Does not work with nusys demos.

[trhodeos]

For whatever reason, nothing boots. Need to investigate a bit more.

[deadcast2]

Huh, I tried compiling and running the nu0 demo and it performed fine. Maybe you fixed this issue already? :)

[trhodeos]

Yeah, I think this issue is a bit old.. However, last I remember, I couldn't get all of the nusys demos working, only the first couple.

Hello:
I'm new to N64 development (and low level programming for that matter).
I've been trying to compile the samples from nusys with no success. Everything seems to be going OK (codesegment.o file is generated), until spicy is run.

These are my files

• Shell script
• Modified Makefile for nu0
• Modified PRdefs

I'm using Windows 10. spicy is inside N64_TOOLCHAIN folder with all n64chain exes.

Hello!

What's your spec file look like?

[AlejandroGuardado]

Hello!

What's your spec file look like?

Mostly the same as they are on the sample folders. I only changed the "codesegment" line:

#include <nusys.h>

/* Use all graphic microcodes */
beginseg
	name	"code"
	flags	BOOT OBJECT
	entry 	nuBoot
	address NU_SPEC_BOOT_ADDR
        stack   NU_SPEC_BOOT_STACK
	include "$(CURRENTDIR)/codesegment.o"
	include "$(ROOT)/usr/lib/PR/rspboot.o"

endseg

beginwave

endwave

[deadcast2]

Thanks, the spec looks fine to me. Could you try running spicy with the "-d" verbose option? Might give us some more clarification to where the problem is occurring.

Can you provide your spec and nu5.out files? I'd like to try myself using the prebuilt toolchain I'm using in UltraEd. Thanks

I took a look here:

spicy/spec.go

Line 205 in 47409fb

if seg.Flags.Object {

but nothing jumped out at me. I'm not an expert go developer however...

EDIT:

Upon further inspection, the lone hyphen in the command ''mips-n64-gcc -P -E -U_LANGUAGE_C -D_LANGUAGE_MAKEROM - -I/usr/include/n64/nusys" just before the -I seems suspicious... that hyphen like that is for stdin i believe...

EDIT EDIT:

If I comment out the wave section in the spec, I get the following:

`spicy -d --as_command=mips-n64-as --cpp_command=mips-n64-gcc --ld_command=mips-n64-ld --objcopy_command=mips-n64-objcopy -I/usr/include/n64/nusys -s 32 -r 3rdPersonDemo.n64 -e 3rdPersonDemo.out spec

The parsed output appears to be empty...

When I run the built rom, it physically executed without crashing, but nothing happens. I suspect the jump to 0x400 (ish) happens, but there are no more instructions to execute, because the rom is not assembled correctly...

But I am not sure...

[nterry]

Ok, instead of editing my comment again, I think Ive found one of the issues...

Turns out, you dont check for null here:

spicy/spec.go

Line 205 in 47409fb

if seg.Flags.Object {

So if the 'included' segment by the given name on the current statement on the current wave doesnt exist, the code proceeds and throws an exception

For example, heres my spec:

#include "include/main.h"
#include <nusys.h>

beginseg
name "code"
flags BOOT OBJECT
entry nuBoot
address NU_SPEC_BOOT_ADDR
stack NU_SPEC_BOOT_STACK
include "codesegment.o"
include "/usr/lib/n64/PR/rspboot.o"
include "/usr/lib/n64/PR/gspF3DEX2.fifo.o"
include "/usr/lib/n64/PR/gspL3DEX2.fifo.o"
include "/usr/lib/n64/PR/gspF3DEX2.Rej.fifo.o"
include "/usr/lib/n64/PR/aspMain.o"
include "/usr/lib/n64/PR/n_aspMain.o"
include "/usr/lib/n64/PR/gspF3DEX2.NoN.fifo.o"
include "/usr/lib/n64/PR/gspF3DLX2.Rej.fifo.o"
include "/usr/lib/n64/PR/gspS2DEX2.fifo.o"
endseg

beginseg
name "pbank"
flags RAW
include "src/audio/bank_sfx.ptr"
endseg

beginseg
name "wbank"
flags RAW
include "src/audio/bank_sfx.wbk"
endseg

beginseg
name "sfx"
flags RAW
include "src/audio/bank_sfx.bfx"
endseg

beginwave
name "3rdpersondemo"
include "code"

include "bank_sfx_pbank"
include "bank_sfx_wbank"
include "bank_sfx_sfx"
endwave

/*
beginseg
name "gfx_dl_buf"
after "code"
flags OBJECT
include "src/gfx_dl_buf.o"
endseg

beginwave
name "nulod"
include "code"
include "gfx_dl_buf"
endwave
*/

In the wave, the 'bank_sfx_pbank' segment doesnt exist (the 'pbank' one does). So if i change it to 'pbank' (and all the other ones as well), i get a successful build.

However, the ROM still hangs...
