Loading and Debugging into SRAM works, FLASH does not

Hi there,

i have following toolchain on ubuntu 8.04 LTS:

  1. binutils 2.17

2-4) gcc 4.1.1

  1. newlib 1.14

  2. gdb 6.8

  3. eclipse cdt - 3.4.0 (genymade)

  4. zylin embedded cdt plugin

  5. openocd SVN977

JTAG: openOCD-USB from embedded-projects.net

Eval-Kit AT91SAM7A3-EK from Atmel.

gdb-init commands:

target remote localhost:3333
monitor reset
monitor sleep 500
monitor poll
monitor soft_reset_halt

# deprecated commands for ram/flash
# monitor arm7_9 sw_bkpts enable
# monitor arm7_9 force_hw_bkpts enable

# WDT_MR, disable watchdog 
monitor mww 0xFFFFFD44 0x00008000

# RSTC_MR, enable user reset
monitor mww 0xfffffd08 0xa5000001

# CKGR_MOR
monitor mww 0xFFFFFC20 0x00000601
monitor sleep 10

# CKGR_PLLR
monitor mww 0xFFFFFC2C 0x00481c0e
monitor sleep 10

# PMC_MCKR
monitor mww 0xFFFFFC30 0x00000007
monitor sleep 10

# PMC_IER
monitor mww 0xFFFFFF60 0x00480100
monitor sleep 100

# needed for gdb 6.8 and higher
set mem inaccessible-by-default off

load
break main
continue

All went fine until i reinstalled the whole ubuntu system and the toolchain.

Now:

Loading the binary into the SRAM works fine, and also debugging works fine again. All done with arm-elf-gdb and openOCD in eclipse.

But Loading the binary into the FLASH doesn’t work at all. The old program, which is already on the flash, doesn’t even get erased.

I always get the message:

```
Unable to set 32 bit software breakpoint at address 001000b0 - check that memory is read/writable


Here is the whole output in eclipse:

I tried following things without success:

- an other uC-board.

- different projects

- old workspace-backup, which contains the whole code needed by the application - even the Atmel Lib. 

When i was reinstalling the whole system, i used for each tool the same version even the openOCD is the same SVN-release (SVN977). 

Has anyone an idea what is wrong there?

Thanks for all hints!

does really nobody have any idea for me.

i still have the problem.

which part of the tool chain fails?

is it openocd or gdb?

EDIT: what’s about the

warning: Can not parse XML memory map; XML support was disabled at compile time

(output of gdb in the eclipse-console)
