qemu debug rt-thread error

[TaiJuWu]

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.

好像不会，

或者你可以对qemu-nographic.sh做简单的调整，在qemu-system-arm的命令行后面加入-S -s来让qemu进入调试等待模式

這個方法試過了哦

那这个就有些不清楚了呢，可能需要自己仔细看看环境相关的因素。
