RE: [ECOS] Compile USB Host Application

["Navya S Kamath" <navya@coreel.com>]

Hi,

Could you please elaborate on how to compile the host application? The
ECOS_REPOSITROY has been installed on the host Linux machine. I use this
repository for compiling the target bootloader along with the USB slave
application.

How can I invoke the target application from the bootloader "Redboot"
prompt? 

If the USB host application has to be compiled on ecos environment, how can
it be executed on Linux?

I am new to ecos environment, please help.

Regards,
Navya

It looks like you're trying to use things that are outside of eCos
(no eCos application should ever need to use 'standard' include files,
only the ones provided)

The public version of eCos doesn't support USB host operations.  I
believe that this can be obtained from eCosCentric.
