Run OTP Boot Loader in SARAM

Yvon Carlsson
Intellectual 280 points


Hi all.

I am working with c2000 f2812 device.

The device I am working with could only be accessed through the SCI-B. By default it boots only from SCI-A (works well Spraaq2). I would like to overwrite bootlooader as per Spraaq3 document. The document olso suggests to try to run it from SARAM initially to be sure everything works.

The question is: How do I set up a .cmd file fort that?

I have checked the c2000 forum; found that some people did that no explanation how.

Thanks in advance,

Yvon.

    Yvon,

    You may find this wiki article helpful:

    You can also take a look at the linker command file for the boot ROM itself and move the loader section to RAM and remove sections that are not needed.
