If your on mac the downloaded firmwares can be found by right clicking M5Burner selecting "Show Package contents" then clicking through to Contents > Resources > Packages > fw then you will find the firmware files in each respective core folders. I don't have a linux machine handy at the moment but perhaps the folder structure is similar

RE: M5Paper - operational
@kevindtimm if you look at the first line comment of most of the arduino examples, they will require some font file or jpg file included in the example folder, to be transferred to the SD card

RE: M5Paper - operational
hi @kevindtimm which SD card brand did you use, did you make sure to format it to fat32 and put the necessary files in the root of the sd card

RE: M5Paper load font
please refer to my reply on your other post, has this been replicated 3 times now?

RE: M5Paper load font from sdcard
Hi @Powersoft please don't double post, and refer to my reply on your other post

RE: M5Paper load font message "FT_Stream_Open: opened `/GenSenRounded-R.ttf' but zero-sized"
Hey @Powersoft this example requires you to put the GenSenRounded-R.ttf font file found in the M5EPD_TTF example folder in the root of an sd card or load it into spiffs with the "ESP32 Sketch Data Upload" plugin, did you do that?

RE: M5Paper SD Card Issues
I haven't had any problems with SD cards in the M5Paper, I have been using Sandisk Ultra cards 8-16gb. I think the max sd size for esp32 should be 32gb, make sure to format to fat32, and make sure the font or jpg file are in the root of the device. Perhaps it is also possible to use larger exfat formatted cards as stated in this forum post https://www.esp32.com/viewtopic.php?t=14492 I haven't tried this myself.

RE: Pure Micro Python without Ui-Flow on my M5Stack core2
Hi @Wolli01 as for the M5 Basic you can refer to my video https://www.youtube.com/watch?v=GPRNUCBTVy4 As for M5Core2 I cant tell you as I haven't got round to testing pure micropython on this device. If the screen is not displaying anything are you sure you have a micropython driver in the flash and have initialized the screen in your code?

RE: Pure Micro Python without Ui-Flow on my M5Stack core2
Hey @Wolli01 unfortunately this option isn't available right now but you can take a look into it yourself if you have the know how, the screen of m5core2 uses littlevgl library which has been ported to micropython https://github.com/lvgl/lv_binding_micropython for the micropython firmware you can just go to micropython.org and download one of the firmwares for generic esp32. As for the various modules there has never been an official github with these available, I have one for mpu6886 and axp on my personal github which should work though. I'm afraid this is going to be like a jigsaw puzzle, piecing various resources together to create the firmware you want
