Hello!Hope you are doing well.I would like to check if I can get the thermal resistance Rthja and Rthjc information on Part no: M24LR04E-R.Let me know your input and if you have any questions!CheersMadhu

Why STM32G431 CAN get into bus off status? I cannot find the reason in the reference manual.

Hi, I'm using the STM32G030 MCU and I want to perform programming using the CLI commands. When using the STM32 ST-LINK utility and opening the option bytes window, I can see the PCROP bit which if I set, the MCU performs a mass erase when RDP bit changes from 1 to zero, which is the expected behaviour. The issue is that this bit is not found in the datasheet. Also, when I use STM32CubeProgrammer, the PCROP bit is not shown as part of the option bytes ( I only see RDP setting). Moreover, when using the STM32CubeProgrammer CLI command to clear RDP bit, the subsequent mass erase command does not work. At this stage, a strange thing is seen. If I try to clear RDP bit using the STM32CubeProgrammer CLI command, a warning is returned that RDP is already set to zero so no action is taken. BUT, if than I connect to the MCU using the STM32 ST-LINK utility and open the option bytes window, the RDP bit is still read as level 1 !?!?!?Can anyone put some light on t

Hello, I am currently using bare-metal MP13 solution in CubeIDE. I want to integrate uart with DMA. After configuring DMA settings for uart4, a following fragment of DMA init code has been generated:NVIC is not available for Cortex-A, but still its functions are being generated. My question is, how can I properly adjust MX_DMA_Init for uart interrupts without NVIC and code generation?Do you have any ideas? Thank you,Jacek S. 

Hello!What is the difference between JTRST and NRST of stm32 mcu?When using SWD, where should the RESET pin be connected? NRST or JTRST?

After installing the programmer to the system and connecting it to STLINK, I encountered this NOT FOUND error. I don't know where the problem is. Also, my programmer is STLINK_V2.My second question is, when I try to install the STLINK UNITY software, error 1605 is displayed to me and I don't know where the problem is? Thank you for your guidance.

We are working with STM32MP135FAE7 processor. We are unable to get clock, chip select spi4. Here is the pinmux for spi4 according to our board which is defined in optee stm32mp135dk.dts.spi4_pins_alt1: spi4-alt1 {pins {pinmux = <STM32_PINMUX('B', 15, AF5)>, /* SPI4_MOSI *//*<STM32_PINMUX('D', 10, AF5)>, /* SPI4_NSS */<STM32_PINMUX('F', 3, AF5)>, /* SPI4_MISO */<STM32_PINMUX('H', 9, AF5)>; /* SPI4_SCK */bias-disable;drive-push-pull;slew-rate = <1>;};};and stm32mp135.dtsi spi4: spi@4c002000 {compatible = "st,stm32h7-spi";reg = <0x4c002000 0x400>;interrupts = <GIC_SPI 85 IRQ_TYPE_LEVEL_HIGH>;clocks = <&rcc SPI4_K>;resets = <&rcc SPI4_R>;#address-cells = <1>;#size-cells = <0>;feature-domains = <&etzpc STM32MP1_ETZPC_SPI4_ID>;status = "okay";};What can be the issue and how can I debug it at hardware level and software level?

I have my own little board: with STM32U575CIT6Q (LQFP48 package). The USB is very simple and just DM (PA11) and DP (PA12) are connected. No USB-C, no USB-C Power Detector neither external chips for USB-C (as on NUCLEO-Board for USB-C-power).I want to bring-up a simple USB VCP (CDC) UART, in FS mode. But all the code (generated by CubeMX) and example codes in CubeMX drivers/demo/application download does not work:a) I do NOT want to use USB-C stuff, assuming "UCPD", e.g. MX_UCPD1_Init(); means "USB-C Power Detection"! There is not anay USB-C power detection, unit etc.b) biggest problem: when code enters call: CHECK_CAD_FUNCTION_CALL in file "usbpd_pdm_core.c" - my external debugger (ST-Link2 via SWD pins (PA13 = SWDIO, PA14 = SWCLK) is disconnected (debugger in GUI is lost).This function CHECK_CAD_FUNCTION_CALL comes from a pre-compiled LIB "USBPDCORE_NOPD_CM33_wc32.a" - what is it doing?==> how to create a simple USB FS VCP UART with STM32U575 chip? (w/o any USB-C stu

I use the OCTASPI as QSPI. So far ok (QSPI transactions work).But I have realized:a) the QSPI does not release any signals after a transaction has finishedb) it does not seem possible to use OCTASPI (in QSPI mode, maybe as well in single SPI mode on OCTASPI pins) in "multi-master" mode (see details below)The OCTASPI does not release signals (at least not SCK, DIO0..3). And not possible to verify the state of NCS signal (if another master has grabbed the bus).Regular SPI can do: see in datasheet:So, I need QSPI (via OCTASPI) also in "multi-master" mode. It means:a) all signals are released after QSPI has finished (SCK, DIO0..3 are floating between transactions - it does not)b) NCS signal can be turned into an input, or use it as an Open-Drain output (with external pull-up)c) check the status of NCS (as input or read Open Drain status) before a new QSPI transaction is launched ("not another QSPI master on the bus")Is this possible?Is this a missing feature?Most "annoying": SCK, DIO0..3 a

I am just now moving over from ESP32 to STM32 Discovery. One of the features that I like about the STM32 is that there are 3 ADC and several accessible channels.In my previous design on the ESP32 I used external ADCs and communicated with them using SPI. I'm hoping I can cut out the external ADCs.In the STM32F4 Discovery schematic it shows how the VDDA and VREF+ pins are connected so no external (highly accurate) reference voltage can be applied without cutting traces (which is not preferred).Also I have found recommendations for reading the VREF+ voltage level with software and comparing it to the reading from the ADC. This makes sense in theory and since I'm not concerned about sample rate at this point I think it is a viable option. And if there was noise on VREF+ line or the input I can take an average of many samples.I'll need to try it out for myself but wondering if anyone has experience and can recommend which method (or a different method) would work best for accurate ADC

Hi everyone! I have a STM32F412RET7 MCU and I made myself a breakout board. However when I try to upload a code I get an error: Failed to execute MI command ... load .elf.

I have recently procured a X-NUCLEO-GNSS1A1 on its own. I would simply like to use the LIV3F to test the LNA/SAW filtering along with different antennas as well. I am able to connect the LIV3F to Teseo Suite via FTDI -> UART. I can see all of the satellites and NMEA data being streamed by the receiver, but I am unable to change any settings. I need to update a couple of settings, but the LIV3F is not detected, and it is shown in Teseo Suite as a 'generic' device, instead of a LIV3F, or LIV3FL, etc.  Any assistance would be much appreciated, I feel that I've exhausted every resource I have trying to change the settings. fwiw, I have a couple of custom PCBs with LIV3Fs installed on them, and I do not have this issue with those boards. Only the LIV3F on the X-NUCLEO-GNSS1A1. 

Is there any option to control output volume in Power IC FDA802?

I see this note in the user manual for the STM32U5A9J-DKIs it possible to enable 3.3V output for the GPIO on the CN9 header by removing SB56 and jumping the 3V3 pin to IOREF, or would this damage the board or not have the effect I intend?

Hi all, how are you?. I'm making a project with an STM32F401VE and I've updated the IDE, after that there are about ten dependencies that says something related to inknown dependencies and the .ioc project doesn't opens. I read some over there and some other people had the same problem after the STM32Cube IDE was updated, currently for me is showing this problem with the version Version: 1.5.1, Build: 9029_20201210_1234 (UTC).I tried also to import the project or creating a new project but the behavior is the same. How could this problem be solved?In the meantime I will simply reinstall the IDE

I am trying to erase my STM32U575 which is on a Nucleo board (U575ZI-Q) and it connected to the computer via ST-Link V3. I can erase the chip fine using the GUI STM32CubeProgrammer, but the command line method does nothing. This is the output I get when trying to run the erase all command: ./STM32_Programmer_CLI.exe port=SWD UR --e all-------------------------------------------------------------------STM32CubeProgrammer v2.13.0-------------------------------------------------------------------After a brief pause, it finishes with nothing else printed.Any ideas?

The SATEL-VL53L8CX dev boards were all out of stock, so I picked up the LS53LX-SlL8 Light Saber Sensor VL53L8CX by Gilisymo for debugging before I build my own PCB. I am interfacing with the sensor via the Adafruit itsy bitsy nRF52840 (but have also used the xiao nRF52840 Sense and the ESP32-S3 QtPy for debugging purposes).I had previously been able to work with the VL53L5CX easily using the Sparkfun library with a very similar set up. However, using the STM32duino library I can't communicate with the sensor via my nRF52840. The vl53l8cx_set_i2c_address() function fails some of the time, and other times it will succeed but the following vl53l8cx_is_alive() function will fail. My physical set up (with this devboard) is connecting ground to ground, 3v to Vin, SDA to SDA, SCL to SCL, and the A3 GPIO pin of my MCU to the LPn pin. I have validated that the A3 pin is responsive when I digitalWrite high and low, so it should function as a LPn control pin. I am al

Hello, I noticed that using the X-CUBE-TOF Package with the STM32WL55JC Nucleo-Board has an issue with the I2C-Peripheral(I2C-2). This genrates the I2C code in the IDE. And the Sensor can be derived.while if I define the Sensor bus IO:The Generated code is without the I2C And the Sensor is not discovered.Is that normal? should I define something to make the I2C code get generated or this is a bug in the CUBEMX-Package for ToF?Thank youAmir

If I want to use the Mini-PCB of the VL53L1X SATEL, which type of plug do I need to plug that in? (I would like to label this with "Time of flight" but unfortunately, this seems to be not possible for me ;-( ).

Hello,I made a custom f746 board like it is done on the discovery board. I have only implemented SDRAM and QuadSPIFlash. I can program the mcu without any problems. The display flickers heavily  https://youtube.com/shorts/pYuCkyMqsgM?si=iGS41lJvxs_CgsnHI am trying to get an inage on the display without SDRAM to check if the basic setup with mcu and display works. Any other tips on what this could be? ThanksMartin

Hello, I am looking for a part marking for LIS3MDLTR. The part says SF 233, but am unsure if this is the correct marking. I have read ST does not post their part markings externally.

Hi,I am attempting to send AT commands via USART1 to an ESP8266-01 connected to my STM32L452RE Nucleo board. I am trying to initialize an HSE with the following settings:And the following clock configuration: My problem is that the code is stopping in the  SystemClock_Config() function call in main.c, specifically here:To troubleshoot this problem, I've tried: Connecting the ESP01 to USART 2 and 3Driving the boot0 pin to low (Putting a Jumper from pins 7-8)Additionally i've tried the LSE in crystal mode, as well as LSE and HSE in bypass modes. I have also tried using the HSI, and the commands sent to my ESP-01 are not sent at all. (Note the commands are called from the function ESP_Server_Init() in main.c)I'm relatively new into the world of embedded programming, so any help would be appreciated regarding my clock configuration to send the commands to my USART. My source code and ioc are attached.Thanks!
