以下测试环境为：

• Win10 系统
• 通过 scons --dist 新生成的 qemu 环境
• 每隔 1 秒通过串口 COM9 发送 hello world 的下位机

输入下述命令运行 qemu 程序：

qemu-system-arm -M vexpress-a9 -kernel rtthread.bin --nographic -serial mon:stdio -serial COM9

结果显示系统崩溃，并且是在 qemu 接收第一个字节后崩溃。

下位机不主动发送数据给上位机时，工作正常。

We need to test EMBA on it

Testcases:

• Default/docker installation working
  • EMBA run with profile default-scan in strict mode (-S)
• Full installation working
  • EMBA run in dev mode with options -s -z -S -D -

defmt

defmt::println!("{:?}", 1 as *const u8);

output:

core::fmt

println!("{:?}", 1 as *const u8);

output:

0x1

defmt should also include the 0x prefix.

The current format makes it hard to tell that the number is a hexadecimal valu
