Error upgrading from RRF 2.05.1 to RRF 3.01-RC12

[Sytac072]

Hello,
I was trying to install the new RRF 3.01-RC12 on my Duet2Wifi from the actual 2.05.1 but every time I try, I receive an error message on the touch panel which says: ERROR: File 0/sys/Duet2CombinedFirmware.bin is too big and the board restart.

Why does this happen?

You need to Upgrade to 3.0 first before proceeding to 3.01

Now I have another issue... The PanelDue 7i doesn't connect to the duet2Wifi.
It starts, load the page but when I try to push buttons, nothing happens. I have already tried to change the communication speed with some different but was not useful.

Do you have the correct M575 command in config.g, as detailed in the upgrade notes for 3.01-RC12 ?

No, I missed it... Thanks a lot! I will try as soon as I can.

@dc42 I have just reinstalled the firmware and did the correction you told me. Now it works. Thanks a lot!
