some help with DS-5 - Trusted Execution Environment (TEE)

For debugging, that depends on your platform.

I can show you some key points:

• Add your platform into DS-5 debugger configuration files: refer to DS-5 help documents (DS-5 IDE-> help -> help contents): ARM DS-5 Documentation > ARM DS-5 Debug Hardware > Using the Debug Hardware Configuration Utilities > Creating debug hardware target configurations
• For image/symbol loading: DS-5 can load your image if the target place is writeable, for example: SRAM/DRAM(need initialized). Basically, it's in debug configutrations menu > Files tab > Target Configuration > Application on host to download
• If your target place for image loading is read-only, please put the image to that place using other approaches (for example: flasher tools). Then when your platform gets running, connect DS-5 debugger to your platform, and do reset if necessary.

The other issue I seem to be running into is there is a gap between the tools, which Qualcomm provides for debugging, and DS-5 tools. What I mean is Qualcomm has a debugger for Snapdragon but it needs Eclipse Juno SR1 package. I successfully installed the debugger on this instance. But this instance, as far as I know, can not compile and run the Hello TZ program. On the other hand DS-5 need OpenCL version 8.2 and above, while Qualcomm debugger only works with OpenCL LLDB Eclipse plugin 2.2.2.201.408200918 and CDT version 4.1.0 - 4.1.2. Please have a look at the enclosed diagram...

I get this error when I try to install the debugger even though CDT should be installed on the DS-5 instance that I have. I have tried to look for a version of DS-5 with Juno version of Eclipse but I have not been successful. If it does exist, and you can help me find it, please let me know. I also tried to see if I can add DS-5 functionality an the right patches to the Juno instance of Eclipse on my machine, but I have not seen anything that indicate such install is possible. Please direct me to it if it does.

I like to thank you so much for your continued support. I did place the secure.bin file on my phone, and tried to run the two files in it. I had to change permissions of the files. Here is what I get:

127|root@hltespr:/storage/emulated/legacy/secure.bin # ./SECURE_EXE

./SECURE_EXE

./SECURE_EXE[1]: ▬☻±É╨ƒσ╙≡!πî╨ƒσ►☼◄ε♦└π☺: not found

./SECURE_EXE[5]: syntax error: '┐x┴√╪R' unexpected

Re: The content on Debug Hardware, I did go to DS-5 help documents (DS-5 IDE-> help -> help contents): ARM DS-5 Documentation > ARM DS-5 Debug Hardware > Using the Debug Hardware Configuration Utilities > Creating debug hardware target configurations. But the content does not seem to be very relevant to what I am trying to do. All I have at my disposal is an Android phone model SM-N900P Samsung Note 3 with a USB cable which connects to the laptop. It sounds like ARM DS-5 Debug hardware instructions are for RVI and DSTREAM, which I do not have. I did try to run debug hardware configuration utility, but it does not find any hardware. Did I perhaps miss something?

I think DS-5 can only debug the board when connected with debug interface like: JTAG, SWD.

Please refer to: ARM DS-5 Documentation > ARM DS-5 Debug Hardware > ARM DSTREAM System and Interface Design Reference Guide

I agree. I did review the content, and that is the impression I have. Thank you so much for your help.

Hi Sean,

Sorry, I have not used this debugger of Qualcomm.

So maybe you can open a new topic for the usage of debuuger of Qualcomm.

It is ok. I have since found a way to proceed.

Thanks
