@mverch67 this was in the design repo cross platform project, I converted it to a firmware issue

Funny, we were just discussing this on the discord yesterday. I didn't even realize an issue had been opened on the topic.

I came across this which might be useful as a starting point: https://github.com/mryndzionek/esp32_offline_osm/tree/main

I think the most difficult part (from my perspective anyway) will be getting the SD card functioning. I've tried in the past and had issues with the SPI locking.

perhaps the most valuable feature of the t-deck. would love to see this happen in some form of OSM

I'd like to be able to log position data locally to a TRACKER device. SD card support is clearly a necessary first step.

This YouTube video shows how the problem was solved for a LilyGo device: https://www.youtube.com/watch?v=hLCFNR3jp8Y

I would love to see this feature as well.

Hi, I'm working in a project with Offline OSM maps (PNG tiles stored in SD card) as well (under development) vector maps.

My programming skills are fairly simple, and it's a personal hobby project. Perhaps something from it could be useful to you."
