I have found an other location to update in Ndless 1.7 source code for CAS OS.
Here it is :
./arm/loader.c line 51
Code:
static unsigned const ld_currentdocdir_addr[] = {0x10669A9C, 0x1069BD64};
By the way, here is my actual IDC file.
It is not a complete conversion, it may misses all the WIFI support (adresses > 0x1077C0000)
[attachment=3286:OS_cas-1.7.idc.txt]
edit : Found another adress that I have forgotten.
./arm/loader.c line 30
Code:
static unsigned const ld_hook_alloc_patch_addrs[][3] = {
{0x107957B0, 0x100002C0, 0x10000088}, // 1.7 non-CAS
{0x107597A0, 0x100002C0, 0x10000088} // 1.7 CAS
};

Sorry for double posting but I have fixed some fails in adresses : some identical adresses were defined many and many times whereas it was not the same routine.

Hey, I was wondering if I get an Nspire...
How good is NDLESS for programming it, or is it very incomplete? |

Ndless 1.1 is fully stable on OS 1.1 and we can do anything we want. Really.
On a other hand, Ndless 1.7 that works with OS 1.7 is on beta state and is instable for the moment. |

hmm...
sounds cool, but I'll wait a bit longer before making rash decisions. Maybe once ndless 1.7 is stable, I might huy a normal nspire with a 84+ keypad or something. |

| Though, you should be aware that if you wait, TI might release an OS that blocks downgrades to OS 1.7 |

Simple binary searches aren't fool proof and here is an example of one: fread and fwrite.
Edit OS_cas-1.7.idc.txt for these corrections:
Code:
MakeName (0X102A6EC0, "fread"); => MakeName (0X102A6EC0, "fread"); // nochange
MakeName (0X102A6EC0, "fwrite"); => MakeName (0X102a7274, "fwrite");
Notice fread and fwrite have the same address, origially.
This is important if your are updating syscalls_cas-1.7.c
A "smarter" binary search skips the bl ?????? instruction to the next one for a unique match. |

I found out my friend is selling his Nspire for $50, and I might buy it. Good thing is, it's a really old one too! |

Thank you for your notice. I know that the script I used to migrate is not perfect.

Put this in syscalls-light_cas-1.7.c
Code:
0x102A6CCC
, 0x102A6EC0
, 0x102A481C
, 0x102A475C
, 0x102AC2DC
, 0x102A74D4
and in syscalls_cas-1.7.c
Code:
0X102A6CCC
, 0X102A6EC0
, 0X102a7274
, 0X102A66C4
, 0x102A6A24
, 0x102A31D8
, 0x102A31CC
, 0x102A82E4
, 0x102A812C
, 0x102A80EC
, 0x102A475C
, 0x102A481C
, 0x102A46D0
, 0x101740B4
, 0x10213C18

, 0x102AD870
, 0x102AD8E8
, 0x102A83BC
, 0x102A83FC
, 0x102A8474
, 0x102A844C
, 0x1001D434
, 0x102A85B4
Compile and run on the emulator with a CAS flash.
UPDATE: I compiled it myself and the NONCAS installs on the emulator, while the CAS
almost installs - I get a "Ndless installed!" , but does not take.
UPDATE: change in /arm/install.c line 30 from:
Code:
static unsigned const ins_ploader_hook_addrs[] = {0x1000921C, 0x1000091E8};
to:
Code:
static unsigned const ins_ploader_hook_addrs[] = {0x1000921C, 0x100091f0};
Now runs on both CAS-NONCAS flashes. Not tested on calculators, . I will probably post the binaries as "betas" -
The installer will look for ndless_res__beta.tns instead of ndless_resources.tns so it wont be confused later with
a stable release.

Thanks for sharing but I still can't install Ndless 1.7 on a CAS flash.
I always have the message "This document format is not supported" after the supposed installation, when I want to launch a C prog that works with Ndless 1.7 on nonCAS flash.
I checked all your adresses, that let me see that there were an other mistake in IDC (I have also seen a big couple). Whitch revision of Ndless do you use (I use rev 256)? Where do you get the message "Ndless Installed" ?

It should be in nspire_emu's console (RS232 output). |

w00t, the Goplat 0.26 gtk Nspire emulator doesn't display that (I know that we are at v0.31 but I liked the shinny gtk mod that xspire made for the v0.26 ).
I'll try with the new version with the patch.

I get it works on an hardware CAS !!
Thank bsl, I missed the over last 0 :D
So, here all the modifications to do :
./arm/utils.c line 52
Code:
// addresses of OS global variables which must be reinitialized for proper OS reboot
static unsigned const ut_os_reboot_reset_addrs[][3] = {
{0x106DAFC4, 0x106F2A0C, 0x106F2AF0}, // 1.7 non-CAS
{0x1070D28C, 0x10725314, 0x107253F8} // 1.7 CAS
};
/arm/install.c line 30
Code:
static unsigned const ins_ploader_hook_addrs[] = {0x1000921C, 0x100091F0};
./arm/loader.c line 30
Code:
static unsigned const ld_hook_alloc_patch_addrs[][3] = {
{0x107957B0, 0x100002C0, 0x10000088}, // 1.7 non-CAS
{0x107597A0, 0x100002C0, 0x10000088} // 1.7 CAS
};
./arm/loader.c line 51
Code:
static unsigned const ld_currentdocdir_addr[] = {0x10669A9C, 0x1069BD64};
My actual IDC (all lines suffixed by a // have to be reviewed because there are wrong)
[attachment=3290:OS_cas-1.7.idc.txt]
By the way, Ndless 1.7 can be installed without the previous random (I think it is an ExtendeD modification) on an Hardware Nspire (without the tip to do, permanent link also works)
I thnik on the way of the installation, Ndless 1.7 is stable. On the other hand, the bug of the teta is still there.
\o/
(I am so happy you can't imagine how much  )

You did great Levak!
I'm not sure you even took the time to sleep for the last 5 days!  |

Hello_beta.tns might be better for the emulator.
See if Goplat's NES emulator works. |

Oh yes it works perfectly (some ROMs doesn't want to run like Tetris or FF3) but in general it is awesome (like Ndless 1.1) |
