wifi-img-streamer example stuck on standalone AI-Deck v1.1

[c2wong]

Hi there,

We've got one piece of standalone AI-deck v1.1. After supply 3V using a USB converter board, we managed to bring up the AI-deck v1.1.

We setup the build environment using both latest docker and self-build Ubuntu 20.04 VMware. Both method works on building your sample code. The flash was accomplished using ARM-USB-TINY-H.

We got 2 questions here:

1.

We can build and flash aideck-gap8-examples repository with following commands:

Build:

$ make clean all image PMSIS_OS=freertos platform=board

or

$ docker run --rm -v ${PWD}:/module --device /dev/ttyUSB0 --privileged -P bitcraze/aideck tools/build/make-example examples/other/hello_world_gap8 image

Flash:

make clean all flash PMSIS_OS=freertos platform=board

or

$ docker run --rm -v ${PWD}:/module --device /dev/ttyUSB0 --privileged -P bitcraze/aideck tools/build/make-example examples/other/hello_world_gap8 flash

But we can't make it run using:

make clean all run PMSIS_OS=freertos platform=board

or

$ docker run --rm -v ${PWD}:/module --device /dev/ttyUSB0 --privileged -P bitcraze/aideck tools/build/make-example examples/other/hello_world_gap8 run

It will stuck on last run stage:

TARGET create
DEPRECATED! use 'adapter speed' not 'adapter_khz'
DEPRECATED! use 'adapter driver' not 'interface'
0
GAP8 INIT TARGET
GAP8 examine target
Init jtag
Initialising GAP8 JTAG TAP
Loading binary through JTAG

Is this normal? What can we do to solve it? Some of working examples from gap_sdk works fine with "make run" command.

2.

We already make some examples in gap_sdk to works, including HIMAX camera test, and uart TX/RX, but we are unable to make the wifi-img-streamer example in aideck-gap8-examples repository functional. The build was complete successfully, but opencv-viewer.py stop after finish open connection.

Do you have any suggestion?

Thanks a lot for your time.

1. Can you make sure it is not actually running with the run command? I suspect it may be, and that there are just no printouts arriving to the console. You can verify this with some kind of LED task.
2. Do you mean that the opencv-viewer.py program completely terminates after this "Scoket connected"?

[c2wong]

Hi Rik,

Thanks for response.

1. It seems running because when we 'run' the com-test example, the UART port will output.
2. No, it does not terminated, it just hang there forever.

By the way, We've try to figure out correct combinations. We've managed to make the following combinations to work:

• Ubuntu 18.04
• gap_sdk v3.8.1
• aideck-gap8-examples commit id bdcca78839a0e61baee97e610d9c73b91d9934e8
• Refer to the instructions inside aideck-gap8-examples/docs

But according to my understanding, this version should be using pulpos instead of freertos. We seems can't make wifi-stream example to work on latest(freertos) version.

I noticed there already is a LED blinking task in the streamer example. Can you check if the streamer example is running by checking if the LED blinks after you give the run command?

[c2wong]

Yes, LED blinks while running example on GAP8. Sorry for the late reply.

[gemenerik]

Just to clarify, it is blinking when you give the run command? As in question 1?

And with either method opencv-viewer.py does connect but not display anything. Can you try debugging within the viewer a bit. Do you receive any image data for example?
