No it works fine in 32bit mode. The 64bit mode appears to be slower and so needs a longer default timeout. I'm assuming this placeholder is for all 64bit bugs...

Fair point. I've eight Pi4s here and some may not have the latest EEPROM which could explain the difference. However the problem still holds - can we have a longer...

Well according to this document the default is 20 seconds, which it isn't. But let me try again tomorrow and play with some of these values to see if I...

I didn't say USB boot doesn't work - I said it can time out because some USB hubs have a longer initialisation time than the time the Pi allows. An...

Can't find the exact USB switch I've got as it seems to be discontinued but it's a USB2.0 version of this : https://smile.amazon.co.uk/UGREEN-Sharing-Keyboard-Scanner-Printer-Black/dp/B01N6GD9JO/ref=smi_www_rco2_go_smi_1285150262?_encoding=UTF8&hvadid=309968313994&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9046436&hvnetw=g&hvpone=&hvpos=&hvptwo=&hvqmt=&hvrand=6784479521780918645&hvtargid=pla-350939791158&ie=UTF8&linkCode=df0&psc=1&tag=googshopuk-21 There's hundreds of similar Chinese devices like...

Yes it is. The 2.0 one I have has two USB host leads but also has an On/Off switch for each of the USB devices. The idea was once it...

> You may want to look at network booting (as that'll probably be easier than physically swapping USB sticks), although I've no idea if that works for bare-metal stuff. Good...

Thanks. I went to give those a try but at the moment the monitor is flashing on for under a second then off for 30 seconds. I'll try it again...

I'm booting into the standard Raspberry OS display with the Temple. By "Screen Configuration app" do you mean raspi-config or something else ? Setting raspi-config is definitely being ignored. As...
