qemu debug rt-thread error

rt-thread commit: 166c83f37
bsp: qemu-vexpress-a9
toolchain: arm-none-eabi-gcc (15:8-2019-q3-1+b1) 8.3.1 20190703 (release) [gcc-8-branch revision 273027]
QEMU version: QEMU emulator version 5.2.0 (Debian 1:5.2+dfsg-11+deb11u2)

使用qemu-nographic.sh沒有問題，但是用了QEMU-dbg.sh就會報下面錯誤

WARNING: Image format was not specified for 'sd.bin' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

Inizia confrontando qemu-nographic.sh con QEMU-dbg.sh per il BSP qemu-vexpress-a9, utilizzando il commit di RT-Thread, la toolchain e la versione di QEMU indicati. Riproduci il malfunzionamento e verifica perché l’invocazione di debug inizializza ALSA; il lavoro è completato quando lo script di debug si avvia senza gli errori audio segnalati e lo script non grafico continua a funzionare.
