STM32 has a debug register DBGMCU. It contains bits controlling low power behavior, c.f. RM0008 and AN4989. I have just done some experiments on Nucleo_F103RB. Previously there was no output until the target is halted. Now there is at least some incomplete output when the target is runn...
Debug access can differ. 2. Bit[24] is the T-bit and is loaded from bit[0] of the reset vector. General-purpose registers R0-R12 are 32-bit general-purpose registers for data operations. 12/91 Doc ID 022979 Rev 1 PM0215 The STM32 Cortex-M0 processor Stack pointer (SP) register ...
µVision halted the program at the start of main() since Run To main is selected. 2. The last two frames are actually SWV Exception frames and not instruction frames. Open the Exception Trace window and click on the Count column to bring SVCALL to the top. In my case, two exceptions...
