Hello. Your GitHub link is not working. Can you check it again?
Thanks
Edit: I just found your work in this link: https://github.com/skot/bitaxe, which seems to use the BM1387 chip, not the BM1397.

Sorry, the link has changed. check out the latest branch `max_v2` which uses the BM1397.

We've been discussing this on another thread; https://bitcointalk.org/index.php?topic=5400851.260
Here is the S17 repair guide people are talking about (in case you haven't already found it);
https://www.zeusbtc.com/manuals/Antminer-S17-Hash-Board-Repair-Guide.asp
https://www.zeusbtc.com/articles/information/170-antminer-s17-manual-download
afaik that's as close to a BM1397 datasheet as we're going to get. At least the pinouts for the two different modes are shown.
If you're interested in doing more than just repairing a S17, here is an open source PCB I put together to use the BM1397 chip;
https://github.com/skot/bitaxe/tree/pro
It's still very much a work in progress, so let me know (on GitHub) if you run into any problems.

Does anyone have the datasheet for the IC chips on the T17+ hash boards? I haven't had any luck finding it online for these chips. Thanks
If you want to know the function of the pins of the BM1397AG chip, you can check the repair manual of the T17+ or S17+ hash board, zeusbtc has many related repair manuals, and it is free. In these manuals, the function of each pin is marked. If you want to know other information, then you may need to ask the seller.
Hi this is my first post here, hello everyone!
This information:
Can you please tell me which mode is enabled with high state on MODE pin and which mode with the pin left floating?
Thanks again.
This information:
The different modes are passing data left to right, or right to left. There's a Mode pin which gets tied low for one mode, and left floating for the other. This makes serial power and data in a single copper layer pretty simple to achieve.
Is very helpful already, thanks!Can you please tell me which mode is enabled with high state on MODE pin and which mode with the pin left floating?

The different modes being significant how? do you know?
Thanks.
The 17e series I believe use a different chip, BM1396. The S15 and S17/e chips (BM1391, BM1396, BM1397) are for the most part pin-compatible. 1396 and 1397 have one functional pin difference, but also a different core count and optimal voltage parameters.

The last chip I saw a datasheet for was the BM1385 from the S7. Everything after that we had to work off repair guides and reverse-engineer the rest.
On that note, do you or anyone know what the different modes are and how to set the ASIC in a particular mode?
I'm trying to put together a full schematic and usable (i.e. written in clear, technical English) and intend to share my work. Started with an S17e board that I have knocking about.
Thanks in advance.

AFAIK the s9's were the last miners that BM published chip datasheets for.
Does anyone have the datasheet for the IC chips on the T17+ hash boards? I haven't had any luck finding it online for these chips. Thanks
I found Temperature characteristics from this website: https://www.alibaba.com/product-detail/BM1397-BM1397AG-Original-New-Replacement-Chipset_1600186804769.html
