So, you have a directory called "Documents" in the root directory of your filesystem, right?
If not, should the path not be ~/Documents/DM41L/DM41_28.hex (note the tilde before the first slash, it denotes your $HOME directory)?

Re: Firmware V28 for DM1x/DM41(L) units
Hello Lance,
Yesterday, I have successfully updated all my DM1X/DM4X calculators (11 units) with a MacBook Pro 17 running macOS 10.13.6.
Try grsbanks suggestion, I am pretty sure that is the problem.
If it is still not working, come back here and I will help you with this.
Best regards,
Sylvain

I also had no trouble upgrading My DM15 and DM41L to v28 - using Linux.
The firmware downloaded from the website is OK.

I did forget the tilde when I posted my reply yesterday, but did use it in the terminal - forgot to type it in my post . But, the problem is solved - I downloaded DM41_28.hex using Chrome as opposed to Safari (which I was using yesterday). I then ran the terminal command to upgrade the calculator and all went smoothly. I don't have the skills to say why, but Chrome saved the file as DM41_28.hex and not DM41_28.hex.txt and this appeared to make the difference.
Thanks to everyone for their help/suggestions!

Great!

FYI: I have downloaded the files with Safari, then renamed the files from DM??_28.hex.txt to DM??_28.hex which I then used to do the firmware upgrade.

Re: Firmware V28 for DM1x/DM41(L) units
Hello everybody,
I am unable to update Firmware V28 using either Linux/Windows/Mac on my DM41L.
Linux : nothing happens, it seems to run and gives me the answer at the end of the process "no answer on ?"
Windows : run on my Linux machine with VMware, so I will not fight to much (Port 1, file name selected and program clicked but nothing happens).
Mac : does not want to install lpc21isp (MacPorts is installed and ok)
sudo port install lpc21isp
Password:
---> Building lpc21isp
Error: Failed to build lpc21isp: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_cross_lpc21isp/lpc21isp/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port lpc21isp failed
(DM41L being of, reset pressed when asked for)
Any Clue ?
It is the first time I do the operation on my DM41L.
Thanks a lot
Patrick

Re: Firmware V28 for DM1x/DM41(L) units
I see that same error on MacOS, Patrick. It seems to be broken in Mojave.
I was able to do the upgrade on Linux. This is just a guess, but perhaps you didn't use the outer most hole on the back of the calculator to do the reset? And, in the past, I've had to try the reset a couple of times before the computer noticed...

I did use the reset hole by the corner, not the program (PGM) one.
Thanks for you help.
If Linux would work, it would be fine.

If someone says It works, I tend to believe him. Ok for Mojave, I won't try anymore.
For Linux, I was waiting too long (yes my machine is very fast).
I typed the command line and quickly pressed the reset and that's fine : V28 is installed.
Thanks again.

Re: Firmware V28 for DM1x/DM41(L) units
I just updated my DM15 again. Here the problems I encountered.
I find Linux 4.X very convenient. Hardware driver is already in the kernel. It just works if you have the lpc21isp installed.
But it did not work first. I thought then that I needed the driver like on a Mac or Windows.
But I just forgot to press the reset-button at the "Synchronizing..." moment.
I put a reminder in my script for the next time
What happens also on my Linux distribution, is that the device name changes after each new connection made with lpc21isp, but the older one does not give you any warning or error it just don't work anymore.
So the default device for my DM15 was /dev/ttyUSB0 but later the console wanted /dev/ttyUSB1 and the DM41 /dev/ttyUSB2 but its console for changing the time wanted /dev/ttyUSB1 again. Had to check always.
What is also important to use fresh batteries for the calculator upgrade. The calculator may work but not the connection.
You can also use the lpc21isp as a console for the serial console mode instead of "screen" "cu" or whatever, as a check if the connection will work:
lpc21isp -termonly /dev/ttyUSB0 38400 12000
lpc21isp version 1.97
Terminal started (press Escape to abort)
DM15_M1B turned on
DM15_M1B ready
