Problem building calc.bin?


I can flash my WP34s with calc.bin downloaded from sourceforge reliably, but I cannot flash an image if I build it myself. I run flash.cmd and the log file indicates the build was successful. The error I get from the flash programmer is "no answer to packet xx." That's not an exact quote; I'm not at the right computer now, but it's pretty close. xx is not always the same number. Has anyone seen this or know what I have wrong?


Check the size of the file! I assume that your compiler does not produce the same output as mine. The file size must not exceed 128 KB. Has the post processing step been successfully executed? It takes the file calc.tmp, strips off a part that contains the original 4 byte jump addresses in the command tables and replaces the dummy entries by 2 byte equivalents of the original addresses. The resulting file should then be shorter then 128 KB. Without this step the binary will not work.



Thanks for the quick reply. Yes, the file is less than 128k. It appears the post processing completed. Below is a cut & paste of the end of the flash-build.log, in case it provides a clue.

I am using an older XP machine with a native serial port, no USB-to-serial adapter.

Which "flash programmer" do you use? There are 3 of them.


Not MySamba or Samba, but the one from the flash directory on sourceforge. It only fails using my builds and never using builds I download.


If its name is WP34sFlash, it is the new one and still in beta.

You should try with MySamba. If you still have the problem, then it comes from your build. If not, from WP34sFlash and then, I would very much like to get one of you calc.bin file to try to reproduce it.

Yes, I was using WP34sFlash. I will try MySamba and let you know the resuly, although it may be a couple days before I get back to that XP machine with native serial port. If MySamba works, I will get a copy of my build to you.



I tried flashing my calc.bin file using MySamba and it works. Unfortunately, I made another change at the same time so I don't know which change made the difference. I also added the crystal mod. The next time I flash, I will go back to WP34sFlash and see if that works now. The only issue I see now is that when I flash with my version of calc_xtal_full.bin, I don't seem to have the "full" capability. The file size seems correct - very close to the release version of calc_xtal_full.bin. Crystal functionality seems to work, I can run the stopwatch, etc.


Ed, send me the contents of your realbuild directory and I can check it out.


Ed, the log looks perfect.
