access problems to target with USB P&E and MC9S12XDP512

[chris69]

Hi,

I was programming my MC9S12XDP512  with the P&E USB multilink and PROG12Z, it worked fine.

But this mornig, i did a mistake, i launched PROG12Z, i choose my alogrithm, and instead of click on "erase module", i clicked on "blank check module".

So i stoped the process in the middle of the operation, and i cliked on "erase module", but the operation began et never stoped. So i closed the soft, and now i can't connect my proceesor; each time i launch PROG12Z,  i have the message "Can't communicate with the target processor.Target processor may be  secure, unpowered or not properly connected".

Can anybody give me a hint how I can gain access to the target again?

Did you try to unsecure with P&E unsecure12 utility? You can download it from www.pemicro.com .

IO_DELAY_CNT setting is quite weird. Shouldn't it be 240/ oscilator frequency?

Thank you kef,

My problem was my processor was secure, I unsecure it with Codewarrior.

thak you again.
