Hi,

sorry for the delay - haven't been checking here for a few days...

That's strange - if I mount my device I have a directory named 'applications'. That's the one for programs that can be found when you touch the "Applications" symbol on the home screen. In there you find there things like calc.app, dropboxctl.app etc.

There is, however, the folder /system/bin which contains other files with the extension .app. I put vip.app there (as well as vim), but that does not add vim or vip to the applications. Neither does creating the applications-folder and putting vip there.

Any ideas? Do I have to update the list of applications manually?

I'm as astonished as you are - there always has been an 'applications' directory on my PB622 and 623. Is there any chance that you mounted the SD-card instead of the internal memory of the device (and, perhaps at some other time, created a 'system' directory in here)? Sounds a bit unlikely but that's the only idea I have at the moment...

And, out of curiosity: Does an update of the firmware harm your program, once it is installed?

It may happen with some future firmware update if they make incompatible changes to the libraries used by the program. If you have tried installing older programs to be found on the internet you may already have found that some of them don't work (typically ones not written for the PB622/623). That is often due to such a change in the libraries. But this doesn't happen very often, so normally a firmware upgrade doesn't break things.

And if it happens there's the source code, so you can compile (and, if necessary, modify) the program to work with the newer library version;-) In that case also a new SDK would have to be released - the current one seems to be from June 2011, so there were no changes that would break older applications since then.

Best regards, Jens
