I'm not directly involved in BRAZ but have been mining it quite a bit so I want it to succeed.

There's currently an airdrop running here: https://discordapp.com/channels/439073024940048395/478481167931146240

Me and another member are giving 20+10 BRAZ to anyone who posts an address.

Hey dendy77, the discord group is not cancelled: https://discordapp.com/channels/439073024940048395/439073025485176833

Tomorrow is the new launch date for CriptoHub https://criptohub.com.br/en/

BRAZ is listed on their homepage as a supported coin

I'm always going to watch these devs and mine their early coins.

Check out PLUS1 coin - now 500 sats on TradeSatoshi https://tradesatoshi.com/Exchange?market=PLUS1_BTC

It will take time but these guys have good connections!

So, I figured out that I could take my bricked A5 and connect the ASIC boards into the controller board of a working A5 and it works fine

The bricked A5 provides the power and cooling and the working one now gives the workload to all the boards.

Only problem is it only seems to detect 5 boards. 3 from it's own chassis and 2/3 from the bricked A5 even though all 3 LEDs are on.

Any ideas why the controller is only detecting 5 boards out of 6 connected?

Still nice low diff.

Aiming my boys at this

Ugh, so I bought another A5 and it came without an SD card socket in the hole but at least the hash boards have the "catch fire" capacitor removed already (board revision is A5-33S-V3.0a).

I tried to update the firmware to the Feb 2018 via the web interface and it didn't complete and the fault light started flashing continuously. Left it for 30 mins - no change. Ctrl-F5 - no change.

Rebooted it and it now just flashes the fault red light and is not visible on the network on its configured IP address or the default 192.168.1.254

What are my options?

Try to fit an SD socket so I can flash from TF card?

All combinations of reset button, IP set,  and power-on have had no effect.

Anyone selling an A5 controller board? (e.g. you already fried your hash boards).

New firmware out today:

Dear
We are presenting you with an extensive A5 and A4+ firmware upgrade that improves the stability and convenience of the miner greatly. For your benefit, your firmware needs to be upgraded to the latest version (no.12.11 version). Here are the upgrades:
1. Fixed the bug that causes hashrate to decrease, making the hashrate more stable.
2. Added a preheating function before booting, partially sovled the decrease in hashrate due to temperature
3. Further optimized the overheat protection system, so that the miner is more stable.
 
Firmware dodwnload link: http://www.innosilicon.com.cn/download/update.bin
How to upgrade: Follow the appendix of the user manual
Support center: http://www.innosilicon.com/html/downA4/index.html
Thank you for your support of Innosilicon, we will persevere in our efforts to bring you the best user experience. 
Please reply this email,thanks very much.
Wish you a good day.

Hi gvsrusa,

No reply from innosilicon despite sending them diagnostic logs from the bad A5.

The logs suggest it's a temperature problem (board is too hot so gets disabled?)

I've had a few thoughts - the cooling on the A5 seems to be a huge wind tunnel.

Big fans at each end and the boards hang down vertically in this tunnel.

I'm guessing this is their cheap-ass solution to cooling them rather than putting proper heatsink/fans on each ASIC.

I'd have to void the warranty to open it up but I'm considering putting heatsinks on the ASIC chips to see if I can get them cooler.

Cheers,

Tried the 11.24 firmware on my A5 with the bad ASIC board and that didn't fix it.

I did get an email response to my first website enquiry (the default password had been changed before it arrived) and they just advised to flash the 11.24 firmware.

Stil waiting on a response to my bad ASIC board query where I posted details of the debug (obtained by root telnet).

Thanks to whoever sent me the LTC, it's much appreciated

gvsrusa I would suggest downloading and writing the firmware to a microSD card as per the innosilicon manual.

Then boot it up using the microSD card in the slot and leave it a couple of hours to flash (not sure exactly how long it takes but the img was several GB).

Then if you can ping it on 192.168.1.254, pop out the card, and reboot the A5.

Assuming you can now access the web interface, download the other firmware (smaller one) and flash that .bin file via the web admin interface.

If that works then after the reboot, re-configure your network and re-enter your mining pool details.

Good luck! I've had no replies at all from Inno via their web support form yet ...

Hmm, that doesn't look good.

Have you tried pulling the cable from the one you think is the bad board?

From memory, my bad chip is in the low 1/3rd so when the light is out on the left board at least my 2 other boards can mine.

If you disconnect the leftmost board (when the A5 is powered off) then does it at least mine on the other 2?

Have you tried re-flashing via microSD card? (I found the download link for this a bit temperamental but got it downloaded in the end and used Win32diskmanager to write it to my microSD card).

Cheers,

FB

Yes, the A5 has 264 cores on 33 chips (8 cores per chip).

One of my A5's is having a problem with 1 board so I'm only running at 2/3 capacity.

On my A5, on the left most board, the LED goes out as soon as the mining starts. Do your boards stay lit?

Can you post the entire output of --debug here?

Cheers,

FB

Hey gvsrusa,

Just a thought but are you sure you've got the networking set up right?

If it's not mining then perhaps it can't connect (route) to the pool you've specified?

Check your netmask and gateway are the same as the PC you're using to telnet into the A5?

I'm mining in zpool and here are my details


Hope that helps!

Also jizzy87 there is no ssh server on the A5, but telnet should give you the remote access you need.

Telnet server is on port 8100. Username and password as per 1st post.

Hey gvsusa,

If you could send me a few lite that would be awesome - I literally stayed up almost 2 days trying to get access to my A5's !!!

My lite address is LgWMtfdsydYNoCdnnQZJugUJCJhkeuMQTm

One of my A5's is still playing up - only 2 of the 3 ASIC boards are working.

I logged in via telnet and ran the following command to debug the miner:

./innominer_T3 --debug

I don't have remote access right now but you can find the path to innominer_T3 by doing:


Then you can cd to that folder and run the command and hopefully get some output that will help you.

If you don't mind posting the pool details (not the wallet) where you are trying to mine I will see if I can spot anything wrong in your config.

jizzy87:

Try


and then

OK new post created on how to reset the A5 password if you are having problems https://bitcointalk.org/index.php?topic=2455170.new#new

OK, here we go.

I ordered 2 Dashminer A5s and I had the same password problem a lot of you have had but I've discovered a way to get around this.

Now as soon as I post this information and Innosilicon read it I am sure they will change the password in the next firmware so this is only guaranteed to work on the firmware released on 22nd November or earlier.

To find this password I had to disassemble the firmware, find the encrypted password, and then crack it. The whole thing took me 2 days but this method works and will give you back control of your very expensive miner!

If this information helps you out I'd really appreciate if you could drop some Bitcoin BTC to my wallet 1MUfvg7LgFQ2m4BKariD8hZkQJZ5UEMRLS

If you don't have Linux skills then these instructions will be tricky to perform.

Let's get started:

1) Open a command prompt or terminal on your PC, this will need to be on the same network as your A5 and you'll need to know your A5's IP address (probably 192.168.1.254)

You will need to have the telnet program installed so if you don't then you'll need to Google how to install it on your operating system.

2) Test that your A5 is on the network using
If that doesn't respond then you'll need to try other methods to get it on the network (flashing the firmware using the microSD card worked for me).

If you have multiple A5s then make sure only 1 is on the network or you will get IP address conflicts if they are all on the default address.

3) Connect to the telnet server on the A5


4) Enter the username and password:


5) Change to the folder containing the password file


6) Edit the password file with vi as follows:


Press the insert key on your keyboard to enter editing mode
If there is no password then enter 12345678
If there is a password then note it down or change to your choice

7) Now save the password file
enter the key sequence

That's the escape key and then type a colon then wq and then press enter key this means "command-write-quit"

Now you can reset your A5 by pressing the reset button with a pen. After this you should be able to enter the config screen and log in with the password you just set.
