Problems using the Serial Bootstrap monitor

[BillC]

Hi, I have managed to brick my SB700EX when downloading a new program version using autoupdate.

I can boot the SB700EX using the serial monitor, and it recognizes the command 'A', and responds with 'HELP for help' and an 'nb>' prompt. However it only waits for about 4 seconds before restarting, this does not give enough time to enter the 'FLA' command and start the file transfer.

I have changed the setup boot wait time (option 7) to 255 seconds and saved it OK, but it has not made any difference, it still reboots about 4 seconds after the A and its prompt.

the monitor says it is "SB700EX Monitor V1.03 Feb 28 2011 10:32:22"

Any help would be appreciated,

Thanks, Bill

Is the watchdog turned on? Does it do this after a full power cycle?

Thanks for the prompt reply Pbreed, you got it first time. The watchdog was enabled, I use it to recover if my program bombs, disabling the watchdog fixed the problem.

I will re-enable it once I have finished debugging.

Many thanks for your help.
