I did find PSP-IPL-SDK Rev.0.5 (2007.10.9) post from a forum. Anyway the source is here at https://github.com/soywiz/psp_ipl_sdk

Here what the person said from a forum. No I'm not posting the link here. Look up the name of UncertainGod. The reason is that I do not want to post a link that have a ton of ROM's hidden or what ever. I never did check the forums out to see. Don't care. Not even sure this is useful for us and MAME Dev team. I'm not gonna try until someone else tested this out first. This tool just might ruin the PSP.

Code:


PSP IPL SDK released
Booster recently informed the maxconsole website that he is releasing the PSP IPL(Initial Program Loader) SDK(Software Developers Kit) to the community.

Nothing much more to be said really other than the possibilities this could open up, for example having a complete custom firmware without one bit of sony code in it, or port the linux kernel and build the ultimate multimedia/emulator OS for your PSP hardware.

I can see some interesting projects coming out of this, what do you think?


A copy of the readme and the download link are below.

Note: Link no longer have the download anymore.

kprintf message

Connect a serial port via HPRemote with 115Kbps.
The output of Kprintf() out there.
Plug mini-jack because SYSCON cuts power automatically when pulling out a plug.

MultiLoader file format

see MS_MULTI_LOADER/readme.txt

Top address of MultiLoader bootcode

"PROVIDE (__executable_start = 0x040e0000); . = 0x040e0000;"
in "IPL_SDK/pspipl.x"

----------------------------------------
DDR-SDRAM

The DDR-SDRAM can not use because it isn't initialized.
The simple way of using SDRAM is to be in the hook after main.bin is initialized.
see the "ML_DDRDUMP" example.

finally,the original SDRAM driver should be made.
