Are you running an embedded system on the board? What do you mean by "developing"?

Hi Rollo_castel and welcome to LQ.

Please note that your question is unclear as well as poorly titled and worded. Please take the time to review the Site FAQ link shown in the Main Menu on the side of all LQ pages.

For now, in similar form to AwesomeMachine's query, I'm seeing that the Hi3520D is actually a DVR H.264 Codec chip and not a board. There are some development boards out there, and one link I found with information had very unusual things, it had paragraph descriptions, not highly specific and where they had intentions for hyperlinks, I saw [email protected] where I chose to not click any further. Imagine this paragraph right here which you are reading and insert about TEN of those [email protected] items within this very paragraph at random places. That's how bad it was. I therefore didn't characterize their information as all that worthwhile.

Here's that page if you really wish to peruse it:

There seems to be a demo system you can find:

I do not see a great deal of helpful information about this. If they really wished people to use their chips and boards, they likely would be more forthcoming and offering of information.

To make matters worse, you go to their website and click on support and you see this, which for me brings me to a terse login screen with about zero additional information. I'm noting that this does not tell you how to create an account and when I clicked on the help link, it covers all kinds of help for login problems if you forgot your password, and etc, but little information about how to create an account.

It would seem to be non-feasible that I, or many others on these forum, could be able to help you. You need to contact Hisilicon and ask them for more information about this chip and their demo boards.

It depends witch Hi3520d you have, they aren't all the same apparently.

I have been playing with my NVR (OEM NV21A08-P8-S2 / Dahua NVR2108-8P-S2) recently and it has a Hi3520dv300 chip which is an Arm Cortex-A7.
The Hi3520dv200, however, is an Arm Cortex-A9.

It can be hard to find, but the Hisilicon SDK archives you want to look for are:
Hi3520D_V100R001C01SPC050.rar for the Hi3520dv200
Hi3521A_V100R001C01SPC040.rar for the Hi3520dv300 (It's bundled with the Hi3521A's SDK)

I had to search through Chinese sites to find all this info and the SDK archives. Once you get the archives though they have English manuals in them.

I actually ended up having to use Hi3521A_V100R001C01SPC030.rar as the only copy I found of the newer version had a corrupted archive in it.
