Hi,
I am trying to flash this ic with 9S12XDT512 Freescale_9S12XDT512_1x16x256k_512k_Linear_16k_page.12p however it wait for ever.. Is it lock ?
Greetings,
1) Which PEmicro hardware are you using and its revision? Check the back sticker.
2) Where is it waiting forever? Loading algorithm? Erase? Program? Which step?
3) Did this work in the past, or is this your first attempt? Is this chip fresh, or has it been programmed in the past?

Hi,
1) Multilink FX been know working with prog12z. The firmware (of the multilink fx) was able to update when connecting to the device
2) loading algo rithm is fine, it stall the the next step when I upload to the pc to copy original firmware..
3) The chips is working in the original box..
Greetings,
If you are able to load the algorithm, then the chip is not locked. For HC12, if you secure the chip, you would not be able to enter debug without doing a mass erase.
If you use the command "show module" are you able to see the memory contents?
Do you know if the board has any external watchdog? It could be interrupting communication to the chip and causing it to lose contact.
Did you make any changes recently that would cause the Multilink FX to stop working properly? New board? New software?

Ok,
I tried another device, with the same computer and multilink fx, and it's working..
Now Show Module doesnt work neither on the first device..
The external watchdog would be connected to the power or a special pin ?
Greetings,
It would be connected to the RESET line.
When you said it is working on a different device, do you mean another board of the same product? Or completely different HC12 device or different board design?
At least this gives me confidence that the software and multilink is working properly and there is an issue with this specific board.

Yes, I different design, the programming port has 2 extra pin I guest i will have to analyse those ..
Thx
Greetings,
Any update on this?
