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.
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.
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:
ARM-USB-OCD-H is a low-cost ARM OpenOCD debugger. It supports targets from 1.65V up to 5.0V. Many SOC manufacturers like Intel, Intel/Movidius, nVidia and others use it in their development work. Intel quotes ARM-USB-OCD-H and ARM-JTAG-20-10 in their appnote “Source Level Debug using OpenOCD/GDB/Eclipse on Intel® Quark™ SoC X1000”.
A few month ago we got an interesting question. A new SOC manufacturer was trying to debug their SOC with ARM-USB-OCD-H, but the problem was that their target was working on 1.2V. They asked us if we could modify our JTAG to be able to work at lower than 1.65V targets.
Our engineers identified a couple of components which we could upgrade to support lower voltages. The final result was that the ARM-USB-OCD-HL new modification of the JTAG can now work with targets from 0.65V up to 5.5V.
This pretty much covers all existing SOCs on the market.
Happy New Year! Olimex team wish you health and best of luck in the new 2021. Let all troubles from 2020 go away!
Update on UK shipping:
Brexit brings some troubles for trade with UK. We stopped the shipping to UK on December 23 2020 as we didn’t know how to handle the orders when we are back on January 4th.
When we got back in office we had expected news: The couriers raised their prices with almost 50% due to the extra efforts around the new UK regulations, but this was just the beginning.
From January 1st 2021 all shipments to UK with value under GBP 135 must be with included charged VAT. For this purpose all online shops which ships to UK must register for UK customs EORI and UK VAT-ID. They have to charge the VAT at the time of shipping and to pay to UK government all collected VAT at the end of the month. The shipments above GBP 135 are shipped with export declaration and without VAT as for any other countries outside EU.
The big platforms like Amazon, ebay etc. also need to register (probably they already did) and collect the VAT from their sellers.
We still not have EORI neither UK VAT-ID so we can’t ship small orders. Orders above EUR 200 are processed normally. We are sorry for this inconvenience and apologise to all our small UK customers.
Update on current boards:
iMX8Qmax board high speed signals are completely routed, we now make the connector arrangements on the PCB and hope to be ready for prototypes in March.
S3-OLinuXino revision B of the board prototypes works great. Bootlin reported that their mainline driver for CSI2 work with RaspberryPi IMX219 8 Mpix camera, CSI1 is with OV2640 2Mpix camera connector. Gigabit ethernet, Audio microphone, PoE option, eMMC/SPI Flash option, etc all are tested and work fine. We are making now final touch ups and will run production.
STMP1-SOM small module with STM32MP151/3/7 is on prototype Revision B and everything exept the Audio is working fine. Production will follow in March.
STMP1-OLinuXino-LIME2 is stuck at Gigabit Ethernet. We had many other issues which were solved, but this remains. The original ST design uses RTL8211 which is commercial grade, we put KSZ9031RNXIC-TR instead and there is neither correctly sent neither correctly received package. We use this chip in Allwinner A20 and A64 designs without problems. We used all combinations of delays of the clocks and singnals etc with no luck. Our guess is the port hardware drivers are somehow incompatible with this PHY and are either slow either make rings which confuse the PHY chip. If someone has more knowledge and can help, we can send board.
