Download apps without BDM

Loris83 — Mon, 23 Nov 2009 22:20:49 GMT

I'm using MC1321x EVK.

I don't have a BDM.

Is possible uploading apps without using BDM?

I've read many discussions like this:

but nothing certain.

Someone could help me?

Hello and welcome to the fora, Loris.

Yes you can use a bootloader but you need to be able to programme the bootloader code in to your device first. For this you will need a BDM. The bootloader is some code that will remain within the device and talk to your computer over a serial port. It recieves and programmes your code and erases your code when required but does not erase itself.

The main problem is the Catch-22 in the first place.

So I need a BDM to work with this kit.

Thanks
