Dear linux wireless team:
This is Danny, a embedded software engineer
I have successfully run the 8822CE module in Linux kernel 5.4 with imx6 hardware platform.
But it doesnt work in Kernel 6.1 though i have put many efforts to this issue.
So, we'd like to check with you whether the RTL8822CE chip is compatible with Linux Kernel 6.1.
My usage is as below:
- imx6 board
- build RTL8822CE as M in kernel 6.1 menuconfig
- Each time after the board startup, i run four commands
insmod rtw88_core.ko
insmod rtw88_pci.ko
insmod rtw88_8822c.ko
insmod rtw88_8822ce.ko
insmod rtw88_pci.ko
insmod rtw88_8822c.ko
insmod rtw88_8822ce.ko
4. When run insmod rtw88_8822ce.ko, in most cases, the error will show as below. (few times can work)
Detail error log is attached.
Same step (1) -(4) works very well with kernel 5.4 in same hadrware platform.
