HC08QC8 programming issue with P&E Multilink

TonyLin — Wed, 04 Apr 2007 16:24:47 GMT

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!

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.

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.
