Re: Updating from 3.3 to 3.10

This machine has had the driver installed since the ver 2.xx days (beta testing). Upgrades always worked fine until this 3.10 business. I've since re-installed the driver with the same results. I only explained the bootloader vs USB activated modes to describe some of the PC weirdness. The ROOT prob...

Re: Updating from 3.3 to 3.10

No, no exclamation marks appear in Control Panel. I just re-installed the driver.. If I put the DM42 in bootloader mode, it shows up in the control panel as STM32 Bootloader. If I put the DM42 in Activate USB mode, it shows up in the control panel as STM Mass Storage. BUT in either case it never sho...

Re: Mandelbrot graphic test

I too do not get the nicer escape value image.

What are the parameters people are using to get the pretty / properly scaled M-set image?

Thank you

Re: Updating from 3.3 to 3.10

Hello GRS: Thank you for the reply. Since I reflashed the QSPI, screen shows: QSPI SIZE 1370864 CRC: 000cfed6 QSPI READY PGM IFC: 3.9 DMCP IFC:3.9 DMCP IFC COMPATIBLE All seems fine, I've loaded and run programs. I still have to try on the machine that the DM42 did not show up in explorer. Regards, ...

Re: Updating from 3.3 to 3.10

This is the same PC, etc I've been using since the prototype era.

I can try another PC setup, although given that when the DM42 3.10 is installed and appears to run yet gives garbled results in the stack tells me that there is something corrupt at a very low level.

Re: Updating from 3.3 to 3.10

Here again is the latest status: from the DMCP menu, I've formatted and checked the FAT disk. I then got to 'activate USB disk' from the DMCP menu. The PC chirps indicating that the driver is working (and Control Panel shows it installed and working properly). BUT the DM42 does NOT show in file expl...

Re: Updating from 3.3 to 3.10

Oops. I had a flash of optiism there!!!

When using the calculartor and keying in numbers, strange characters appear in the stack.

Keying in numbers and ENTER ing up through the stack, the characters changed.

So obviously, something at a low level is corrupted.

:(

Re: Updating from 3.3 to 3.10

Ok, so I've done the press RESET and PGM to enter bootloader mode. The calc is then recognized the the dmutil (but NOT by file explorer). I flashed the combined 3.10/DM42 pgm. The dm tool reported Erasing, programming, success, Resetting. The calc screen shows for program info: Progaam: DM42 Version...

Re: Updating from 3.3 to 3.10

This is precisely what I have been doing, since the bootloader state is the only mode that the dmutil driver recognizes the calc.

The question is - What .bin file do I flash into the calc? When I do this, the calc does not work.

I will try again and report back with more details.

Thanks,
TomC
