Now how can i boot this .elf with SDcard ?
How can i convert my .elf to .cdi ?

You have to convert elf to bin first then create iso for loading from sd card .

Thanks for your answer but my questions are :
- how convert .elf to .bin ?
- how launch .bin with my SDcard ? (with DreamShell ?)

Thanks.

For an unscrambled binary (which you cannot burn to a cd without scrambling first), do this (assuming your toolchain is sane):

Code: Select all

sh-elf-objcopy -R .stack -O binary file.elf file.bin

You can scramble the binary (only for making a bootable CD) using Marcus' scrambling tool, for which the source code can be found at http://mc.pp.se/dc/files/scramble.c .

Or this http://dchelp.net/Apps/elf2bin_console_dll_10.zip ?

If you're compiling code yourself, there's little to no reason to be using elf2bin. Especially since its probably just a renamed version of sh-elf-objcopy anyway.

Oh

yes. Thanks again.

DreamShell can't load the .bin.
How can i load the .bin without codercable ?

I've never used DreamShell, so I have no idea.

I have made a script to build a .cdi image from a compiled elf! Assuming you use windows, this should work for you.

Just name the elf 1st_read.elf and place it in the /data folder then run CDi4DC.bat
( you can also set the elf name to something else, just look at CDi4DC.bat )

Hope that helps!

Thanks PH3NOM but your MU link is break. :/

Link fixed, sorry it was a typo:-)

4 ways to test code on DC:
1-CD-Rom
2-Coders Cable
3-BBA
4-SD card

2-4 still require a boot disc of some sort

I only use method 1, and I have given you all the help I can with that.
Maybe some others here feel like sharing how to use methods 2-4, but there should be more than enough info available searching the net...
