Looking for SBC with Heterogeneous Multicore Processor for Drone Development

Check out Milk-V Meles RISC-V T-Head TH1520.

It may not check every box, but it looks interesting...

There are a couple of beagle boards which satisfies your requirements. Community is active and actively maintained. So support is good.

BeagleV-Fire - https://www.beagleboard.org/boards/beaglev-fire

BeagleV-Ahead - https://www.beagleboard.org/boards/beaglev-ahead

BeagleV Ahead RoadTest

There are other options as well

StarFive's VisionFive 2 - https://www.starfivetech.com/en/site/boards

MilkV-Meles - https://milkv.io/meles

You can consider BeagleV Ahead (RISC-V) or NXP i.MX8 QuadMax. 

Thank you guys so far. I am reading Meles Documentation. It is a bit hard to read.

dougw , if I may, I'd like to ask:

• How many Analog in?
• How many PWM ?
• How many audio in?

I guess I'll find the answers in the doc, but if you'd answer, that'd be great too.

BeagleV fire is in my list already.

Beagle V ahead was not in the list, neither was starV - so gonna read their docs now. Thank you

I also joined the beagle discord, and asked for docs to run linux and rtos simultaneously and programming guide. I am waiting for them to answer. If you by any chance, and could share these things with me, I'd be greatful

NXP i.MX8 QuadMax --> i couldn't find an inexpensive carrier. So if you could give me a suggestion would be nice.
Thank you

I saw your message on Discord, it's way too generic. It sounds like you'd need a _lot_ of hand-holding if you're asking for such resources, when your point of call should be the product documentation pages _first_.

Had you done that, you wouldn't be mentioning real-time cores on the Beagle V Fire on your Discord message, because it doesn't have any. It has an FPGA. You'd instead be asking about documentation about how to use the FPGA, and you'd ideally have checked the SoC manufacturer website first too.

Just letting you know not to criticize, but to be realistic, that you're not going to make much progress with this style of approach.

Thank you for the pointers.

I was poised to respond with a suggestion but I applied the adage professional vs personal approach to the solution and changed my mind. This doesn't appear to be a personal project. Those have different requirements than professional ones. My suggestion (Unhiker) provided options with personal market flexibility. Could it be a professional solution? Might but it also might turn into a sow ears and not the silk purse you are looking for.

I couldn't tell if it was a professional versus personal request either. I'm not familiar with Unihiker, but the OP should indeed check it out to rule in or out (and at least rely on documentation to then know what specific questions to ask, since it's too broad to just ask for any and all documentation, and then rule out a device because you later discover what was already apparent from the website/datasheets.

The AMD Zynq-7000 has 2 ARM A9 cores. 

You can place a few MicroBlaze real time cores in the FPGA. There's a FreeRTOS port for them.

Not end-of-life. AMD supports until 2040.

There are boards available. Such as the  Arty Z7 Development Board used in The Eye on Intelligence Challenge. 

The Zynq has 2 ethernet peripherals. I didn't find a board that has 2 sets of ethernet HW on them, though.

The related KRIA has quad cores and 4 network ports. Here's a robotics board:https://www.amd.com/en/products/system-on-modules/kria/k26/kr260-robotics-starter-kit.html

I used Digi boards for another project. Digi has great client support. Take a look at these two stories:
