Problem has been solved
The weak USB cable was to blame, after replacing the cable with the original Samsung, the problem did not return.
Problem messages are:
"BrownOut detector was triggered" and
"The Guru Meditation" something like Blue screen of Death (BSOD)

after download m5stack-ble black box is resrating in loop with register dump.

I'm making an interface on the M5stack to the car.
I purchased the Vgate iCAR Pro BLE 4.0 interface and installed the BT terminal on the phone.
Through this terminal he tries to send all the codes to the car and see what comes back.
In my opinion it's the only way not to burn yourself.
iCAR Pro BLE 4.0 also supports BL 2.0 and bl 3.0
Below are the codes that I have already decrypted to establish the transmission between the interface and the car

String commandQueue[commandQueueCount] = {
"AT Z", // Reset all
"AT I", // Print the version ID
"AT E0", // Echo off
"AT L0", // Linefeeds off
"AT S0", // Printing of spaces on
"AT H0" // Headers off, on in (debug only)
// Loop from (Alfa Romeo GULIETTA)

"AT PP2CSV01"			// 01 == CAN 29 ISO 15765-4, fixed DLC 8 byte, 	7 orders <commandQueueLoopFrom>
"AT PP2CON"				// Write to eeprom
"AT PP2DSV0A"			// baud rate == 500 / yy "0A" == 50 kbps
"AT PP2DON"				// save eeprom
"AT Z"							// Reset all ?? ATWS
"AT SPB"						// set USER1 protocol
"AT DP"						// Vgate send CAN29/50 ?? ATDPN 
"AT CRA"						// reset all filters
"AT CP18"					// set CAN priority bit to 18
"AT CRA18DAF140" 	// set the CAN Rx address to 18DAF140
"AT SHDA40F1"			// set the Tx Header to DA40F1
"AT AT0"						// adaptive timing control == disable, AT1 == enable
"AT ST19"					// set timeout in 4 msec steps. 0x19 == 100 msec 
"AT CAF0"					// auto formatting OFF, 8 byte, 				

};

I have m5Stack, a small black box with three silver keys and a TFT LCD display.
I can't load anything into m5sstack if I don't give G0 then GND.
I use 7 Pro x32 Win and I use Arduino 1.8.8 or 1.812.
I don't know any other way to program m5Stack under Windows

I have M5Stack.
When I compile my program for Arduino 1.8.12, windows 7 32 bit and I do download with G0 = gnd with a speed of 115200, the program restarts in a circle.
Other speeds don't work.
below the log from the terminal
