HI, ARM,
I ran into an issue that seems to reveal that Fast Model application loader has a bug in handling UNINIT execution regions. If I added this load region to my scatter loading script file:
LR_DRAM0 0x1000000000{ ER_DRAM_RAMDISK +0 ALIGN 4096 EMPTY UNINIT 0x10000000 ; 256M
{ }}
Then when I run my simulation model with -a option to specify my executable (.axf), it takes remarkably long time to load the application. So I guess the loader has been zeroing that large UINIT area, though it has been specified as UNINIT.
I didn't see such an issue with ARM development studio (i.e., loading the application via ARM DS debugger).
Thanks

Hi Oscar,
Which do you use, free of charge (FoC) FVP or else e.g. Fast Models?
If you license commercial products such as FM, ArmDS, you can create a support case through https://support.developer.arm.com/my-cases/ and provide more details about the symptom e.g. FM version, ELF file, the steps to reproduce etc.
Kind regards,
Toshi
