Could there be some execution protection on the heap, but not for all the allocations?
Highly unlikely. nSpire is ARM9 and XN bit was only introduced in ARMv6. It looks more like some kind of timing issue.

Most probable cause is caches. Read this - does it look like what you are seeing?

Ah yes, caches could be a big issue. In the Ndless program loader, after loading a program try running this: (info taken from the arm926ej-s manual)
Code: [Select]
tc_loop: MRC p15, 0, r15, c7, c10, 3 @test and clean DCache
BNE tc_loop
mov r0,#0
MCR p15, 0, r0, c7, c7, 0 @invalidate ICache and DCache

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.
I am confused, does the strikethrough means you had it fixed, but then you discovered it was not and you added the [ s ] tag to your text so people disregard the post? ???

So how is this going?
Is the touch pad compatible yet?

All keys work, except arrow keys : but they are mapped to number keys (1 to 9).
And you have to rebuild all programs with the new version of ndless to use the touchpad keypad.

I still get the format warning message. (I did "make clean", before the rebuild (revision 351) )
So this isn't fixed yet...

Could someone please build the latest release for me? Or explain step-by-step how to do it? (I'm sorry for being a n00b.) I can't seem to figure out how to setup everything myself... :(

-install Msys + Mingw
-install 7zip
-install Yagarto
-add the 7-zip folder and the yagarto "bin-folder"  to your "Path" variable (on W7: Control Panel\System and Security\System # Advanced system settings # Environment Variables )
(to add: write ";" after the existing "paths" and copy paste)


open Msys
write: cd <path to ndless directory>/tools
write: make

add the crated "bin folder" (/something/ndless/bin) to your path variables

write: cd <path to ndless directory>
write: make

if I didn't miss something it should now build.
