Using USBDM to extract HEX file hsc08

[fawad89]

Hello,

I was recently asked to reverse engineer an inverter card, that uses mc9s08ac48 controller by NXP, i got USBDM programmer, is there anyway i can extract the HEX file from a current microcontroller and use it.

how to use  memorydump program to read the flash and produce a Motorola SREC file  by USBDM programmer?

how to use it   to read flash?  Have you provided any documentation

Firstly - Please don't add to existing threads unless you are responding to the thread - Start a new one please.

This program was written in response to a particular request and there is no info apart from what the program provides in pop-up help for the fields.

You need to be familiar with the architecture to understand the options.

You need to know the target memory map and what areas you are interested in to determine the memory ranges to read.  If the target is paged this is additional info. needed.

It's pretty low-level - what do you need help with?

i want to read back flash data of MC9S08JM60,i can use USBDM Memory Dump to finish my job?

how to set the value of star, end and the width?

the flash address of  MC9S08JM60 is 0x1960----0xFFFF

If the chip has security enabled then it is not possible to read the flash.

Otherwise, the memorydump program should be able to read the flash and produce a Motorola SREC file.

bye
