Debug ODROID-Q2 over JTAG

Unread postby zandr » Tue Jun 10, 2014 10:54 pm

Hi,
How can I use JTAG for ODROID-Q2 debugging? Required hardware/software from PC side?
In Platform Accessories > Debug Board [TTA20 to Debug Board ] (http://www.hardkernel.com/main/products ... 4700550977) I saw mentions of "ODROID Serial debug port via CP2104 to host PC:" - what is it?

Thanks.
Andrei.

Hello.

For JTAG you also need: http://www.hardkernel.com/main/products ... 9690280462

That's a 20-pin arm jtag.

Note that you need to license SecureJTAG from Samsung to use it.

Thank you for prompt reply.

1) Does [TTA20 to JTAG Board], you mentioned, connect directly to ODROID board? And what is the purpose of Debug Board [TTA20 to Debug Board ] (http://www.hardkernel.com/main/products ... 4700550977) then? What is "ODROID Serial debug port via CP2104 to host PC" for? How can it be used?

2) Concerning SecureJTAG. Some guys that use Arndale board (Exynos 5250) say that it supports non-secure JTAG debugging and they use it - http://forum.insignal.co.kr/viewtopic.php?t=179&p=580.
Does Q2 mandatorily require Samsung license?

1) Nope. There's two boards required for JTAG. One is the http://www.hardkernel.com/main/products ... 4700550977 then the http://www.hardkernel.com/main/products ... 9690280462 is connected to it.
As for serial access:
Linux: viewtopic.php?f=53&t=71
Windows: viewtopic.php?f=53&t=73

2) As you can see from Godori answer you need to license SecureJTAG with Samsung.
