NSS Firmware bin find in various Online website.
These are used by the ipq806x and upper SoC to initialize and use the UBI32 coprocessor embedded in the CPU.
There are currently 2 type of Coprocessor tied to the SoC
- AK Akronite ( Ipq806x )
- HK Hawkeye// (ipq807x")
- CP Cypress ("ipq60xx")
- MP?? Maple ("ipq50xx" Maple ipq50xx missing )
Every Letter revision is tied to the QSDK. The Firmware are NOT interchangeable with different QSDK. A mismatch between revision and QSDK version results in the coprocessor NOT WORKING (not packet acceleration, not crypto acceleration)
Revision are incremental. It looks like newer firmware from qsdk 11.3 started using 2.0 naming and with 11.4 they started using qsdk version directly.
- F -> QSDK6.1
- J -> QSDK10.0
- K -> QSDK11.0
- L -> QSDK11.1
- 2.0 -> QSDK11.3
- 11.4 -> QSDK11.4
- 12.0.r2 -> QSDK12.0.r2
For ipq807x and later soc firmware are published on the quic repo as they are now mandatory for the correct function of such SoC.
The last letter R or E means that the firmware is dedicated to the RETAIL market or the ENTERPRISE market. Most of the times R contains more feature than E.
In short to get the right firmware for ipq8064 based SoC with the code based on QSDK 10.0 we should uw AK for the coprocessor type and J for the revision: NSS.AK.F.CS-5-E
