roving wifly RN-131C *ERR WATCHDOG*

I’ve a Roving Networks wifly RN-131C ver 2.21 and when turned on reboots from time to time and prints ERR WATCHDOG. A typical session:

WiFly Ver 2.21, 07-11-2010

MAC Addr=00:06:66:13:cc:35

Auto-Assoc roving1 chan=0 mode=NONE FAILED

READY

ERR WATCHDOGWiFly Ver 2.21, 07-11-2010

MAC Addr=00:06:66:13:cc:35

Auto-Assoc roving1 chan=0 mode=NONE FAILED

ERR WATCHDOGCMD

<2.21>

When I try to upgrade I get:

<2.21> get dns backup

DNS=87.216.1.65

Name=server1

Backup=backup2

<2.21> get ftp address

FTP=208.109.78.34:21

File=wifly-GSX.img

User=roving

Pass=Pass123

<2.21> ftp update

<2.21> FTP connecting to 208.109.78.34

FTP timeout=2

If I change to rn.microchip.com server:

<2.21> set ftp address 198.175.253.161

AOK

<2.21> get ftp address

FTP=198.175.253.161:21

File=wifly-GSX.img

User=roving

Pass=Pass123

<2.21> ftp update

<2.21> FTP connecting to 198.175.253.161

FTP timeout=8

That is, I cannot upgrade and don’t know how to get rid of rebooting and ERR WATCHDOG messages. Any ideas?

Solved. The protoboard was faulty. Poor contacts cause this kind of errors. Could succesfully upgrade to lastest firmware version 4.41
