How to update FW of Wipy 1.0

I have found 2 pcs of WIPY 1.0 in the drawer and I would like to use them for my small project.
I wanted to update their firmware and I did all the needed steps... put the newest mcuimg.bin into flash/sys directory with help of FileZilla... no error messages but there was no update of FW... after reset I see always the same versions of MP which were flashed sometime in the history, see pictures.

Have I forgotten how to upgrade these old Wipy or I miss some information?
Could someone help me to find the lost way?

No, looks ok. The image path is defined as /flash/sys/mcuimg.bin, so I do not know whther the leading / makes a difference.
from the code:

Code: Select all

#define UPDATER_IMG_PATH "/flash/sys/mcuimg.bin"

@Roberthh Thank you for confirming that my procedure was correct.
FYI... I did all the steps with FileZilla on a Linux PC and therefore I tried the same with FileZilla on a Windows PC… and to my surprise, everything was successful at the first try ... I probably will have to look at the installation of FileZilla on a Linux PC.
I would have one more question. I have discovered here that the last release has bootloader.bin in Do you know if it is necessary to install it and how?

I did not know (or forgot) the WIPy repository you mentioned. Anyhow, the latest binaroes are at Obviously the device needs a bootloader, and I faintly remember to upload firmware by wire. Must be somewhere in the documentation. In the micropython docs there is also a note about the bootloader:
The bootloader.bin found inside is there only for reference, it’s not needed for the Over The Air update.
