The development board is STM32H757I-EVAL which has a ST link V3 on it,but after I download my program (just once) and update the firmware, it cannnot work correctly.Here is the situation when I try to debug it:
I purchased a 32F469IDSICOVERY board and I connected it to the PC using a Type A - MINI B cable to the USB STLINK port. The board is powered normally (LD5 is RED) and the demo application worked fine but the board itself is not detected on the PC at ...
I am having trouble communicating with a STM32F042K6T6 microcontroller (on a custom soldered board) via a ST-LINK V2. Whenever I try to connect I receive the error: “Cannot connect to target!�? The STLink V2 does register and I can see it in the soft...
Every once in a while when remote debugging I wind up with not being able to set HW breakpoints. There's no clear indication of when this will happen, and I'm typically only setting a single break point. If I disconnect the USB to the STLink V2 fo...
I was normally using STM32CubeIDE V 1.3.0 and St-Link was working.The St-Link firmware is updated.The St-Link Utility (V 4.4.0.0 and V 4.5.0.0) finds and connects to the St-Link correctly.Whenever a new IDE version becomes available, will the user ha...
Hi there,I am using STM32CubeIDE 1.3.0 with STM32L152x MCUs. When using ST-Link GDB Server, STM32CubeIDE insists on updating Stlink firmware to the latest version (Now is V2.36.S7). After that I get the following errors:ST-LINK SN : 49FF7606837056521...
Hello, I'm designing an interface board with a STM32F469I-DISCO board, and I would like to know the distance between holes and Arduino connectors (CN5, 6, 7, 8), in order to perfectly fit my interface board with the discovery board. The only drawing ...
Hey, iam working with a STM32 L432KC with an ST-Link onboard.Iam am planning to create a PCB with the same chip and iam wondering how i could programm/debug it.I read through the Instructions and i think SWD is the right thing for me.I have a STM L45...
Hi STM Team,We are trying to flash code to STM32H745 through SWD interface. However, after multiple flashing cycles to STM, we unable to detect device in 2 or 3 boards.The below are list of the observations of that scenario.Once we give 3.3V supply t...
I can't imagine for pre-production to have to tie boot to vcc or the like as it is described on the discovery boards. Would be complicated to do this and will have to introduce additonal circuitry like a switch or rc circuit. If so can someone provid...
