Hi
Trying to do firmware upgrade to my zx24p but get: File zload zx24p_3-03.zvm does not contain a proper download image . Is it correct to do like this for upgrading ?
-right click on file -> save as
- image file in same directory as zload.exe
- in command window : zload zx24p_3-03.zvm (COM1 as serial port)

Any suggestions would be appreciated
Regards Håkan

The command you've shown is for downloading ZX programs (.zxb extension) not VM update files. You need to use the -u or -e option for (normal or emergency, respectively) firmware update.

You can also use the IDE to perform a firmware update. From the Options menu, choose "Device Options" and then use the controls in the uppermost group box.

Note, particularly, that the emergency update mode requires some special connections on the ZX device. This mode only needs to be used if the "normal" firmware update fails for some reason leaving the device unable to be updated by the normal means.

It is very important to provide clean continuous power to the ZX device and to avoid resetting it or otherwise interfering with the update process.

All of the above information can be found in Section 7.6 Updating Device Firmware and Section 9.1 Firmware Updates of the ZBasic Language Reference Manual.

Thank's
I missed the -u command when reading the manual the first time. Somethimes you get blind when reading
