nRF54L15 DK Board
BM-SDK-V1.0
Hi：
I have debugged the IRQ according to the nrfx demo, but now there is an unresolvable error that requires assistance.
This is an error printed by RTT：
00> [00:00:04.744,266] <err> os: Unhandled IRQn: 219
00> [00:00:04.744,285] <err> os: >>> ZEPHYR FATAL ERROR 1: Unhandled interrupt on CPU 0
00> [00:00:04.807,684] <err> os: Halting system
This is my test code. When I use nRF54 DK press button 0 or 1, an error pops up:
