i20260509 - Character LCD can't be enabled

[ceejayemm]

I installed a new build using i20260509 and applied the latest UPDATE branch (as at 10:00 BST today) on my test system. All seemed well (except #2043 as previously noted). The test installation however is a wired speaker installation so this does not apply in this install.

I have recently acquired a 20x4 LCD display which worked fine on a previous 20260415 build. I installed the same Character LCD on the new test system build and configured System / Displays / Character LCD using Size: 20x4, Character Map: A00, Address: 0x27 and Chip: PCF8574. When I click on OK the system displays 'Character LCD enable ...' in the bottom left hand corner but after a little while this disappears and the Character LCD button is disabled . Nothing appears on the LCD screen and, using 'journalctl -f' whilst the config is in process shows no obvious errors.

I noticed that on the system built with i20260415 and upgraded to 20260509 the config screen shows:

while the i20250509 build shows:

Note the difference in the Address entry, not sure if this the problem.

I also note that the Networks page is showing a problem again:

} ]
}
}

Despite this error, the WiFi config seems to be working correctly.

Network page error now has its own bug report #2102. This bug report title amended accordingly.

@rern

Update 20260529 seems to fix this problem.

Many thanks
