Can not get the display to light up on a m5stck core 2 v1.1

[Micaelaman]

Hello,

I try to get the display to work on a Core2 but so far it stays black. I have follow the instructions here:
https://github.com/stefanthoss/esphome-axp2101
and this
https://gist.github.com/SmartyVan/6f9f6c4c5633caa1c91a6c8e067f44ff#tilty-esphome-configuration

Everything else works, but the dusplay wont light up.

I'm out of ideas. has anyone else got it to work?
