Debugger / Compiler

OpenOCD

• Installation

$ sudo apt update
$ sudo apt install openocd

• You can refer to directory to get some configuration file for debugger

  $ cd /usr/local/share/openocd/scripts/board
  $ cat stm32h7x3i_eval.cfg

• You should see something like this:

source [find interface/stlink.cfg]

transport select hla_swd

source [find target/stm32h7x_dual_bank.cfg]

reset_config srst_only

Compiler's option

• When we are linking libary for stm32 target, we may need to set the flag by ourselves, we can refer Makefile generated by CubeMX

• For example

-mthumb -mabi=aapcs
## For cortex M4
-mcpu=cortex-m4
-mfpu=fpv4-sp-d16
-mfloat-abi=hard

## For cortex M7
-mcpu=cortex-m7
-mfpu=fpv5-sp-d16
-mfloat-abi=hard
