I'm implementing TouchGFX on a Custom Board using the same circuit as the STM32H735G-DK for the external memories. I detected that the RAM DQS Pin(OCSPI2_DQS) is always low and does not work. The display is always grey as the framebuffer is not written properly.
The display is working well, I tested it by using an internal framebuffer.
The hardware is all correct in terms of the circuit. I checked all the lines with an appropriate oscilloscope and all are working fine except for the DQS on the RAM. All the memory components are the same as the STM32H735G-DK board as well as the firmware configuration.
