RK3328-SOM-EVB is evaluation board and reference design for RK3328-SOM:
Software support:
Android 10
Linux Kernel 4.4 is the official SDK of Rockchip. There is just basic mainline support with no drivers for USB3 although these SOCs are on the market for quite a lot of time.
Searching for more info about their new H313 SOC I found old news from August 2020, where Allwinner announce the development of AP SOC with RISC-V and praising Open Source Hardware and the open ISA of RISC-V.
They say in this announcement that they will have AP (application processor) SOC with RISC-V in 2021!
There is lot of development around RISC-V in the last years. Espressif have their ESP32-C3 which is with RISC-V SOC, but it can’t run Linux as has not enough memory and video. We still can’t see affordable silicon capable to run Linux.
There is announcement for BeagleBoneV but still not in production and at quite higher price compared to ARM boards on the market.
Allwinner is known to be able to design and produce low cost SOCs. Let’s hope the semiconductor crisis caused by Covid19 will not delay their plans.
So is the year 2021 when we will see $35 Linux running boards with RISC-V?
I’m crossing fingers!
As soon as we can get our hands to these SOC we will make OSHW OLinuXino with it!
OSHW design and affordable SOC will lead to affordable boards and boost of the software development of RISC-V too.
The PCB routing of our most complex board – IMX8QM-Tukhla is complete and ready for first prototype build.
We started this project June-July 2020. Due to the Covid19 the development took 10 months although only 6 month of active work was done, due to lock downs, ill developers and so on troubles.
Now the board is completely routed and has these features:

To the best of our knowledge there is no Open Source Board so far which to be so complex and advanced.
Now we are running the first prototypes and crossing fingers everything to work 🙂
With the current state of the semiconductor industry production will not be possible to be run soon.
Linux support will need attention as NXP has no mainline Linux for this SOC, but only Yocto build for old kernel (4.14.98_2.3.3).
If there are people with experience and interest in this SOC we may share one of the first samples we build, so they can help on the Linux support.
The schematic of IMX8QM-TUKHLA Revision A is uploaded for review on out ftp.
The last issues with STM32MP1 mainline Linux kernel support were resolved and now we run STMP157-OLinuXino-LIME2 in production!
Revision B fixes all hardware issues in the initial prototype. STMP157-OLINUXINO-LIME2 is complete analog of A20-OLinuXino-LIME2 which is one of our best selling Allwinner board.
Mainline uboot and Linux kernel 5.12 images are available with all periperials working.
We will have STMP157-OLINUXINO-LIME2 on our web for sale by the end of April.
This is also our first board with Ethernet supporting Precise Time Protocol and Time Sensitive Networking implemented.
The Time Sensitive Networking (TSN) is for real-time communication with hard, non-negotiable time boundaries for end-to-end transmission latencies.
The main use of TSN is for industrial machine controllers, robots etc.
For this purpose all devices in this network need to have a common time reference and therefore, need to synchronize their clocks among each other. Only through synchronized clocks, it is possible for all network devices to operate in unison and execute the required operation at exactly the required point in time.
The time in TSN networks is usually distributed from one central time source directly through the network itself using the IEEE 1588 Precision Time Protocol, which utilizes Ethernet frames to distribute time synchronization information.
Linutronix helped to implement IEEE 1588 PTP on STMP1-OLinuXino-LIME2.
For Uboot changes Olimex Uboot was used as base. The Kernel patch is sent upstream and can be seen on the mailing list
A64-OLinuXino is Open Source Hardware Quad core 64 bit Linux Computer.
We also offer nice metal box for it named BOX-A64-BLACK:
The only problem was that A64-OLinuXino have option for on board WiFi-BT but it uses PCB antenna and when put in box the communication range was decreasing signiificantly.
New revision of A64-OLinuXino board now supports both internal PCB antenna and U.FL externally attached 2.4Ghz antenna.
So A64-OLinuXino can be put inside the metal box and have the antenna outside:
