Project Info

Planned experiments with this SoC. No datasheet is available ("leaflet" only see [1]) but some schematics and reverse engeneering info are available. This is very difficult task, it is BGA 676 contacts chip.
At the moment I only made theoretical analysis of the problem.
First step will be testing of desoldered STI7111's because I dont know if it is OK.
