Press the ESC button during AP startup to enter ROMMON mode. Then use the following command to upgrade the IOS AP.
ap: ether_init
ap: flash_init
ap: tftp_init
ap: set IP_ADDR
ap: set NETMASK
ap: set DEFAULT_ROUTER
ap: tar -xtract tftp://< server ip address >/< image name > flash:
ap: boot flash:/< image dir >/< image name >
The following is the upgrade process, I used an AIR-CAP3602I-A-K9.
1. Set the IP address
ap: set IP_ADDR 10.106.32.40
ap: set NETMASK 255.255.255.0
ap: set DEFAULT_ROUTER 10.106.32.1
2. Initialize TFTP and Ethernet
ap: ether_init
Initializing ethernet port 0…
Ethernet speed is 1000 Mb – FULL Duplex
ap: tftp_init
tftp_init success: You can now use tftp file system!
ap: flash_init
Initializing Flash…
…The flash is already initialized.
3. Load image
ap: tar -xtract tftp://10.76.76.160/haifengli/image/ap3g2-k9w8-tar.153-3.JF10.tar flash:
DPAA Set for Independent Mode
tide_boot_speed = 1000
DPAA_INIT = 0x0

extracting ap3g2-k9w8-mx.153-3.JF10/ap3g2-bl-2600 (190140 bytes)…………………………………..
4. Boot from new image
We can use the dir command to confirm the directory and filename in the flash before starting with the boot command. I deleted some content here.
ap: dir flash:
Directory of flash:/
28 -rwx 291 <date> info
126 drwx 2496 <date> ap3g2-k9w8-mx.153-3.JF10
ap: dir flash:/ap3g2-k9w8-mx.153-3.JF10
Directory of flash:/ap3g2-k9w8-mx.153-3.JF10/
127 -rwx 230262 <date> ap3g2-k9w8-mx.153-3.JF10
128 -rwx 73 <date> ap3g2-k9w8-tx.153-3.JF10
129 -rwx 190140 <date> ap3g2-bl-2600
ap: boot flash:/ap3g2-k9w8-mx.153-3.JF10/ap3g2-k9w8-mx.153-3.JF10/
Rebooting system to reset DPAA…
IOS Bootloader – Starting system.
flash is writable
FLASH CHIP: Numonyx Mirrorbit (0089)
Xmodem file system is available.
flashfs[0]: 127 files, 15 directories</date></date></date></date></date>
Another way is to use the following command.
ap: set BOOT flash:/< image dir >/< image name >
ap: boot
