IOP module loading from EE memory is not supported in the BIOS modules by default, you need to use the sbv patches library in PS2SDK which enables it by patching the running modules.
You can check my mplus loader source as a reference on how to use sbv:

hi thanks for the reply
the same thing still happens.
here is wat my files look like nw:
main.c
| Code: |
#include <tamtypes.h>
#include <debug.h>
#include <fileio.h>
#include <iopcontrol.h>
#include <kernel.h>
#include <loadfile.h>
#include <sbv_patches.h>
extern u32 ps2ips_irx;
extern u32 size_ps2ips_irx;
int main()
{
int ret;
init_scr();
SifLoadFileInit();
SifExecModuleBuffer(&ps2ips_irx, &size_ps2ips_irx, 0, NULL, &ret);
scr_printf("Module Loaded");
SleepThread();
} |
Makefile:
| Code: |
EE_BIN = test.elf
EE_OBJS = test.o ps2ips.o
EE_LDFLAGS = -s -Ttext 0x01800000 # Load ELF at 24 MB offset
EE_LIBS += -lps2ip -lc -ldebug -lpatches
EE_CFLAGS = -DRESETIOP #-DDEBUG
all: $(EE_BIN)
clean:
rm -f $(EE_BIN) ORG_$(EE_BIN) $(EE_OBJS) ps2ips.s
ps2ips.s:
bin2s ps2ips.irx ps2ips.s ps2ips_irx
$(EE_BIN) : $(EE_OBJS)
$(EE_CC) -mno-crt0 -T$(PS2SDK)/ee/startup/linkfile $(EE_LDFLAGS) \
-o ORG_$(EE_BIN) $(EE_OBJS) $(EE_LIBS)
ps2-packer-lite ORG_$(EE_BIN) $(EE_BIN)
include $(PS2SDK)/samples/Makefile.pref
include $(PS2SDK)/samples/Makefile.eeglobal |

You havn't called the patch function sbv_patch_enable_lmb
Check the header sbv header:
sbv_patches.h

greetings lukasz,
we still have no luck.
Thanks agan
| Code: | int main()
{
init_scr();
scr_printf(" Loading Modules...\n");
int ret;
SifLoadFileInit();
sbv_patch_enable_lmb();
SifExecModuleBuffer(&ps2ips_irx, &size_ps2ips_irx, 0, NULL, &ret);
scr_printf(" Loaded Modules...\n");
}

Further greetings,
It turns out the IRX has been loaded successfully (I know because I added a scr_printf afterwards), but when calling ps2ip_init() it just hangs.
I am not using Ps2link to test this.
Thankz |

You need to load some modules before ps2ip.irx. SifExecModuleBuffer in your case probably returns -203, which is a dependency error.
As suggested in this thread, take a look at existing source code and go from there.
You need to research more on your own, look at existing source code etc. Instead of asking very basic questions you can easily find the answer for yourself, because eventually people will just stop caring and answering them :-)
