We have enough business to place custom orders even for chips which are now with status “obsolete” and Allwinner keep producing them for us. This is why many people are afraid to place Chinese SOC in their products, they are afraid that this chip may stop being produced at some point of time and their design need to be changed.įortunately for Olimex our sales are big enough to be interesting and supported by Allwinner. While NXP, ST etc always keep some kind of guarantee that they will produce this processor for XX years, Chinese companies are practical, they sell as long as it’s profitable for them and if demand is low they just stop. During the last COVID-19 economy slow down these customers decreased and Allwinner stock of T2 was sold out. T2 can work in extended temperature grade and is more expensive than A20, so the demand is not so big and used just by specific customers like in automotive and industrial equipment. We are proud that our OSHW designs with A20 are part of this success story. It keeps selling for more than 8 years now and demand is steady. T2 is the industrial version of A20 – the most successful SOC in Allwinner history. If someone has more knowledge and can help, we can send board.

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. We used all combinations of delays of the clocks and singnals etc with no luck.
We use this chip in Allwinner A20 and A64 designs without problems. 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 had many other issues which were solved, but this remains. STMP1-OLinuXino-LIME2 is stuck at Gigabit Ethernet. STMP1-SOM small module with STM32MP151/3/7 is on prototype Revision B and everything exept the Audio is working fine. We are making now final touch ups and will run production. Gigabit ethernet, Audio microphone, PoE option, eMMC/SPI Flash option, etc all are tested and work fine.

Bootlin reported that their mainline driver for CSI2 work with RaspberryPi IMX219 8 Mpix camera, CSI1 is with OV2640 2Mpix camera connector. S3-OLinuXino revision B of the board prototypes works great. 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. We are sorry for this inconvenience and apologise to all our small UK customers. Orders above EUR 200 are processed normally. We still not have EORI neither UK VAT-ID so we can’t ship small orders. also need to register (probably they already did) and collect the VAT from their sellers. The shipments above GBP 135 are shipped with export declaration and without VAT as for any other countries outside EU. 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. For this purpose all online shops which ships to UK must register for UK customs EORI and UK VAT-ID. 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.įrom January 1st 2021 all shipments to UK with value under GBP 135 must be with included charged VAT.

We stopped the shipping to UK on Decemas we didn’t know how to handle the orders when we are back on January 4th.
Let all troubles from 2020 go away!īrexit brings some troubles for trade with UK. Happy New Year! Olimex team wish you health and best of luck in the new 2021.

OSHW design and affordable SOC will lead to affordable boards and boost of the software development of RISC-V too. So is the year 2021 when we will see $35 Linux running boards with RISC-V?Īs soon as we can get our hands to these SOC we will make OSHW OLinuXino with it! Let’s hope the semiconductor crisis caused by Covid19 will not delay their plans. There is announcement for BeagleBoneV but still not in production and at quite higher price compared to ARM boards on the market.Īllwinner is known to be able to design and produce low cost SOCs. We still can’t see affordable silicon capable to run Linux. Espressif have their ESP32-C3 which is with RISC-V SOC, but it can’t run Linux as has not enough memory and video. There is lot of development around RISC-V in the last years. They say in this announcement that they will have AP (application processor) SOC with RISC-V in 2021! 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.
