AIR-CAP3602E-E-K9 can not download autonomous IOS image ?!

Hi all.

AIR-CAP3602E can not connect to tftp after format flash. Flash has been erased to free space for autonomous IOS.

When I reset it using mode button , I've got this on the console screen :

IOS Bootloader - Starting system.

flash is writable

FLASH CHIP: Macronix Mirrorbit (00C2)

Xmodem file system is available.

flashfs[0]: 1 files, 1 directories

flashfs[0]: 0 orphaned files, 0 orphaned directories

flashfs[0]: Total bytes: 31997952

flashfs[0]: Bytes used: 1536

flashfs[0]: Bytes available: 31996416

flashfs[0]: flashfs fsck took 11 seconds.

What TFTP server are you using? Try either 3CDeamon or TFTPd32. Also make sure the MD5 has matches for the image you download. This will verify the image is indeed good.
