** [tickets:#352] Watchpoints with HLA target**
**Status:** new
**Milestone:** 0.11.0
**Created:** Wed May 25, 2022 07:33 AM UTC by Fab

Using the latest commit (0a36acbf6ac67cf6e95077aa25a001e2638f2798), an
ST-link-v2 adapter, and a Cortex-M7, I launch openocd with:
~~~
openocd -f ./tcl/interface/stlink.cfg -f ./tcl/target/stm32f7x.cfg
~~~
Works like a charm in conjunction with gdb, but watchpoints are not reported as
WP, but as breakpoints.
The reasons are:
- In src/target/hla_target.c, adapter_examine_debug_reason, the examination is
pretty shallow.
- Also, "hit_watchpoint" is not filled in the hla_target structure.
Re-using the methods in src/target/cortex_m.c worked for me.
I also tried to forcibly use a "cortex_m" target, but it didn't go well.
Below is the log when I launch openocd, which shows that we use an HLA_SWD
transport:
~~~
Info : auto-selecting first available session transport "hla_swd". To override
use 'transport select <transport>'.
Info : The selected transport took over low-level target control. The results
might differ compared to plain JTAG/SWD
Info : DEPRECATED target event trace-config; use TPIU events
{pre,post}-{enable,disable}
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
Info : clock speed 2000 kHz
Info : STLINK V2J29S7 (API v2) VID:PID 0483:3748
Info : Target voltage: 3.243973
Info : [stm32f7x.cpu] Cortex-M7 r1p0 processor detected
Info : [stm32f7x.cpu] target has 8 breakpoints, 4 watchpoints
