Hi Charles,
In the future, the best place to post this type of question is the OKL4
Developer Mail List. I am forwarding your question to that address.

Thanks,

Subject: Report problem

Hello,

I don't know if I am sending this report at the right address but I hope
that it will be usefull...

My aim is to use the OKL4 SDK for an ARM926 architecture, so I followed
exactly the steps describing on the FrontPage Developer of your wiki :
    - Use the provided toolchain
    - Get the provided Qemu and installed it as it explained
    - Downloaded the suitable SDK for ARM926

After that, I built an example found in the "examples" directory of the
SDK, I chose the "singlecell" example. I would run it with Qemu with the
same command given on the wiki and my problem happened at this step!
The simulation seems blocked and nothing appears!

I hope (for you) that the problem comes from me, otherwise it means that
there is something wrong on your side. Besides, I tried to do exactly
the same simulation with the SDK for ARM1136 and it worked well!

If you have any idea about how to fix that, please inform me.
Sincerely yours,
Charles-Basile Rouquette

I just wanted to avoid any misunderstanding on my previous email. I did
not mean to be provocative...

Thanks for your help :)
Best regards,

Hi,

I'm still investigating the startup issue for OKL4 on versatile in QEMU.

I saw in log file from Qemu (attached) that it seems blocked when
executing the code of the "console_putc" function found in "kdb.c"
source file.
"kdb.c" located here: "sdk-okl4-arm926/kernel/arm926ejs/soc/versatile/kdb"

It seems that the "CONSOLE_PORT_SERIAL" pragma is not defined, which is
strange. Is it the default behaviour ?

Thanks,
Charles-Basile Rouquette
