Re: New KRC2 download utility issues

Anybody else having difficulty with this firmware upgrade?

the utility installed correctly
With the DL switch set I can query the KRC2
and get the following response
;KR00;KR73;KRV;KRV KRC2 V1.0;

when I try to upload the firmware I get an error after which time I have
to power cycle the krc2 before it will respond to queries again

KRC failed to reply check KRC2 power, DL switch RS232 cable and com port
;KR00;KR73;KRU;
the KRC2 indicator led flashes about 1 per second

I am running windows 2000 on a fairly modern PC and the com port is a real
hardware one (not a USB adapter)
I have tried with the krc2 powered by the K2 and with the KRC2 powered
directly with no K2 connected.

any Ideas?

Hi Brendan,

A couple of questions:

1. Were you using the new V1.2 download hex files from the web page? If
not, and you were using earlier ones sent out by Jack, they will have
too many records and can cause this error.

(If the earlier hex files, with too many records, were sent by a dumb
terminal program this error was masked since the terminal program does
not look for a handshake response from the KRC2 and always follows the
last regular data record with a termination record that resets the KRC2.)

2. The blinking LED indicates a bad record was received by the KRC2. Did
you try repeating the download after restarting the KRC2?

3. If you restart the KRC2 and query the version number now, what
version do you get?

Re: New KRC2 download utility issues

In reply to this post by Brendan Minish-2

I have two KRC2s, and had similar problem with both. Could not get
either to report fw rev, and when trying to download I would get a "no
response" error. The fw that was in both of them was 1.1D5 .

I used HyperTerm to download, and everything worked fine. On one of the
units I had to put it into download mode manually with the commands.
The other one went right into download mode when I flipped the switch
and power cycled.

Now that I have upgraded them, I can get the download utility to get a
response to the Get F/W Rev. button, but I still get "KRC2 Failed to
reply: " error when trying to download. When I initially press the
Download button, I see the commands sent on the screen, and the KRC2
starts flashing the LED. So it seems like it's ready. Maybe there is a
timeout loop too short? The message comes up pretty quickly.

These are both connected to a Win98 machine with real serial ports.
