Add new social & board problem

[jyu99]

Hi

I'm trying to add new Soc & board

below is the problem When I use the west build the sample code hello world

[2/134] Generating include/generated/version.h -- Zephyr version: 3.2.0-rc1 (/Users/pswd/zephyrproject/zephyr), build: v3.2.0-rc1-57-gb27c5d73ef09 [8/134] Building C object zephyr/CMakeFiles/offsets.dir/arch/arm/core/offsets/offsets.c.obj FAILED: zephyr/CMakeFiles/offsets.dir/arch/arm/core/offsets/offsets.c.obj ccache /Users/pswd/zephyr-sdk-0.15.0/arm-zephyr-eabi/bin/arm-zephyr-eabi-gcc -DKERNEL -D_FORTIFY_SOURCE=2 -D__PROGRAM_START -D__ZEPHYR__=1 -I/Users/pswd/zephyrproject/zephyr/kernel/include -I/Users/pswd/zephyrp In file included from /Users/pswd/zephyrproject/zephyr/include/zephyr/arch/arm/aarch32/arch.h:20, from /Users/pswd/zephyrproject/zephyr/include/zephyr/arch/cpu.h:19, from /Users/pswd/zephyrproject/zephyr/include/zephyr/kernel_includes.h:33, from /Users/pswd/zephyrproject/zephyr/include/zephyr/kernel.h:17, from /Users/pswd/zephyrproject/zephyr/arch/arm/core/offsets/offsets_aarch32.c:28, from /Users/pswd/zephyrproject/zephyr/arch/arm/core/offsets/offsets.c:9: /Users/pswd/zephyrproject/zephyr/include/zephyr/arch/arm/aarch32/asm_inline_gcc.h: In function 'arch_irq_lock': /Users/pswd/zephyrproject/zephyr/include/zephyr/devicetree.h:326:40: error: 'DT_N_INST_0_arm_v7m_nvic_P_arm_num_irq_priority_bits' undeclared (first use in this function) 326 | #define DT_INST(inst, compat) UTIL_CAT(DT_N_INST, DT_DASH(inst, compat))

I wonder know which file should need to re-write or reconfigured

You likely miss the following in your SoC dts description:

&nvic {
	arm,num-irq-priority-bits = <4>;
};

To be tuned accordingly.
