GPIOTE interrupt initialisation error in Cloud Client

[harisahmed]

Hi,

I have modified the Cloud Client sample from ncs v1.4.0 for sending sensor values to the AWS IoT. The sensor code makes use of GPIOTE interrupts using this sample as a reference. The problem is that while building my Cloud Client sample, I get the following error:

Building ‘zephyr/isr_tables.c’ from solution ‘build’ in configuration ‘Common’
  Combining ‘zephyr/isr_tables.c’
    multiple registrations at table_index 49 for irq 49 (0x31)
Build failed

Following the instructions of the sample reference, I have disabled Zephyr GPIO in the project configuration as well but the error persists. Can someone please take a look at

8726.cloud_client.rar and help me resolve this error. Thank you.

Hello Haris, 

This error tells that you have you configured the interrupt two times. I will have a look at your source, and get back to you.

Kind regards,

Hi Haris, 

My apologies for the late reply. Due to the Christmas holiday our staffing is lower than usual. 

Have you been able to look into your code, following the suggestion that my colleague Simon gave you in case #260752? 

I got the following output when building your project with NCS v1.4.0

gen_isr_tables.py: error: multiple registrations at table_index 49 for irq 49 (0x31)
Existing handler 0x22325, new handler 0x115d9
Has IRQ_CONNECT or IRQ_DIRECT_CONNECT accidentally been invoked on the same irq multiple times?

Hi,

Thank you for your response. I actually found the solution to the problem. I replaced the following line:

IRQ_CONNECT(DT_IRQN(DT_NODELABEL(gpiote)),
				DT_IRQ(DT_NODELABEL(gpiote), priority),
				nrfx_isr, nrfx_gpiote_irq_handler, 0);

with:

IRQ_DIRECT_CONNECT(GPIOTE1_IRQn, 0, nrfx_gpiote_irq_handler, 0);

and the code compiled. GPIOTE seems to work fine now.

Regards,

Glad to hear! I confirm that your solution solved the issue :) 

Have a great day!
