Please delete thread. Figured out issue.

I notice now that if I try use a clock divider less than 4 with PSRAM it fails to provide an output, but can use a clock divider of up down to 2 with the SRAM when using the LCD peripheral. Any ideas why? I have an S3 with Octal SPIRAM. // LCD_CAM_LCD_CLK_SEL Select LCD module source clock. 0: clock...

Thanks for this. Got it to work after calling this function.

Could I write to the PSRAM using DMA from SRAM?

Would that get around the issue of trying to change bytes directly from the PSRAM malloc?

Hi. I have created a sketch that allocates memory and then links up DMA descriptors so that it loops forever. When I try to do this using PSRAM as the DMA buffer, I get garbage output. Refer to live example here: https://github.com/mrfaptastic/esp32s3-hub75-psram Any ideas? Is this some cache issue ...
