Innosilicon A4+ hardware issue

[zyxul]

Guys,

I recently got 2 Innosilicon A4+ units and realized that one was defective as soon as I saw the LED lights go off shortly after boot in two of the 4 ASC boards it had. The other one happily stayed online with all 4 boards active.

Things I've tried:

1) Swapping the PSU's
2) Swapping the cables
3) Flashing to the latest firmware
4) Checking lose connections on the board
5) Adjusting VDI and Freq in the innominer_T2 args

Nothing seemed to work. The symptom is always the same the board begins with all 4 ASC units lighting up and then 2 of them dying off shortly after boot time. I'm running build: Thu Dec 21 17:56:17 CST 2017

I decided to login via telnet and check the logs of the system and I noticed the following error during initialization which I believe is the software cause:

Code:

Jan  1 22:42:50 (none) local0.info innominer_T2: chain_id:0
Jan  1 22:42:50 (none) local0.warn innominer_T2: cmd reset: poll fail !
Jan  1 22:42:50 (none) local0.warn innominer_T2: cmd write reg: poll fail !
Jan  1 22:42:50 (none) local0.warn innominer_T2: set default PLL fail
Jan  1 22:42:50 (none) local0.info innominer_T2: send command [write_reg]
Jan  1 22:42:50 (none) local0.warn innominer_T2: cmd write reg: poll fail !
Jan  1 22:42:50 (none) local0.warn innominer_T2: #####Write t/v sensor Value Failed!
Jan  1 22:42:50 (none) local0.warn innominer_T2: #####Write t/v sensor Value Success!

Then for chain_id 1 and 2 it succeeds see below:

Code:

Jan  1 22:42:50 (none) local0.info innominer_T2: chain_id:1
Jan  1 22:43:02 (none) local0.info innominer_T2: send command [write_reg]
Jan  1 22:43:02 (none) local0.warn innominer_T2: #####Write t/v sensor Value Success!
Jan  1 22:43:02 (none) local0.info innominer_T2: chain_id:2
Jan  1 22:43:13 (none) local0.info innominer_T2: send command [write_reg]
Jan  1 22:43:13 (none) local0.warn innominer_T2: #####Write t/v sensor Value Success!

And finally for the 4th ASC it fails again:

Code:

Jan  1 22:43:13 (none) local0.info innominer_T2: chain_id:3
Jan  1 22:43:13 (none) local0.warn innominer_T2: cmd reset: poll fail !
Jan  1 22:43:13 (none) local0.warn innominer_T2: cmd write reg: poll fail !
Jan  1 22:43:13 (none) local0.warn innominer_T2: set default PLL fail
Jan  1 22:43:13 (none) local0.info innominer_T2: send command [write_reg]
Jan  1 22:43:13 (none) local0.warn innominer_T2: cmd write reg: poll fail !
Jan  1 22:43:13 (none) local0.warn innominer_T2: #####Write t/v sensor Value Failed!
Jan  1 22:43:13 (none) local0.warn innominer_T2: #####Write t/v sensor Value Success!

The error above seems to match perfectly how it looks in the hardware ie the LEDs turning off from the 1st and 4th board.

Any help will be greatly appreciated.

Hope you all have a great 2018.

Im also seeing one of the board LED off after starting. any updates whether its solved? this A4+ is not even mining anything....

New miner with a new A4+ having hardware issues. Found the command to run the debug. Below is the log, I'm assuming this is no good.

Edit: So my issues weren't hardware, mine was network config issue. My Network Gateway wasn't right, so I wasn't getting to the net.

I'm facing the same problem, one of the board LED is off after starting. and it's even mining anything....
when i used a TF card the device connected to pool and started to mine but one board LED is still off. if i reboot again without the TF card the same trouble occurs "No Mining"
i'm assuming this is a pure software trouble but how could it be resolved ??

Im also seeing one of the board LED off after starting. any updates whether its solved? this A4+ is not even mining anything....

Any chance you solved this? Also facing the same issue. Looked over here: https://bitcointalk.org/index.php?topic=2549898

Still haven't found a solution.
