DM42 Firmware V3.2 available

[rprosperi]

The update to 3.2 with dm_tool 2.3 was smooth but then I tried to transfer some OFFIMG files and it hung. The DM42 was unresponsive, stuck in USB disk mode, but not anymore recognized by Windows. I had to reset it with a paperclip, then everything worked fine and I was able to transfer the images.

I just had the exact same issue occur; was just coming here to report this and saw Didier's note.

Initially the USB drive connected, then before anything was transferred, it just disconnected (on the PC side - the drive window closed) but the DM42 was frozen in the connected state. The DM42 would not respond to the [EXIT] key. I disconnected the USB cable, and pressed reset with a paperclip. The About screen appeared, and then the DM42 was OK. I then connected again and had no trouble copying files to the USB drive, deleting files on the drive, etc. All seems OK now.

Hi,

thanks for the update...as said already: Its a little bit like christmas each time.

The update via dfu-util 0.9 on GENTOO Linux using Linux kernel 4.14.11 was smooth. No issues so far.

Cheers,
Meino

Same issue here. In my case, after activating the USB drive, it was completely empty. I ejected the drive from Windows, but the EXIT key was unresponsive and required a reset with a paperclip. After disconnecting the USB cable, reconnecting and starting the USB drive, all of the drive's contents were again available.

I still have all the files on my calculator but when I try to activate the USB drive, I get the Windows message:

USB device not recognized
The last USB device you connected to
this computer malfunctioned and
Windows does not recognize it.

Of course I can't see the DM42 in File Manager nor can I add any files to it.


Edit: After rebooting my PC three times, the USB device started showing up again. Linux is looking better and better!

What are the consequences of the lower level of code optimization? Is it slower, larger file sizes, or something else?

Also: what exactly are the before and after optimization settings, and does this apply to compiling Free42, the DM42 OS, or both?

Thanks, updated fine...Nice "31st anniversary of the HP 28C" gift, the HP28C was released 1-05-1987. I bought my HP Prime exactly 1 years ago on 1-05-2017.

I had the same problems as described in this post.
Also a reformat of the usb-disk was again the solution.

Smooth update with DM _tool V2.3 / Windows 10.

Same USB disk issue as reported by Didier and Bob, solved by a reset.
BTW, time/date format and status bar settings will not survive a reset.

Many thanks for the update, though I was not able to hang my beta DM42 with firmware 3.1.

Interesting, my Windows 10, with latest updates, norton security Lenovo laptop has had no USB issues.

Could it be the driver info on the calc being corrupted?
