 |
|
I've this function to load the flash0 in rw mode:
| Code: |
sceIoAssign("flash0", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);
|
But on the Slims is opened in read only mode, is possible to load this in write mode?

Look in DAX's CF the proof of concept source code.
He's writing to flash there.

That was back on 1.50, he's asking about the slim,
but it must be possible. It has custom firmware on it somehow.

Writing in the flash is same for 3.XX.
Just ensure you have 0x800 as module flags, and PSP_THREAD_ATTR_VSH for the main thread. And don't forget to unassign the flash before assigning it in write mode. |

It is possbile,put the src in this Kernel Mode:
| Code: | PSP_MODULE_INFO("APP", 0x800, 1, 0);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_VSH); |
I have it in my application Multi PSP and it works successfully ;) |

| Use BUILD_PRX = 1 in the makefile. An elf with that param will give error. |

Here the makefile to work:
| Code: | TARGET = main
OBJS = main.o
INCDIR = ../include
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS) -c
LIBDIR = ../lib
LDFLAGS =
LIBS = -lpsppower
LDFLAGS = -lm
PSP_FW_VERSION = 371
BUILD_PRX = 1
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Access Flash Slim Sample
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak
