The only version number I can find under boards manager is under:-

"ESP32 by espressif sysyems"
3.0.0-rc1

in additional board manager I have installed:-
https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json

I couldn't see the Olimex ESP32 C3 Devkit LiPo listed in the 'stable' version but I can see it and set it from the developer version.
It is correctly listed at the bottom of the Arduino IDE screen on com6.
Arduino IDE is version 2.3.2

The board info is now showing an Adafruit C3.

I'm trying to upload an image but can't get it to work.

Is there any chance your ESP-PROG board might help?

Edit: disregard, I was looking at the wrong SOM product page.

Hi Lub - I do not see the updated PDF schematic on the product page and I also cannot find any repo on https://github.com/OLIMEX/ for the STMP1 SOM hardware.  In addition to just schematic it would be helpful to know where to find the hardware changelog for this SOM.  For example many of the SOMs are here but not the STMP1.  Thanks.

Ensure that the 5V power supply is stable and within the specified range for the board. Fluctuations or insufficient power can cause boot issues. Check the connection between the SDRAM and the AM3352-SOM. Ensure there are no loose connections, damaged traces, or other hardware issues. The problem might be due to incorrect memory initialization settings. Verify the SDRAM parameters in the U-Boot configuration. Sometimes, incorrect timings or parameters can cause the boot process to hang. If possible, try using a different U-Boot version to see if the issue persists. Sometimes, a different version might have better compatibility with your board.  Cat likes to eat

QuoteI'm using Arduino IDE
Latest 'additional boards manager with the correct board listed.

What is the version of the ESP32 package as listed in "Additional boards maanger"?

What is the board selected (as written in the list)?

Did you try with developer json, instead of the stable one? I've explained it here:

Hi
I can't upload my sketch to either of my ESP32-C3 Dev Kit LiPo boards. I get:-

esptool.py v4.6
Serial port COM6
Connecting...
Chip is ESP32-C3 (revision v0.3)
Features: WiFi, BLE
Crystal is 40MHz
MAC: a0:76:4e:79:a9:60
Uploading stub...
Running stub...
Stub running...

A fatal error occurred: Unable to verify flash chip connection (No serial data received.).
Failed uploading: uploading error: exit status 2


Sometimes it it just says:-
A fatal error occurred: No serial data received.
Failed uploading: uploading error: exit status 2

I'm using Arduino IDE
Latest 'additional boards manager with the correct board listed.
Recognised as the correct board on Com6
but
"Get board info" says:-
BN:Lolin S3
VID : 0x303a
PID : 0x1001
SN : NULL


I've tried different cables and USB ports but no luck.

Laptop running Windows 11.
The board is recognised when I plug it in and the 'charging' LED comes on the board lights up.
When I first plugged them in the boards uploaded ok but not again.

Any help much appreciated.
I'm very new to this so if more info is needed please let me know.

Thanks

I get this error when I run the script.
I think its because the smbus has changed?

Is there a new version of this script? I want to see the board revision of a site that is not failing.

I can only get to the board via ssh sor similar.

ESP32 / Olimex ESP32-PoE-ISO
Last post by folkert - April 19, 2024, 10:00:50 PM
Hi,

How can I use the SD card reader on the Olimex ESP32-PoE-ISO?
Do I require a specific type of SD card?
