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.
