Raspberry Pi USB boot ......

I have Raspberry Pi set for USB priority boot .
Using the RISC image from IMAGER ….
The RPi boots but I get the terminal screen with :
,
No keyboard present-autobooting
Supervisor
’

Works OK if I put the same image on SD card ….. ??

The standard image is designed to boot from SD card, and needs a few modifications to boot from USB. The process is explained here.

Thank You ….. Not simply it appears .
It is such a shame that RISC didn’t evolve
along with the RPi …. I would love to
know the history of that whole development .

The standard setting in the file CMOS is for the boot filesystem to be SDFS. CMOS used to be in non volatile RAM. If you type the following commands:

*configure filesystem SCSI
*saveCMOS SCSI::0.$.CMOS

Alternatively type

*run scsi::0.$.!Boot

Some magic in the module SDCMOS updates the file CMOS on the SD card whenever settings are changed

>> *configure filesystem SCSI
>> *saveCMOS SCSI::0.$.CMOS

What do I need to open that folder ?
MousePad gives non-utf ??? error

>> *run scsi::0.$.!Boot
keyboard is set wrong at that point

MousePad gives non-utf ??? error

The commands required to make a USB SCSI installation work should be added from within RISC OS.

“No keyboard present-autobooting” is mis-leading, no USB keyboard was found at an earlier part of the start up but it should now be working at the Supervisor prompt. If the keyboard is not doing anything at all then the keyboard may be incompatible. The only option is to try something else. I can type at that Supervisor prompt on a newly imaged RISC OS on a USB memory stick

The keyboard works, but set for wrong language …. U.K…???
AND
For some reason this forum will not keep my e-mail – password ….
I have to ’ change password ’ each time I want to post ?

Which would mean it was on the system default, have you used the Configure Keyboard to set a different keyboard?
Mouse Menu button over the switcher icon – select Configure in the resultant menu and then select Keyboard.

How can I Configure Keyboard without booting up ?

How can I Configure Keyboard without booting up

I’m going to assume that you mean without booting into the desktop. If you truly have no keyboard being recognised then you have an incompatible keyboard as David said earlier, in which case, use a keyboard with less in the way of fancy keys, glide pads and bells/whistles and thus less current draw etc.

Basically:
Type in

 *keyboard UK 

If I type " Keyboard "

I get " 2eyb6ard "

2eyb6ard

Turn off Num Lock on the keyboard.

To make that permanent, on the USB device, the setting needs to be saved to the CMOS file as previously described. (RISC OS on an SD card would automatically save its CMOS to the card.)

*Configure NoNum

NoNum documentation is here.
