Hi Gérald, Pali,
For NXP Wi-Fi/BT FW, we only have binary release, which is under
proprietary license.
Regarding the issue, which kind of adapter (PCIe-USB or PCIe-UART) did
you use? Suppose PCIe-USB/PCIe-UART FW may not work on
PCIe-UART/PCIe-USB board. What's the failure symptom?
Thanks,
James

Héllo James,
As Pali wrote, if fimrware requires signing NDA, I can propose my own
collaboration to NXP !
I am still okay to help, in anyway, with testing or more...
Please, feel free to contact me.
