is there anyway you could process these files for me?. I would be willing to send you the files and go through some back and forth of feedback and whatnot. The issue is I just don't think I have the time or the expertise to devote to this. However I investigated exchanging the laptop to get a Linux compatible one, but its going to cost me money for the restocking fee. On top of that the next user of this laptop will be disgruntled when they find a non working copy of Linux on it. I investigated getting the restore cd but Lenovo's charging $70 for the media. So if you could help I would really appreciate it because this is the last thing that I need to get working but I really need it.
and we could also get this chipset supported. I saw I wasn't the only one looking for Linux support for this driver.

I have these files. Awesome. eeprom_ar6320_2p1_NFA354xp.bin looks like a board.bin. qca61x420.bin looks like main program binary. > However I am now diverging from your instructions considerably.

I think I understand the part about the > ath10k format though. OTP is a calibration related program which is run on device before running main program. It's embedded inside ath10k FW API blob. > Could you update your instructions to suit the new information at hand? https://gist.github.com/kazikcz/c970cbf3a863ebbc4495 https://gist.github.com/kazikcz/64313b9e2470660faae1 Here are two simple and crude tools I have to deal with ath10k FW API blobs. Use with care. You can use the disassemble.py to extract the otp.bin from hw3 ath10k FW API blob: python disassemble.py < /lib/firmware/ath10k/QCA6174/hw3.0/firmware-4.bin Then you can use the assemble.py to generate hw2.1 ath10k FW ABI blob: mkdir -p /lib/firmware/ath10k/QCA6174/hw2.1/ python assemble.py killer1252-testfw 0 path/to/qca61x420.bin path/to/otp.bin 4 > /lib/firmware/ath10k/QCA6174/hw2.1/firmware-4.bin cp path/to/eeprom_ar6320_2p1_NFA354xp.bin /lib/firmware/ath10k/QCA6174/hw2.1/board.bin (mind the email line wrapping) Michał _______________________________________________ ath10k mailing list email@example.com http://lists.infradead.org/mailman/listinfo/ath10k
