SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

Newbie trouble. Debug my own board via ST-LINK-V2 in Discovery

Posted by diprog on 2017-04-19 09:44

Hello, there!
I use stm32l-discovery (with st-link/v2) with my own board. I connect via SWD (SWIO SWCLK) chip STM32F100C4T6B.
I generate first project from STM32CubeMX.
In Ac6 set in debug options my ST-LINK/V2.

Build is normal. I have a .elf file
In code navigator set breakpoint after main function in neverend while part.
When I try to debug, i get error (attach1) and next console output:
------------------------

Info : STM32F100C4Tx.cpu: hardware has 6 breakpoints, 4 watchpoints
Info : accepting ‘gdb’ connection on tcp/3333
Error: timed out while waiting for target halted
TARGET: STM32F100C4Tx.cpu - Not halted
in procedure ‘reset’
in procedure ‘ocd_bouncer’

Info : device id = 0x10016420
Info : flash size = 32kbytes
Error: timed out while waiting for target halted
TARGET: STM32F100C4Tx.cpu - Not halted

in procedure ‘ocd_bouncer’

Error: timed out while waiting for target halted
TARGET: STM32F100C4Tx.cpu - Not halted
in procedure ‘reset’
in procedure ‘ocd_bouncer’

Error: Target not halted
Error: failed erasing sectors 0 to 3
Error: flash_erase returned -304
Info : dropped ‘gdb’ connection

------------------------------
What i do wrong?
How I can start debug from main function?

OpenSUSE 42.2 x64
System Workbench for STM32 - OpenOCD (for Linux 64bits) Version: 1.13.2.201703061529
STM32L-DISCOVERY with own connected board via SWD (no reset use)

Hi diprog

As they say, ” STM32F100C4Tx.cpu: hardware has 6 breakpoints, 4 watchpoints ” .
In my opinion you have too many breakpoints in your debbung system.
You need to remove them and it will works.

Best regards

Hi

You have to connect a reset line or else use a non default openocd local script (i.e. reset_config srst_nogate) or else override the default in run/debug config with openocd option.

Yes. You are right.
The problem is newer or latest script try to use HW_RST on ST-Link V2.

I use this device for program my STM32f407vgt6 controller, and I have same issure

-----------------------
‘’Info : Unable to match requested speed 2000 kHz, using 1800 kHz
Info : Unable to match requested speed 2000 kHz, using 1800 kHz
adapter speed: 1800 kHz

in procedure ‘reset’
in procedure ‘ocd_bouncer’



Error: Target not halted
Error: failed erasing sectors 0 to 1
Error: flash_erase returned -304’’
-----------------------
for program controller i use stlink v2 mini (http://www.waveshare.com/st-link-v2-mini-stm32.htm)
By default, the microcontroller is not programed openstm32.
before modifying cfg fileQuestion

than i google some information and modifying some lines

modifying cfg fileQuestion

and result (program works good):
the resultQuestion

but debug do not work
debug errorQuestion

What can be the problem?

also st-link v2 works fine
st-link v2Question


UPDATE:

How to solve this issure:

-----------
Info : Unable to match requested speed 2000 kHz, using 1800 kHz
