chishm's bootloader in new libnds, tutorial?

[Tomdev]

hello everyone

every time i trie to get this loader working the compiler says likely type-uning may break strict aliasing rules:

d:/devkitPro/combined/arm9/source/nds_loader_arm9.c:72: warning: likely type-pun
ning may break strict-aliasing rules: object '*src16' of main type 'short unsign
ed int' is referenced at or around d:/devkitPro/combined/arm9/source/nds_loader_
arm9.c:72 and may be aliased to object '_io_dldi' of main type 'unsigned int' wh
ich is referenced at or around d:/devkitPro/combined/arm9/source/nds_loader_arm9

has someone got it to work, and if so, could you please say how?

[dovoto]

Been trying to get it to work as well. Having issues mainly because fatlib has changed since he has posted the loader. I will post if i get it figured out.

[Tomdev]

what's actually new in libfat, and who made the update? maybe he knows the problem. and if you solve it, i'm so happy if you could post the solution

[Tomdev]

ok, after i removed that error about type punning i saw the source of boot.bin and I think it isn't compatible with the newest libnds. maybe we have to change it to let it work?

[feraligatr]

"disk io dldi" goes from libfat to libnds 1.3.1
so you should use "io_dldi_data" instead of "&_io_dldi"

you said load.bin is incompatible with newest libnds. could you give more details?

[Tomdev]

i already tried what you said, and the .bin file is incompatible i think because there are irq inits which break your codes, or doesn't this affect you program because it's still not working(although i don't get error's anymore)

[dovoto]

Chishm lent us an updated loader. I will ask him if he has a public link to it.

[Tomdev]

that would be great , i had also spoken Chism in a post on gbadev where he said something about an updated loader

[xiao32]

yea, it doesn't work for me either. Which sucks, because I really need it.

Anyone know of another bootloader? (Please dont suggest HomebrewMenu, it doesn't work either (probably cuz its simply an old/modded version of chishms))

[WinterMute]

HomebrewMenu works fine, we use it regularly.
