 +===== What? =====
 +Looks like an affordable RISC-V board, got the 8GB RAM model. Shipped from Shenzen/China in 3 days to tokyo. Waiting for the power supply.
  
 +  * https://pine64.com/product/star64-model-a-8gb-single-board-computer/
 +  * Star64 model A SBC, featuring the StarFive JH-7110 SoC
 +  * quad-core SiFive U74 RISC-V 64bit CPU with an IM BXE-4-32-G52-2EE GPU
 +  * power connector: 
 +    * 12V 3A or above type M 5.5mm OD/2.1mm ID barrel type DC Jack Connector
 +    * https://en.wikipedia.org/wiki/Coaxial_power_connector
 +    * This is the one I ordered: https://www.amazon.co.jp/-/en/gp/product/B07XKRCPTN/
 +    * power consumption: I saw 4-8w consumed
 +  * [[https://wiki.pine64.org/wiki/STAR64|Data sheets, bringup infos]]
 +  * [[https://blog.fluxcoil.net/posts/2023/05/star64-first-look/|My blog article]]
 +  * https://github.com/takayuki-nagata/u-boot/wiki
 +
 +===== Distros =====
 +  * [[https://forum.pine64.org/showthread.php?tid=18291|armbian]] ([[https://forum.armbian.com/topic/28912-star64-jh7110/|direct]]) - that looks most usable to me right now
 +  * [[https://wiki.debian.org/RISC-V|Debian]]
 +  * [[https://fedoraproject.org/wiki/Architectures/RISC-V|Fedora]] - I got a report that Fedora userland + non-Fedora kernel can be used to book the Star64, haven't done that myself - haven't yet tried.
 +  * [[https://en.opensuse.org/openSUSE:RISC-V|SuSE]]
 +
 +===== First boot =====
 +  * For first boot, I used the image from https://pine64.my-ho.st:8443/ . Now I use image Armbian_23.09_Star64_sid_current_6.1.31.img.xz from [[https://disk.yandex.ru/d/eEC4riP1jBWCeg/ArmbianTV/20231123-current|here]]
 +  * Write that to an sd-card
 +  * You can use a HDMI2usb converter to capture the output, and connect a usb-keyboard for input
 +  * or use serial connection:
 +    * provides more details/direct access than HDMI
 +    * Connect a usb/serial converter, connect the GND pin of the converter to for example pin6 of the star64, the adapters RX pin to the star64's pin8 (which is TX), and the adapters TX pin to the star64's pin10 (RX)
 +    * Execute "screen /dev/ttyUSB0 115200,cs8"
 +    * [[https://files.pine64.org/doc/star64/Star64_Schematic_V1.0_20220721.pdf|pin schematics]]
 +  * later SSH login gets possible
 +  * login pine64/pine64, 'su -' / root-password is pine64
 +

 +</code>
 +  * By default, armbian is setting up a 50MB tmpfs for /var/log. That's running out of space when updating the system, I increased it to 300MB in file /etc/default/armbian-ramlog .
 +  * I added audit=0 in /boot/extlinux/extlinux.conf to disable audit.
