TLS handshake fails for ESP32S3 in QEMU (IDFGH-14706)

[ShawnHymel]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.4

Espressif SoC revision.

ESP32S3

Operating System used.

Linux

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

None

Development Kit.

QEMU

Power Supply used.

USB

What is the expected behavior?

Complete TLS handshake using mbed-tls library and fetch https://www.howsmyssl.com/a/check.

What is the actual behavior?

The example connects to the QEMU network, gets an IP address, and then fails to connect to the provided website. Unhandled exception occurs (crash) and the processor resets. See log.

Steps to reproduce.

1. Go into the https_mbedtls example.
2. Set configs to enable OpenEth and debugging (idf.py menuconfig or sdkconfig.defaults):

CONFIG_EXAMPLE_CONNECT_WIFI=n
CONFIG_EXAMPLE_USE_OPENETH=y
CONFIG_LOG_DEFAULT_LEVEL_VERBOSE=y

3. Set target to esp32s3:

idf.py set-target esp32s3

4. Build and run in qemu:

idf.py qemu monitor

Log file for ESP32S3

Here is the log file for the ESP32S3 not working under QEMU: esp32s3-https-qemu.log

Working example for other variants

If you change the target to something else (e.g. esp32, esp32c3), the example successfully builds and connects to the provided website.

idf.py set-target esp32
idf.py qemu monitor

As you can see from this log file, the connection process works as expected: esp32-https-qemu.log

Note that building for the esp32s2 with OpenEth fails. I will file a separate bug for that.

[Harshal5]

Hello @ShawnHymel,

The command idf.py qemu uses the latest release of Espressif's QEMU package. Currently the latest release (esp-develop-9.0.0-20240606), and as mentioned in the release notes, adds just the initial support for ESP32-S3.

I am able to recreate the issue by running the example using the command idf.py qemu, but the issue seems to have been fixed in the development branch of QEMU. Probably until the next QEMU version is released, you could try out the ESP-IDF example by building the latest QEMU version manually using the steps mentioned here. Here are the logs for the same: https_mbedtls.log

Thanks!
