This week was episode 3 or our 3 part series on the DragonBoard 410c and was Live from Linaro Connect Las Vegas 2016 (LAS16). This week was a panel discuss held during Linaro Connect, it was attended by both a live audience and by those on the OpenHours hangout as well. There was a lively discussion about 96Boards and several questions from the audience.

welcome

Do db410c supports u-boot apart from LK?
PR
Is anyone here familiar with Qualcomm Adreno GPU ? and specially opensource drivers ?
PR
this page was edited in January :https://github.com/freedreno/freedreno/wiki/Status
S
Is there chance for dp 410c to get full Google support for OS like Android
S
Why can’t serial port just made available on board.. its 1st hand requirement for developer.. ultimately need to spent peeny either from developer’s pocket or from board cost..
I hope it boots GNU/Linux
RW
It can
PR
One question, is there any 96 board with full support using 100% opensource BSP ?
S
want to use Creative webcam with dragonboard (via usb), for open CV program, is it possible?
Sure
PR
does v4l supports your device ?
RW
@sushant yes
USB camera should work out of box
PR
if yes I think you need to try , and benchmark performance…
Maybe you’re expecting hardware acceleration for OpenCV ?
I am not familiar on this subject, but I think OpenMAX API are suposed to provide hardware abstraction API
S
thanks!

I’m hoping when I filled out the form last week I did it right =p
PR
For instance, RPi BCM VC1 uses omxplayer for video, but I think it’s more than just codecs, there are also algorithms like FFTs etc
do i need any specific library for camera (python)
Here is welcome keynote from Linaro Connect, there are some 96Boards announcement in here https://www.youtube.com/watch?v=BnQZiXpN3cQ
S
can we get tutorials( videos or documents ) to access hardware part of db 410 using Android IDE platform
PR
S: openCV
is providing python bindings isnt it ?

PR
Isnt neon part of ARMv8 ?
RW
Ill ask in a second Phil
PR
NEON is included in all Cortex-A8 devices but is optional in Cortex-A9
RW
@sushant you minght want to look for a good debian packae
PR
according to wikipedia
RW
package
@phil, you should speak up
challenge our panel
One question, what about support of ARM TrustZone ?
RW
where to find it? or on what board?
T
adding a serial port is as easy as buying the mezanine UART
PR
This is a trendy feature, specially in IoT domain where security matters.
RW
I wish more companies in the IoT space felt security matters.
Instead of being first to market
RW
Anyone have questions for the panel?
PR
I keep mine old lappy w/ RS232 DB9
RW
lol
T
it’s rare to do board bringup on a laptop
RW
My responsibility is IoT security for my job and every day a new product comes out and I just /facepalm
J
We use FTDI USB Serial
PR
I used a RPI as a UART console long time
RW
At least my company lets me play with all the new stuff
RW
How we get the chat on the screen
nvm
J
yes
PR
Max232 adapters are not that expensives
J
IoT has a lot of interfaces serial and we need them
PR
what is everyone focused on UART?
RW
More uart talks! Lol
PR
-What+Why
RW
Hehr
Hehe
RW
www.96boards.org/documentation
this is the new Carbon
PR
is that a MCU or CPU unit ?
Carbon is MCU
running Zephyr ?
T
stm32f401
a SoC from 3 years ago…
RW
lol
PR
yea Zephyr OS
what protocol is used in this demo ?
PR
Pi0 has CPU
Carbon is MCU
and no RAM :P
RW
Phil knows his stuff =)
J
like the nrf51/52??
RW
lol yes
S
so how carbon from particle device
so how carbon different from particle*
TH
What is outlook for BT 5.0 on Carbon?
J
Particle Photon?
S
yes
J
Particle is WIFI
This will be Bluetooth ® wireless technology as I understood
Bluetooth LE
RW
Bluetooth
J
OK
S
ok thanx Marc , Robert
PR
Sorry I was distracted, didnt someone asked about Opensource hardware ?
