Once/if the first run is sold we will make the laptop out of stock and will work on second run which may take few months to complete, but we will produce this laptop until there is interest for it, so if you do not succeed to order during the first run, do not give up ?ĮDIT: very important notice to add: TERES-I is not designed to scratch everyone’s itch. We guess many of these registered users are duplicated for black and white version and will take just one, but be prepared that after you order your laptop will not be shipped immediately but in 2-3 weeks (or less) depend on workload and number of orders to be processed. This project took lot of time and we have long list of registered interest for ordering, bigger than the number of laptops we could build in the first run. Python libraries to access I2C, SPI, UART, GPIOs will be add when ready.įPGA module with ADC/DACs/IOs will be ready in the next months, it will be easy to insert inside with the other existing boards. The laptop comes with pre-installed Ubuntu 16.04 LTS with Mate, Firefox browser, Video player, Open Office, Arduino IDE and IceStorm for FPGA development. The software is let’s say about 90% ready state, but works satisfactory even now.

Allwinner a64 assembly language update#
Please give us some days to update all latest Hardware files on Github. The adapter has charge indicator and comes with convenient 3 meter cable, so you can lay on your bed while your laptop is connected to power supply.

We got new 9500mAh battery which now is in TERES kit.Īnother improvement is 5V 3A adapter which allow battery to be charged to full in 3 hours. We work on USB-Serial cable with headphone jack for the laptop. After you finish debugging you can restore Headphones functionality to this jack.

The debug UART multiplexes now with Headphones, so you can plug serial cable to headphone jack and re-direct Debug console UART to Headphone jack. We add two new connectors CON3 and CON4 to interface the further FPGA module which will turn TERES-I in oscilloscope and Logic Analyzer. Main board now is with 2GB DDR3 ram and 16GB eMMC Flash memory. It was long way but finally we have laptop which works satisfactory to be released. We are glad to tell you that we finally have TERES-I released!
Allwinner a64 assembly language upgrade#
For the moment we do not recommend you to update and upgrade your Ubuntu packages or if you do this and something stop working to revert to the original image – this is pretty easy just download the image write it to SD card, boot and run the eMMC copy script. We have two reports about problems caused by the touch pad after “apt-get update / upgrade” we have to look more closely into this issue. Add more capacitors to the PWM power supply which to handle this current surge, adding 100 uF seems to remove the problem, but the first lot was already assembled and many laptops are already shipped – so this we will implement in the second assembly.Not very aestetish but quick and dirty solution: adding small double adhesive matt on top of the inductor which make contact with the back plastic and this way absorb all vibrations – we start to add this mat as soon as we discover this issue to all laptops no matter if they buzz or not.play with PWM frequency to get away from this frequency which cause the mechanical resonance – pure software approach which need lot of experimenting.It’s a interesting phenomenia as the backlight PWM is 300Hz which is not possible to hear, but when LCD backlight is switch ON and OFF high current surges are happening and some harmonics cause mechanical resonance with this inductor. We updated this in the assembly manual 1.1 which is now on the web and included in the GitHub too in sources so people who notice typos and want to help improveing the Bulgarian-English language in which the manual is written.Īnother issue reported immediately which we missed during our testing is that on small percentage of the laptops the LCD backlight step-up inductor cause annoying sound when LCD backlight is with 50% brightness. This leaded to laptops not go in suspend mode when lit is closed. Today we shipped all pending orders for TERES-I and we start to get valuable feedback from our customers!įirst thing – we missed the magnet assembly in the instruction manual (blush).
