mc9s08dz128 bootloader

[martinlockner]

I am using the mc9s08dz and need to implement a bootloader. My problem is that I need to set up an external device before I can actually have the bootloader communicate with the Master PC software (send and look for an ACK). I would like to have the bootloader start and then exit to my main program and then after the external device is set up call the bootloader again from my application (from a menu selection). Any suggestions?

I would suggest refer to AN2295.

this document is available at:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=S08D&nodeId=01624684491437EDDD&fpsp=1...

and you can also download the associated file AN2295SW which is in fact the bootloader you can use in MC9S08DZ.

hope it helps!

Yong Li,

Maybe you can help me. I am trying to find out how to assemble the bootloader asm file in the S08DZ128/sources folder. I need to modify the asm file for my application and need to generate a S19 file. I can’t seem to find the appropriate application to do this.

Thanks in advance,
