ESP32 - QIO flash configuration vs software breakpoints
Posted: 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:
The two hardware breakpoints work perfectly, however, when creating a third - software - breakpoint, the following message appears:
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:
Many thanks for any suggestion!
