Title: black box for avalon 921 Post by: Posholak on January 06, 2021, 12:36:30 PM Hello!
I really need help with the black box (I have 3 of them). I tried to flash one with this firmware https://download.canaan-creative.com/avalon921/openwrt/latest/h3/, openwrt-sunxi-cortexa7-device-sun8i-h2-plus-vidtoo-model-a Here is a photo of a web page with firmware https://ltdfoto.ru/image/kglV8 loading went and after silence, then there were only blinking of the diodes of the network board even with the cable disconnected (there is a blinking frequency). I tried to flash the firmware below as I saw the inscription Vidtoo H2 on one of the pages. https://ltdfoto.ru/image/kdq9j https://ltdfoto.ru/image/kgAZi https://ltdfoto.ru/image/kdYiV I sent a photo of the board to my friend, he said that when searching, rpi3 comes out, and said that you need to flash mm, after the mm firmware the connection did not disappear, I thought everything was fine and then I stitched it with the link below https://download.canaan-creative.com/avalon921/openwrt/latest/rpi3-modelb/, openwrt-brcm2708-bcm2710-raspberrypi-3-rootfs after which I received a box with the same condition as the first, I'm afraid to touch the third box. I PLEASE HELP WITH THE RESTORATION OF THE BLACK BOXES AND THE CORRECT FIRMWARE OF THE THIRD BOX UNDER AVALON 921 (VALID FIRMWARE FOR AVALON 8 SERIES).

I used to have a few of them and they all gave me issues. While I was still running Avalon 8's and 9's I went all RPi, and never had another issue.
The other issue IIRC is that there were some hardware revisions of the non RPi stuff that would work with the A7 and A8 firmware but not the A9. You would have to dig it up but it was discussed someplace. -Dave Title: Re: black box for avalon 921 Post by: Posholak on January 08, 2021, 01:37:58 PM Hello! Thanks for the help.
Can you post a link to an article with these devices ?? Help please, there are 3 boxes and avalons of 921 models, if there is an article where it is written that A8 boxes will not work with 921 models, then I will ask you to send others.

Raspberry Pi 3 model B+ does not work with it. These work ok: AvalonMiner Controller (this is a steel case with Raspberry Pi 3 model B inside) Raspberry Pi 3 model B Raspberry Pi 2 model B Raspberry Pi 1 model B+ You can see my guides for help (see below). |
