Resolved! Conflict between SMPS and LDO regulator during startup on STM32H7 microcontrollers.
I am working on a PCB design with a STM32H735IG uC, and I would like to use the integrated SMPS to provide VCORE directly, without the LDO. This corresponds to figure 19.2 of RM0468 (the reference manual). In this configuration the VFBSMPS is connect...
Resolved! [RESOLVED] Why IAR EWARM debugger resets STM32F7 in a weird way
Apologize for IAR specific question, hope someone here can shed some light on my problem. I've tried to ask IAR support, but looks like they have a long weekend or whatever.I have a bootloader at 0x08000000 and main app at 0x08008000.The bootloader ...
Good morning all, I have a board to test with n.4 L9026 in daisy chain, driven with a microcontroller STM32G0V1ET. Unfortunately there are no examples on ST website and I am not able to switch on outputs. Any idea?
// Init L9026 // 00 CHIP_ID, default // 01 CFG0, output high side // W=1,ADD=1,DATA=00111111,P=0,FR=0 HAL_Delay(2); // Set CS lo on L9026 GPIOD->ODR&=(~0x02); // PD1 = 0 data16=0b1000010011111100; SPI_Out_Buffer[0]=SPI_Out_Buffer[2]=SPI_Out_Buffer...
Why ST LINK V2 chinese clone breaks? And how to fix it?
Hi!I got my first programmer like this:https://pl.aliexpress.com/item/32844130786.html?_randl_currency=PLN&_randl_shipto=PL&src=google&src=google&albch=shopping&acnt=708-803-3821&slnk=&plac=&mtctp=&albbt=Google_7_shopping&albagn=888888&isSmbAutoCall=...
I am observing high system current (>30mA). The design uses the STM32L562MEY6P with an external 1.2v switching regulator connected to both VDD12 and VDDIO2. Should the VDD12 pins be connected to bypass caps and otherwise NO CONNECT instead? VDD = 3.3v.
Here is the power connection which is in error.
Resolved! ST-Link status UNKNOWN, failed to execute MI command.
In some situations, CubeIDE (v1.9.0) is not anymore able to handle the communication with the ST-Link probe. Disconnecting the USB cable, restarting CubeIDE, reseting the MCU, nothing allows to make it working again. The only way I found is restardin...
[NUCLEO-L552ZE-Q BD] How to change RDP from 1 to 0
Board: NUCLEO-L552ZE-Q with default setupSW: STM32CubeProgrammerAfter changing RDP from 0 to 1, which was my mistake, I can't connect the board with the program, STM32CubeProgrammer. Whenever I tried to connect, it gave me the error, "Error: ST-LINK ...
St-Link V3 SWD to stm32L452 JUST DOES NOT WORK
Cube programmer (and st-link utility) cannot find the target when I try to connect to flash a device. I am using the SWD connection to my target. I have connected T_Vcc, gnd, clk, dio & nrst on CN6 of the MB1440B mezzanine board. Cube programmer reco...
ST-Link/v2 intermittently stops working and must be disconnected and reconnected to USB port. Is there a way to fix this behavior?
We are using STM32_Programmer_CLI.exe in a production environment to load firmware. After a few loads (randomly) the ST-Link/v2 is no longer available to the software. The STM32CubeProgrammer shows "No ST-LINK detected". We must disconnect the ST-...
