STM32F469 Discovery looking for working example CubeMX+TouchGFX project

No, I didn't modify anything. I bought a discovery and wanted - and now finally working on - making a device with display.

As for documentation - I've found it all, but some bits and pieces of info are missing there - for example HSYNC/VSYNC values are not available even in OTM8009A datasheet (there are porches; and there are only parameters for 480x800, but not for 800x400, among other resolutions it supports; Datasheet has landscape and portrait resolutions independently, switching values between horizontal and vertical didn't work - there is nothing I didn't try I think), which you have to find pirated in the internet (and there are two versions of it - one's half-finished).

I'm not the dumbest guy in the area (sure hope so) and I pick things up quickly, and I'm not afraid of stuff I don't know as long as there is stuff to read/watch, rarely ask. I haven't had a single STM32 project at all (blue pill on arduino ide doesn't count of course). I did play a little with PIC microcontrollers - set up I2C by manipulating registers directly. I became proud of it but decided I want to stay sane. And I wanted some more up-to-date architecture. So I switched to STM32. I think I had no problem with basic STM32 operation from day 1 - GPIO, I2C stuff. It's the display part that was difficult. I've watched many lectures on how stuff works, everything made sense for me. It was a lot of info, but it wasn't all difficult in principle. It's just much.

Most examples - all of them actually - work with 746 Disco. Literally EVERY tutorial has 746. I searched in several languages, and it's only 746 everywhere. And I already had 469 because I needed that extra resolution. I wanted to make it show a picture that I'd expect so that I could start working on PCB. I won't start it until I know I can actually make it work in software. So my adventures began.

Following 746 tutorials/examples, I set up hardware in cube, LTDC, DMA2D, FMC, added DSI, FreeRTOS, then I added TouchGFX through Cube. With 746, I had working TouchGFX in 2 hours. On 469...it didn't work. Still don't know why exactly, sometimes I even had hardware faults when debugging. Of course I kept in mind I have another MCU and hardware, I accounted for it. Tried with BSP drivers (corresponding to MCU/Disco board of course) - SDRAM initiated OK, the display - various, but incorrect results. The best I got was working TouchGFX with smth like 10FPS with Slo-Mo - 1s animation takes like 4s or something. But hey, at least there were no artifacts. Can't say much more, it's been 2 months of almost DAILY attempts - with a week sanity breaks. I tried everything I could imagine and even some things I could not imagine.

After hours of lectures, examples, questions, kilometers of forum threads, I accidentally found out I can actually start the project from TouchGFX, and I can actually have some working code there that initializes everything. So I eventually arrived at the solution yesterday. Integrating TouchGFX project into Cube isn't easy and seamless tho, which is a shame, but I did it eventually. Now I can develop further and I can read the "correct" working code.
