Esp32 Flash download problem

Postby YouJungChoi » Thu Dec 09, 2021 3:17 am

Hello.

I am currently using the esp32-wrover-E product. And I am using version 4.1.1 of esp-idf which is published on Github.

I want to update the firmware of esp32-wrover-E.

The tools currently used to update the firmware are as follows.

<PC OS: Windows 10>

1. Eclipse+ esp-idf plugin

2. esptool cmd tool

3. esp Download tool v3.8.8

The strange thing is that among the ESP32s I have, only those that have the flash vendor 20h : N/A flash devID : 4017 information are downloaded.

flash vendor:
20h : N/A
flash devID:
4017h
QUAD;64Mbit
crystal:
40 Mhz

The information about the ESP32s I have that cannot be updated with firmware is as follows.
(1)
flash vendor:
C8h : GD
flash devID:
4017h
QUAD;64Mbit
crystal:
40 Mhz

(2)
flash vendor:
FFh : N/A
flash devID:
FFFFh
N/A;N/A
crystal:
40 Mhz

If you know the cause or solution for the firmware download failure, please let me know.

Thank you.
