STLINKV3 Mini CN3 and Reset usage
On the STLINKV3 Mini, what is CN3 used for and what are the signals? Do the two reset pins have a useful user function?No information on this is available in the current user manual.Cheers, Hal
Resolved! st-link v2-1 vs v3e - any practical difference?
Hi,Some new nucleo STM32G4 boards have simplified version of the st-link v3 (no bridging feature implemented, at leat at the connector level, I guess).Is there any benefit from having 3e st-link version vs regular 2-1 one?
Resolved! NUCLEO F401RE board shows up as "Unknown device ID! and i can't program the board?
Communications appears fine; I get the following from BlueNRG-1 ST-LINK Utility (version 2.0.0.0):ST-LINK SN : 067......ST-LINK Firmware version: V2J33M25Conncetd via SWD.SWD Frequency = 100 KHz.Connection mode : Connect with Pre-Reset.Debug in Low P...
Nucleo-G474RE: What is the intended use of JP7?
Nucleo-G474RE has JP7, which pulls down BOOT0 pin to ground when a jumper is installed, but this alone does not control boot options. What is the intended usage of JP7? Does it have something to do that Nucleo-G474RE comes with nSWBOOT0 option bit cl...
ST-LINK V1 recognizes BlueNRG, ST-LINK V2, AND V3 do not
The STM32 ST-LINK V1 connects and recognizes the BlueNRG (see STLINK-V1)for the ST-LINK V2 and V3, the STM32 ST-LINK Utility connects but does recognize the device. same for the STMCubeIDE debug connection13:38:57 : ST-LINK SN : 56FF6D067878545241190...
Resolved! How to connect ST-LINK/V2 ISOL
Posted on October 03, 2017 at 08:58I'm trying to connect new ISOL version debugger to a device I have been debugging with the old ST-LINK. I do not have 20-pin JTAG on my device (small battery operated STM32L100) and I try to get only 3V3, GND, SWDI...
Resolved! Can not set "nBOOT_SEL" bit in STM32L011F4 MCU.
Hello, everybody.I am developing one small application, using STM32L011F4 MCU. As I realised from datasheet, there are two ways to boot from flash memory:1)Connect PB9-BOOT0 pin to ground;2)Set nBOOT_SEL bit and use nBOOT0 bit instead of BOOT0 pin. A...
