THX for the pictures. Curiously, this screen had not been reviewed in teensy 3.6 with the new SdFat beta library, I only experienced in teensy 4. The data sheet on the RVT50UQFNWC0x screen indicates a maximum working frequency of 30 MHz on the SPI bus. In the teensy 4 this screen can reach up to 47 MHz, in the teensy 3.6 it only reaches up to 29 MHz. I have modified the library to take this condition into account. Download the GD23ZUTX library and try it again. SetSPISpeed = 29000000
SPI.beginTransaction(SPISettings(SetSPISpeed, MSBFIRST, SPI_MODE0)); 20-pin header Teensy 3.6 + Riverdi RVT50UQFNWC00 If you notice any kind of instability on the touch panel or on the screen, I recommend installing a 10K pull-up resistor on the MISO, MOSI and SCK lines. Pull-up on MISO, MISO and SCK lines

I have been the last week so I was able to try it again. That updated library works flawlessly. Once I updated the library, I immediately went through all of the example and it runs good. The only example that didn't work was the video example. I got a coprocessor error once I uploaded the code. What do I need to know to work with a video. I would like to get video to work if it is a possibly.

It seems a failure in the micro SD. 1) Format the card in windows, using the option "restore defaults". 2) Copy the files from the ToMicroSD folder to the card just formatted in the previous step. 3) Upload the example again to play video. To create custom videos, even with audio, it is best to use the EVE Asset Builder tool
