Thank you Michael!
This release, providing "MEMORY CLEAR" instead of "Pr Error" is definitely a very good sign of better "User Experience" VS "100% compatibility".
I am confident to see more in the next releases 😀, and one day maybe the Graal = alpha instrictions vs opcodes 👍
Take care,
Sincèrement, Sincerely, 73,
Boubker

Hi Michael,

Well after continually pressing the Program button on the firmware tool and resetting the calculator, I finally got the calculator update to V32 and get a MEMORY CLEAR. This is not an easy process despite the the very good documentation, or I'm doing something really wrong.

Thanks for the update.

My Voyager DMs are all tricky. Some combination of the program and reset will usually get the update tool to start sending. It varies.
DM10, DM10L: 00031 / DM11, DM11L: 00112 / DM12, DM12L: 02074
DM15, DM15L: 11069 / DM16. DM16L: 02001 / DM41, DM41L: 00859
DM41X: 00036
DM42: 3108

Hello Michael,

Thanks for the new version.
Update via Linux Mint was a breeze.
Have a nice week-end,

I'm having trouble on macOS Big Sur, I installed lpc21isp through Homebrew and it has worked before. It's a DM41L

I used the parameters on the Swissmicro site and it runs without error

sudo lpc21isp -control -controlinv -hex DM41_32.hex /dev/tty.usbserial-0001 115200 12000

lpc21isp version 1.97
File DM41_32.hex:
loaded...
converted to binary format...
image size : 60880
Image size : 60880
Synchronizing (ESC to abort).................................................................................................... no answer on '?'

Nothing indicates on the calculator and pressing reset just resets and doesn't install the new firmware. I also get the same result running lpc21isp without sudo.

I can put the DM41L in serial console mode and can communicate with it using screen/etc.

Thanks

@SteveKennedyUK,
I was able to update my DM15L using MacOS Big Sur today. It was a struggle and took several attempts because of my lack of familiarity with the tools and terminal program. After about the fifth try I was successful and I'm now running DM15_32. I hope you are able to make it work. BTW, one hurdle was putting the DM15 hex file in the root directory. I'm not sure if you did that with your attempt(s). Otherwise the sudo command line was exactly as you showed except for the file name. Also, when I downloaded my hex file from the SM site it went into my download directory as DM15_M1B_32.hex.txt. I don't know why MacOS appends the .txt? I did use the entire file name including the .txt in my sudo command line.

Anyway, I hope this helps.

It's reading the file fine and seems to be transferring and fails to store it on the DM41L
