Tool/software: Code Composer Studio
Hello, I use SafeTi library with version 2.4.0. And I have some question about relation between linker.cmd and HL_sys_mpu.asm.
1. In SafeTI Diagnostic Library, The used linker cmd file is "SL_TMS570LC4357_NoOS_sys_link.cmd" in path \build\TMS570LC4357_NoOS.
And mpu asm file is HL_sys_mpu.asm in path \demo_app\HALCoGen\TMS570LC4357_NoOS\source
Is it right?
2. if the question 1. is right, I think the mpu setting is different between two files. It is no matter to act?
example : in the HL_sys_mpu.asm
the register set follows.
r1Base .word 0x00000000
r2Base .word 0x00000000
r3Base .word 0x08000000
r4Base .word 0x08400000
r5Base .word 0x60000000
r6Base .word 0x80000000
r7Base .word 0xF0000000
r8Base .word 0xFC000000
r9Base .word 0xFE000000
r10Base .word 0xFF000000
r11Base .word 0x08001000
r12Base .word 0x20000000
r13Base .word 0xF0000000
r14Base .word 0xF8000000
r15Base .word 0xF8000000
r16Base .word 0xF0000000
But in the linker cmd file, the register is set more details
/* Memory Map */
MEMORY

FEE (R) : origin=0xF0200000 length=0x00000064 fill=0xDEADBEEF /* For FEE testing, Valid only for sample application */
}
3. Can i know about the HL_sys_mpu.asm file is acted in details?
I anaylze the mpu file as follows. ( Please, add the comments the line where i don't know)
; Setup region
mov r0, #2
mcr p15, #0, r0, c6, c2, #0
ldr r0, r3Base // this is start addr
mcr p15, #0, r0, c6, c1, #0
mov r0, #0x0008 // mpu region type
orr r0, r0, #0x0300 // mpu region access permition
mcr p15, #0, r0, c6, c1, #4
movw r0, #((0 << 15) + (0 << 14) + (0 << 13) + (0 << 12) + (0 << 11) + (0 << 10) + (0 << 9) + (0 << 8) + (0x11 << 1) + (1))
mcr p15, #0, r0, c6, c1, #2
