First do you have another HC to try?
?
Have you set Serial ports to ?? Sometimes serial ports are different baud rates (for GPS etc), the HC needs this baud. .??
?
Its possible the microSD cars have been swapped over....you can read them on a computer to see their file contents.?? If they look ok you can still try rebuilding the appropriate cards files but do it one at a time to see results (but format the cards first).?? The MU SD card does write to the HC ARM and card.??
?
If you are concerned....you can redo the
SD cards with the correct files and reinserting them to write to the HC (of MU) by downloading combined.zip file.....and rebuilding both cards.?? Of course doing them one at a time or letting the MU update the HC.? Then inserting them....letting the unit to update itself directly.?? But just as easy to just do the MU card and it will write to the HC.
?
Lastly...if you have disassembled the HC......be very careful reassembling the RJ port "case end Plate" of the HC!?? It is cut lower on one side and you can make it fit both ways (aka upside down).?? But if you do this (put it in upside down) the port RJ fingers will be pressed or forced up away from contact with the cable pins.?? Only close inspection shows this.?? this drops out coms to the HC....all you ever see...if it gets power and GND....is the splash screen.?? Now you would think that this forces away all the contact fingers....no I did it it just forced the rxd pin away, it still have pwr (5V) and GND....just contacting (intermittently).

Get back
