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.

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

[ECOS] fis list

[hong zhang]

List,

"fis list" returns something like

Name             flash addr  Mem addr   Length   Entry
point
RedBoot         0xA0000000  0xA0000000 0x020000
0x80000000
RedBoot[backup] 0xA0020000  0x8C010000 0x020000
0x8C010000
RedBoot config  0xA0FC0000  0xA0FC0000 0x020000
0x00000000
FIS directory   0xA0FE0000  0xA0FE0000 0x020000
0x00000000
RedBoot>

What is real meaning Mem addr and Entry point? I read
redboot manual but no answer.

'Mem Addr' is the address that this image will be loaded to RAM
if you execute 'fis load' with no memory options.  This can always
be overridden using the '-b' option.

'Entry Point' is the default address if you were to execute the
code, via the 'go' command.

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.

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.
