ESP32-C3 fatal error on installing micropython

[ctvarlan]

Hello everyone,
The first try to put micropython on an older ESP32-C3.
The command is:

>esptool.py --chip esp32c3 --port COM4 --baud 460800 write_flash -z 0x0 esp32c3-usb-20220117-v1.18.bin

and the messages are:

esptool.py v4.3
Serial port COM4
Connecting....
Chip is ESP32-C3 (revision v0.2)
Features: WiFi, BLE
Crystal is 40MHz
MAC: 7c:df:a1:43:10:58
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 460800
Changed.
Configuring flash size...

A fatal error occurred: esp32c3-usb-20220117-v1.18.bin requires chip revision 3 or higher (this chip is revision 2). Use --force to flash anyway.

I tried --force and the result is the same.

What should I do?

Thank you for your attention,

Hi there. What board are you using now? Have you tried using older esp tool? Try using version 3.3

Hi, Thank you for your response. My board is ESP32-C3-DevKitM-1. I just installed esptool 3.3, and I'll give it a try. I let you know how it goes. Thank you,

I gave it a try with esptool 3.3. The flashing was smooth, but the surprise came after. At boot (I'm using Thonny), there is an infinite loop with this content: Build:Sep 18 2020 rst:0x3 (RTC_SW_SYS_RST),boot:0xc (SPI_FAST_FLASH_BOOT) Saved PC:0x403d1232 SPIWP:0xee mode:DIO, clock div:1 load:0x3fcd6100,len:0xe3c load:0x403ce000,len:0x6dc load:0x403d0000,len:0x28ac entry 0x403ce000 E (34) ESP-ROM:esp32c3-20200918 Build:Sep 18 2020 rst:0x3 (RTC_SW_SYS_RST),boot:0xc (SPI_FAST_FLASH_BOOT) Saved PC:0x403d1232 SPIWP:0xee mode:DIO, clock div:1 load:0x3fcd6100,len:0xe3c load:0x403ce000,len:0x6dc load:0x403d0000,len:0x28ac entry 0x403ce000 E (34) ESP-ROM:esp32c3-20200918 Any clue?

Hi, there.
Can you build micropython from source code on Ubuntu?
If yes, try following steps may help you:

1. Checkout micropython v1.18.

git clone https://github.com/micropython/micropython.git -b v1.18

2. Setup esp-idf with ci.sh.

cd micropython/tools
. ./ci.sh
ci_esp32_idf44_setup
. ./esp-idf/export.sh

3. Apply attached patch v1.18-for-esp32c3-rev-2.zip. This patch changes required minimum revision 3 to 2.

cd ..
unzip v1.18-for-esp32c3-rev-2.zip
patch -p1 < v1.18-for-esp32c3-rev-2.patch

4. Build micropython.

make -C mpy-cross
cd ports/esp32
make submodules
make BOARD=GENERIC_C3_USB

5. Deploy micropython to your esp32c3.

make BOARD=GENERIC_C3_USB deploy PORT=/dev/ttyACM0

I'm sorry that I couldn't test this because I don't have ESP32C3 revision 2, but these steps worked with ESP32C3 revision 3.

If you want to use latest version of micropython, please replace step 1 and 2 with the following:

1. Checkout micropython.

git clone https://github.com/micropython/micropython.git

2. Setup esp-idf with ci.sh.

cd micropython/tools
. ./ci.sh
ci_esp32_setup_helper 142bb32c
. ./esp-idf/export.sh

Step 3 to 5 are the same as above.

Hi yn386,
I'll give it a try, and it would be a completely new path for me, doing the build from scratch (source).
I hope it will work with Mint, I don't have Ubuntu.

Thank you and I will let you know,
