Question: If the CPS is aware of the size of the flash chip, why would it only backup 1MB and not all 16MB?
Which version of the cps are you using ?

Not which firmware
I just checked and my 8Mb is being backed up OK.

I don't have a radio with 16M so can't test that

Its possible the 16Mb support was not in the version from 02 / 11 /2021, as only Daniel had a 16Mb radio

Do you know what ID code your chip uses

The firmware and cps expects 0x4018

if your chip does not reply with that device indentifier it won't be recognised as 16M by the firmware or the cps

The original flash chip shows SPI ID:EF4014
The new flash chip shows SPI ID:EF7018

Does that sound like the ID code you are referring to?

That device ID 7018 is not currently supported.

What manufacturer is that chip made by. The code does not seem to be a Winbond device.
Even if we changed the firmware to accept 7018 as a valid chip code, it may not work because the commands may be different because its not a Winbond device.

Edit.

I checked Digikey for the part number you quoted in an earlier post,

https://www.digikey.com/en/products/det ... IG/3008697

and its definietly supposted to be a Winbond device

However, if you look in the Winbond data sheet, the code should be 4018

https://www.winbond.com/resource-files/ ... %20kms.pdf

So your chip is probably a clone or fake winbond, not a real one

Actually it is a Winbond device. It's a 25Q128FVSG chip.

Well, that figures. What's the ID code of the original flash chip?
