HC08QC8 programming issue with P&E Multilink

[TonyLin]

Hi, I am using a P&E Multilink to program code into QC8 chip. However, I always encounter this problem during flashing procedure.

"Trying Security $FFFFFFFFFFFFFFFF Access Denied.

   (68HC08 Device responded properly, but ROM is secure.)

ERROR 48 during script!"

It is not caused by my program, because I use CodeWarrior to generate a fresh new QC8 code to try.

But if I only change the device setting to QC4 or QY4, the flashing works.

Is there any compatibity issue between Multilink and QC8? Thanks!

Hello,

You need to make sure you have a Power On Reset (power cut and put back on).

And you can ignore security to erase the flash.

Hi Tony,

Given that the only real difference between a QC4 and a QC8 is the amount of flash and that the QC4 setting works, I would assume there is a problem with the 08P file for the QC8. The only problem with using a QC4 file on a QC8 should be that you are limited to the top half of the FLASH.

You could try hunting down a more up to date version of the programming algorithm on www.pemicro.com

or putting this question direct to them on their forum there.
