Embedded Bootloader vs. Codewarrior

Diego — Fri, 17 Mar 2006 07:21:10 GMT

Hello

I am working with sard 13192, hcs08gt60.
I was programming the processor using the BDM. But now that I want to compile a bigger program, like the wireless uart, I am getting an error using codewarrior, the size of the user program is >1024 bytes, license restriction.

I am confused.

If I use embedded bootloader I can download the wireless_uart example without problem of size?

But if I burned the flash I erased the embedded bootloader in the board?

Thanks for your help.

Hi:

Indeed: if you used the BDM, you erased the bootloader.

You need to get an evaluation license (valid for 30 days) to be able to compile bigger programs.

Probably you were using the wireless example hex file (already compiled), so your bottloader didn't have any problem downloading it.

Hi Diego,

Just been through this in the last week.

If youv'e got a BDM tool don't fiddle around with embedded bootloaders, upgrade your CW to Special Edition. I had to request the licence file by email as I got no registration code in my kit. The kit comes with 3.1 on CD and the available code (SMAC4.1a etc) is designed for 3.1. They sent me a licence file that looked like it was for V5.0 but it worked. Indeed when I checked with the licence file in my downloaded version 5.0SE it is the same.

BTW, you can use it with CW5.0 but you have to wade through all the warnings and errors etc, using 3.1 they just work straight up.

Hi Diego,

If you register your CW, you will obtain for free16Ko. I don't know if your application can match this size, but between 1Ko and 16Ko...
