Don,

How do I know if I have a ZX-24 or a ZX-24a? I want to get the proper firmware.

Vic,

If you are using the ZBasic IDE, one method you could use is to choose Options - Device Options - Identify Device.

Jack,

Worked for me. Thanks! I didn't even know that was there.

In addition to the method that Jack mentioned, you can also tell which device you have if you can read the AVR processor type (mega32 or mega644) on the chip. Often, however, that legend is obscured by the crystal.

The ZX-24a also has a yellow dot on the mega644 chip at the "pin 1" marker while the ZX-24 does not. You can see this difference in these two images: ZX-24, ZX-24a.

Don,

The device is a ZX-24 (no yellow dot).

A problem updating the firmware. Confirmed that the device was a ZX-24 NOT a ZX-24A. I downloaded the file for the -24 and attempted a normal upgrade which failed after four or five dots. I did not note the error message.

I then attempted an emergency update which failed with the message "Device failed to respond to ATN signal on COM1" I tried several times always getting this same message. Have I destroyed my -24 or is there something else I can do to attempt a recovery?

Any enlightenment will be appreciated.

Vic

Were you attempting the update using the IDE or the zload utility?

There was a problem reported recently with the zload utility where the firmware update process was waiting for an ATN response in emergency mode. However, the ZX doesn't send an ATN response when it is wired for emergency update mode. The zload utility in the new installer (zload v1.2.3) corrects this problem.

In any event, we're happy to replace the ZX if you have trouble updating it.

I was using the IDE. Anything I can do?

You can try the emergency update using the zload utility. It can be found in the installation directory, typically /Program Files/ZBasic. If you're using COM2, the invocation syntax for emergency update would be:

Code: Select all

zload -c2 -e zx24a_2-3-0.zvm

Of course, you need to wire up the ZX-24a for emergency update as described in section 7.1.1 of the ZBasic Reference Manual before you issue this command.

Don,

Code:
zload -c2 -e zx24a_2-3-0.zvm

I assume you meant:

Code: Select all

zload -c2 -e zx24_2-3-0.zvm

I'll give it a try. Thanks!
