Issue/Introduction:

This article summarizes an APM-9600 boot failure scenario on XOS 10.0 with a VAP type xslinux_v6_64 VAP

Symptoms:

1. The APM fails to boot permanently with the following output on the console port:
 
DEBUG - LINK [1] - Link Up. 
............. 
DEBUG - HELLO [1] - Received. 
DEBUG - Backplane MAC Address : 0003d2000204.

INFO - Loading network image. 
WARNING - Unable to boot from network.

2. The APM is part of a VAP group configured with the operating system type xslinux_v6_64
 
3. The APM boots normally as a Standby VAP (not part of a VAP group)

Cause:

The APM must run the latest firmware to support the VAP kernel xslinux_v6_64. Here is an example output from /crossbeam/bin/revs_check that shows the missing firmware revision:

Slot  4, PartNo  005682, Serial  P339N000: Bootstrap rev 1.8.0.0, requires rev 1.8.0.2 (ap9600_fpga_0207_flash0005)
Slot  4, PartNo  005682, Serial  P339N000: Bootloader rev 1.8.0.4, requires rev 1.8.0.6 (ap9600_fpga_0207_flash0005)
Slot  4, PartNo  005682, Serial  P339N000: Diag rev 0.5.0.4, requires rev 0.5.0.5 (ap9600_fpga_0207_flash0005)

Resolution:

To perform firmware upgrade, the APM must boot as a part of a VAP group. You can temporarily use a VAP group of the type xslinux_v5_64 to perform the firmware upgrade.

1. Create a new "xslinux_v5_64" VAP group or convert the existing  "v6_64" VAP group into "v5_64".
2. As necessary, modify "available-ap-list" and "max-load-count" to ensure the APM boots the "v5_64" image.
3. Upgrade firmware on the APM module (see XOS Configuration Guide for details).
4. Verify that APM boots the "v6_64" image properly after the upgrade.

NOTE:  There is no application qualified to run on "v6" kernel as of May 2014.
