Hi I am using UDE STK 2021 debugger software and for that I am using PLS-UDESTK debugger(HW), for SPC58NN84E7 microcontroller  I could see the PLS-UDESTK is mentioned as NRND(Not recommended for new design) So I am planning to use AEK-MCU-SPC5LNKU with same above mentioned SW debugger. Can you any confirm me that AEK-MCU-SPC5LNK supports UDE STK 2021 SW debugger Thanks in Advance   

Hello,I hope everyone are doing well!I have implemented MQTT protocol in an STM32H7 microcontroller that is attached on a display. For that reason I have use the subscribe method in order to receive payloads from 6 different topics, which two of them has large bytes because they have JSON form. During its normal operation, it appears the exact data on the screen and it is working correctly, it stops working (ping returns "can't reach destination" and also MQTT stops working) by giving me an  configASSERT( pxQueue->uxItemSize == 0);  in the function xQueueSemaphoreTake as the figure showing below:I am not able to understand what is the problem, before that due to the reason that the two payloads was so large the xQueue was being overwritten and this configASSERT was appearing again, but the problem was that  uxLength and uxMessagesWaiting had a big number that was not normal. This problem I was able to solve it by increasing TCPIP_STACK_SIZE in lwip

I have a board with stm32f407zgt6. I'm using freertos and fatfs. The board has a connection for an SDCARD, I'm using a 4GB SDCARD with fat32.For reading, F_open, f_read, f_close, everything works. When I use it to write, f_close takes a long time and returns FS_DISK_ERR.What do you need, files, the .ioc, the sources, no problem, to help me find the problem? I tried to configure it as correctly as possible, but I think I left something behind.The write process it's in the file ESP8266_HALL.cpp, this file I put in the body of the post, because the forum did not accept the file for a reason that I did not understand, but I will not fight with the forum, I really want help.Thank you very much.PS: f_write return the correct amount of bytes written, with what I ordered to be written. the file, after the f_close error, has 0 bytes on the disk. This happens both for already existing files and for new files  /* * ESP8266_HAL.c * * Created on: Apr 14, 2020 * Author:

Can anyone please confirm that LevelX and FileX can only be used with AzureRTOS. Everything that I have read indicates as such. Both only available when AzureRTOS is enabled as well as using CubeMX.Thanks in advance!!!

Hi all, I am working on my own program using the API provided with the stm32Cubeprogrammer V2.18 to flash custom bootlader and programs over USB in dfu mode. The problem I had was when I tried to flash a custom bootloader, the function connectDfuBootloader threw this error: Error: Database cannot be found. DatabasePath = /../Data_Base/STM32_Prog_DB_0x415.xml Error: CUBEPROGRAMMER_ERROR_NOT_SUPPORTED After a few attempts I realized I had to put the Data_base folder 3 folders up from the executable file so the program can find that file. This is not a major problem but I can't find any function within the API that allows me to change that path, so do anyone knows another way to change this?ThanksKind regards   

Hi everyone, I am looking for s low-side driver that will last more than 5 years, preferably 10. For functionality, L9822E and L9823 are good candidates, and I would like to know their expected EOL. Thanks Insu

Hi,I generated the code in CubeMX and opened it in VSCode. However, I cannot run the code because VSCode cannot find main.h. I'm not sure why this is happening. I've generated the code twice, but the problem persists. The main.h file is located in the Core > Inc folder, and main.c is in the Core > Src folder. Does anyone know what might be causing this issue? Thanks! 

Dear STM32 Community,PFA for your reference.I am working with an STM32F765 on a customized board, using STM32CubeIDE version 1.17.0. I am facing an issue related to the RCC->CSR register and processor behavior.Issue with RCC->CSR: At the beginning of execution, `RCC->CSR = 0x14000000`, which indicates a normal power-on reset. However, when I run the program without breakpoints, `RCC->CSR` shows `0x00000000` after the first loop, which seems incorrect. Breakpoint Behavior: When I set a breakpoint and step through the code, `RCC->CSR` shows `0x14000000` only during the first loop, and after that, it becomes `0x00000000`(cleared RCC->CSR manually after reading). PFA for your reference.Processor Exit from While Loop: Additionally, when running without a breakpoint, the processor is unexpectedly exiting the while loop. I am unable to identify why it is going outside the loop.(with RCC->CSR value 0xd50106d2)Steps Taken:1. Printed the value of `RCC->CSR` at differ

 Is it OK to use these pins as current sinks for driving LEDs ?  

I'm tying to setup TCP server using ethernet communications (Nucleo-F767ZI) and find that I can ping the board using the router allocated IP address but I'd like to do the same using Hostname. In STM32CubeMx .ioc file, under Network Interface Options, LWIP_ENABLE_NETIF_HOSTNAME is set to 'enable' and I've set the host name I want to use in LWIP_NETIF_HOSTNAME to 'my_lwip'. However, I still find that I cannot ping the board using the hostname. I know my router DNS is working Ok because I can ping a Raspberry Pi using it's host name.I realize that in STM32CubeMX generated lwipopts.h #define LWIP_NETIF_HOSTNAME is set to my_lwip by default but I change this to 1 manually. Otherwise, in ethernetif.c, the statement netif ->hostname - "my_lwip" is not enabled.I think mDNS has to be enabled in LwIP. However, under MDNS/TFTP tab in CubeMX, LWIP_MDNS is always disabled and there is no enable option in the drop-down list.  I've seen a post that suggests to enable LWIP_MDNS, LWIP_UDP and

I am using SPI2 and SPI3 with DMA1 to write and read to/from peripheral chips. This works fine most of the time. At the same time I am using the stop mode to save power. Now in some cases just after leaving the stop mode, the next DMA transfer does not work. The transfer is started but the complete-interrupt-routine is never called. And when checking the registers the half transfer bit is not set. A reset of the DMA(LL_DMA_DeInit(DMA1, LL_DMA_STREAM_ALL)) in this case seems to not resolve the problem. I have to reset the whole device to resolve it.DMA and SPI transfers are setup before each transfer.LL_SPI_InitTypeDef SPI_InitStruct; //Structure containing the settings for SPI2 LL_DMA_InitTypeDef DMA_InitStruct; //Structure containing the settings for DMA1 NVIC_InitTypeDef NVIC_InitStructure; LL_DMA_DisableIT_TC(DMA1, LL_DMA_STREAM_2); LL_DMA_DisableIT_TC(DMA1, LL_DMA_STREAM_5); LL_SPI_Disable(SPI3); LL_I2S_DeInit(SPI3); LL_SPI_StructInit(&SPI_InitStruct); SPI_InitStruct.Mode = L

Hi. Looking to use E-L9823 as a replacement in a legacy design.The datasheet states pin 21 is not connected. Looking to confirm it is a true "no connect" internally on the part.  On our existing PCB it will be tied to +24V. Thanks.

Hello,I want to use the security features included in the TFM in my application, I have followed UM2851, now,I have a better understanding for TFM and I succeed to implement it in STM32U585, to go further I want ot implement my own non-secure application and to interact and use secure services via PSA APIs, I have searched all the web for that, but I didn't find a hint.Any explanation or a hint, please ! Thank you.Regards,ZK.

Hi, We are developing a product/device that is mounted on a machine/vehicle that generates vibrations when in the ON state. We need a sensor that can 1.. Detect vibration start and stop while the device is stationary, with good accuracy, to determine when the machine is ON and for how long.2. Differentiate between vibration and actual motion, meaning it should detect when the device is no longer stationary and has started moving in any direction in on condition with vibration.3. Detect motion in the OFF state, where the machine is off (no vibration), but the device itself has started moving and trigger an interrupt to alert the MCU. Note: We can measure and predefine the acceleration threshold that should be considered as vibration. Is there a sensor with an internal mechanism that can directly provide output to differentiate between vibration and motion? Thanks, Jay

Hi,I am evaluating/learning the SBSFU application example on STM32WBA55CG and having issues getting it up and running. Below is the screenshot of the example log:To begin with, I want to be able to do the following.1. Flash the bootloader and flash the application.2. Reset and bootloader validates the image, all verification pass.3. Bootloader now allows the application to launch.I have made a few changes to the project to disable security features for simplification. All changes are contained to the below files (attached) and disabled FLOW_CONTROL(via flags).  And I have removed the static protection check calls from boot_platform_init( ), inserting the code snippet below as unable to attach the file.int32_t boot_platform_init(void) { #ifdef MCUBOOT_EXT_LOADER GPIO_InitTypeDef GPIO_Init; #endif /* MCUBOOT_EXT_LOADER */ /* STM32WBAxx HAL library initialization: - Systick timer is configured by default as source of time base, but user can eventually implement his proper ti

My controller uses the STM32U575 chip. I followed the recommended design for the SMPS using the same inductor and XR7 capacitors as recommended in the reference design. I built up 4 boards, the first three boards worked properly without issue. After reset, I switch from the LDO to the SMPS using the same code as is used in the various examples. No issues with 3 of the boards. On the 4th board, the wait loop for regulator ready after enabling the SMPS times out. I added code to switch back to the LDO if this happens and display a message that the SMPS has a problem (via the serial port to my computer). The processor and code runs properly from the LDO, but uses more power which is an issue as this is a battery operated device.The power to the chip is a regulated 3.3v. I tried replacing the inductor, problem still exists. Not much to the circuit. I have the two 2.2uF caps placed next to the pins 49 and 98 (using the 100 pin LQFP package). After reset, to save power, I program the CPU clo

If the resistance value of RLimit is set to 14Ω to 22Ω, how do you calculate the heat generation of the resistor?Is 0.1W OK for other resistors?Also, can you provide the BOM for the evaluation board (STEVAL-EFUSE01)?

Some strange behaviour that I can't explain but like to understand :I am using an e-paper display via SPI, and to conserve power during sleep, I power down the display via a FET.After waking up, I enable the power to the display, then initialize the SPI to talk to it.  gpio::enableGpio(gpio::group::enableDisplayPower); MX_SPI2_Init(); gpio::enableGpio(gpio::group::spiDisplay);  However, this triggers a hard fault inside MX_SPI2_Init();If I add a 1ms delay between turning on the power to the display and enabling the SPI, then the hard fault never appears.. gpio::enableGpio(gpio::group::enableDisplayPower); HAL_Delay(1); MX_SPI2_Init(); gpio::enableGpio(gpio::group::spiDisplay); Of course, if I debug/step through MX_SPI2_Init(); the hard fault doesn't appear as this is also adding delays..Any idea what is going wrong or how I could further investigate ?

Hello,I am currently designing a battery-powered device that incorporates the STUSB4500. I have a question regarding the I²C pins: specifically, whether it is safe for these pins to be pulled up (via the system microcontroller’s pull-ups) when no voltage is present on VBUS or VDD.In my design, the primary microcontroller can be powered on even when the USB power is absent, which means the I²C lines would be driven high before VBUS or VDD is applied to the STUSB4500. I have reviewed the datasheet, but it does not clearly state whether the operating or maximum ratings for the I²C pins depend on VDD. My assumption is that it should be acceptable, but I wanted to confirm to avoid any potential issues.Any guidance or confirmation you can provide would be greatly appreciated. Thank you for your time and assistance.Thanks!

Cube MX: After RTC configuration with "activate clock source" and running the Cube generated Code  the RTC wont start.TheCube MX generated code  is missing to set the RTCAPBEN Bit in the RCC->APB3ENR Register.I found out that the  "stm32h5xx_hal_rtc.c"  hal  driver  doesnt work correct.:The driver states:   "Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_RTC forPeriphClockSelection and select RTCClockSelection (LSE, LSI or HSEdiv32)(+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function."This is called by the Cube output but this doesnt set the RCC Clock bit for the RTC to "1" . It stays "0"Workaround:   Set the RTCAPBEN Bit   in   RCC->APB3ENR  manualy. Regards Henry
