 |
|
Does anyone know why sceIoOpen() with PSP_O_WRONLY flag doesnt work in flash0 ?
I tried
| Code: | | sceIoOpen("flash0:/test.txt",PSP_O_TRUNC | PSP_O_CREAT | PSP_O_WRONLY, 0777); |
But test.txt is only created if i open it in ms0:
| Code: | | sceIoOpen("ms0:/test.txt",PSP_O_TRUNC | PSP_O_CREAT | PSP_O_WRONLY, 0777); |
However, if i open test.txt to read only, it works:
| Code: | | sceIoOpen("flash0:/test.txt",PSP_O_TRUNC | PSP_O_CREAT | PSP_O_RDONLY, 0777); |
This way it works... Perhaps i have to use a differente mode, instead of 0777. (Tried with 0744, but doesnt work too) |

| flash0 needs to be unassigned and reassigned in write mode. By default only VSH mode (0x800) apps can do this. If your app is user mode then you can simply change it to 0x800. If your app is kernel mode (which I assume it is since you can read flash0), you'll need to increase your privileges. Look at the iop.prx source code. |
