I found BSP for few of M5Stack boards in espressif component registry like

https://components.espressif.com/components/espressif/m5stack_core_s3
https://components.espressif.com/components/espressif/m5stack_core_2

but couldn't find the same for two of the boards I own.

what would you recommend? I am looking to use esp idf qemu for quicker feedback during development.

Thank you, is there a github repo for samples for papers3? not all official images in m5 burner for s3 works. I'm looking for api that are applicable so i can learn to program papers3

There isn't a lot of program available for PaperS3, I couldn't find source for "PaperS3 Factory Test"
