Hello,
I am facing the same issue and not able to display the images on to the M5 Paper. I have tried both canvas.drawPngFile(SPIFFS, "/smiley.png", 0, 0);
and canvas.drawJpgFile(SPIFFS, "/smiley.jpg", 0, 0); but no luck.
I already included #include "SPIFFS.h" and initialized SPIFF using M5.begin(true, true, true, true, false);. The png and jpg files are inside the data folder. SPIFFS.open("/smiley.png") is able to open the file however it is not printing any file content on the console.

I think it is required to format the SPIFFS for the first time, as mentioned here so I followed these steps but ESP32 Sketch data upload is not appearing in arduino 2.0.

However I am able to display the png image using canvas.drawPngUrl("http://imageUrl"); but it is taking more time and quite slow.

Could you please help me in understanding what I am doing wrong?

@ajb2k3 thanks so much for that insight. Do you have an implementation of HV write mode for the Paper display in a different platform (UIflow etc)? Don't worry if not, because it seems that existing shutdown() is able to retain images according to @felmue's example.
