Hi.
Please see the solution for this issue here: https://rntlab.com/question/solvedassert-failed-tcp_alloc-idf-components-lwip-lwip-src-core-tcp-c1851-required-to-lock-tcpip-core-functionality/

Hi.
Thanks for pointing that out.
I also noticed that issue.
At the moment, I don’t have a solution besides downgrading the ESP32 boards to version 3.0.7.

Sara

Spoiler alert, in the meantime it seems the current version has evolved to version 3.1.0 and the ESPAsyncWebServer.h library is broken in this version, it seems that the current status is to rollback to the previous version. When you run the ESP32 LED PWM webserver tutorial, it compiles in the Arduino IDE, runs on the device ESP32-S3-Dev1 but the serial monitor returns following error after displaying the IP of the board:

“assert failed: tcp_alloc /IDF/components/lwip/lwip/src/core/tcp.c:1851 (Required to lock TCPIP core functionality!)”

Looking for alternatives to the ESP32 platform, suggestions welcome.

I don’t think that is something the developers would consider but there is a way to quickly change between two or more versions.

The board libraries are installed in “C:\Users\%user%\AppData\Local\Arduino15\packages” and I take a copy of the old ESP library before updating. Then after updating you can quickly swap back by closing the IDE swap the ESP32 folders back and restart.

It’s much quicker than doing it in the IDE

I wish arduino ide would let two different versions of framework exist. I could not install both versions. Updating 2.x projects to 3.x projects seems like something we should not have to do.
With platformio there is a pio/esp-arduino framework that does seem to work well with version 3.x. The platform is configured in the platformio.ini file and is part of the project.

In reply to Jerry. I do not know. I repartitioned the flash to meet my needs(OTA increased, User filesystem decreased. Now my firmware is using about 70% of OTA partition.

In reply to Andreas. Wow thanks,larger comepile size is a trouble as well. What if we compile a simple blink sketch(without including any library). The bin file size still be different?

TFT_eSPI library is broken too.

During compilation it mentions Zigbee and errors out.

Do you have updated code for ESPNOW?
The data receive has changed as well as changing the MAC address.
I am trying to port a sketch from Arduino 1.8.19 and ESP32 1.0.4 by Espressif Systems.
