Run and debug Fiasco.OC kernel and L4Re using a DSTREAM JTAG device and the ARM DS-5 IDE

Hello Adam,

Thank you very much for your answer.

I didn't tried yet using an SD card or tftp.
I am interested in testing it using tftp, is there any guide showing how to
setup a working configuration on my development machine?

I compiled the kernel using this command line:
$> make BOOTSTRAP_NO_STRIP=y PLATFORM_UART_NR=1

Now the debugger is not complaining. I have the debug information and I can
also see the source code (as shown in the attached screenshot).

But I still not get the debug information from the kernel in the minicom
serial terminal.
I did a step by step walk through the code, the attached file shows all the
debug information that I get.

Do I used the PLATFORM_UART_NR=1 option correctly, what verification should
I do also?

Thank you very much in advance.

Best regards,
