Error 800200D9 when try to start a user app converted...

[darkness]

Hi,
I've try to port my hb in kernel mode, and using PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_USER);
set the main thread to user mode...
But when I launch the hb I've error 800200D9!
(failed to allocate memory block)
Why?
I think makefile is useful:

Code: Select all

TARGET = explorer
OBJS = main.o osk.o framebuffer.o graphics.o general.o

BUILD_PRX = 1
PSP_FW_VERISION = 380

CFLAGS = -O2 -G0 -Wall -g
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBS =  -lpspgum -lpspgu -lpng -lz -lm -lpspumd -lpspusb -lpspusbstor -lpsppower -lpsprtc -lpspusbdevice -lpspsystemctrl_user
LDFLAGS =

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = dfsdaadfsdfadfafdasfd

include $(PSPSDK)/lib/build.mak

you do not have your psp 1.50 kernel enabled or you are putting your homebrew in the wrong folder (if you have 1.50 kernel plugin installed)

[J.F.]

When you have BUILD_PRX = 1 in the makefile, you need to specify the heap size or you're stuck with 64K.

I use

Code: Select all

PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER);
PSP_HEAP_SIZE_KB(-1024);

Note that the negative heap size tells how much memory to leave to the PSP, not how much to allocate to the app, and requires a very new toolchain, so if you haven't updated in a while, do so.

is there any reason why that this cant be a preset in the SDK but then we can override it if we need to?

[J.F.]

The current code in newlib specifically sets PRXs to 64KB unless some value is set. I think that was for people doing plugins and libs, but now with 3.xx user-mode, apps are now PRXs too, so maybe the default needs to change.

No it doesn't because something like that would be a serious breaking change.

No it doesn't because something like that would be a serious breaking change.

True, plus since the author clearly has to make changes to make an app run as 3.xx user prx, it SHOULD be no trouble for them to add a heapsize to the app at the same time. So I guess leaving it as is would be the best thing.
