Hi!

Trying to upgrade to 9.2.4.

# sh run | inc boot
boot kickstart bootflash:/n3500-uk9-kickstart.6.0.2.A8.9.bin
boot system bootflash:/n3500-uk9.6.0.2.A8.9.bin

# copy tftp://x.x.x.x/n3500-compact.9.2.4.bin bootflash:

boot nxos bootflash:/n3500-compact.9.2.4.bin
boot system bootflash:/n3500-uk9.6.0.2.A8.9.bin

# reload

Forgot to remove old boot command and got stuck in loader:

	loader>
	Booting kickstart image: bootflash:/n3500-compact.9.2.4.bin
	...............................................................................
	...............................................................................
	error: Failed to allocate chunk.
	loader>

Trying to boot from old kickstart image:

	loader> boot bootflash:/n3500-uk9-kickstart.6.0.2.A8.9.bin

Nexus is stuck, need to powercycle...

  - That could point to memory fragmentation , it looks not applicable in this context , but could you also
     try a power cycle of the nexus first ?

Rebooted several times. The Nexus freezes when I try to run boot commands from the loader> prompt.
Tried to boot using the different images on bootflash:, they all freeze

  - Could you try to execute the procedure as explained in : https://www.youtube.com/watch?v=JskVWVY5U00&t=92s
     (of course parameters could change , such as the os version you want to install).

1. Please use the "install all" command to upgrade NXOS instead of changing the boot variable.

2. Please refer to the following documentation to follow the upgrade path: 6.x -> 6.0(2)A8(11b) -> 7.0(3)I7(9) -> 9.3(x).
