SERIOUS PROBLEM WITH THE 41CL ***SOLVED*** - yann - 03-27-2024 09:12 AM
Hi, I just updated the 41CL to the new rom_files_240325.zip.
The entire update did not cause any kind of problems.
I upgrade using the 9PRG MMU, which contains the YUPS module.
Once the update is finished, I try to go back to my 9CFA:
I run XEQ MMUDIS
The "terrible answer" I get is NON EXISTENT.
I think the update had a problem and I run XEQ YRES,
hoping to get a basic system, but as soon as I try to install YFNX, here is the real "cold shower":
the answer I get is NO IMDB!!!
How can I solve this problem?
Thank you very much!

How are you installing YFNX, with PLUG1U? Did you try an MMU clear?
from my notes:
Code:
XEQ YRES # disable MMU; from TMOD
XEQ MMU? # ensure MMU is disabled; if not, try backspace-ON and repeat
XEQ MMUCLR # initialise MMU registers in RAM
"YFNX" XEQ PLUG1U # plug YFNX to port 1 upper, page 9
XEQ MMUEN # enable MMU
XEG PLUG
?IMG ? # check ROM page layout; should show: YFNX 9RE: SERIOUS PROBLEM WITH THE 41CL - Sylvain Cote - 03-27-2024 11:34 PM

It seems that there is a problem with the latest IMDB.ROM file, I will post a workaround soon.

Hello Yann,
The following procedure will downgrade your 41CL to the 2024-03-05 package.
- 41CL Calculator Manual, section "Plug into Port/Unplug from Port Functions" (p.24 to p29) describe how to map a ROM image with its page address
- 41CL Memory Reference allow you to map the IMDB ID to/from its Flash page address
- download the previous archive file: rom_files_240305.zip
- plug the serial port between the 41CL and your computer
- start the clupdate program with the previous archive file (rom_files_240305.zip)
- 41CL: configure without IMDB
Code:
MMUDIS
MMUCLR
"00A-RAM" // YFNX address in Flash
PLUG1L
"062-RAM" // YUPS address in Flash
PLUG1U
MMUEN
CAT 2 // ... "-YFNX 4C" ... "UPDAT 4D" ... - 41CL: downgrade
Code:
CMOPEN
CPONLY
"*"
FLCHK?
FLUPD
CDBEXP // update list should be empty
CMCLOSE - 41CL: validation & cleanup
Code:
FDBVER? // 03/05/2024
CDBDEL
MMUDIS
MMUCLR - PLUG functions should now works with IMDB names

I just uploaded a revised rom_files_240325.zip with IMDB.ROM and IMDB_V2.ROM repaired. It "should" be okay now. Sorry about that. It has been a while since I edited the image database and I accidentally made a bad edit.

Many thanks for your help. Everything went well.
Only little problem, I didn't find the CDEXP instruction, but the CDBEXP instruction and I used it.
Unfortunately in an attempt to solve the problem, before asking you for help, I sent the 41CL to memory clear, so now I have to reinstall everything! But I'm happy to see that even problems that seem difficult to solve are solved quite easily on 41CL!!!
With best regards.
