AIROC™ Wi-Fi and Wi-Fi Bluetooth Combos

Could someone explain the firmware upgrade process for 1MW with linux.  Does CYW43455 has a bootloader? How to realize OTA through Wi-Fi/BT?

Hi @KOK_4840576, 

Wi-Fi
The Wi-Fi has 2 parts 
a) driver files i.e .ko files brcmfmac.ko compat.ko, cfg80211.ko brcmutils.ko
b) firmware file i.e cyfmacXXXX.bin found in the path /lib/firmware/cypress/cyfmacXXXX.bin
to update the firmware the host could replace the newer .ko files and the .bin file and rmmod and insmod the ko files, this will update the CYW43455 with the latest firmware  

BT
Replace the  XXX.hcd file in the path /etc/firmware/xxxxx.hcd 

Regards
Vivek
