41CL Flash Update - Sylvain Cote - 08-21-2016 06:47 AM
My little adventure updating my 41CL ...
I have postpone updating my 41CL's (v2:2011, v3:2012 & v4:2015) for years and with the new 1024 registers module from Ángel now seems the right time to do it.
First thing I did was to download and read the excellent how-to manual (Updating the 41CL Flash) from Monte.
Second, I downloaded the 41CL Memory Reference documents of the Manuals section
Third, I downloaded the ROM files from the File Area section.
Then it became complicated and I got a lot more than I bargained for ...
After evaluating my options, I have decided to update my v3 board because if I screw up (a real possibility), I still got the v4 board working.
Next was to find out what was the update gap between 2012 and 2016, which turns out to be almost everything (62 pages or ~500 ROM images).
After that realization, it became clear that I needed to structure myself more seriously.
Starting from the mem_ref.csv file, I have created an Excel file, added new columns and started filling them.
One of the new columns that took the most time to fill-up was the filename and the YCRC validation.
Even thought most of the ROM files was included in the zip files from Monte not all was present.
Also, I wanted to 100% sure that the files I got were valid, so I did the following for all of them (~500) ...
- Match the filename with the ROM description
- If file not found, then upload the ROM image from my v4 board to the PC (if available)
- Calculate the CRC on the PC file to validate the match with the YCRC value of the document
- Using the MLDL2K program, extract the ROM information to fill-up other columns
The results after 30+ hours of work is available here: 41CL_V3+_2016-08-17b.zip.
The zip file contains the following ...
- 41CL_MemoryReference_SylvainCote_20160817b.xlsx (the source file based on mem_ref of 2016-08-17)
- 41CL_MemoryReference_SylvainCote_20160817b.pdf (formatted printout)
- 41CL_MemoryReference_SylvainCote_20160817b.csv (semi-column separated fields of the Excel file)
- 64 folders matching the 64 flash blocks and containing the validated ~500 ROM images
- ROM-INFO.TXT (MLDL2K ROM information for all ~500 modules)
Now that my baseline has been done, my next step is to do the actual update.
I am currently creating a small FOCAL program and a script on the PC to automate the update process.
I will publish them after my update is completed.
Best regards,
Sylvain
PS: Ángel, sorry for the GRAFIKS module validation delay, I never expected to spend so much time on this update.

I've added an anniversary reminder to my calendar to update my own unit each year (at least).
Thanks also for generously sharing your work. Much appreciated.

Yes it can get very laborious when multiple updates are needed... been there myself!
To make it even worse I keep adding new ROM images, like just finished an update to the CLXPREGS plus a new Y-PPC-REGS module; never a dull moment!
