Updating from 3.3 to 3.10

Post by TomC » Thu Oct 04, 2018 4:56 am

Well, it's been a while and I'm here trying to update my DM42.

Please explain how to do this - when reading the 3.10 update instructions, it is apparent that something substantially changed in the OS and the update process.

I copied files to the root directory, then went to system menu to find that the selection required is not there.

The update process makes reference '...since 3.7, but I find no 3.7 references to study.

Most confusing and frutrating - I would like to avoid wasting another evening...

HELP!

Version 3.3 did not yet include the "Flash from FAT" option so you'll have to do this the old-fashioned way as described here: https://www.swissmicros.com/dm42/doc/dm ... ng_dm_tool

Future updates will be installable using the Flash from FAT option because 3.10 does include it.
Not SwissMicros staff, just an enthusiast.

GRS:

Thank you.

Well, I've updated the driver and the calculator shows that DMCP 3.10 is installed - but NOTHING else.

The calculator is now bricked - I've gone from a working 3.3 to a bricked machine.

When I connect the calc to the PC, the PC chirps like a drive is connected, but it does NOT show in file explorer - thus I cannot copy files to it!!??

I now have lost a usable calculator.

Well, in desperation, I used the flash utility and flashed the 3.10 ...bin file.

...and surprisingly it seems to work.

I did NOT follow the flash from FAT process at all.

Concerned, but at least the machine seems to be alive.

...and even when I activate USB disk mode, it does NOT appear on my PC, even though the driver is installed and 'working properly'.

I'm concerned how to do further updates.

Well, I understand now that I must have to download the combined DMCP and 3.10 software - using the dm_util since the USB disk is not 'visible' yet.

I will proceed later today when time is available.

How do you activate your DM?
I do it this way (and maybe it is an approach you can try, if you have not tried yet):
Calc switched completely off.
Connect USB to calc and PC (I have Win10)
Switch on calc.
Go to Setup, hit "1" and then "3".

Takes about 3 sec. for the PC to recognise the calc and it shows up as Drive "E" on my PC.

Another thought, though; the USB port on the calc is a tad "thick" on the top end, so I have a cable that I've cut away some of the plastic/insulation on the connector, thus get the cable to "reach" a bit farther in, in the port. May that be the issue?

Well I flashed the combined file.

BTW, the only way the PC can 'see' the calculator is if I put the calculator in bootloader mode.

All cabling is fine.

I have 3.10 on the calculator and the PC beeps indicating it is recognizing the USB device, but it does NOT show in file manager.

GRS: HELP!

ps: and there is no Help file

...even though 'About' shows 3.10, the calculator is obviously garbled.

Keying in numbers gives garbled results through the stack.

I've even tried to return to 3.2, but proper directions no longer exist.

I would like my calculator back!!!
