I am looking for an eval/development whatsoever board with at least 8 ARM64 cores and most important JTAG access to program it bare-metal.
And best would be it is not too expensive (< 1000USD).
Any hint appreciated.
Have you seen: https://www.96boards.org/
they have a number of different dev boards, using a selection of different SoCs.
Yes. But most do not have JTAG. But the HiKey960 looks interesting as there is already support by Lauterbach. Thanks.
Looked through this

doesn't have cache coherent interconnect. Are there, from 96boards, any with the interconnect in one can tell from the top of his/her head?
The Hi3660 SoC at the heart of the HiKey960 board does have a CCI-550 (coherent) interconnect.
Many thanks vstehle. I couldn't find in the board documentation and took it doesn't have it.
Now seeing the CCI. Just to confirm the LLC is L2 (taking in CCI-550 doesn't mention the L3).
The Hi3660 has no L3 cache.
I may start another thread but may be it fits here well: ARM folks help me pick up (not expensive) HW debugger. I want to use it with bere-metal (ATF, Uboot) and the kernel as well (meaning it should have an availability to interrupt all the cpus).
I have experience with Dstream and Lauterbach (trace32). I don't really know the prices for Dstream as I had it always granted from the Customer I was doing the ARM programming for. For Lauterbach I just got a quote for about 6K USD.
Heard also of Segger J-Link for Cortex-A. And yes my interest is in Cortex-A from 53 through 57 to 72/73. Ideally to debug the HiKey960 or 970 which is my buy candidate now.
Take a look at Samsung's ARTIK 710. It's even cheaper than HiKey960 and seems to have all you need.
Thanks, got my HiKey960, but documentation is sparse. I'll look atr ARTIK710 as well.
Do yourself a favor and go for Lauterbach. J-Link does (AFAIK) not yet Armv8-A.
Edit: I checked the board, but it is not clear if one can use "normal" JTAG debuggers with this board.
But the HiKey960 has also a Cortex-A72 which is also interesting (we already have SoCs with Cortex-A53 like ZYNQ US+).
