Hello community,since I updated the STM32 Cube IDE the following problem is displayed when entering the run or debug session.WARNING: CPU random generator seem to be failing, disable hardware random number generationWARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffffff 0xffffffffffffffHave you had this before and possibly already a solution for it?with kind regardsTim

USB_ResetPort function is called in USBH_Process in HOST_IDLE state after USBH_Delay(200U); this results in 300 ms delay usb application.Is there any way to reduce this time in stm32 USB applications.This function is after a USB connection. Is there any way to remove this delays in USB_ResetPort funciton.HAL_StatusTypeDef USB_ResetPort(USB_OTG_GlobalTypeDef *USBx) { uint32_t USBx_BASE = (uint32_t)USBx;   __IO uint32_t hprt0 = 0U;   hprt0 = USBx_HPRT0;   hprt0 &= ~(USB_OTG_HPRT_PENA | USB_OTG_HPRT_PCDET | USB_OTG_HPRT_PENCHNG | USB_OTG_HPRT_POCCHNG);   USBx_HPRT0 = (USB_OTG_HPRT_PRST | hprt0); HAL_Delay(100U); /* See Note #1 */ USBx_HPRT0 = ((~USB_OTG_HPRT_PRST) & hprt0); HAL_Delay(10U);   return HAL_OK; } #[STM32 MCUs]​  #USB​ 

Hi!I'm using the LaunchPad CC2642R1/CC2652R1 with the accelerometer LIS2DH and i tested the "who am i" (0x33) register to validate the protocol but when i tried read another register i had the same response that "who am i" (0x33) register. Could you help me with this problem or give me some ideas to solve it?How can i set up the accelerometer? I can't read any register other than who am i (this register is shows in each reading).Thank you in advance.Best regards,Tania

Hi, I'm trying to run a USB host mass storage on an STM32F750. After building the project in STM32Cube V 1.11.0 I have in "usb_host.c" after the line" Appli_state = APPLICATION_READY;" the code "res = f_mount(&USBHFatFS, USBHPath, 1);" written, but "res" was always "FR_DISK_ERR". I had tested this way in Nucleo-H723 and seen that it worked. I decided to test with another Stm32Cube version. I had the same problem with version 1.9 but with version 1.8 it works without problems.Is this a HAL_Library issue and is there a way to solve it?I defined my project in version 1.11.0 and prefer to continue developing it with this version.

Hi all,I am developing an application using bare TCP and UDP connections.Since the new HAL implementation now uses custom PBuf allocation for Rx memories, I thought about killing the PBUF_POOL since it does not seem to be used anymore now.I started by testing my application with statistics enabled and indeed, the usage count of memp_stats_PBUF_POOL stayed at zero all the time.Setting PBUF_POOL_SIZE to 0 reduced my RAM usage as expected and the application is still running normally.Am I missing anything here? Are you guys aware of some pitfall I did not see or do you think I am safe so far?

From RM0456-stm32u575585.... Flash section 7.3.8:"... up to256 Kbytes (32 pages) per bank feature an increased endurance of 100 kcycles, that can be used for data storage that usually needs more intensive cycling capability than codestorage. Any Flash page can be chosen to be cycled more than 10 000 times (up to 100 000 times). It is the application responsibility to limit the size of the Flash area cycled more than 10 000 times to 256 Kbytes per bank."Perfect, 100k cycles is good for our use-case...But I've been unable to find any registers, or any other documentation/notes/etc, that explain how to enable this, or how to select it, or really anything explaining it at all.So.. How does this work?And how do I enable this?

Sorry for the I'm too stupid to figure this out myself question, but couldn't figure out how to do this myself. In CubeMX Pinout & Configuration under software packs, I can install MEMS support, add a LSM6DSO (and required support elements) using i2c. In the Software Packages I can configure the mems and the LSM6DSO (including the SD0/AD0 pin for LSB of the address). But, how does one add a second LSM6DSO to the project? Configuring the second slave address looks easy enough, but I need a second sensor instance first. Do I have to manually replicate the generated code used to create the first instance or is there some built-in way to "give me another i2c device with this configuration" option?

We are migrating from LSM6DSR to LSM6DSOX. In LSM6DSR the nominal timestamp resolution used to be around 25 μs. And we used to get 52 samples/sec from the FIFO.However, in LSM6DSOX with a similar setting, we are getting a resolution of around 18 μs. And hence sample has gone up to 72. What should changes be made to get similar samples as LSM6DSR

Could you kindly share any reference schematics for SPI EEPROM M95P32-I interfacing with STM32 MCU preferably STM32U585?

Hello,I am looking to use the LTDC (LCD-TFT) feature to interface with a TFT display and potential touch controllers (CTP). I am uncertain on the requirements to interface with it and wanted to confirm a few details.I have written software (generated by TouchGFX) that works with the STM32H7B3I-EVAL evaluation board. It utilizes a Rocktech display (RK070ER9427-CT). For our application, we want to use Rocktech as well, but just a smaller screen. Therefore, we are using their RK043FN66HS-CTG. The only mentioned difference is that the 9427 utilizes a different touch controller than the 66HS, so a new driver for that will have to be written. That I understand. I also understand that the pinout is different between the two displays, but they both still have the common pins (R0-7, G0-7, B0-7, HSYNC, VSYNC, DE, CLK).What I am unsure of is if there's a "LCD-TFT" driver that's device specific. For example, if I have a firmware working with the 9427, then change the resolution in the LTDC configu

Hi,I am wondering if it is possible to internally connect two GPIO pins by software, not using wires.Thank you

Hello communityI'm having issues with the STEVAL - MKI109V3 board and the Unico GUI. There is no driver identified for the board. I've tried installing the driver for Windows 8, which gets identified but when I try to open Unico GUI, I get an error message stating that it can't connect to the board, and the program closes.After some investigation there are more people that have had this issue, but I have not found a solution that works for me. Has anybody had experience with this and found a solution?

How can I flash matlab code in stm32cubeide for the board Nucleo-g071rb. Is there any way to flash matlab code? If there, then please send me the procedure.

Hi!I am using STM32MP157C-DK2 board to create an application on the screen (using GTK library). My idea is to start coprocessor firmware from the A7 application with the following commands (system commands):int main (int argc, char **argv) { GtkApplication *app;   system("su root -c 'echo core_communication_new_CM4.elf' > /sys/class/remoteproc/remoteproc0/firmware"); system("su root -c 'echo start' > /sys/class/remoteproc/remoteproc0/state");   app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE); g_signal_connect (app, "activate", G_CALLBACK (Window_info), NULL); status = g_application_run (G_APPLICATION (app), argc, argv); g_object_unref (app); return status; }With these two system commands, I want to boot the M4 firmware (core_communication_new_CM4.elf). Then, I initialize A7 program (probak_GTK) with the following command:su -l weston -c "/usr/local/probak_GTK"However, when I run the A7 application, I get the following message in the Linux

The code is generated by CubeMX. And every time program run into HAL_TIM_Base_Start_IT() like the figure below, the system will block in Default Handler. However, the TIM2_IRQHandler is defined in stm32g4xx_it.c. Does anyone have idea why it doesn't work? I also attach the code.

We're planning a design that uses the STM32U5 with built-in SMPS. Our device also uses USB, and the U5 packages we have are ones where VDDUSB is bonded to VDD so we must set VDD = 3.0-3.3V for the USB transceivers to work.We have other devices on our PCB that can operate at lower voltages to save power and I was wondering if instead of tying them to VDD if we could tie them to the SMPS output (which I think is on VDD11 and I think would be the same voltage as whatever VCORE is configured to in PWR_VOSR - so somewhere around 1V).Is this a really bad idea? My gut says this might be a really bad idea, but I am wondering if it is possible.Thanks,TG

I'm working on a project using a STM32H747XIHx dual core processor.  I believe I have the latest STM32CubeIDE and STM32CubeMX tools.  How do I configure CubeMX to generate GPIO initialization code for my I/O signals?
