Flashing an STM32 target with JLink probe on Linux (Arch) fails unless --disable-double-buffering is used #1891
Open
Description
Describe the bug
Flashing fails with different errors, sometimes a timeout, sometimes a LockedUp status:
Finished release [optimized + debuginfo] target(s) in 0.06s
Running `probe-rs run --chip STM32L052C8Tx target/thumbv6m-none-eabi/release/lightnote-rtic`

Caused by:
0: The page write of the page at address 0x08000400 failed.
1: Something during the interaction with the core went wrong
2: A timeout occurred.
I noticed that the address where the error occurs varies from execution to execution. I've observed 0x08000400, 0x08000c00, 0x08001c00

Flashing succeed if double-buffering is disabled:

Hello, world!
To Reproduce
Steps to reproduce the behavior:
probe-rs run --chip STM32L052C8Tx <file>
Expected behavior
Flashes with no error
Desktop (please complete the following information):
- Linux (Arch)
Additional context
Target: STM32L052C8
Probe: JLink Base
Host: Arch Linux (Intel i5/Thinkpad)
This is a J-Link Base that works very reliably with Jlink tools as well as with the workaround mentioned above.
