App not running anymore...

[dl9sec]

Hi,

I don't know why, but since one of my last updates of the Flipper FW (RM current), the app doesn't run anymore.
I updated the flipperzero-rs stuff and rebuilt the app, but I get the following error message:

Error
Load failed
Tools/waveshare.fap
Update Firmware to use with - this Application (MissingI-mports)

As far as I see, the current RM FW is at API 39.2 which didn't change since versions.

What am I doing wrong?
Can I configure the apps sourceode somewhere to fit to the RM FW??

Thank you in advance.

Regards, Thorsten

Thanks for reporting. I haven't used my flipper zero in awhile and, unfortunately, I don't have much free time right now to dig into this issue.

It does seem like an issue with a missing API. Maybe the verbose logging option in the flipper zero firmware will print out which function is missing?

Hi Michael,

thank you for this very valuable hint with the serial logging.
Here is the output:

525438 [I][Loader] Loading /ext/apps/Tools/waveshare.fap
525865 [W][ApiHashtable] Can't find symbol with hash 863c9b49 @ 080A0C84!

525935 [E][Loader] Status [3]: Load failed, /ext/apps/Tools/waveshare.fap: Update Firmware to use with this Application (MissingImports)

Yes, seems, that there is something missing...
Does this help in any way?

I updated the flipperzero-rs to the latest version (git pull) because I saw, that there were some changes concerning the API and tried to build the waveshare.fap again.
There seems to be bigger changes now. I got the following errors:

Seems, that the code is broken with the latest flipperzero-rs :-(

Hi Michael,

I tried to fix the errors step by step, but aleady struggled with the second error.
The NFC API seems to be completely different now.
Unfortunately I don't even know Rust, nor this flipperzero programming model, so I am stuck for now... :-(
