Command failed with status SwdApFault

[MorganTechngs]

Describe the bug Attempting to probe-run and flash a STM32WL55JC1 returns a variety of errors with the probe connection.

To Reproduce

$ probe-run --chip STM32WL55JCIx --verbose
$ # or
$ cargo-flash --chip STM32WL55JCIx

Example This was run using standard stm32-hal quickstart main and files. Also tried empty main and that gave the same errors.

config.toml

[target.'cfg(all(target_arch = "arm", target_os = "none"))']
# Change this runner as required for your MCU.
runner = "probe-run --verbose --chip STM32WL55JCIx" # to list chips, run `probe-run --list-chips.`
rustflags = [
#  "-C", "linker=flip-link",
  "-C", "link-arg=-Tlink.x",
#  "-C", "link-arg=-Tdefmt.x",
  # This is needed if your flash or ram addresses are not aligned to 0x10000 in memory.x
  # See https://github.com/rust-embedded/cortex-m-quickstart/pull/95
#  "-C", "link-arg=--nmagic",
]

[build]
# Change this target as required for your MCU.
target = "thumbv7em-none-eabi" # Cortex-M4 and Cortex-M7a (eg F, L4, H7)
#target = "thumbv6m-none-eabi"    # Cortex-M0 and Cortex-M0+ (eg G)
# target = "thumbv8m.main-none-eabihf" # Cortex-M33F and Cortex-M35F (eg L5, U5)

[alias]
rb = "run --bin"
rrb = "run --release --bin"
rr = "run --release"

Have also tried with and without flip-link, defmt, and nmagic but no difference.

Error: An error with the usage of the probe occurred

Caused by:
    0: An error specific to a probe type occurred
    1: Command failed with status SwdApFault

Running using connect-under-reset gives the same error or occasionally SwdApWait status.

Problem was originally #27 but through some resets and restarts its now moved to SwdApWait or SwdApFault response each time.

This is using STLinkV3 built into the development WL55JC1 board. Programming using STM32CUBE is possible and works fine.

The following devices were found:

Any help would be appreciated!

Thank you for your report. Since the issue also occurs with cargo-flash and probe-rs-cli I'd assume this is an issue in the probe-rs library.

Can you please report the issue there (https://github.com/probe-rs/probe-rs) and link to this is here?

In your binary, does your main loop have asm::wfti(). I managed to get rid of this problem by commenting out that line. Hope that helps someone.
