What is the difference between eCos and redboot?

Hi,

I am monica from germany. I have a newbie query.

what is the difference between eCos and redboot?

The documentation means redboot as a bootstrap environment.

But how can ecos run without redboot bootstrap?

Can anybody throw some light on the issue and give me some pointers like which documentation i should go through?

Thanks a lot, Monica Dsouza, Germany

Total. They're two tools serving almost completely different purposes.

Maybe it can't. That depends on the hardware. Some hardware may be able to boot eCos images kept in just the right storage, without the need for a boot utility. Other hardware needs redboot or something like to load the eCos from some place and run it.

To maybe put it into a more familiar context, think of redboot as your BIOS, and eCos as something like MS-DOS, to be loaded off the disk or floppy by the BIOS.

eCos is a full-featured RTOS kernel with BSD network stacks and all the usual RTOS features (mutexes, msg queues, semaphores, several different schedulers, time-slicing, etc.).

RedBoot is a bootloader. It's single-threaded and does all it's I/O using polling.

Yup. You can use RedBoot to boot any applications using any OS or executable image. It's currently used to boot Linux on a lot of embedded systems.

Use a different bootloader or just burn the eCos application into flash and run it from there.
