MC9S12XS128 Verify Error

[spiros]

Hello pgo i have a small problem with an s12xs128 mcu,i successfully reflash the rom file that i have in linear address $7E0000 but when i try to verify fail and get this message " that buffer is not agreed with the content".

What do you think is the problem and i can't verify the file that aleready is inside?

Mcu is not secured.

Hi Spiros,

I have just retested with a MC9S12XS128 and it passed the tests I tried.

Could you provide the image you are trying to program so that I can test further?

Also:

• how was the image file produced?
• What BDM hardware?
• What Operating system

Thanks.

I provide you the file that i have the problem.

The bdm hardware is the JM version with firmware 4.10.6 but the same problem occurs with the JB version.

The operating system is windows xp.

Thank you

Hi Spiros,

The USBDM programmer uses two different methods to verify the image programmed.  A more complicated method used during programming and a simpler read-back used for the "Verify" function.  Unfortunately the second method doesn't handle linear addresses correctly.

I have attached a modified programming file that uses the 1st method at both times so that the separate verify will correctly validate the flash contents.

Note: It was the verify which was in error.  The programming and programming verify was correct.

I will have to consider the appropriate long-term approach.

bye

Hello pgo

Yes the programming-verify works great only the verify was the problem.

Thank you for the quick fix.
