Embedded Wizard with Lizard Board

Question

I am using the Actron Lizard Board with EmWi:

I have placed a rectangle as Background - this works really well.
As soon as I am trying to Display a Text or a simple Widget the Lizard Boards jumps to the ewPanic function?

Could somebody give me an advice?

BR, Max

Answer 1

Hi Max,

please try to follow the single steps that are described in our Getting Started with STM32F469-LIZARD board. 

Does this work?

Can you try other examples that are provided in the Build Environment - do they work?

In case you get some EwPanic() - there should be some error message in advance. Please check the console output and let us know the error code.

Best regards,

Manfred.

Hello Manfred.

I followed all the steps. As soon as I am adding something else than a Rectangle the Board shows a black screen with its backlight.
I think somehow the STM32CubeIDE Project ist not working correctly.

The .hex files of the examples work really well. All the other examples which are generated in EmWi and imported in the STM32CubeIDE Project are not working.

Hi Max,

just to recap the issue:

The MasterDemo (which is provided as hex file) is working fine, correct?

What about the HelloWorld example? Can you try with GCC (via StartGccBuildEnvironment.bat). Does this work?

Does it work when you try to build it with STM32CubeIDE?

Best regards,

Manfred.

Hello Manfred.

1. Master Demo --> Working

2. Compiled with GCC via StartGccBuildEnvironment.bat --> NOT Working

3. Compiled with STM32CubeIDE --> Not Working.

Hello Max,

o.k.  so we should first figure out why the HelloWorld application is not working before trying to make your own GUI application.

Some more questions:

1. Did you adapt the display configuration according to your display?

2. Is there any error message reported during the download of the application?

3. Do you have a serial connection to the target, so that we can receive any error message from the target? Please check the console output and let us know the error code.

Best regards,

Manfred.

Hello Max,

I assume that the external flash is not programmed correctly.

Can you try to build the application with gcc/make?

Alternatively, you can try to disable the external flash by setting EW_USE_EXTERNAL_FLASH=0 within the file ewconfig.h. Then you are using only the internal flash memory. Does it work with this setting?

Best regards,

Manfred.
