uCLinux on Connect ME - without JTAG

Hi together!

Does someone know how to flash uCLinux on a ME without JTAG ? - For the production models I’ve got I don’t know how to do this. Is there a special jumper config ?
When I hot-wire Pin 3 and 4 of P5 (MFGI to GROUND) on the Integration Kit board I get the diagnostic mode but this is not what I need (no access to POST area).

Any Ideas ?

Thanks a lot!
