Problem starting cpmish from an NC200

[wilco2009]

Hello, First of all I would like to thank you for your work, it looks great, unfortunately I am not able to make it work on my NC200.
After formatting a 720KB disk from the NC200, I dumped the nc200.img file with dd with the following command on an Ubuntu OS:
dd if=nc200.img of=/dev/sdb
(sdb is my USB floppy)
I have extracted the image and compared it with the original file and they are identical.
I inserted the floppy in the NC200 disk drive and pressed FUNCTION+R.
The system starts reading from the floppy and displays the message: "Preparing Memory"
But after a few seconds reading the disk it returns to the main menu.
Would you have an idea what the problem could be?

Any help would be well received.

NOTE: I do not have a flash card inserted, but I understand that it is not essential to boot the system.

Hello --- that should absolutely work. Returning to the main menu is the normal behaviour when the system crashes so I suspect it's got through the boot loader and then something's gone wrong.

Unfortunately the floppy drive of my own NC200 has died so I haven't been able to touch this for a while. It's possible there's been a regression caused by other cpmish work. If so it's likely to be something very simple, but I can't debug it myself.

Did you build the image yourself or use the downloadable binary?

Thanks for answering. I downloaded the image already built.
Unfortunately my floppy drive has died again, so I won't be able to do more research on the subject.
Thank you very much too.

@wilco2009 I had exact the same Problem. My Floppy drive suddenly could not format floppy disks (Error on Track 80) and could not boot CP/Mish from the floppy.

I disassembled it, used compressed air to "clean" it an put some WD40 on the moving part of the Citizen Floppy. (Red circle in the pic)
No to much, just lubricate it. And it worked again like a charm.
