ESP32 - QIO flash configuration vs software breakpoints

Postby ptihanyi » Mon May 06, 2024 8:20 pm

Hello!

I use ESP-PROG JTAG programmer for ESP32-WROOM module (ESP32-DevkitC) and noticed an unusual phenomenon:
If I set the module flash configuration to QIO, I cannot create a software breakpoint.
In addition, several error messages appear when connecting OpenOCD in this case:

Code: Select all

Warn : Failed to get flash maps (-6)!
Warn : Application image is invalid! Check configured binary flash offset 'appimage_offset'.
Warn : Failed to get flash mappings (-4)!
The two hardware breakpoints work perfectly, however, when creating a third - software - breakpoint, the following message appears:

Code: Select all

Error: esp32.cpu0: Failed to get flash bank (-4)!
Error: [esp32.cpu0] can't add breakpoint: unknown reason
Error: No flash at address 0x400d540e
If I reset the flash configuration to DIO, everything is OK; and OpenOCD errors also disappear.
By the way, the uploaded program works perfectly even with QIO mode, only debugging is problematic.

To reproduce the behavior I copied the base 'blink' project and switched the flash to QIO.
Of course, I don't use the extra GPIOs used by QIO for anything.

Complete OpenOCD log:

Code: Select all
