How do I add a serial driver?

How do I add a serial driver?

[Paul J THACKER]

I'm porting ECOS to a new platform, based on the ARM926. I cloned an 
existing platform and got everything to compile, but I can't figure out 
how to add the serial driver.

I cloned an existing driver and added it to my cdl files. It shows up in 
  Build->Packages, but when I try to add it, I get a message that says 
"Add and remove hardware packages by selecting a new hardware template".

I tried a couple of other platforms with the same result. I'm clearly 
not understanding this process. Can anybody help?

Thanks,
Paul

Hardware packages should be part of the basic target template:

target h8max {
        alias           { "H8MAX" }
        packages        { CYGPKG_HAL_H8300
                          CYGPKG_HAL_H8300_H8300H
                          CYGPKG_HAL_H8300_H8300H_H8MAX
                          CYGPKG_IO_SERIAL_H8300_SCI
                          CYGPKG_DEVS_ETH_H8300_H8MAX
                          CYGPKG_DEVICES_WATCHDOG_H8300_H8300H
        }
        description "
           The h8max target provides the packages need to run
           eCos in the strawberry-linux.com H8MAX board."
}

Hi Andrew,

Thanks for responding. I added it to my template:

target cartesio {
         alias { "Cartesio (ARM) board" cartesio }
         packages { CYGPKG_HAL_ARM
                    CYGPKG_HAL_ARM_ARM9
                    CYGPKG_HAL_ARM_ARM9_CARTESIO
                    CYGPKG_IO_SERIAL_ARM_CARTESIO
         }
         description "
         The Cartesio HAL package provides the support needed to run
         RedBoot on the ARM processor of the Cartesio.

}

package CYGPKG_IO_SERIAL_ARM_CARTESIO {
     alias             { "Cartesio evaluation board"
                         devs_serial_arm_cartesio cartesio_serial_driver }
     hardware
     directory         devs/serial/arm/cartesio
     script            ser_arm_cartesio.cdl
     description       "Cartesio evaluation board serial drivers."
}

I added the code to packages/devs/serial/arm/cartesio/ - basically 
copied the AT91 code and modified it for my board.

When I rebuild, the serial driver doesn't get compiled. The 
build/io/serial/ does get compiled. I'm sure I'm missing something 
basic, but I can't figure out what it is.

Thanks,
Paul

Take a look at CYGPKG_IO_SERIAL_DEVICES.

I enabled Hardware Serial Device Drivers (CYGPKG_IO_SERIAL_DEVICES) in 
configtool - no difference.

So you need to look at your configuration and work out why your serial
driver package is not active.

eg the top of the AT91 driver has:

cdl_package CYGPKG_IO_SERIAL_ARM_AT91 {
    display       "Atmel AT91 serial device drivers"

    parent        CYGPKG_IO_SERIAL_DEVICES
    active_if     CYGPKG_IO_SERIAL
    active_if     CYGPKG_HAL_ARM_AT91

We know you have CYGPKG_IO_SERIAL_DEVICES enabled. Does your
configuration have CYGPKG_IO_SERIAL enabled? Does your package still
require CYGPKG_HAL_ARM_AT91 which is not true for your hardware? Have
you made a typo in the name of the replacement?

Look at your ecos.ecc file. You can learn a lot from that.

Not sure how to tell. It doesn't say one way or the other in configtool.

Does your package still

Don't think so. I've looked it over pretty carefully.

Don't have an ecos.ecc. Do you mean ecos.db?

That is why i recommended looking in the ecos.ecc file.

Nope. In your work directory. It might be named something else, but
similar, since you are using the configtool. ecosconfig always calls
is ecos.ecc by default.

Ok, I found the ecc file. CYGPKG_IO_SERIAL_ARM_CARTESIO wasn't there, so 
I added it by hand. Now it shows up in configtool, but it's grayed out, 
and still doesn't compile.

Thanks,
Paul

You should never need to add things by hand. If it is missing, it must
be because it is not part of you current configuration.

CYGPKG_IO_SERIAL_ARM_CARTESIO is a hardware package? And you added it
to your CARTESIO target in the ecos.db?

Do an 

ecosconfig export config.ecc 

and send config.ecc.

Just send the .ecc file you said you found, or make sure you
are in the directory where it resides when you run 'ecosconfig'

Looks like you just had a spelling error.

You're not really using version 2.0 are you?  It's now 6+ years old!
The best source tree is from CVS - using anything else is fraught
with trouble...

Yes, but I had to correct it in the ecc file, which I've been told I 
shouldn't have to mess with. But it's working anyway, so I'm happy.

Yes, I'm using 2.0. I can't get to CVS through our company firewall. I 
could download it from home, but I don't really want to start over. In 
case I end up doing that anyway, which version of gcc (ARM) are you 
using now?

Paul

eCosCentric makes snapshots of the CVS tree which you should be
able to download.  As for the compiler, there's no need to change
from something that works.

The CVS tree is so vastly different from the old 2.0 release
that it makes it difficult for us to even discuss when you
have problems or questions.

Ok, thanks. I'll download the latest.
