Why are you in the flash? Can you get to the recovery menu? Try to add to the makefile "LIB = -lpspi2c_driver"?[/url] He has the library loaded compiler-side, just not prx-side, similar as if you were to try to make a usb connection with none of the usb modules loaded. I'd borrow loadstar...

!_!
I just bricked my PSP......

I "cut" the clockgen.prx from flash0 to my computer......

Holly shit!

What prx or library are you loading it from. It's in the libpspi2c_driver.a that already in my pspsdk. Is that means after compile and link, my prx also need to load another prx that contain this function? Or the function is already linked from libpspi2c_driver.a to my prx? I found this function in...

Sys:5.00M33 I want to send datas to the I2C bus, so I made an I2Csend.prx and loaded it in my programme to use my functions in kernel mode.The function: int I2Csend(u8 a,u8 b) { u8 param1[4]; param1[0]=a; param1[1]=b; int k1 = pspSdkSetK1(0); int res=sceI2cMasterTransmit(0x42, param1, 2); pspSdkSetK...

I'm now using a simple method below, but I think it is not fast enough, hope some faster methods or sceGU hardware functions. Codes: for(m=0;m<16;m++) { vp=&pic_buffer[ii][begin_m+m][begin_n]; mm=m>>1; mn=(m>>3)*2; for(n=0;n<16;n++) { Y=iclpp[dct_recon[mn+(n>>3)][m&7][n&7]]; nn=n>>1; *(v...

The usb just export digital data, remotejoy is output the framebuffer, not an analog signal. I think the audio DAC mustn't have the ability to output both video and audio. The audio DAC can only transfer and output 48KHz analog signal about 0~+3V, but the video signal need above 10MHz and a higher v...

I used the ME to IDCT a 8X8 short block, but it doesn't work correctly. Codes: static int idct_me(int start_block) { idct_start((short*)(int(&dct_recon[start_block][0][0])|0x40000000)); return 0; } static void idct(int start_block) { int err; err=BeginME(mei, (int)idct_me, start_block, 0, 0, 0, ...

I just thought that you had already defined the functions of these flags, now I realize those are for me or someone who use the struct to define our own meanings. Yes, and you can also extend the structure if you want, putting your own stuff in it. @realjoeeye1 - They are the same address, but you ...

nope it means we want to read/write into uncached segment as both processors cannot share the contents of their respective caches. The "|0x40000000" operation gives the same result in both processors : bypass the cache update, don't read/write in the cache even if there may be a hit but d...

I'm not sure what the sigmask and sigset exactly mean, can J.F. give a simple explanation? It's an idea from the Amiga. Each bit is a signal. You can alter any number of bits by setting the bit number of the flag to be altered in sigmask. The value for the flag is determined by setting the same bit...

Yes, I'm sure I've put the mediaengine.prx to the same folder with the EBOOT.PBP. It didn't work on the old EBOOT.PBP, and work fine on the new EBOOT.PBP that I compiled.

Thanks!

I'm not sure what the sigmask and sigset exactly mean, can J.F. give a simple explanation?

I've tried J.F.'s sample code, the EBOOT.pbp already compiled did not work, it received an 80020001 error code loading the .prx. But when I recompiled it, it works well! Maybe I have to rewrite my codes based on J.F.'s MediaEngine.prx.

I've not used ME to access the VRAM. When load my prx, it received an error code:800200d9, like there was not enough memory to allocate. I used PSP_HEAP_SIZE_KB(10*1024) both in prx and eboot.pbp, it doesn't work.

Is the "|0x40000000" opration means the ME has another address to access the memory? Are the "|0x40000000" address on ME and the original address on SC pointing to a same place?

Many thanks!!

I saw your posts,J.F. but the download link of your sample code may be broken or I'm banned to download it.
I read many posts, and made a prx to use the kernel mode. But the functions in the prx don't work. No error code received but the functions just not work like they are not be called.

Problem solved!!
Thanks for replying!

I use fp=sceIoDopen to get an fp, and use sceIoDread(fp,dir) to recieve the dir entry. But it always return a negative means an error.
what is wrong?

My psp is slim, 4.01M33

Sys:401M33
I tried to use the ME, but got the 8002013C error code. I checked the .prx file, which used functions in sysreg.prx, but there is no such a file in my flash0, and maybe it need the kernel mode.

How can I use the ME on PSP with 4.01M33? Please help.

THX.
