It is best to follow that path if you want to be sure of success but sometimes it might work upgrading directly but it's a bit of a gamble. Always refer to the release notes but they rarely cover very old versions (and Cisco don't test that, so it's best to do it in stages to ensure success.

I guess you mean it's now running 8.10.130.0 after u-boot recovery?
The command to install next version (8.10.190.0) is:
AP#archive download-sw /reload tftp://172.19.96.10/ap1g7-k9w8-tar.153-3.JK10.tar

- Looks to me that the EWC conversion (loading C9800-AP-iosxe-wlc.bin) did not succeed ? For starters is that what you want : concerting to EWC ?

What I want is IOS update.
It has been converted to EWC mode.
The problem is that we can't turn it from ROMMON to the previous version of IOS or update it.
I don't know how to give the AP an IP when I'm in ROMMON even though I'm trying to update the IOS
The TFTP server consists of a laptop.

- I am not sure if your EWC conversion was correctly executed because of :

I'm trying to reattempt the IOS upgrade by referring to this document, can I know the command to override the IOS with AP on the TFTP server in ROMMON mode?
The copy command is not used.

- The mentioned document does not need or mention ROMMON ; instead network parameters to get the recovery image are set in the u-boot> prompt ,

Thank you marce!
Thanks to you, the boot was successful!
But I don't know how to upgrade the IOS in the future...

You don't mention what model of AP you are working with but since you are referring to the u-boot recovery guide I assume it is one of the C91xx APs which run AP-COS (ClickOS) not IOS. This means they do not have ROMMON - only u-boot. If you follow the instructions in that guide exactly (I have done it, as have many others, and it works) then the AP will be restored to a 8.10.130.0 CAPWAP image. You should then upgrade it to a 8.10.190.0 (15.3.3-JK10) CAPWAP image, then upgrade to 17.6.6 CAPWAP image (15.3.3-JPK7) and then convert to EWC using the EWC software images.

hello Rich R
After reading the document yesterday
u-boot>reset
The command was issued and the boot was successful.
As you said, do I have to upgrade it sequentially in three ways?
8.10.130.0 --> 8.10.190.0 --> 17.6.6 CAPWAP --> EWC images?
Do you need a total of 3 upgrades?
I tried to convert it to EWC image 17.09.04a at once and failed. Do I have to go through that procedure?
Previously, I tried to convert from 16.12.4a to 17.09.04a, but I failed, so I downloaded a new boot image from u-boot and accessed it, but I'm confused.

hello Rich
I prepared the necessary IOS as you said. It's version 8.10.13.0 now.
AP-type capwap tftp://172.19.96.10 command won't work, any command or reference document?
