Hi.

startware,startup.c,line87:

 
static unsigned int const vecTbl[14]=
{
    0xE59FF018,    /* Opcode for loading PC with the contents of [PC + 0x18] */
    0xE59FF018,    /* Opcode for loading PC with the contents of [PC + 0x18] */
    0xE59FF018,    /* Opcode for loading PC with the contents of [PC + 0x18] */
    0xE59FF018,    /* Opcode for loading PC with the contents of [PC + 0x18] */

    0xE59FF010,    /* Opcode for loading PC with the contents of [PC + 0x10] */
    (unsigned int)Entry,
    (unsigned int)UndefInstHandler,
    (unsigned int)SVCHandler,
    (unsigned int)AbortHandler,
    (unsigned int)IRQHandler,
    (unsigned int)FIQHandler
};
 
 
AM335xTRM_G,Table 26-3. RAM Exception Vectors :
 
 
Address             Exception                     Content
4030CE00h         Reserved                     Reserved
4030CE04h         Undefined                     PC = [4030CE24h]
4030CE08h         SWI                             PC = [4030CE28h]
4030CE0Ch         Pre-fetch abort             PC = [4030CE2Ch]
4030CE10h         Data abort                     PC = [4030CE30h]

4030CE20h         Reserved                     20090h
4030CE24h         Undefined                     20080h
4030CE28h         SWI                             20084h
4030CE2Ch         Pre-fetch abort            Address of default pre-fetch abort handler (1)
4030CE30h         Data abort                 Address of default data abort handler (1)
4030CE34h         Unused                         20090h
4030CE38h         IRQ                         Address of default IRQ handler
4030CE3Ch         FIQ                         20098h
 
Yes, startware relocates the base 4030CE00 to 4030FC00,But,what I don't understand why the sequence of vector table is different bewteen startware and the TRM?
 
 
 
Thanks
