HARD FAULT uVisor

xfolder · June 8, 2016, 9:21am

Hi,
I’m trying to test uvisor on my board. When I launch my application in the debug mode, I have this error :
“\r\tbox[0] acl[00]={0x20000000,size=10368,acl=0x00000030,HALT_ERROR(core/system/src/mpu/vm
pu_armv7m.c#462): box size (10368) not "
327,093 @“ounded, rounding disabled (rounded=16384)\n”
327,126 @”\r\n"

I think it’s due to SRAM and HOST SRAM configuration which is the following :

#define SRAM_LENGTH_MIN  0x40000  
#define HOST_SRAM_ORIGIN_MIN 0x20000000
#define HOST_SRAM_LENGTH_MAX 0x40000
#define SRAM_ORIGIN  0x20000000
#define SRAM_OFFSET  0x0

Anyone could help me?

I made some changes in my configuration and now i have this error :

The problem was due to SRAM, i didn’t configure the SRAM and HOST SRAM correctly, now, I’ve got a BUS FAULT :
I though the problem was the region of 0xE000E000, but i made sure to declare it in my ACL

The problem was resolved and it was due NVIC vectors functions, when we use uvisor we should use vIRQ_functions instead
