My adalm2000 has LED1 blinking twice a second. Is this the normal condition?

would like someone to help with firmware update 0.33, currently 0.25

There are instructions on this site.  Read the user infornation for details.  Download the updated firmware, unzip it, copy all to the ADALM USB file system, unmount ADALM USB drive but do not disconnect USB cable from computer.  It starts the update by itself, one of the lights blinks rapidly until update is done.

No one answered my question yet, bummer.

The rapid blinking of LED1 indicates that the device is in programming mode. Since you mentioned that everything is working fine, this behavior is normal. For peace of mind, you may try reflashing the firmware by following this guide: ADALM2000 (M2K) Firmware Updates [Analog Devices Wiki]

Okay, thanks Rey.

It is not blinking rapidly as in programming mode.

Just twice a second.  But I think I will try a reflash anyway.
