I've uploaded ROMs to CL RAM in the past, so I recognized the overrun error right away. I remember a post you made about a year ago that must have been the genesis of this automated utility. Clupdate really takes the bookkeeping and manual interaction out of the daunting update task. Updating a CL by hand would no doubt take twice as long and subject to error at each point of interaction. Great contribution!

Since I'm sure every CL owner will use this in the future, one suggestion for saving time would be to use the --diff results from comparing two rom files to drive the update process. I plan to keep the last rom update file used so I know the state of CL flash. This would be an even bigger time saver with the upcoming v5 model.

BTW, if you do end up with a GUI front end with file chooser, I'll have one more reason to retire CLWriter...

Mark - you can also use the FDBVER? and/or IDBVER? commands in the Update ROM to display the date-stamp of the ROM set currently installed in flash, rather than keeping notes, etc.

Of course, you also should keep the prior ROM set, in order to easily generate the --diff report. The scan process can generate the equivalent information for you, but if you know the changed pages from the --diff command, it is *much* faster to update with the manual commands also in this new ROM.

RE: How to Update 41-CL
Just slightly off-topic, is there actually a 41CL emulator? I'm not sure if I've ever seen one—not that my experience is particularly wide-ranging. I would have loved to have a tinker with some of the functions made available in the machine.

There is no 41CL emulator, however that's not really an issue as the 41CL is effectively 'only' a 41CX which is much faster and can use any 41 ROM. Speed and ROM installation would need to be different in an emulator anyhow, so there is no reason to justify making such an emulator. Almost all 41CL-unique functions are related to managing things like ROM/memory configuration, speed, serial port, etc. (41CL configuration management controls) so aren't of much general use for user programs.

There are many 41 emulators on virtually all platforms, and most of these can perform about the same features as a 41CL (i.e. faster, use all ROMs, etc.), however I recommend you get/make a 41CL - any real '41 fan prefer the real thing over an emulator.

nsimII has built-in support for the 41CL but I've not tried it.

Thanks Didier, I have not seen this before. I obviously should have started with "Not that I know of...".

I am curious about and would like to hear feedback from anyone that has run 41CL on this emulator pkg; if you've done so, please add some comments.

Another V2 41CL updated
I went through the procedure to update my v2 unit today using a Suse Leap 42.2 Linux host. 63 images were out of date. It took approximately 3 hours to complete, with an interruption due to a TIMEOUT reported by the 41CL just over half way through. Could have completed sooner if I knew how to restart part way through without reading the presentation. Used a fresh set of batteries, didn't run them all the way down.

Thanks Monte and Sylvain for your hard work!

Normal procedure using high level functions
Code:
CMOPEN    // open communication channel "*" FLCHK?    // verify all flash memory from 0x000 to 0x0FF/0x1FF against flash database "*" FLUPD     // update all outdated Flash pages marked in CFLDB located at physical RAM page 0x806000 CMCLOSE   // close communication channel and end java program

Assuming FLCHK? completed successfully, but FLUPD did not. Java program must still be running, if not, restart it. To resume, do the following ...
Code:
CMOPEN    // open communication channel CDBEXP    // export CFLDB located at physical RAM page 0x806000 to the PC "*" FLUPD     // update all outdated Flash pages marked in CFLDB located at physical RAM page 0x806000 CMCLOSE   // close communication channel and end java program

I had one TIMEOUT during the update process, as well (I wasn't paying attention and my Mac went to sleep). Not knowing any better, I checked to see if the '*' was still there, and I simply executed FLUPD again.

Thanks again, Sylvain and Monte!
