HDDL Support on ARM Platform or not

[SC_Huang]

Hi, 

Our customer had try the openVINO raspbian version could work with NCS2 with Ubuntu16.04 on ARM v7 platform (32bits)

Does HDDL card also work with Ubuntu16.04 on ARM v7 or v8 platform (32bits or 64bits)?

It seems no HDDL plugin in openVINO raspbian version, can we use openVINO Linux version instead?

Dear SC Huang,

Raspberry Pi has an ARM chip and certainly, you can use it as a host with a Myriad stick plugged in. For Raspberry Pi, you must use the raspbian 32-bit OS.

If you are talking about an accelerator board like Mustang-V100-MX8 then 64-bit Linux OS (such as CentOS and Ubuntu) are supported. 32-bit Linux is not supported on this accelerator board.

Hope it helps,

Thanks

then, i tried to rebuild these two module with the 4.4.167 kernel (downloaded from https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/linux-4.4.167.tar.gz) but the same issue mentioned above appeard. Now it's blocked here...

Q: Do you have some good ideas ? Or could you give me some good suggestion or sth? 

tks
