Bug on Cubemx - Touchgfx

[SMour.1]

I am using the latest Touchgfx+Cubemx and code generation from within CubeMx fails without notification. The process completes but the generated file /TouchGFX/target/generated/TouchGFXGeneratedHAL.cpp

contains some weird java error logs

Hot to work around that ?

The logs , focus on line 129 and after:

I think the new setting about FMC (which is undocumented on TouchGFX site is the one causing the problem

[Karim BEN BELGACEM]

FMC Display interface was not tested for H7 platforms.

Default FMC base address was set to 0x60000000 (F4/L4) and the computation done by CubeMX is not be able to parse big Integer (unsigned intor long).

We're currently looking to that and will fix it for the next release.

What I'll suggest for you now is to keep the default value and overwrite it after code generation (change 0x6... by 0xc..)

Please confirm also if the 0xC0000000 is the correct FMC base Address for H7 or maybe you had confused it with SDRAM address.

[RSt.1]

Hello!

This bug is present when creating a project for the F417 when activating the parallel RGB (FMC) mode. How is it possible to get around it?

Tested in TouchGFX 4.17 and 4.18. According to the instructions:

Thank you.

Sooooo, two years is ST unable to fix this problem? Are you kidding right?
