If you look at Kconfig, it says the following.

bool "STMicro STM32 G0"
select ARCH_CORTEXM0
---help---
STMicro STM32G0 architectures (ARM Cortex-M0).What is NVIC_SYSH_PRIORITY ?
Can someone please tell me?
#define NVIC_SYSH_PRIORITY_MIN 0xe0 /* All bits[7:5] set is minimum priority */
#define NVIC_SYSH_PRIORITY_DEFAULT 0x80 /* Midpoint is the default */
#define NVIC_SYSH_PRIORITY_MAX 0x00 /* Zero is maximum priority */
#define NVIC_SYSH_PRIORITY_STEP 0x20 /* Steps between priorities */First, I thought the boards/Kconfig file needed to be fixed.
Is it correct in this way?
config ARCH_BOARD_MYBOARD
bool "BBC Micro:bit configuration"
select ARCH_HAVE_LEDS
select ARCH_HAVE_BUTTONS
---help---
This options selects the board configuration for BBC Micro:bit.
