Hello,

can you please check the board revision that you are using and let me know?

I assume you have one of the latest board revision of the STM32F769 Discovery board with changed hardware components (due to chip shortage). We are working on that topic.

Best regards,

Manfred.

I think it is.

Let me know if there are any changes.

Hi,

i think i might have the same problem. I have a STM32F469I-DISCO  MB1189B board and after make install the screen stays black, during the transfer everything looks good and it finishes with "success", but screen stays black.

Full board ident: MB1189-F469NIH6-B08A220900227

What should i do? I can't find any troubleshooting or so. Could it also be a hardware problem?

Thanks,

Philipp

Hi Philipp,

thanks for your report! Meanwhile we have done further investigations with the latest board revisions (STM32 boards with DSI display). The initialization of the DSI display is now adapted to support both, the old and the new display types (LCD FRIDA FRD397B25009-D-CTK and FRIDA FRD400B25025-A-CTK).

Please update the Build Environment (version 12.00.00.01) and try once more. The following packages are updated:

Please let us know if it works.

Best regards,

Manfred.

Hi Manfred,

thanks for the fast reply! But sadly it didn't work out either with the new version, screen stays black.

Hi Philipp,

ok - this issue is not related to the DSI display - now we have some troubles with the touch device on STM32F469 Discovery board.

Let me try to organize a board with the latest hardware revision to check what is going on. I will keep you informed.

Additional remark: I just noticed that the Build Environment for STM32F469 Discovery only supports MB1189 B-01 and MB1189 B-02:

Anyhow, I will try to get a MB1189 B-08 and see what is going wrong.

Best regards,
Manfred.

Hi Philipp,

good news: Meanwhile I got a revision C board of the STM32F469 Discovery board and I could reproduce the reported issue.

Please update the Build Environment (version 12.00.00.02) and try once more. The following packages are updated:

Please let us know if it works.

Best regards,
