WP34S running here at 34S
Message #1 Posted by Andrés C. Rodríguez (Argentina) on 24 May 2011, 8:44 a.m.

(The latitude of Buenos Aires city is 34S...)

I flashed my 30B with the special cable, an USB to serial converter (FTDI chip), SAM-BA 2.6 (patched) and my Windows 7 32- bit notebook.

It took a bit of trial and error, and some helpful emails (thank you, Katie and Gene!).

The actual download time was about 3 minutes; reasonable for a 126 KBy file at 9600 bps with some protocol overhead. My USB to serial converter has activity LEDs which flashed all the time during the download. A timeout message appeared on the screen, but was duly ignored. Also, at some point, SAM-BA (or its daughter screens) appeared as "not responding", but that was to be ignored too. It's kind of a "patience and faith" test. :-)

When using SAM-BA 2.6, it is obviously important to aim the download to "Flash". The tabs labeled as "SRAM" and "SRAM2" should not be active.

Now I need to improve my understanding of the SVN repository and such, to download the very last ROM image. And I need to print an overlay right now!!

Have you set-up the board correctly? I don't have an SRAM2 tab, at least not on my SAM-BA 2.10 screen. My board setting is at91sam7l128-ek.

Yes, there were no problems with the board. Due to SAM-BA 2.10 not working with Windows 7 and USB converters (mine was just one more confirmation of such incompatibility), I tried with SAM-BA 2.6. This is the one where the SRAM/SRAM2/Flash tabs appeared.

The latest version seems to work while the earlier versions from the last few days are buggy. The writing to flash was badly broken.

From the project site I got a zip file with the calc.bin firmware image that I used last night. It is dated May 11... is there a new version available? How is the SVN system to be used to download the succesive releases?

Excuse me if I'm not asking the right question, perhaps I'm missing something important which was previously discussed.

Buenas tardes, Andrés,

Just go here: http://wp34s.svn.sourceforge.net/viewvc/wp34s/trunk/realbuild/ and download the file calc.bin - that's all.

Thanks for the warning, I was just about to ask if flash writing was broken.

I was also going to ask if something happened to BACK and SKIP, so I will go ahead and do so. Did something happen to BACK and SKIP? They are no longer in the "secret" CPX-h-CPX menu. I thought perhaps iC (increment counter?) replaced them, but get odd looking results when I try it.

I did look around sourceforge for documentation/explanation of the above, but did not find any. My apologies if such data is sitting in plain sight.

BACK & SKIP have been promoted to the program functions catalogue. iC is "internal constant". A List of these can be found in the manual.

The flash commands are on h+STO. PSTO, PRCL and P[<->] have a parameter ranging from 0 to 2. It addresses one of 3 separate regions in flash where a copy of the program area can reside. Backup and restore use region 0 implicitly plus a special region for the data and status.

Start your program with an alpha label before you copy it to flash. This way, it can be directly called from the new label browser found on h+RCL.

A good start may be: 

LBL 'CB'
CL[alpha]
[alpha] CodeBreaker
[alpha]VIEW
STOP
LBL C
...
Once selected from the browser, the program can be easily started with the hot key C.

As I suspected, hiding in plain sight. Well deserved promotions!

Take care! These are the first two commands where user errors will probably happen frequently since you have to take care of the jump width yourself. Maybe we shall print a WARNING in the manual?

Good luck ;-)

SAM-BA 2.10 doesn't work in my environment (Win7, USB). SAM-BA 2.6 do work. Is there a risk to the calculator, or else? I would like to understand why flash writing is "broken"...

Thank you in advance, best regards.

I'm not talking about flashing the image into the calculator but the operations from the I/O menu when it is running (PSTO, SAVE, ...)

Marcus, I just updated to 950... I haven't flashed the real calc yet, but the emulator has a problem: it doesn't save the state. Everytime I run it, it displays "Erased". It didn't happen with previous versions. I also tried deleting the file wp34s.dat, and it gets recreated at next run, but it still shows "Erased" everytime.

Ciao Christian,

Thanks for your observation. This is a bug definitively :-/

wp34s.dat will be created the first time time you start the emulator and should be updated every time you resume it.

We'll get that repaired.

Can you try again with 955, please?

34° 35' 15" S, according to one reference. Quite a remarkable coincidence!

BTW, according to Google Earth I live exactly 25 meters southwards from 25° 25' 25.00" S. Time to get myself a 25C ? :-)

Maybe Paul, Walter and Marcus will produce a 25s next. ;-)

I've mentioned a 43s. No 25s yet.

A 25s isn't on the radar at the moment. It would be straightforward to emulate or replicate the 25c on the 20b/30b hardware.
