I try to 20sec reset and tftp a firmware.Not work. But it can boot form TFTP when use command "bootipq tftp".  Then it can work normally with WLC. It will appear the same problem when restart it.

Is it a software or hardware problem?

Thanks.

I'd guess faulty flash but not sure if COS AP's have an option to do fsck to make sure it's not just flash corruption.
Otherwise TAC case and probably RMA - TAC will tell you if it's something that can be fixed without replacing the hardware.

looks like it cannot find a valid image in flash, but can if you manually boot from tftp server

then the image is run from RAM instead of flash.

you can try from the WLC to perform a preload of the primary or backup image on flash (as if this is an upgrade).

if this fails than I suspect  the flash is faulty and you need to RMA.

I guess this went wrong:

• To reset the AP to its default factory-shipped configuration, keep the mode button pressed for less than 20 seconds. The AP's configuration files are cleared.

This resets all configuration settings to factory defaults, including passwords, WEP keys, the IP address, and the SSID. However, the regulatory domain provisioning is not reset.

• To clear the AP’s internal storage, including all configuration files and the regulatory domain configuration, keep the mode button pressed for more than 20 seconds, but less than 60 seconds.

you held the button too long and "cleared the AP's internal storage" wich could read as "erased the  flash"!
