I have reflashed a Cisco 9120AXE (I did it before to other APs aswell) with a Cisco EWC-AP Firmware.
Firmware Package: C9800-AP-universalk9.17.09.04a which includes:
>> EWC-Image: C9800-AP-iosxe-wlc.bin
>> AP Image: ap1g7 ( C9115, C9120 )
The "EWC" Part has the IP 172.17.48.8
The "AP" Part has the IP 172.17.50.32
Note: This is the same Hardware which has "2" firmwares - EWC and AP .
Note2: They are in the same subnet 172.17.48.0/20
If I set the TFTP Server to the EWC (172.17.48.8) itself, the Download for its own / embedded AP fails.

--------------
If I change the TFTP Server to my Test-Notebook (172.17.48.217) which holds the needed Images something very strange happens:
The Image for the "embedded" AP starts to download immediatly, as soon as the download finishes the whole AP Reboots with both "sides / parts" (the EWC part and the AP part)

And after successful download the EWC and the EWC-AP are rebooting but still cannot join the EWC-AP to the Controller.
This than happens in a endless loop.... until I make the tftp server unavailable again...
