Hi,
I want to port driver for CYW43455. I used this Cypress Linux WiFi Driver Release (FMAC) [2020-06-25] ,
Target platfrom is ST sta1275 DV12.5,
During the cross compilation of modules, I have seen the following warning.
root@sta1275-evb-mmc:~/aher_ko# insmod compat.ko
insmod: ERROR: could not insert module compat.ko: Unknown symbol in module
dmesg shows :
[ 59.569745] compat: Unknown symbol kmem_cache_alloc_trace (err 0)
[ 59.569905] compat: Unknown symbol __gnu_mcount_nc (err 0)
Could you help to fix this issue? Thanks a lot.

hi @aher2600 ,
Please check all dependencies of the module before loading it., usually these dependencies are enabled in the .config file of the kernel.
Please refer the section 3.3.5 Frequently encountered issues, point 2 of the following document -> https://www.infineon.com/dgdl/Infineon-AN232689_-_Wi-Fi_software_user_guide-ApplicationNotes-v01_00-...
