@mjs-arm @MaureenHelm assign to right person if it is not related to you.

Could crash somehow related to below error messages ?
[dev/mcr20a] [ERR] configure_gpios: Failed to get pointer to GPIO_MCUX_PORTB_NAME device
[dev/mcr20a] [ERR] mcr20a_init: Configuring GPIOS failed

Yes, I see the problem. It was introduced with #7129

Actually this issue exists for several of the NXP peripherals which still use references to CONFIG_GPIO_MCUX_PORT*_NAME. Enabling any of them currently causes the same BUS FAULT:

• fxos8700 temp sensor
• fxas21002 temp sensor
• mcr20a 802.15.4 radio

NOTE: There are quite a lot of references in doc/reference/kconfig/* as well.
