    CoolRunner Rev C. To Obtain CPU Key From Jasper Dash 15574

    Using CoolRunner Rev C. to obtain CPU key from SB Jasper that is on dash 15574. Remember you need to wire the CoolRunner for RGH2.0 that means using the E & F points and discarding the point A. Used standard Phat wiring for Post_Out, E & F points just cut the green wire from a Phat wiring to the shortest distance possible as for CPU_RST I've used a 50cm blue wire from a Slim pack. Run the CPU_RST wire above the board & around the heat sinks before routing back to the CoolRunner.

    - Remove the JP point
    - Flash CoolRunner with TX_RGH2_B.xsvf
    - Write the RGX_Jasper.ecc file to the NAND (make sure you're already got valid NAND dumps to restore your NAND after obtaining your CPU key).
    - Wait & be patient, should take approx 3 mins to get xell.


    Edit: If you bridge the CAP and flash the TX_RGH2_A.xsvf to the Coolrunner you can see xell booting in times between 30 seconds & 1 minute. The only thing left to adjust is the length of the CPU_RST wire which will affect the boot times.

    Edit 2: If you leave the CAP open and flash the TX_RGH2_A.xsvf to the Coolrunner you can see xell booting in times between 10 seconds & 30 seconds. The only thing left to adjust is the length of the CPU_RST wire which will affect the boot times.

    Just for the record for improved RGH2.0 boot success rate and speed remove the C8 resistor from the Rev C (thanks to Dgenx for this tip).
