Debug: cannot set breakpoint in VS Code

Hi Wes,

Yes the optimization was set to -Og. I haven't yet taken the intermediate course but I plan to once I exit a squeeze point at work.

The problem was caused a single typo in an edit I made to display_st7789v.c within the nRF Connect SDK, as suggested by this ST7789V display project:

https://github.com/JON95Git/lvgl-nrf52840-mdk-sample

The edit was this region:

#define ST7789V_INIT(inst)

static const struct st7789v_config st7789v_config_ ## inst = {

.bus = SPI_DT_SPEC_INST_GET(inst, SPI_OP_MODE_MASTER | SPI_WORD_SET(8) | SPI_TRANSFER_MSB | SPI_MODE_CPOL , 0),

[...]

Somehow the project was still allowed to build without errors, even though the init routine for the display was throwing data access errors I could only see when debugging with Segger Ozone.

After fixing the content of the ".bus" definition the system started working as intended.

Anders;
are you setting the optimization level in the build configuration to debug?

also take a look at this training on Debug to see if there is any insight there
