NX_SECURE_TLS_TLS_1_2_ENABLED and NX_SECURE_TLS_TLS_1_3_ENABLED should not be available as check boxes in STM32CubeMX

STM32CubeMX 6.18.0

MCU: STM32H563RIT6

To my understanding, this uses STM32CubeH5 1.7.0

 

Start a new project and enable ThreadX and NetX Duo.

In “NETXDUO Mode and Configuration”, enable “NX Core”, “Crypto” and “TLS”

In configuration, parameter column “NetXDuo” there are check-boxes for:

TLS CORE

NX_SECURE_TLS_ENABLE_TLS_1_1

NX_SECURE_TLS_ENABLE_TLS_1_3

NX_SECURE_TLS_TLS_1_2_ENABLED

NX_SECURE_TLS_TLS_1_3_ENABLED

 

This is a bug.

According to https://github.com/eclipse-threadx/rtos-docs/blob/1e36a62618de3771c973196e7648cba50d19cf1f/rtos-docs/netx-duo/netx-duo-secure-tls/chapter2.md#configuration-options the proper configuration options are

NX_SECURE_TLS_ENABLE_TLS_1_3 Defined, this option enables TLSv1.3 mode. TLS 1.3 is the newest version of TLS and is disabled by default.
NX_SECURE_TLS_ENABLE_TLS_1_0 Defined, this option enables the legacy TLSv1.0 mode. TLSv1.0 is considered obsolete so it should only be enabled for backward-compatibility with older applications.
NX_SECURE_TLS_ENABLE_TLS_1_1 Defined, this option enables the legacy TLSv1.1 mode. TLSv1.1 is considered obsolete so it should only be enabled for backward-compatibility with older applications.

 

NX_SECURE_TLS_TLS_1_2_ENABLED and NX_SECURE_TLS_TLS_1_3_ENABLED (and other preprocessor identifiers named *_TLS_TLS_*) are internal to NetXDuo and should not be touched from outside or provided as compiler arguments. They are set in Middlewares/ST/netxduo/nx_secure/inc/nx_secure_tls.h from the NX_SECURE_TLS_ENABLE_TLS_1_1 and NX_SECURE_TLS_ENABLE_TLS_1_3.

Note that checking NX_SECURE_TLS_TLS_1_2_ENABLED and NX_SECURE_TLS_TLS_1_3_ENABLED doesn’t actually affect the generated code (at least for STM32CubeIDE). Only .mxproject and the .ioc-file are changed.

But it is confusing for the developers. Especially since the latter options do not actually do anything. So they should be removed from the UI.
