The FIF0 is 4k so you might be over running the buffer. Make sure that your display list commands do not go over 4k

Simple weather station application for an ESP using the WEMOS D1 Mini and a Matrix Orbital EVE3 4.3" SPI Display.

The display used, EVE3-43G is an oversized Capacitive touch 4.3" IPS TFT for easy mounting and clean design. The EVE3 uses the BT815 and BT816 as the graphics engine and features 32Mb on-board memory.

If you let me know what screen resolution you are using I can query the dev team for information on where the points would be located on the screen.

We are currently testing the 4.3" screen, with a resolution of 480x272. We will probably migrate to a 7" screen for a resolution of 800x480.

Hello T.Pierret,

Please contact me if we can help you with the hardware.

Thank you!

You might find this helpful, we have an example of CMD_FLASHUPDATE with 4k blocks that are automatically erased and written using GRAM as scratch space.

Look for the function "FileTransfer2Flash" in process.c
