Can't get past this point. On Serial Monitor, I see:

Initializing Flash Memory...

Determining write/read start point...

Send 'y' to start read mode. Write mode will begin in 10 seconds...

Now initiating write mode.

Attempting to wake GPS module..

I GPS shield works, for just was using it for another tracker, The Cat Tracker. It of course uses an SD card shield. I substituted the SFI Flash shield. The 2 Includes I'm using are
#include "SoftwareSerial256.h"
#include <SPIMemory.h>
I tried 4800 for GPSBaud speed instead of 9600
The 4 boards are from top to bottom
Tiny Duruino

Please help

Hi- sorry about the problem! Can you test with the latest GPS code example at: and let me know if it initializes properly?

Hi Ben, I hope you are well.
As mentioned, I endured same issue, I thought.  What I learned is that the stack was working, but I thought not because the serial monitor doesn't show the data.  When I checked the SD card, there was data being written I wasn't aware of.

So, if you encounter the situation where it appears the data isn't flowing, check your SD card.

Than you!
Be safe.
