Bring up temperature is -64

[Perverza]

Hello,

I have interesting problem with T17e, connected is only 1 bad hashboard.
Where is a bring up temperature sensor located? is it one of 4 sensors on the board ?
Hash board sometimes booting up without hashing and after 5minutes reboot.
Problem with MOS, DC/DC ? Overcurrent ? or soft voltage ?
Control board find 78 asic chips.

And second question, what means "domain d0,d1,d2,d3 ?

Code:

2021-08-15 16:10:43 chain 0 domain  3: d0 0.334, d1 0.329, d2 0.333, d3 0.320, sum = 1.316162

Here is part of the log:

Thank you.

Have you noticed the error?

Code:

2021-08-15 16:11:11 driver/driver-btm-api.c:204:set_miner_status: ERROR_TEMP_TOO_LOW
2021-08-15 16:11:13 driver/driver-btm-api.c:717:killall_hashboard: ****power off hashboard****
2021-08-15 16:11:13 driver/driver-btm-api.c:157:stop_mining: stop mining: Environment temperature is too low!
2021-08-15 16:11:13 driver/thread.c:1732:cancel_read_nonce_reg_thread: cancel thread

I don't know exactly what are d0,d1,d2, and d3 it might be an ASIC chip or a driver.

About the error temp too low what is your environment temp or room temp?

I would suggest you if you want to troubleshoot your hashboard check this guide from zeusbtc here https://zeusbtc.com/NewsDetails.asp?ID=185
But your problem seems not a hardware issue.

Where is a bring up temperature sensor located? is it one of 4 sensors on the board ?

There is no bring up sensor, the miner tries to warm the hash board to normal operation temp, it uses the 4 sensors to obtain the current temp.

Code:

2021-08-15 16:11:13 driver/driver-btm-api.c:157:stop_mining: stop mining: Environment temperature is too low!

What is the room temperature? these miners can't function well if the room is too cold.

[Perverza]

Temperature in room is about 27 ° C = 80.6 °F .

Other hash boards work fine... this hash board was repaired in china or bitmain repair center, working only 1 day .
