflict is that the newly written app_gpiote did not make use of the driver available for gpiote, resulting in both implementing their own GPIOTE_IRQ handler. This problem was fixed in SDK10, i suppose.

hi aryan, right now i m looking for this issue and i saw NoRoadUse's question and your answer, i m using sdk9 and softdevice v8 (soft device enabled), in addition, i m using ble_app_template project, and made some modification (simply i deleted buttons_leds_init(&erase_bonds); line and related function above and bsp_event_handler function), in my project i use i2c library to control an acceleremoter (LIS3DH) interrupt. for this purpose, i added void GPIOTE_IRQHandler(void) to my main.c file and there occur some compile errors (multiply defined nrf_drv_gpiote.o and main.o ). are they same problem? (not: i use keil pack installer. ) thanks in advance.

Think about it: If nrf_drv_gpiote already contains a definition of GPIOTE_IRQHandler(), and you add another definition of GPIOTE_IRQHandler() in your main.c then you do obviously have multiple definitions of GPIOTE_IRQHandler() - don't you?!

hi awneil. thanks for answer. yes you are absolutely right. Actually i dont know how i can solve the problem.

[awneil]

Just remove one of the definitions!

You need to merge your IRQ handler functionality to nrf_drv_gpiote IRQ_handler, using some globals variable and forward declarations. It will be easy to do if pins are not conflicting (using same pin in drv and your handler) with the drv and your logic.
