Hello I’m using a STM32L4R9I Discovery board at the moment and want to have some documentation besides the demo code about the MFX µC on the board wich is in charge of e.g. the joystick and the power measurement. In the User manual for the discovery ...
We are using STM32L151VCT6A MCU. I have already programmed and worked on the boards, but for 2nd time device is not allowing to read/write the program. And even the pin numb 72 is low at the MCU.
I had my C code running on NUCLEO-F411RE last week. I downloaded it with Keil uVision and STLink driver. But, I did something when I tried to flash it today with an assembly code instead of the C code. Now, I cannot flash the device.* A pop up win...
Hi, I am trying to acquire a signal connected to PC0 with ADC using an STM32L486RG. I used this code with a nucleo evaluation board and it works fine but when i move to the PCB the voltages read by the mcu are really low. The signal in the PCB oscill...
My target is STM32F103C8T6. My project works when I generate a .bin file and upload it using the stand-alone st-link utility configured as "connect under reset". I cannot upload directly from the IDE, I get the errors:--------------------------------...
Hi All,By default, we can easily program the evaluation board by dragging the .bin file into the Mass Storage Device of the evaluation board.Unfortunately, my company has restricted the mass storage class. Therefore there is no way I can program the ...
Hi, my mcu is not showing up in st-link v2 :( Currently boot0 i low, 10k resistor to gnd. All voltages are stable on vdd and no short circuit is detected. Any tips or possible solutions to my problem?My schematic can be found here: https://gyazo.com/...
Recently I've bought two isolated probes (from mouser). After attaching them to the target I've discovered that both consumes approx. 500 uA (measures with fluke multimeter). But I'm also have older stlink/v2 isol which I used earlier, and it hasn't ...
i connected st link to my stm32 on customboard , 1 pin -> 3.3V, 7 pin -> SWDIO, 9 pin -> SWCLK, 15 pin-> NRST, 19 pin -> GND. but keil doesn't recognize mcu. I attach the image of the connection . st link was damaged or wrong pin configuration? thank...
