Re: [ECOS] eCos ROM startup from RedBoot

[Ilija Kocho <ilijak@siva.com.mk>]

Hello Pierre-Jean

Sorry for delayed response but it took some time.

It seem that it works.
The startup type could be something like this:

You may also need a Flash driver, it's on a way:

Note: Flashing is critical operation, it may lock your Kinetis flash for
good, no protection yet. Usage is on your own responsibility.

Regards

Ilija
