Hello,i am trying to implement Openamp to in a project with touchgfx. In the beginning i started with openamp and it worked. M7 was the master, M4 the slave and i had a working implementation. It turned out that encoders etc are better handleled on t...

Hello,i am working on a board that is redrawn from the H745I-Disco which originally has the FT5336 as touch controller. My Display has the FT5426. On an earlier board that recreated the F746-Disco (which also has the FT5336) i noticed that the FT542...

Hi,i have troubles finding the external loader for the H745I-Disco schematic. I have to admit that i drew my own board without trying it on the disco board first.The schematic says that for two Quadspi flash ICs the MT25QL512A should be used. I have ...

Hello,I made a custom f746 board like it is done on the discovery board. I have only implemented SDRAM and QuadSPIFlash. I can program the mcu without any problems. The display flickers heavily https://youtube.com/shorts/pYuCkyMqsgM?si=iGS41lJvxs_Cg...

What I found is that it starts with this function, MX_OPENAMP_Init(...). The last function call is metal_bus_register(...), which gets a struct object named metal_generic_bus. The objects address can be read in the main and is valid, but the name is ...

Hi Gaetan,thank you very much for your reply. You summarized my problem correctly. The thing that didnt catch my eye right away was that x and y coordinates where swapped. As soon as i assigned x to y and y to x it started working. The difference bet...

Thanks for your reply! The project was generated with touchGFX and ran on the F746 Discovery board. I redrew the MCU, SDRAM and QUAD SPI Flash so it should work the same. I had no problems on the Discovery board.There is no problem if only one or two...
