test_camera example

[Donghong]

Hi.
I am working on Ai_deck1.1 with the test camera example but the process stops at:
Entering main controller
Testing normal camera capture
Opening Himax camera
Different from issue viewtopic.php?f=21&t=4847, my programmer (olimex-arm-USB-tiny-h) red light doesn't flicker. And also, the wifi streamer example doesn't work. it stops at: Allocated Memory for Image.

Some may help to know more about my problems.
ubuntu18.04 in the virtual machine(VM)
the SDK version 3.8.1.
the command I input: make clean all run platform=board

Thank you!
Zeng

sorry, my programmer (olimex-arm-USB-tiny-h) red light also flickers. I mistook it for the LED on AI_deck.

Do you still have an issue or you managed to solve it?

I still have the issue.

It looks like the problem is camera related. Did you test to remove the JTAG while power cycling the CF2.1 as described in this post?

Thank you for your reply~
I power on CF2.1 and remove JTAG, then reconnect JTAG and run the test_camera example.
It still stops at:opening Himax camera .
did I mistake " power cycling the CF2.1"?

You should remove JTAG. Power off then on the CF2.1 and then connect the JTAG to make sure the camera is not "phantom" powered though the JTAG.

Thank you very much! I can run the example successfully.

Just in case someone else has the same problem, I will write down the detailed process.
1. Connect the programer(USB) to the computer, but do not connect (JTAG) to the CF2.0.
2. Power on CF2.0 with battery instead of USB power supply.
3. Connect the programer(JTAG) to the CF2.0, then run the example.

I'm glad it works now and thanks for the step by step guide!
