flash read err, 1000 on ESP32 Wroom Develpment Board

[lalitahuja33]

I'm getting this error on my esp32 wroom dev borad

Code: Select all

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
flash read err, 1000

the code is uploaded successfully I get this on the serial monitor and when I press the boot button the below error comes and it stops.

Code: Select all

rst:0x10 (RTCWDT_RTC_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download

And it just stops there. It looks like esp is not able to read the flash memory. It is possible that the read-write cycle of flash memory has been used completely?

When I googled it, most of the people were having this problem because of GPIO0 pin not having a 10k pull-up resistor on esp chip. But I'm using a dev board and the boot button which is connected to GPIO0 has a 10k internal pull-up resistor.

And nothing is connected to the dev board. I uploaded the "sntp" code from esp-idf and got the same result. And also uploaded the WiFi scan code from Arduino IDE but got the same errors. It's strange because it was working fine the who;e day but suddenly stated giving this error.

Hard to say. Are you sure you don't have anything connected to the GPIOs the flash is connected to? (GPIO6-11)

@ESP_Sprite Nothing is connected to any of the GPIOs of the ESP32 dev board. I think somehow the eFuse is set and the board got bricked. I can't upload code to it. So I have started using a new dev board.
