Bootloader MC9S12DP256B - jcz - Oct 7 14:28:00 2005
I have a basic question : how can I upload/run bootloader on motorola
MC9S12DP256B (I am using CodeWarrior 5.5, BDM-MULTILINK)
I found some s-rec files (AN2546SW.zip) on freescale.com with doc's:
"HCS12 Load RAM and Execute Bootloader User Guide".
When I try uploading these s-rec (for 256) either I have memory errors
or it just doesn't work. If these files are not correct, where can I
find s-erc with a bootloader for MC9S12DP256B and how can I upload them ?
Do I need to put any jumpers on my board ?

It is the correct file. Use the SrecCVt to format it for banked S-record.

Yes the code checked PAD0 and PAD1 to see whether run your code or
bootloader.

I put jumpers on PAD00 and PAD01 on JP5.
I uploaded Dx256_L91N_2CAN.sx using True-Time & Real-Time Debugger
(file --> load application with erasing NV mem.).
I close True-Time & Real-Time Debugger.
I power cycle the motorola board.. and nothing happens.
What I am doing wrong ?
Could you please send me a s-rec file with the bootloader that
(possibly) you are using ?

Maybe because instead you need to use the Serial Monitor? Look for
AN2548, AN2548SW1 and AN2548SW2 at Freescale site.
You need to compile for your own Run/Load switch. Choose a port pin.
