(On Nucleo L073RZ devkit with target on SWD) I can easily connect and program a hex file from the stm32 link utility UI but it seems impossible from the CLI. Connection parameters are the same (Mode: Normal, Reset Mode: Software system reset) and the...

ST Link V3 SET is giving error due to virtual com port not installed in computer
I bought a second-hand stm32f429 discovery board, here is its image. I found 4 schematics on ST website (MB1075b~MB1075e), but I can't confirm which one corresponding to my discovery board. Accroding to the information shown on board , my board is DI...
The Flash of the chip can't be programmed. Mostly the error is that writing the first byte failed. But sometimes it is able to write a few bytes. It even worked like 3 times. The behavior is consistent over STM32CubeProgrammer and ST-Link Utility, an...
i want to make pc usb keyboard, do you have schematic and hex.
PC connected to STM32-V3SET via USB. PC COM3 sees the STLINK.STLINK is using CN7 UART TX and Rx lines to L041 USART2 configured pins PA2 & PA3. GND too.L041 has BOOT0 pin on a wire, to allow high or low level at reset.L041 has SWD-loaded program i...
I am designing a line-following robot that also avoids various obstacles (two digital infrared (IR) sensors), but I am a bit confused with my schematic since I am a beginner in electronics, and that is why I would like to know if my schematic is corr...
I don't really know where to inform this.Thank.
