ESP-PROG可以上传但是不能调试（之前可以调试）

[zhenghaku]

大家好，我在使用VSCODE+platformio开发调试ESP32。

我买了2个ESP-PRog，其中一个还没开始用就坏了，任务管理器里看不到。

另外一个可以用，挺好的debug了几次都没问题。但是，突然有一天，不能用了，可以上传，我用的是ESP-Prog上传的，但是点调是的时候就不行。程序基本没改过，没有使用IO，之前可以调试，现在就不行，显示：

Error: timed out while waiting for target halted / 4 - 2
Error: xtensa_wait_algorithm: not halted 0, pc 0x40090d40, ps 0x60025
Error: Failed to wait algorithm (-302)!
Error: Algorithm run failed (-302)!
Error: Failed to run flasher stub (-302)!
Error: error writing to flash at address 0x400d0000 at offset 0x00000018
Error finishing flash operation
.pioinit:12: Error in sourced command file:
Error finishing flash operation

我把Error提取出来了，就是这些。

其实上传的时候也有个error：

但是能用没问题。
请问这是怎么回事呀？是不是又坏了？

可以试试看命令行下JTAG能够工作：https://docs.espressif.com/projects/esp ... un-openocd

谢谢，后来不知为啥，又正常可以用了。但是调试的时候有个奇怪的问题，
他经常不能停在我设的断点上，有时候挺在前面有时候停在后面。然后step over也不太灵，进常一下就不知道跑到哪里去了。step into也是的，行为很奇怪。
我下面某一行代码会crash，但是，不能停在哪一行上面也进不去，挺在前面，然后step into就crash了。很奇怪。
