AHBAP, SWJ-DP Sticky and Read Mem Error

Development Boards MicroMod

Hi everyone,

I’m using the STM32-P103 board with Eclipse and oocd 0.2.0.

my problem is that I can’t use debugging.

I use this for OpenOCD:

gdb_port 3333

Work-area size (RAM size) = 20kB for STM32F103RB device

set _WORKAREASIZE 0x5000

interface ft2232

ft2232_device_desc “Olimex OpenOCD JTAG TINY A”

ft2232_layout “olimex-jtag”

ft2232_vid_pid 0x15BA 0x0003

script for stm32

if { [info exists CHIPNAME] } {

set _CHIPNAME $CHIPNAME

} else {

set _CHIPNAME stm32

}

if { [info exists ENDIAN] } {

set _ENDIAN $ENDIAN

} else {

set _ENDIAN little

}

JTAG speed should be <= F_CPU/6. F_CPU after reset is 8MHz, so use F_JTAG = 1MHz

#jtag_khz 1000

jtag_speed 3

#jtag_device 4 0x1 0xf 0xe

jtag_nsrst_delay 100

jtag_ntrst_delay 100

#use combined on interfaces or targets that can’t set TRST/SRST separately

reset_config trst_and_srst

#jtag scan chain

if { [info exists CPUTAPID ] } {

set _CPUTAPID $CPUTAPID

} else {

See STM Document RM0008

Section 26.6.3

set _CPUTAPID 0x3ba00477

}

jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_CPUTAPID

if { [info exists BSTAPID ] } {

set _BSTAPID $BSTAPID

} else {

For GDB:

target remote localhost:3333

break main

I got following Errors:

I tried a to reduce the JTAG speed but it didn’t worked out for me… I Have no Idea what else I should do…

So any help would be much appreciated!

First of all - upgrade to the most recent OpenOCD release (0.4.0). Then use the STANDARD (don’t modify them!) config files! In the end - if the above still fails - start thinking about another solution.

4/3!!

Today I updated to the new version of openOCD (0.4.0) and I used the unmodified cfg files.

But now it changed from SWI-DP to JTAG-DP and I do not have any AHBAP errors…

Error: JTAG-DP STICKY ERROR

Error: MEM_AP_CSW 0x23000052, MEM_AP_TAR 0xfffffffc

Is nobody out there who got the same problems and solved them? Any suggestions what it might be?

Any help is much appreciated.

I presume you are using the olimex_stm32_h103.cfg cfg file?

Reduce the jtag clock speed, eg. adapter_khz 500 (in stm32.cfg)

if you still get problems provide a full debug log, eg. openocd -d 3 -l openocd.log

Cheers

I tried to reduce the JTAG Speed to 500kHz but it didn’t help… so there is something I found in the log file:

I would really appreciate any help…

Good day,

I hope this solution is relevant to your problem. Please post a reply if you’ve managed to

solve your problem.

I’m running OpenOCD GIT (2011/03/03 commit 0123985abc88876ca8ecd03e9a5462cc8e911693)

and found errors on the OpenOCD console while busy debugging:

Error: JTAG-DP STICKY ERROR

Error: MEM_AP_CSW 0x23000052, MEM_AP_TAR 0x33333338

Error: JTAG-DP STICKY ERROR

Error: MEM_AP_CSW 0x23000052, MEM_AP_TAR 0x33333338

Error: JTAG-DP STICKY ERROR

Error: MEM_AP_CSW 0x23000050, MEM_AP_TAR 0xfd243d76

My setup is an Amonte UsbTiny connected to a STM32 (ST Cortex M3)

I found that these problems went away when I’ve increased the JTAG speed from 1000kHz to 3000kHz in

/opt/openocd_git/share/openocd/scripts/target/stm32.cfg

Line 24: adapter_khz 3000

Had the same problem with an STM32F107 on the Olimex Board. The 3Mhz fixed it 8)
