INTEL WIFI AC9620 FIRMWARE LOAD FAILED-Failed to load firmware chunk!

[meerasahibm]

I am trying to integrate intel wifi ac9620 with RISC-V based board which running with linux os 5.17x kernel version. Adding that, we have modified the driver as this board does not support 32-bit DMA mask and changed into 64-bit DMA mask in /drivers/net/wireless/intel/iwlwifi/pcie/tran.c .With this changes, iwlwifi driver loaded successfully also able to detect intel wifi through lspci command. Firmware (iwlwifi-9260-th-b0-jf-b0-46. ucode) also stored in /lib/firmware/ directory. Unfortunately, not able to up the wifi .we are getting following error. Please suggest the workaround for this issue get resolved.Also attached the complete log.

Hello, @meerasahibm.   

Thank you for posting on the Intel® communities.  

It is worth mentioning that Intel does not support wireless integrations (installing a different wireless adapter into your system/laptop). We recommend you speak to the Manufacturer of your equipment for support on wireless integrations and replacement parts to ensure compliance with the regulatory requirements of your country and support. It is important to check for compatibility with the System Manufacturer, as there could be certain cards that will not work with the system.  

For more information, read the following article under the title "Regulatory Information Regarding Wireless Hardware Installation or Upgrade."

Thanks for reply.  this intel Wi-Fi adapter is working with other RISC-V board with generic intel wifi driver which i am using in my board. I was thinking will there be any latest patches available from intel regarding firmware. Ultimately, I will check with manufacturer for compatibility and compliance.
