Xiao Esp32S3 COM Port beeps nothing happens

[Homoki]

Hi Guys,

After flashing my Seed Xiao ESP32s , the computer beeps constantly, like when you slide the USB plug in and out.
In the router, the connected devices list show that the module has been seen by the router, but now it's inactive. The MAC address is OK. I have not managed to log in once. I hear just beeping. The device does not show up in the Windows wifi contact list either.
I tested the device with a simple Wi-Fi Arduino Sketch. The device Wi-Fi is OK.

Message from Flash download tool: It seems to be OK:

Code: Select all

Uploading stub...
Running stub...
Stub running...
Changing baud rate to 115200
Changed.
NO XMC flash  detected!
SPI_BOOT_CRYPT_CNT 0
SECURE_BOOT_EN False
Compressed 1467200 bytes to 969586...

 is stub and send flash finish

What is wrong?
Thanks in advance for your helpful replies!

What exact build did you upload to the device?
How much flash memory is installed on the board?
Does the board have PSRAM installed?

You can also use the WebFlasher from https://td-er.nl/ESPEasy/latest/ (requires Chrome or Edge browser) to install a more recent build then available from Github releases page. It also offers a Console option to get more usable logging directly from the device.

If the board has a 'boot' button (connected to GPIO-0), can you keep it pressed while connecting to USB and keep it pressed till the flashing has begun?

And please also try the web flasher: https://td-er.nl/ESPEasy/latest/
(Chrome on Windows, other browsers like Edge may work, but not tested)

If your computer keeps playing the 'USB device plugged in" sound, then it is possible your USB port isn't able to supply the peak currents which are required when starting WiFi.
Or the USB cable might not be the best match to your setup. (either too thin wires, bad contact, etc)

So please also try to use a different USB cable and/or plug directly in a port on the PC or use a powered USB hub.

Hi guys

thank you for your prompt answer.
My xiaoESP32S3 has 8M RAM.
I uploaded a new file with web installer:20241025 MAX8M1M LittleFS ETH [ESP32-S3/C6]
The annoying beeping is gone.
I'm not sure it is the right file, but i have a new Wifi: MAX-ESP32
Tried login with

espconfig

configesp

, but it won't let me in.


The cable must be ok. I tested many other devices all day without any problem.
That was my upload earlier: ESP_Easy_mega_20240822_normal_ESP32_4M316k.factory.bin

The problem is now the password.

[Ath]

The all lowercase "configesp" should be the correct password for the WiFi AP.

You can also use the Console option from the web flasher, and issue these commands to connect the unit to your WiFi, once you see the console log:

Code: Select all

wifissid,<your_wifi_ap>
wifikey,<your_wifi_password>
save

You should fill in the SSID and password for your local WiFi network (do not include the angle brackets), the password is, as usual, case-sensitive.
Each command is sent with the Enter key.

After the Save command, the unit should connect to your wifi. Using the command ip you can see what ip-address is assigned via DHCP to the unit. (and it's also shown in the log, but that can scroll out of view quite quickly)

[TD-er]

Via the web installer you can also let the ESP scan for WiFi and then enter the credentials.

Just for completeness as you now managed to flash it apparently.

That was my upload earlier: ESP_Easy_mega_20240822_normal_ESP32_4M316k.factory.bin

That file is for the ESP32 (classic)
You now have the ESP32-S3.
You also mention you have the ESP32-S3 with 8 MB RAM (Probably PSRAM, not the size of the flash, right?)
If you have the 8MB PSRAM version, you almost certainly have 16 MB flash, which means you should actually use the 16M flash MAX build with OPI PSRAM build to be able to use all the flash storage you have.

The web flasher can test for MCU type (ESP32-S3 vs. ESP32 for example) but it cannot detect the flash size.

Please check if you have uploaded the correct firmware.

Hi Guys,

thanks again!
Problem solved!!!

The solution was selecting the right flash file + Web installer + PATIENCE: The new WiFi hotspot appeared just after 10 + restart.
-The ESP32S3 variant was not included in to the downloaded *BIN files list on Git Hub. That was the reason for false flashing.
-My 1st. attempt was WEB installer from Vivaldi browser. It did not work. It would be nice to put a short warning for the right browser on your WEB page.

My board has 8M on chip + 8M PS RAM,
I'm not sure if 20241025 MAX8M1M LittleFS ETH [ESP32-S3/C6] is the optimal bin file, but it works.

Thanks for your help!

Hmmmm do you have a link to that board?
I have not yet seen boards with 8M flash and 8M PSRAM.
Since the S3 is a bit tricky to what firmware file is flashed when you have PSRAM on the board, I would like to look into that board to see how the flash and PSRAM is wired to the ESP chip internally.
If you flash the "wrong" build on an ESP32-S3 with PSRAM, the board will enter a boot loop and keeps crashing at boot.
This won't damage anything, it is just an annoyance.

This is the link to board.

This variant is an overkill for EspEasy, but it has very small footprint as your thumb. Xiao boards are ideal for small sensorsnodes everyvhere discretely in the house.

[Ath]

Ah, that's one of the few S3 boards with both 8MB Flash and 8MB PSRAM.
Couldn't find info on the PSRAM connection type (Quad vs Octal mode), but most likely it's Quad, as Octal (OPI) can go into a boot loop when not configured appropriately.
