openwrt compile with error about fsleep()

[charliealexander73]

Hi, compiling openwrt with this feed ends up with an error says that:

"
rtw8822c.c:1482:2: error: implicit declaration of function 'fsleep'; did you mean 'ssleep'? [-Werror=implicit-function-declaration]
fsleep(1000);
^~~~~~
ssleep
cc1: some warnings being treated as errors
"

Can you tell some methods to fix it? Thanks a lot.

I'm using this feed with openwrt master tree

Hi ! Hard to tell, i'm building only 8821cu for my SBC, and i don't know the state of the 8822cu chip in the rtw88-usb development

See issue ulli-kroll/rtw88-usb#4 that says "currently disabled", maybe you should try to open an issue in the driver source repo, as it seems related to a missing update on your chip

Ok I figured out the problem.
Openwrt for my router use a older kernel so that i have to use the backports tree
