Thanks, that's what I have also found thanks to critor's tests.

Well.. the repositories did.  You have to build it from source, and it's currently not stable (works for many programs, but crashes on others, and some keys are scrambled).  Still, I'm too amazed at the alacrity of the developers.

A major update is available. It includes:

- Many functions of the standard library, that will hopefully help to port existing programs. The documentation on Hackspire is up-to-date.
  (freopen, errno, toupper, strtod , strtol, strspn, strerror, strcat, strstr, fflush,  remove, ungetc, stdin, stdout, stderr, feof, rewind, strcpsn, fputs, fgets, putc, getc, strtoul, strcoll, ferror)
- New functions clrscr() and any_key_pressed() (see libndls)
- Touchpad support should now be fixed thanks to critor and Goplat, although I cannot test it on real hardware. The arrows and click are mapped to 1-9 as it has been suggested, as long as we cannot interact with the Touchpad hardware. Programs must be rebuilt to benefit from this update.
The particles demo should at least work, I'd like to read your feedback!

Yep! :)

I am rebuilding my stuff now and I will test on the touchpad promptly! :)


Everything seems to work fine!  Is this going to be the final solution for the touchpad for now (mapping the keys to the number keys), or is the actual arrow key support planned?  If this is the solution, I will get to updating the Block Dude passwords to reflect this change and I will upload the new version to ticalc.org promptly! :)

Tests done all keys except arrowkeys( no miracle :( ), on and the key to the right of "9" (0x1A, 0x100) named "Frac" on hackspire work as they should for me.

Great, thank you to both of you.

apcalc: I have personally not planned to work on the touchpad I/O ports, I suppose Goplat will document and implement this in nspire_emu as quickly as he used to. But I am not really happy with the current work around, I would prefer true support before the final release.

ExtendeD - I assume you tried the ftell call - what problems did you
  have by this uncomfirmed call ?(confirmed by me only). I did a simple
fseek(handle,0,SEEK_END);
size = ftell(handle);
printf("file size=%d\n",size);

EDIT: I think I just found memchr: noncas1.7 =>  0x102A60A0

Thanks, I'll try to include it.

Most of the syscalls are tested automatically with arm/tests/tests.c. These are not advanced tests but should be enough without taking to much time to write. ftell did pass the tests without any problem.

The following issue has been fixed:

  • Installation message replaced by a document format warning on real harware:
    The program loader is called before it is installed, earlier than on OS 1.7. The issue doesn't appear on nspire_emu.

The random crash when running program is really weird. I think I have already seen it during the alpha tests of Ndless v1.7, but it had disappeared. Now it's back.

I'm quite sure that:
- It is only reproducable on real hardware
- It depends on the program being run
- The crash always happens somewhere near ploaderhook.c's ((void (*)(int argc, char *argv[]))(docptr + sizeof(PRGMSIG)))(1, (char*[]){docpath, NULL});, i.e. the program execution
- Even a program containing only 'PRG\0'[bx lr] can crash
- This has nothing to do with argc/argv passed as parameters
- It happens with or without interrupts enabled
- The data run is never corrupted
- Lionel Debroux reports the issue with Ndless v1.7. I'm personally reproducing it with Ndless v2.0 on a Clickpad non-CAS OS 2.0.

Could there be some execution protection on the heap, but not for all the allocations?
