tcl script problems about codewarrior

mgkiller — Tue, 13 Aug 2013 14:24:10 GMT

when i debug my p2020 and p4040 by using codewarrior, i have the following questions:

question 1:

there are 2 tcl scripts to initialize p2020, p2020_core_init_cacheon.tcl and p2020_core_init_ram.tcl, i can do step debugging with p2020_core_init_ram.tcl in DDR, but i can't do that with p2020_core_init_cacheon.tcl in SRAM, my question is whether i cando step debugging in SRAM with p2020_core_init_cacheon.tcl?

question 2:

when i do step debugging my p4040 with p4040_core_init_ram.tcl in DDR,i found the cpu always infinite loop in below code：

########################################################

# IVOR6 - 0x0700 Program

########################################################

.org 0x700

nop /*cpu infinite loop here*/

isr_prologue

li r3,0x0700

lis r4,InterruptHandler@h

ori r4,r4,InterruptHandler@l

mtlr r4

blrl

isr_epilogue

########################################################

why?

question 3:

when i program norflash on my p4040 using p4040_core_init_ram.tcl, i got the error below:

Performing target initialization ...

Downloading Flash Device Driver ...

Error: Couldn't write flash driver to target. Memory verify failed at location: 0x0000201c.Please make sure you are not trying to write to a read-only location.

but as you see, i can succeed to access the whole 512MB DDR space, why codewarrior say memory verify failed?

thanks for your concern,any help is appreciated!

Hi,

For the first question, those .tcl file are your custom initialization file right? I think you need to share the two files and describe what errors you meet?

Hi,

For the second question, from the code you provided, the core has entered a program interrupt.

It occurs under several conditions: floating-point enabled, illegal instruction, privileged instruction, trap and unimplemented operation.

Please check Guest) Exception Syndrome Register (ESR/GESR) for which happened.

Hi,

For the third question, please check the address "0x0000201c" in your memory map, check in .tcl file in which area is this address.
