I'm using TouchGFX version 4.24.1 with external flash memory mapping at address 0x90000000.
When using the original image, there are no issues. However, when using the compressed RGB565 function, a tearing effect appears on the LCD screen. If I disable 'SCB_EnableDCache()', the issue is resolved.
Therefore, I believe that 'TouchGFXGeneratedHal::InvalidateCache()' is not properly invalidating the decompression buffer
- Is there a solution for this?
- If I disable 'SCB_EnableDCache()', will it have a significant impact on display performance?"
