There is a USB host application in the eCos sources that you compile on 
a desktop Linux and use to help test the USB slave device that you 
create with eCos. You don't *need* the host app to create a USB slave 
device with eCos. It just helps you debug one if you do have it.

It is not clear that usbhost is going to compile easily on any current
Linux system due to incompatible changes in the Linux world. For
example my Fedora 7 system no longer has a <linux/usb.h> header,
instead there is a <linux/usb/ch9.h> header which appears much to have
the same contents.

However I think that your immediate problem is that the build is
picking up the wrong header files. I do not know where
/usr/local/include/stdio.h comes from, but the usbhost build should be
using the official header files from /usr/include.

RE: [ECOS] Compile USB Host Application

[Navya S Kamath]

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.
