What exactly does the blinking look like? The pattern can tell you what error the cRIO is encountering.
From the
cRIO documentation:

Table 3. Status LED Indications
Number of Flashes Indication
1 The chassis is unconfigured. Use MAX to configure the chassis. Refer
to the Measurement & Automation Explorer Help for information about
configuring the chassis.
2 The chassis has detected an error in its software. This usually occurs
when an attempt to upgrade the software is interrupted. Reinstall
software on the chassis. Refer to the Measurement & Automation
Explorer Help for information about installing software on the chassis.
3 The chassis is in safe mode because the SAFE MODE DIP switch is in
the ON position. Refer to the Configuring DIP Switches section for
information about the Safe Mode DIP switch.
4 The software has crashed twice without rebooting or cycling power
between crashes. This usually occurs when the chassis runs out of
memory. Review your RT VI and check the memory usage. Modify
the VI as necessary to solve the memory usage issue.
Continuous flashing
or solid
The device may be configured for DHCP but unable to get an IP address
because of a problem with the DHCP server. Check the network
connection and try again. If the problem persists, contact National
Instruments.

One thing you could try is to set the IP RESET dip switch to on, and powercycling the cRIO. It should now have the IP 0.0.0.0
From the
cRIO documentation:
Quote:
Push the IP RESET switch to the ON position and reboot the chassis to
reset the IP address to 0.0.0.0. If the chassis is on your local subnet and
the IP RESET switch is in the ON position, the chassis appears in MAX
with IP address 0.0.0.0. You can configure a new IP address for the
chassis in MAX. Refer to the Resetting the Network Configuration of the
cRIO-FRC section for more information about resetting the IP address.
You also can push this switch to the ON position to unlock a chassis that
was previously locked in MAX.

After resetting the IP, try to ping the cRIO. If it responds, see if you can reimage it now.
