new 05def1bef testing: add case for irqprio, should only work with qemu
MPS2_AN500
05def1bef is described below
commit 05def1befc1dddcd0ef754836759e698357d9e54
Author: buxiasen <buxia...@xiaomi.com>
AuthorDate: Sat Aug 10 01:11:32 2024 +0800
testing: add case for irqprio, should only work with qemu MPS2_AN500
MPS2_AN500 have UART1,2,3,4, TIMER0,1, is a great board to do irqprio
test.
enable CONFIG_ARCH_IRQPRIO, and use
'qemu-system-arm -M mps2-an500 -nographic -kernel nuttx.bin'
to lauch qemu
