Porting to the customized Hardrware

Question

Hello EW-team,

I was working with STM32F746G DISCO board running a GUI project  created with EMbedded Wizard studio. I used STMPlatformpackage as mentioned in the documentation and able to run successfully on it. Also created STM32CubeIDE project and able to load on DISCO board

Now , the customized hardware has STM32F746ZE MicroController : 1MB Flash , 320KB RAM , with QSPI flash (128Mb) , SDRAM (128Mb) , 480x272 size LCD with RGB565 color format used. Hence I have used above DISCO board platform package as Template.

The customized hardware is already up and running with GUI and Application code (without Graphic framework). Here, I am trying to evaluate EW framework to create same screens. 

The change made to the platform package STM32F746G DISCO :

• MPU_Config() : updated (based on the existing working code )

Also, there is no boatloader preloaded in the controller. 

 

 

But I am facing issue below issue added from Console output  : Failed to initialize RAMCode. Kindly suggest a solution

Hello,

according to the provided error logs, it seems to me that you have some problems with the external flash loader.

Please try first to locate all Embedded Wizard resources into the internal Flash instead of the QSPI flash. You can achieve that by setting EXTERNAL_FLASH to 0 within the makefile. If you are using other toolchains you have to disable following macros within the project options:

EW_BITMAP_PIXEL_SECTION_NAME
EW_FONT_PIXEL_SECTION_NAME
EW_USE_EXTERNAL_FLASH

Then rebuild the project - there should be no content in address range above 0x90000000.

Does it work?

Best regards,

Manfred.

Hi Manfred,

I tried the above steps in the project options

                                    <listOptionValue builtIn="false" value="EW_USE_EXTERNAL_FLASH=0"/>
                                    <listOptionValue builtIn="false" value="EW_BITMAP_PIXEL_SECTION_NAME=0"/>
                                    <listOptionValue builtIn="false" value="EW_FONT_PIXEL_SECTION_NAME=0"/>

Now , there is no content in the address range 0x90000000. 

However the issue still exisits . Console output is below

Code execution moves to void HardFault_Handler(void) function

Hello,

to be honest, for me it is not clear what the problem is....

Is the download of the application possible and successful? There are still errors reported from the J-Link. This should be solved first.

Are you able to run a simple C application, e.g. a main() with a few printf()? Does this work?

If downloading of the Embedded Wizard GUI application is working - do you have any outputs in the console window (via serial interface)?

Best regards,

Manfred.

Hello,

please try to rename EW_BITMAP_PIXEL_SECTION_NAME and EW_FONT_PIXEL_SECTION_NAME instead of assigning 0 (e. g. _EW_BITMAP_PIXEL_SECTION_NAME and _EW_FONT_PIXEL_SECTION_NAME)

Regards,
Martin
