MC9S12DP256B - Serial Bootloader - AN2153

Started by Kai Schneider August 18, 2004
Hello,

I am searching for a serial Bootloader for the MC9S12DP256B. On the
Freescale website I found the AN2153. (Serial Bootloader for Reprogramming)
Has somebody of you implemented this Bootloader with the Code Warrior? Does
it work?

Does somebody know an <http://dict.leo.org/?p=2Ib6..&search=alternative>
alternative <http://dict.leo.org/?p=2Ib6..&search=solution> solution, for
example in C?
Thanks for your answers!

Mit freundlichen Gren / Kind regards

no, because it has some disadvantages, see my mail dated 2004-08-11.

Why not? Although it contains some strange code portions, e.g. the
complicated "switch to RAM" which I don't think to be necessary. The
interrupt driven TX routine is also unnecessary.

If you have CW, it should be simple to try out.

I asked the same 2004-08-11, and got no satisfying reply. So I
started to roll my own, with smaller file format (base64 instead of
Motorola hex), no need for handshake and likely encryption.
