Hello,I am trying to get SBSFU working on my G071RB Nucleo board with my own test application.So far I have used the X-Cube-SBSFU examples and have the UserApp running as expected, it boots and I can run the tests. All good.I now want to replace the UserApp wit my own application and test with that.I have built SBSFU and have been able to use the postbuild.sh script to merge my application with SBSFU ok.SBFU runs, but I am getting a watchdog reset everytime it comes to execute the user firmware as below:= [SBOOT] SECURE ENGINE INITIALIZATION SUCCESSFUL = [SBOOT] STATE: CHECK STATUS ON RESET WARNING: A Reboot has been triggered by a Watchdog reset! Consecutive Boot on error counter = 5 INFO: Last execution detected error was:Watchdog error. = [EXCPT] WATCHDOG RESET FAULT! = [SBOOT] STATE: CHECK NEW FIRMWARE TO DOWNLOAD = [SBOOT] STATE: CHECK USER FW STATUS A valid FW is installed in the active slot - version: 5 = [SBOOT] STATE: VERIFY USER FW SIGNATURE = [SBOOT] STATE: EXECUTE USER

How can I correct the temperature? Is there a correction table?

Hello,i want to design a new antenna layout with the ST253911b chip.It is recommended to match the antenna across RFO1 and RFO2 to a load impedance of 10 Ohm.Do i have to change the register "RFO normal level definition register" adress 27h to 10Ohm?What happens if i set it to 1Ohm?Best regardsPeterSPX

Hello allI use ST25DV64K.If the I2C communication is normal, it returns ACK after receiving data, and after receiving the last data, it returns NACK response and issues Stop Condition.If the I2C communication is abnormal, and the master issues a stop condition without returning a NACK response to the NFC tag, will the NFC tag be able to receive the stop condition normally?Also, after the Stop Condition is issued, will the NFC tag be able to accept the next Start Condition normally?Or will it not accept the next input data until the maximum value of TCHCL or TCLCH (25ms) has elapsed?BRMorooka

I'm having trouble opening Cube supplied projects with STM32CubeIDE under MacOS.- Most ST supplied videos just say "navigate to STM32CubeIDE folder and double click '.project' file to open the project in STM32CubeIDE, but it obviously doesn't work under MacOS as it does not show '.project' file in finder.- Using 'open -a STM32CubeIDE .project' from shell opens the '.project' file in editor mode.- Using 'Open Project From Filesystem...' menu does not seem to read content of the '.project' file, as build command stays grayed out.Does anyone know, or have a pointer to a working tutorial of how to open existing, more specifically, Cube examples in STM32CubeIDE under MacOS?

I am trying to change the lower measurement threshold of this sensor so that it will only send proximity data above a certain distance. I am quite new to using ToF sensors and am not sure where to start, I have looked over the documentation and am still quite lost, any help would be greatly appreciated!

We are working on syringe volume sensing application with VL53L0X Our expected accuracy is +/- 2mmWe configured sensor in high accuracy mode with 900msec budget timeTo check stability performance of sensor over long period of time we captured 97000 sample at @ 1 sec periodicity over 27 hours period with object at fixed distance.Overall we found the sensor output is stable varying between 3 count for fixed object distance.Attached is the 97000 readings which we captured and our observation and queries.Please help us to provide answer to our queries..

Hello.I am in the process of power on my custom board. Right now I'm trying to get the USB to work but I'm stuck and don't know what to do next.I use USB midleware from CubeMX 6.1.2The moment I have everything configured and run the interrupts I get the one interrupt with flags:USB_OTG_GINTSTS_USBRST and USB_OTG_GINTSTS_USBSUSP.While handling the suspend handler my micro controller is restarting (The restart is caused by operation: __HAL_PCD_GATE_PHYCLOCK(hpcd) in usb suspend handler)I checked the voltages and waveforms of crystal lines and ulpi clk line and everything seems to be ok.Here is the USB3300 wiring diagram:ThanksPiotr

Hi,I am running into a problem where the VL53L0x will return "0" for its SignalRateRtnMegaCps value for certain range measurements. Some sensors I have it does this an overwhelming amount of the time. Some sensors I only see this periodically.I use this SignalRtn value to gauge how strong of a reading I received. The 0's happen in situations where I would certainly expect there to be a strong value for SignalRate.Does anyone knows if this "0" means anything? Or if anyone has come across this before? Thanks

Is there anybody out there who got the USB running as VCP on a STM32L552 ? We have problems to get the system running with USB attached to a PC via VCP. We used the MXCube release 5.6.1 and created a small project with USB VCP. The VDD-USB Pin is connected to 3.3V, the system boots, but USB is not detected on the PC side. We have USB as VCP working on several other processors before (STM32F4, STM32F7, STM32H7) without any issues. But on L552 there must be something different which is not working when using the same firmware handling and hardware layout. Any comments are very much appreciated.

I am trying to receive some uart input from data that is an unknown size. I should end on \r\n or on an OK or ERROR received. The issue I am having with interrupts(HAL_Receive_IT()) is obviously losing too much data. I have also tried to implement this with DMA and a buffer but could not get it working. I have looked at some of the other solutions posted as well (one by user Tesla Delorean in 2018 on streaming uart data from a different module) and another from an ST employee here: https://github.com/MaJerle/stm32-usart-uart-dma-rx-tx/blob/master/projects/usart_rx_idle_line_irq_L4/Src/main.cI do not want to use any RTOS though. Is there some really simple example of just getting the uart data and outputting it to console on another uart? Or can someone guide me on how to do this/ tell me the best/better way ? Just reading 1 byte and interrupting each time is too slow and missing too much data. Thank you.

I am working on improving the pedometer functionality on a sensortile.box device. I would like to use the regression tool provided in the Unico GUI, to use pre-recorded data patterns to configure the pedometer. The problem I ran into is, that if I load patterns into the Debug /Data Injection Tool, they are either not recognized, or the values are 0 or -2147483648 (min value of signed 32 bit int), or the program crashes instantly without error code.If I use the regression tool on my pattern folder, it does something and creates a .ucf and config file, but no matter what patterns I give the tool, the .ucf is always the same.The Patterns were tested in the MLC Tool, which accepted them and interpreted them correctly.The only reason I could think of is, that the extra motherboard is needed in order to use these tools, but I was not able to verify or disprove this assumption, so I would be thankful for an answer to that.Best Regards,K. Werner.

I am trying to explore X-CUBE-TOF1 and I have several VL53L3CX breakout boards. I'm using the latest CubeMX and IDE (6.3.0 and 1.7, respectively) and therefor downloaded both the 2.0.0 and 1.0.0 X-CUBE-TOF1 cube modules.I've selected the following software packs:The performed the following configurations: After generating the code, the directory is completely empty.Removing the software pack results in a properly generated project (but without the software packs, obviously) How can I generate starter code to use with the VL53L3CX breakout boards?

I would like to send an image of size 320x240 pixels using ZigBee mesh to the intended node from coordinator. What is the maximum range of ZigBee in mesh configuration achieved with STM32WB55 with external SMD antennaWhat is the power consumption in ZigBee mesh configuration for each node.I will have to send the image twice in a day and rest of the time all the zigbee nodes will be in sleep mode.. Is it possible to have wake on radio mechanism to keep the modules in sleep and wake up only when there is some data flow ?

I am using a LIS3DH breakout board that is exhibiting weird behavior. My I2C master is a STM32L496 board that has been tested OK with other I2C chips.StartupI2C init to 400 KHzScan all possible addresses via HAL_I2C_IsDeviceReady() loop Remember addressRead WHO_AM_I registerIf it's an LIS3DH, Write config registersIf I write 0x00 into CTRL_REG0, the next write or read is NACK'd. If I reset the MCU, the reported address from step 3 changes to 0x10. (thus the NACK)So, on power cycle, the address from step 3 is 0x30 and post-config the chip NACK's 0x30.On MCU reset, the address from step 3 is 0x10 and everything works OK. I believe writing 0x00 to CTRL_REG0 is the root cause. It seems like undocumented behavior.Anyone else see this issue?

1.I want to control a BLDC motor. Why can't I choose BLDC type in MC workbench? There are two PMSMs motor types available to pick.2.Does anyone know if the set (X-NUCLEO-IHM07M1 and NUCLEO-L476RG) would be enough to control this motor?(https://uav-en.tmotor.com/html/2018/GB_0402/34.html) We want to use quadrature encoder and torque control by FOC method. Any help would be great

I have implemented my entire application in Touchgfx and FREERTOS and using the NOR flash as the external memory device. Now, is there any way to copy the entire code stored in NOR to SDRAM and run execute from there. Just like boot loading from NOR to SDRAM for faster execution. Becuase I see some image flicker/slide effect with NOR flash and wanted to execute code from SDRAM. Is it really possible with this device ?
