Whats the plan

Many thriftstores have huge piles of these little linux devices with bad batteries and ancient maps.

Seeing that most of this stuff is actually open and usuable, refurbish them somewhat?

Useful stuff to know

  • The USB port for charging is also a OTG port (at least on OneXL)
  • If you have USBdata connected on powerup to a PC , the bootloader gives you full access to the internal flash (on models that have that) (ALSO IT WONT BOOT FURTHER WHILE USBdata IS STILL CONNECTED) (doesnt happen with just power)
  • Week rollover is a thing that might prevent GPS link? https://wiki.navit-project.org/index.php/TomTom#GPS_and_GPS_week_rollover
  • 'ttsystem' file on disk is kernel + initrd , opentom comes with a 'ttimgextract' tool , check opentom's README.md

Works?

beckershoff built some images and sent them by PM , these already gave me something working on the OneXL.

A bit later , buZz built this image ; https://space.nurdspace.nl/~buzz/buzz_tomtom_feb2022.tgz which MIGHT require a SD card for the rootfs.
