Can you please elaborate on that?
What kind of serial adapter did you start fro?
Something like this: PL2303HX USB to TTL Converter Module 5V & 3.3V Output, Onesanya brand
or this: USB To RS232 TTL PL2303HX Auto Converter Module Converter Adapter For arduino, no brand
Did you feed the VDD_325 pin with an external power source? Or from the Kindle itself (where I can find 1.8V on the kindle?) Or do another modification?
