程序下载后，按复位是可以正常运行的，并且可以输入命令正确执行
但是通过JTAG调试的时候，openocd读取了一些信息后，会提示drop 'dbg' connection

有时候，串口没多的提示，有时候会提示Guru错误：
Guru Meditation Error: Core 0 panic'ed (Memory protection fault).
Read operation at address 0x50000004 not permitted.

Setting breakpoint at 0x40022340 and returning...

openocd的提示，也是dropped 'gdb' connection

Debug Console的输出如下：

目标芯片是esp32s2

Hi Simon,
Could you try disabling CONFIG_ESP32S2_MEMPROT_FEATURE in menuconfig? It is under Component Config -> ESP32-S2 specific -> Memory Protection.
