Hello,

Sorry, gpiote_30 is to confirm if the error is related to the IO port, from the results it doesn't seem to have anything to do with it. RTT still shows the same error. The above is the modified code. Initialization and instances are modified according to the reference documentation. Can you help me understand why this error is displayed? Are there any things to keep in mind when using the BM SDK?

Thank you

Hi Iiu,

In your ISR_DIRECT_DECLARE, you define gpiote_30_direct_isr, but in IRQ_DIRECT_CONNECT you reference gpiote_20_direct_isr, which doesn't exist. This means the IRQ vector is not properly connected, leading to the "Unhandled IRQn: 219" fatal error when the GPIOTE20 interrupt fires. Additionally, you are using GPIOTE_INST = NRF_GPIOTE20, but named your ISR gpiote_30_direct_isr.

Please also check out the example in the NCS BM v1.0.0 Release Notes for Interrupts

Regards,
Amanda H.
