actually I've some problems to run several commands (flash, flash_erase). The ESP32-WROOM is soldered on a breakoutboard. If I
run flash, program is terminating with Invalid head of packet after some writing on the Chip (baudrate 115200). The output is:
There is more appaering a liittle strange. The output of esptool chip_id is:Serial port COM10

And the output of esptool flash_id is:
But why is Detected flash size: Unknown? Doesn't the modul have flash or is it corrupted? Is that the reason for "Invalid head of packet "?Serial port COM10
