Hi guys , been trying to bench read a med9.1.1 it's been wired up correctly according the the attached picture , using and adapter we have checked the circuit in and out and all seams well , using pogo pins that are touching the pads correctly. Tried several drivers in the fg tech software the mpc 55x/56x times out , the jtag mpc55x driver works with out the external power being applied and gets to 36 percent and times out, but if the external power is applied then it won't connect at all. Has anyone tried using this tool for bdm mode before ?

I've used bdm100 for this task. I will try and use galleto to bench mode it with a known good ecu. Tomorrow of course.

Try powering the ECU directly via the pins at the bottom. Ensure +ve and -ve are connected before connecting the galletto physically to the ECU.

You can easily burn a med9.1 bdm port with bad connections so be carefull.It is always good to use a spring probe in a stable bdm frame.

Thanks guys for the input appreciate taking the time out to reply . I believe the clone tools the issue waiting on a bdm 100 tool now

I've ran into a known good ecu that wasn't readable by bdm100. Just a heads up.

I am using a 13,8V Power Supply which is causing alot of problems.
I endet up using LM2596 to play with the voltage.

Dont know if clone related or problem in general. :'(

When bdm writing med9 i sometimes need 3 attempts to reach the 100%.

What voltage at the spring-loaded pins is ideal?

Depends on your definition of "known good". If I couldn't read via BDM, I'd say it's not good. There's absolutely nothing you can do, short of physically tampering, to disable BDM reading/writing.

My Maplin 12V PSU puts out a steady 12.5V and I've yet to encounter an issue read or writing. To get me out of a hole, I've even used a 10V PSU from an old cordless phone that registered 10.2V. Stability is the key.
