Hi,
I've been developing a Matter device based on the nRF5340 SoC, and have been using the DK up until now. We've been developing a custom board in parallel. I've created a board definition for our own board, but when trying to run the application it crashed with a kernel panic indicating there's a 802.15.4 serialization error when it tries to communicate with the net core:
E: IPC endpoint bind timed out ASSERTION FAIL [0] @ WEST_TOPDIR/zephyr/drivers/ieee802154/ieee802154_nrf5.c:1152 802.15.4 serialization error: -6 E: r0/a1: 0x00000004 r1/a2: 0x00000480 r2/a3: 0x20010580␍␊ E: r3/a4: 0x20016af0 r12/ip: 0x00000000 r14/lr: 0x00035983␍␊ E: xpsr: 0x69100000␍␊ E: s[ 0]: 0x00000000 s[ 1]: 0x00000000 s[ 2]: 0x00000000 s[ 3]: 0x00000000␍␊ E: s[ 4]: 0x00000000 s[ 5]: 0x00000000 s[ 6]: 0x00000000 s[ 7]: 0x00000000␍␊ E: s[ 8]: 0x00000000 s[ 9]: 0x00000000 s[10]: 0x00000000 s[11]: 0x00000000␍␊ E: s[12]: 0x00000000 s[13]: 0x00000000 s[14]: 0x00000000 s[15]: 0x00000000␍␊ E: fpscr: 0x000c1c14␍␊ E: Faulting instruction address (r15/pc): 0x00091790␍␊ E: >>> ZEPHYR FATAL ERROR 4: Kernel panic on CPU 0␍␊ E: Current thread: 0x20010580 (main)␍␊ E: Halting system
When I try running the application on the DK (also using the custom board definition) it does boot correctly.
I'm pretty new to the nRF53 and the multicore setup, so could you give me some pointers as to where to start looking for this problem? Is this a hardware problem, or configuration considering the code does work on a DK?
Kind regards and thanks,
