Hi @vchong
- No problems now. My boot.img is fine
- Ran xtest as root
adb root
adb remount
adb shell
xtest
This is the sequence of cmds - xtest result is here for your reference : http://pastebin.com/V6JAGuSA
For monitor, it was my mistake. I used a DVI monitor and connected hikey with HDMI-DVI cable and there was no display. Now , I am using another monitor having HDMI input and display is fine now.
I think , the key point here is to use direct HDMI monitor
Yep , now I can work on my TA application. Thanks for your quick support
Now , a quick question :
Dont I need optee_os/kernel src code, to build my TA ?
My question arises in the context that , suppose, I give my board to my colleague so that he can verify his TA.
Does he need to have complete stack ( AOSP+OPTEE) like I have ?
Isnt there any on-board security check between TA and optee_os/kernel before TA loads and executes ?
If so , anybody can load their own TA on the board and run it. Isnt this a security loop-hole ?
