A fatal error occurred packet content transfer stopped received 8 bytes - Исправление ошибок и поиск оптимальных решений проблем

I was trying to program my ESP32_CAM module, but every time I got this error:

Has anyone had a similar problem?

This link says it means there is something wrong with the esp file system rendering it «broken»… Not sure if there is a way to fix the issue though.

EDIT:
I found that if I disconnected some of my peripherals from esp32, the error went away. Perhaps too much power was being drawn.

Can’t flash QT Py ESP32 Pico

Trying to reset an Adafruit QT Py ESP32 Pico and am getting the following: (https://www.adafruit.com/product/5395)

A fatal error occurred: Timed out waiting for packet header

Once in a while when I reset the board it «works», as in the current binary will produce correct results on the serial monitor and the BLE app that monitors it.

However, most of the time I get the following output on the serial monitor:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT)

Is there anything anyone can think of to return this to a state that I can flash something to it?

Board

ESP32-PICO-D4

Device Description

Custom PCB — ESP32 Pico D4.

PIR sensor connected to an analog pin, and another sensor connected to I2C — few buttons on a GPIO and RGB LED

Hardware Configuration

SD0-SD3 Unconnected
CMD, CLK Unconnected
IO16, IO17 Unconnected
IO0 only connected to programmer
IO2 connected to LED Anode (But removed to test if this was the issue)
IO12 (MTDI) connected with pull-down (also tested with this removed)

Using an old ESP32 Devkit C with the ESP32 module removed to flash with (connecting TX, RX, EN, IO0 GND to my module)

Version

v2.0.5

IDE Name

Arduino IDE / Espressif IDE

Operating System

Windows 10

Flash frequency

40MHz

PSRAM enabled

Upload speed

115200 to 921600

Description

I’m building a new revision of a prototype of a PCB with an ESP32 PICO D4 on it. In the old revision, I used an ESP32 WROOM module, but due to size issues, I had to change to PICO D4.

I had verified the hardware by running a hello world sketch and uploading it was successful.

Now it was time to upload the prototype firmware, so I changed the board type from Wroom to PICO32 and uploaded the firmware without any issue — But after the firmware was flashed, I could see the following message on the serial port:
`ets Jun 8 2016 00:22:57

rst:0x10 (RTCWDT_RTC_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371`

For now the device «seems bricked», since I cannot upload a new sketch / firmware. I have tried to let it autoconnect, and I have tried with the EN and boot button to flash, but I will get the following message when trying to upload a sketch:
esptool.py v4.2.1 Serial port COM3 Connecting.... Chip is ESP32-PICO-D4 (revision 1) Features: WiFi, BT, Dual Core, 240MHz, Embedded Flash, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: e8:9f:6d:09:8e:28 Uploading stub... Running stub... Stub running... Changing baud rate to 921600 Changed. WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs.
So it seems like after flashing my previous firmware that I cannot connect to the flashchip — normally this is due to stapping pins (which is unconnected), so how can I flash a fresh bootloader when I’m not allowed to upload a sketch?

Sketch

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);

}

void loop() {
  // put your main code here, to run repeatedly:
Serial.println("Hello world!");
}

Hi, I want to use the Micro-SD in 4-bit mode on ESP32-GATEWAY. Based on the schematic, it seems R9-R11 needs to be filled with 0-ohm resistors for this to happen.

Is this correct? My problem is that filling R11 specifically makes flashing fail. Here are the last lines of the flashing attempt log:

Changing baud rate to 460800 Changed. WARNING: Failed to communicate with the flash chip, read/write operations will fail.
