Trouble compiling PSGrooPIC

**CptAJ** · 11-09-2010,04:02 PM

I'm trying to compile the latest PSGrooPIC for my DIY board. Its a PIC4550 8mhz NoBTL for 3.41FW. I'm using the PCWHD 4.110 compiler and I keep getting around a hundred errors related to usb.h when trying to compile.

I tried using the command script provided in the source and it tries a bunch of times and fails at all of them. So I proceeded to trim the script to leave the error report and only try compiling the version I need. Here's the pertinent command:

Code:

ccsc +FH +Y9 -L -A -E -M -P -J -D +GFW341="true" +GLEDG=PIN_B4 +GLEDR=PIN_B4 +GDEFPL="true" main.c

and I get this error:

Code:

Error[27]   C:\J1M-PSGrooPIC-87c5f0b\usb.h 105 : Expression must evaluate to a constant
      1 Errors,  0 Warnings.

When compiling from the PCWHD IDE I get a more extensive error report which you can see here: RAW OUTPUT 1pcQfghY

I realize that I need to modify the source to support the 8mhz crystal but I'm trying to compile the untouched version first to make sure I'm not the one causing the problem by modifying the source.

At any rate, here's the modification I plan on doing for future reference (NOTE: I HAVEN'T done this part yet, what I'm talking about above is using the virgin source code from git):

Code:

#include <18F4550.h>
#fuses HSPLL,NOWDT,NOPROTECT,NODEBUG,NOBROWNOUT,USBDIV,PLL2,CPUDIV1,VREGEN,PUT,MCLR,NOLVP
#use delay(clock=8000000)

Could I get some help with the compiling process? I don't know what I'm doing wrong.
Also, if there's anything wrong with the modification I plan on doing after I figure out the first problem, feel free to point it out as well.

Thanks

CCS usb stack is patched ?

**jaekid** · 11-09-2010,05:24 PM

kindly post your usb.h file for analysis.

**CptAJ** · 11-09-2010,05:36 PM

usb.h
http://pastebin.com/bd7atCYn

usb_desc.h
http://pastebin.com/mwmuBk0p

I've made no changes and applied no patches. I just downloaded from github here:
https://github.com/J1M/PSGrooPIC

Code:

Build:
Fist, you need to convert the usb descriptor format to a big array as required by CCS compiler (doesn't support 
pointers to ROM), to do so just copy descriptor.h and psgroove.c to the source directory, and build GenDescriptors. 
To do so, you'll need a windows C compiler (VC++ or Mingw).

	with VC++: 
	cl gendescriptors.c

	or with mingw:
	gcc gendescriptors.c -o gendescriptors

If you get some error, you are missing some files.

Now, to build the descriptors, run
	gendescriptors > usb_desc.h

Now you need to modify the CCS usb stack. CCS stack distribution not allowed outside licensed users, so you'll need
to patch the one from your ccs installation:
copy usb.c,usb.h, pic18_usb.c and pic18_usb.h (they are in the Drivers folder in CCS) to your source directory and run:
	patch -p1 < stack.diff

Now you can compile the source to a .hex with

R.

So where do I find this gendescriptor.c file? I've seen several sites quoting this but not one mentions where to get the file.

I have the descriptor.h and psgroove.c file from the psgroove source. But from there it jumps to building gendescriptor.c which I don't know where to find

Wish this was a little more documented =(

i atach it here , and you can try iLLNESS source in his own thread with all patched files included already ...

**iLLNESS** · 11-11-2010,10:49 PM

my sources are here http://psx-scene.com/forums/546952-post5.html (iLLNESS's PSGrooPIC Hexes and Information Thread)

they may be harder to follow but they are current as of now so you dont need to mess with compiling pl3.

you should just need to comment out any bootloader related stuff in my source for it to work.

**CptAJ** · 12-12-2010,02:39 PM

Ok, I gave your source a try and it compiled fine. I made a few changes to support my DIY board.

Here are the fuses and clock lines.

Code:

#fuses HSPLL,NOWDT,NOPROTECT,NOLVP,NODEBUG,NOBROWNOUT,USBDIV,PLL2,CPUDIV1,VREGEN,PUT,NOMCLR
#use delay(clock=8000000)

I defined PSGROOPIC as the board...

Code:

#define PSGROOPIC

And commented out this whole section:

Code:

///////////////////////////////////////////////////////////////////////////
// NON BOOTLOADER USERS COMMENT ALL DATA FROM ABOVE ////// TO BELOW //////
// IF NOT USING BOOTLOADER PLEASE MAKE SURE TO SET #FUSES ACCORDINGLY TO MATCH YOUR BOARD!!!!!!!
// BOOTLOADER SCRIPT
/*
#ifdef BTL_USBHID
   #define BOOTLOADER USBHID
   #define CODE_START 0x1000
   #export (HEX, FILE=BOARD-VERSION_STRING-FIRMWARE-PLTYPE-PL3_COMMIT-BOOTLOADER.hex)
#elif defined (BTL_PICDEM)
   #define BOOTLOADER PICDEM
   #define CODE_START 0x0800
   #export (HEX, FILE=BOARD-VERSION_STRING-FIRMWARE-PLTYPE-PL3_COMMIT-BOOTLOADER)
#else
   #error Bootloader not defined
#endif
#build(reset=CODE_START, interrupt=CODE_START+0x08)
#org 0, CODE_START-1 {}
*/
///////////////////////////////////////////////////////////////////////////

And finally, I changed the led for my board on the psgroopic header file like so:

Code:

#define LEDR PIN_B4

Then I hit compile on PCWHD and everything went great. I loaded the hex onto my device and tried it... but it DIDN'T WORK.

The led flashes a bit then it stops and then it just stays flashing non-stop. The PS3 boots on with no positive results.

I've checked my device and everything seems fine but here's an EXACT drawing of it, did I make any mistakes?

Note: The led and resistor ARE in series to the ground line. I just didn't draw it in an obvious manner.

Any ideas? I'm stuck here
