The block labeled ESP32-S2 is a chip "ËSP32-S2 WROVER model" and I will also check with different USB to UART serial device. Might be the one which I am using now is not supplying sufficient power to ESP32-S2 module. If any other issue I will post in the same discussion.

I have implemented a similar design for a custom board and facing the same issue. the board is ESP32 S2 SOLO. I couldn't use the board in Arduino. The serial monitor prints
"invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffESP-ROM:esp32s2-rc4-20191025
Build:Oct 25 2019
rst:0x7 (TG0WDT_SYS_RST),boot:0x8 (SPI_FAST_FLASH_BOOT)
Saved PC:0x4001276a
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff"

The reset works but the flash button does nothing.
