CubeMX 6.15.0 unnecessarily configures R1 pin in LTDC peripheral when using RGB666 Display

[Craig_Robertson]

For the STM32H743IIKx micro, CubeMX 6.15.0 unnecessarily creates a configuration for the R1 pin when creating an LTDC peripheral when using the RGB666 Display Type.

This should not be configured. The required R* pins for this Display Type are R2-R7, as per G2-G7 and B2-B7.

This did not occur in previous CubeMX versions, including 6.14.1.

This bug means that it is not possible to upgrade to this version of CubeMX with an existing project that already uses the pin(s) required for LTDC_R1.

Hello @Craig_Robertson ,

 

It is a regression on the STM32CubeMX V6.15.0.

This is a known Issue, and an internal Ticket was submitted to the Development Team 

(Internal Ticket Number: 215387).

I will keep you up to date when the problem is solved.

 

Best Regards.

Thanks very much for the quick reply.

Hello,

Any news on this ?

The fix I am using now is to modify the generated source code. This is not satisfying.

Note that when migrating a project to 6.15.0, LTDC configuration is removed without user notification because there is no pin available for LTDC_R1.
