[gdb] target state locked in "running" after step instruction with st-util and gdb #831

alexonea · 2019-09-14T09:01:34Z

Dear developers and maintainers of stlink,

I am trying to debug a simple program for the STM32F769I-DISCO board with Stlink/v2. I am using an Ubuntu machine, st-util for the gdb server and gdb-multiarch for the client. The connection to the target and loading of the program are successful, as well as the detection of the target in st-util (at least it seems so). However, when I try to step through the first instruction (stepi in gdb), it hangs, while the target seems to enter into continuous execution mode. Verbose output of st-util reveals that indeed, the core status is running.

Attached version information and output logs.

STLink Firmware:

(taken from STLinkUpgrade 3.2.12 GUI on Ubuntu)
ST-Link ID: 0669FF575251717867092414
Firmware version: V2J32M22

Programmer/board type: e.g Stlink/v1, Stlink/v2, Stlink/v2-onboard
Programmer firmware version: e.g STSW-LINK007 2.27.15
Operating system: e.g Linux, Mac OS X, Windows (with specific version)
Stlink tools version and/or git commit hash: e.g v1.1.0/git-c722056

Reproduction steps:

Run st-util -v99
Run gdb-multiarch program.elf and connect to target, plus load the program into memory

at this point GDB cli looks like this (additional disassemble run)

$ gdb-multiarch --command scripts/debug.gdb template.elf

End of assembler dump.

Run nexti GDB command

expected result: the target executes one instruction and gdb regains control afterwards
observed result: the target enters some kind of continuous execution mode, GDB never gains control again.

Moreover, if I stop the execution with ^C in GDB, PC is shown to point to 0x00000000 or, in other cases to random addresses.

This seems to be in connection to issue #627 however, premises differ since now we are using a Stlinkv2 with a STM32F7x. I also managed to reproduce the same issue on a STM32VLDISCOVERY. This started happening after updating the firmware to the specified version above. Before the update, the step instruction command worked fine.

The text was updated successfully, but these errors were encountered:

@alexonea: Please verify if the problem still exists in Release v1.6.0.

Nightwalker-87 · 2020-06-28T23:03:35Z

ping @alexonea

alexonea · 2020-06-29T07:31:50Z

I don't have the (hardware) resources to test at the moment. I will try in a few days time. If waiting is no longer an option, the issue can be closed and re-opened in case the problem is rediscovered during testing.

Nightwalker-87 · 2020-06-29T12:33:08Z

That should be fine, thx.

alexonea · 2020-06-30T21:39:21Z

I checked with release v1.6.0 of st-util and the same firmware version of the STLinkv2 as mentioned in the issue body. No issues detected. Seems fine.

Great, so this problem seems to be resolved. Thanks for reporting and for the feedback! 👍
