F746G-DISC does not work with TouchGfx 4.22.1

[hbZhao]

Hello,

I just bought a STM32F746G-DISCO from Mouser (STM32F746G-DISCO STMicroelectronics | Mouser).

After it arrived, the LCD and touch screen were working well. However, after I downloaded the demo project (STM32F746G-DISCO Control LED from GUI v3.0.6) in the TouchGfx 4.22.1, there is not anything displayed. Also I removed the TouchGfx and installed a version, 4.21.3, but there is not any luck.

The board is the blue one. The label on the front is 'STM32F746G-DISCO DK32F746G$CU2', and the label on the back is 'MB1191-F746-C01 / C222103562'.

I found in the previous discussions, the hardware has been changed from version B to version C.

• QSPI Micron N25Q128A13EF840F changed in MT25QL128ABA1EW9-0SIT (reached B-05)
• LCD Rocktech RK043FN48H-CT672B changed in KUNJIAN HT043C (reached B-05)
• MEMS ST MP34DT01TR-M changed in ST IMP34DT05TR (reached C-01)
• Oscillator NDK NZ2520SB 25MHz END4869B changed in NDK NZ2520SH 25MHz END4869C (reached C-01)
• Oscillator NDK NZ2520SB 24MHz END4869B changed in NDK NZ2520SH 24MHz END4869D (reached C-01)
• USB protection ST USBULC6-2F3 changed in ON Semiconductor ESD7383NCTBG (reached C-01)

May I know how to generate a WORKIING project with TouchGFX? Thanks.

Hello @hbZhao ,

Sorry for the late response, 
I tried the board specific demo with a MB1191-F746-C01 (I think it's a bit older than the one you have but shouldn't be any drastic changes), and it works correctly. 
Could you please check if you can run other demos (non-board specific ones) on your board? By going in the Demos section and selecting F746 as your Board Setup.

Thank you

Hello Mohammad MORADI，

Thanks for your feedback. This issue has been fixed after I downgraded the development tools.

What version did you have to downgrade to? I am currently having this problem.
