RE: 5213 bootloader

Hi Pat:

 

Here are a couple of links that may help you:

If you haven't already done so, the first step is to get your code to copy
from Flash to RAM.  Then you can insert a small piece of code in the Flash
that can accept applications over the USB, Ethernet etc.  The trick is
either running it (the bootloader) entirely out of Flash or using a small
amount of RAM that is then overwritten once the application is installed.
Depending on the RTOS (if you are using one) this can be somewhat
problematic.  But check out the above links.

Subject: [ColdFire] 5213 bootloader

 

All,

 

I need to create a bootloader for a mcf5213 application. I hope to have it
reside on a sector of the onboard flash. Can anyone point me in the right
direction to sample code and documentation?

 

Thanks in advance,

Pat
