Known Limitations

Some project are not generated with STM32CubeMX tool for the exhaustive list please refer to the table available in STM32CubeProjectsList.html
The component “USBX/CoreSystem” must be selected alongside either “USBX/UX Host CoreStack” or “USBX/UX Device CoreStack”.
In NetXDuo, some configuration flags, that are not used in the STM32Cube FW package examples, might be non-functional when combined. This limitation will be fixed in upcoming releases.
Comment error in “MX_WIFI BSP Component” Release_Notes : “The EMW3080B MXCHIP Wi-Fi module firmware version has to be V2.3.4 instead of V2.3.4 rc 13”
The devices MX66UW1G45G and MX66LM1G45G are driven by the same BSP component driver.
The project Tx_FreeRTOS_Wrapper generates a warning (The left and right operands in tx_freertos.c are identical). This warning has no impact on the example functionality.
The Nx_WebServer application works only with O3 optimization with STM32CubeIDE in Debug mode and occasional page loading issues may occur. This known limitation will be fixed in upcoming releases.

Notes

The following sequence is needed to disable TrustZone:
- Boot from user Flash memory:
  - Make sure that secure and non-secure applications are well loaded and executed (jump done on non-secure application).
  - If not yet done, set RDP to level 1 through STM32CubeProgrammer. Then only Hotplug connection is possible during non-secure application execution.
  - Use a power supply different from ST-LINK in order to be able to connect to the target.
  - Uncheck the TZEN box and set RDP to level 0 (option byte value 0xAA), then click on Apply.
- Boot from RSS:
  - Make sure to apply a high level on BOOT0 pin (make sure that nSWBOOT0 Option Byte is checked).
  - If not yet done, set RDP to level 1 through STM32CubeProgrammer. Then only Hotplug connection is possible during non-secure application execution.
  - Use a power supply different from ST-LINK in order to be able to connect to the target.
  - Uncheck the TZEN box and set RDP to level 0 (option byte value 0xAA), then click on Apply.
