- Nucleo-L152RE with ST-Link board still attached and power from USB
- STM32CubeIDE configured as picture. Freq at 1000K to match slow speed set in the Monitor
- Also Debug Config has ST-Link Shared
STMCubeMonitor has the probe set up like this:
... it's connected and everything.
However, when I launch the debugger from CubeIDE, or I launch from CubeProgrammer, the probe immediately goes red with the [not connected ! Device not opened (5)]
In my attempts to fix this myself, I added this to my code:
#define DEBUGGER_ON 1 //REMOVE BEFORE FLIGHT
#define LOW_POWER_DISABLE 1 //REMOVE BEFORE FLIGHT
In my attempts to fix this myself, I also tried flashing my program onto the STM using CubeProgrammer. I had the same effect. While the CubeProg was attached my program ran but CubeMon said the Device was not open. I would close CubeProgrammer and the program would stop but CubeMon finally found my device.
I'm clearly in need of better understanding. My guess is ST-Link is not sharing very well. Any suggestions would be greatly, greatly appreciated.
Thx for the reply @Richard.Chvr! Yes, it is installed properly with the latest revision as shown below.
