sceKernelExitVSHVSH(NULL); - Does nothing. I've got black screen, but I think psp is not hanged, because it doesn't power off.
Any solution? (note: I know about sceKernelExitGame(); but I want to use this to restart vsh)

You need to give the VSH parameters structure with arguments to restart from Sony logo.

But even in 1.50 POC sceKernelExitVSHVSH has NULL instead of SceKernelLoadExecVSHParam structure.
Edit: And even in 1.50 POC recovery it's not working :) (when testing on high firmware)

But what arguments? In sources I have, this structure is used to boot an EBOOT.

The vshargs for Sony logo is just 0 I think. The args give information to the VSH such as error messages to display and position of music player etc.

IIRC sceKernelExitVSHVSH is kernel mode only.

Do you have information about the syntax of vshargs?

I don't believe any args are required to be passed. I use sceKernelExitVSHVSH to reboot the 5.03 HEN and I just pass NULL.

So...Recovery can't be in kernel mode, but this function needs kernel mode...

I've included pspvshbridge and replace this by vshKernelExitVSHVSH.

Still not working! ;/

I have two questions:
What is the "flach0"? I've found this in DCv6 source. Moonlight has made a new driver for flash0 or something? But why?

I want to patch the Sony Updater like 5.00m33 updater. Something like this

Code: Select all

SceUID sceIoOpenPatched&#40;const char *file, int flags, SceMode mode&#41;
&#123;
	u32 k1 = pspSdkSetK1&#40;0&#41;;	

	if &#40;strstr&#40;file, "display_02g.prx"&#41;&#41; //Updater is creating a file in flash0, lets flash CFW files! &#40;It's a Slim PSP!&#41;
	&#123;
          flashCfwFilesSlim&#40;&#41;;
	&#125; else if &#40;strstr&#40;file, "display_01g.prx"&#41;&#41; //Updater is creating a file in flash0, lets flash CFW files! &#40;It's a Fat PSP!&#41;
	&#123;
          flashCfwFilesFat&#40;&#41;;
	&#125;

	pspSdkSetK1&#40;k1&#41;;

	return sceIoOpen&#40;file, flags, mode&#41;;
&#125;

will be enough or it's more complicated to do? And I must patch the IPL writting of course.

Look into SystemControl Lib for your first question !!!

I mean the information passed back to VSH when you exit after launching an EBOOT. When you replace vshmain and launch the real one later if you don't pass the vshargs then it forgets the positions in the XMB such as last played song, video etc, and the seconds played in the song ( it resumes in the middle of the last song even after exiting a game). Ex. The arguments to exit to VSH and skip the Sony logo are given in the 1.50 POC.

My recovery can now acces flash0! :)
Exitting still not working - I must experiment more with this.

Edit:
GENs are packing recovery (it's a vsh module!), m33 are packing recovery, but PSP-Packer can't... :( Not so funny...
Edit2:
I've figured it out by myself. I can pack them, too.

Edit3:
after some tests, sctrlKernelExitVSH worked for me.
