[ECOS] eCos 3.0 and TS2750

[ECOS] eCos 3.0 and TS2750

[gmail]

Hi,
I am starting a 'personal project' and would like to use eCos, and I am 
trying to get all of the pieces together.

The board is from Technologic Systems (www.embeddedARM.com) and is the 
TS7250 w/ an ARM9 Cirrus Logic EP9302 on it.

It comes with a redboot loader that loads their Linux port.

I've got cygwin on an XP box and have installed eCos 3.0, but cannot 
find any package for the TS7250 or the ARM9-EP9302 processor.

The s/w that came with the board appears to have the redboot source but 
I think it is a eCos 2.x version.

Is there an existing package for this board or is there a way to 
'import' it from the 2.x source?

Thanks for any pointers in getting going in the right direction!

This board is not part of the public tree.
You should be able to get the original sources from Technologic Systems

I believe the source for the redboot is on the CD supplied from 
Technologic Systems, but I believe that it is for eCos 2.x tree.

Can I just copy that over to the eCos 3.0 tree that I've installed or 
does it need to be 'Imported' via the config tool?

Thanks!

As a starting point, you should be able to copy the directories
containing the additional eCos HAL and driver packages from your TS7250
repository to an eCos 3.0 or eCos CVS repository and then copy the
relevant "package" and "target" declarations from the ecos.db file in
the root of your TS7250 repository to the eCos 3.0 or eCos CVS ecos.db file.

Note that there is also a patch providing full eCos support (not just
RedBoot) for a number of EP93xx parts:

 From what I could tell, the original Technologic boards (TS7200, etc) 
were based pretty closely on the Cirrus eval boards. Technologic started 
their version Redboot using the Cirrus modifications to eCos 2.x from 
about 2005. Cirrus updated their code for a while and released it 
publicly on their web site, but I believe that Technologic stayed with 
the original fork.  A few years back, Brian Austin at Cirrus claimed 
that the company was going to release the code to the public repository, 
but no more was heard from them.

Thanks for the suggestion!

I think that I am making progress as at least I've been able to build 
the library and the tests.

Though I am not able to load the tests either via the 'Run Tests' or the 
Redboot 'load' command.

The 'load' command appears to indicate that the file is not linked 
correctly as I get the error message:

     Abort! Attempt to load ELF data to address: 0x00008000 which is not 
in RAM.

I've tried configuring the Startup type: to RAM but I get a build error 
that the mlt_arm_arm9_ts7250_ram.ldi does not exist.

I am trying build  and load via the Redboot monitor, is this the right 
method for building for that scenario?

Thanks again!

I owe you more than just a couple of beers...

I have not looked at the sources, but you would generally build eCos for
RAM startup if you wish to download to RAM via the RedBoot "load"
command or RedBoot's GDB stub. It would appear that the TS7250 RedBoot
port does not include a linker script for RAM startup, hence the build
error. Perhaps the TS7250 RedBoot port was developed primarily for
launching non-eCos executables?

Compare your TS7250 platform HAL package with other platform HAL
packages to see how mlt_arm_arm9_ts7250_ram.ldi and
mlt_arm_arm9_ts7250_ram.h could be implemented. These files are usually
located in the include/pkgconf/ directory of the various eCos platform
HAL packages.

I hope this helps.

I did implement a mlt_arm_arm9_ts7250_ram.ldi and .h file but it still 
looks like all of the test programs are getting linked at the 0x8000 
starting point.

Running the arm-eabi-size program on one of the test programs (i.e. 
bin_sem0) yields:

bin_sem0  :
section              size      addr
.debug_aranges     0x2318       0x0

.comment            0x8f7       0x0
Total             0x91eed

Looking at the tree in the configtool, this base appears to come from 
the 'Configuration | Redboot for ARM options | Provides the exec command 
in RedBoot | Default physical base address of linux kernel'.

The property info for this value indicates: "This is the physical 
address of the base of the Linux kernel image. This option gets set by 
the platform CDL."

I guess at this point I am totally confused as to how to change this, or 
if I am on the right path.

All I am trying to do is build an executable that can be loaded via the 
onboard RedBoot.

"Clueless at this point"

Thanks for any pointers!
