HelloSince the VN920D-B5 chip is not available, I am looking for a replacement. I am looking for another system with similar parameters.Please help me.

Can you tell me what the Data field holds in ACI_L2CAP_PROC_TIMEOUT_EVENT?Photo out of AN5270:Thanks

Hi community,I have a problem where Ethernet does not work when VOS is set from scale3 to scale2 or scale1 on a customer board.Please help us solve the problem. Clock and peripheral settings use code generated with CubeMX v6.9.1. The CPU is STM32H745IIK6.The Ethernet driver used is one that has been confirmed to work by our company. For VOS scale3, the Ethernet driver works normally. (attachment file: "EthernetOK(scale3).ioc") For VOS scale1 or scale2, the Ethernet driver operates as follows. (attachment file: "EthernetNG(scale1).ioc")- Packets are being received fewer than usual and appear to be dropping.- When the packet sending function is called, the process completes normally, but the packet is not visible on Wireshark from the remote side. I previously encountered a problem similar to when the clock supplied to the Ethernet PHY was not appropriate.Is it possible that the ETH_RMII_REF_CLK (50MHz) clock becomes incorrect depending on the VOS settings?I would lik

Hello,We are using the STM32C0 in a low-power application.  We initially selected the part with 12K SRAM in case we needed to use more than 6K, but after development have found that we can make do with 6K.  I am curious if there is any power savings by moving to the 6K part.  The "Supply Current Characteristics" in the C011 vs C031 data sheets are cut-and-paste identical which leads me to believe that the extra SRAM has no impact on power consumption, in which case we would just stay with the 12K part.  However, if the copy/paste was somehow an oversight and we could save some power by switching to the 6K part then we'd consider doing that.Thanks,TG

Hi folks,I use MX to generate a code for STM32L4. I noticed, when I configure timer in one pulse mode, I cannot set OC CH1 in PWM mode with CubeMX. I could set it manually after code was generated, but it would be overwritten if I run MX one more time.Could someone explain, if it is a bug in the tool or "feature"? Cheers

I'm using STM32CubeIDE and targeting STM32H745IIK6.  When I was using the CubeMx plugin version 6.10.0, I was able to enable the temperature sensor input on ADC3:After upgrading to CubeMx 6.11.0 with FW package H7_v1110.zip, this option (as well as the two inputs listed immediately before and immediately after it) are now gone:With upgraded SW/FW:The three options that used to be listed towards the end of the page, between the "IN16" input and the "EXTI Conversion Trigger" are missing. Are they available elsewhere now?

Hello,actually, i'm using the bluetooth module BlueNRG-M2 , and i want to know the communication distance in meter please and the length of the antenna .Thank you 

I've downloaded the NFC Tap app and on my Iphone 8 it is not possible to start the FTM Demo because directly when I try to start it the strange overlay appears and then the app crashes and is not usable. It is the newest version.Furthermore, I was not able to download the App from your Homepage. It is a endless loop of logging in and jumping back to the same page. I've tried 3 different browsers (firefox, safari and chrome). All behave the same.  

Hello, Sometimes I have my stm32F7 going in hardfault_handler, so for my customers I have to display on a screen the last address where the software crashed, then I can analyse which problem occure the crash. So I want to get the value "pc" (program counter) like I can see in the Fault Analyzer of stm32cubeide. I tried many supossed solutions :__attribute__ ((__noinline__)) void *get_pc() { return __builtin_return_address(0); } orstatic __inline__ void *get_pc(void) { void *pc; asm("mov %0, pc" : "=r"(pc)); return pc; }but it only return the value of the current function called, and not the same value as in the Fault Analyzer of stm32cubeide. Is there a solution ? Thank you

I am using TIM+DMA, and the main problem is that the first value should be loaded into ARR before the timer starts, but it is not. Also, regarding length, if it should be set in bytes, it should be clearly documented in a comment for that function, which currently it is not. uint32_t val_tim[] = {1500, 1200, 2000, 3000, 4000, 5000};HAL_TIM_Base_Start_DMA(&htim2, val_tim, 6 * 4);

While using memory mapped mode for APS6408L using STM32u585 on B-U585I-IOT02A, how is the row boundary crossing handled?* If I want to write across multiple Rows in memory mapped mode, do I need to handle this manually or is it automatically handled by the memory controller?* Is it possible to write at any even address with data of any length or is there any limitation on the maximum size of data that can be written in single instructions like using memcpy?

HiI use STM32 NUCLEO-H743ZI2 development board for my project. I'm considering purchasing electronic components for the first time, and I would appreciate a recommendation for an X3 crystal that could be used in this situation.Additionally,I understand that I should leave SB44 and SB46 as they are,Solder and connect SB3 and SB4 each,Solder 5.6pF capacitors to C69 and C70 each, andRemove the 0-ohm resistor at SB45, correct?My board is currently in this state,and I plan to solder as described in the following diagram. Thank you very much for your guidance.

The wizard procedure put in my project this file <STM32U575ZITXQ_FLASH.ld> and this file <STM32U575ZITXQ_RAM.ld>.When is used the first and when the second and where is written in the project which one to use?Because in the linker section, as for Debug and  for Release configuration, olny the first compares.Thank you.If necessary, I'll post the content, but I thing the same thing is done for the over micro.

Can anyone help me with debounce code in C for Rising and falling edge interrupt??

Applies to: STM32L100xx, STM32L151xx, STM32L152xx, STM32L162xx.Hi,in order to write robust drivers, I'm kindly asking a few questions to developers who are into the silicon design. This is the 1st:ref. RM0038 Reference manual Rev 18, paragraph 27.6.1 Status register (USART_SR) vaguely says that error flag(s):"It is cleared by a software sequence (a read to the USART_SR register followed by a read to the USART_DR register)."which of the following describes the real case:0) "It is cleared by a read to USARTx_DR which happens AFTER a read to USARTx_SR, without any other access in between to the USARTx memory space*."1) "It is cleared by a read to USARTx_DR which happens AFTER a read to USARTx_SR, without any other access in between to the APBx* linked to the USARTx."2) ???(*) see 2.3 Memory map - Table 5. Register boundary addressesThank you very much in advance.

Hello everyone, I hope you are well.I'm working on a project and one of the requirements is connection to AWS, so I chose to start with the STM32H573I-DK kit, where following the "STM32CubeExpansion_Cloud_AWS_H5_V1.0.0" step by step I managed to connect to AWS, however , the final micro used in the project will be the STM32H563ZI, so migrating the example to this micro, however, when I use "provisioning_auto.bat" at the end of the execution the following error appears in the "provisioning.log":'Starting SFIProcessing license...Get RSSe status...Processing Image HeaderGet RSSe status...Processing Area 1...Error: Execution of RSS CMD failed, returned value = 0xBF9F0F0Error: Failed to Process Area Number 1 of type HError: C:\ROT_Provisioning\SM\Binary\SecureManagerPackage.sfi SFI file Install Operation Failure! Please try again.'Can anyone help me with how to finalize the port?thanks in advance

Hello,I am currently developing a Bootloader for a STM32H562. The Bootloader checks, if there is a valid application present by calculating a checksum over the application area. To avoid getting ECC errors during the checksum calculation, I disable the ECC NMI for this procedure. (see attached code snippet image "Code_CRC.png")Summary of the planned procedure:* disable ECC NMI* read data from the flash memory* enable ECC NMIUnfortunately, the NMI is still generated even though I have disabled its generation by the bit "ECCNMI_MASK_EN" in the "SBS_ECCNMIR" register.In my test case I write 4 words at the flash address 0x0800'8000. Then I write 4 different words again at this location (without erasing) which seems to cause an ECC double bit error at this location.Now I reset the processor and execute the procedure in the code snippet. I set a breakpoint at line #111.With my debugger I can verify that the "ECCNMMI_MASK_EN" bit is set to 1 (=> see attached image "SBS_Regs.png")The functi

Hello,I am using a STM32H743 with a W25Q128 external flash memory running FreeRTOS and FatFs. USB is configured for mass storage, to copy files from a computer to the flash memory. The following function is used to list all the files and directories in a directory and put them in a list:  void IndexFilesInDir(const char *path, SFileMgrList* psReturnList) { FRESULT res; DIR dir; FILINFO fno; uint8_t u8Count = 0; res = f_opendir(&dir, path); /* Open the directory */ if(strlen(path) != 0) { strcpy(&psReturnList->cFilename[0][0], "..."); psReturnList->bIsDir[0] = true; psReturnList->bHasParentDirectory = true; u8Count++; } else { psReturnList->bHasParentDirectory = false; } if (res == FR_OK) { for (;;) { res = f_readdir(&dir, &fno); /* Read a directory item */ if (res != FR_OK || fno.fname[0] == 0 || u8Count >= 128) break; /* Error or end of dir */ if (fno.fattrib & AM_DIR && strstr(fno.fname, "System Volume I

Hello,I am working with STM32CubeU5 TFM v1.5 for STM32 u585. I develop a custom loader using CAN communication. First I used MCUBOOT_OVERWRITE_ONLY and MCUBOOT_PRIMARY_ONLY setup. The CAN communication worked fine (in non-secure loader).Then I switched to swap strategy (MCUBOOT_OVERWRITE_ONLY and MCUBOOT_PRIMARY_ONLY not defined). The CAN communication stopped working. After quite some investigation I found out that the reason is that the FDCAN IRQ is not enabled (although set to be enabled). Then I found out that the reason is probably due to the FDCAN1_IT0_IRQn is not set in ITNS1 for the non-secure domain. This can be handled in the secure loader.Unfortunately, in this mode the secure loader is not used. I am not sure why, did I misconfigure or misunderstand something? Any advise how to get interrupt enabled in the the non-secure loader in this mode?Thanx.Best regards,peter

Dear all,we are trying to build a simple battery-powered BLE device. It should basically measure at intervals and advertise results only (minus the occasional update connection). With limited power resources we would expect to shut down both cores and have a 10 uA-ish power consumption, set aside the occasional advertisement- and rx-timeslots.That said, we have code running on the Nucleo-WB and a custom baord with the STM32WBMMG but with surprisingly high power consumption*. To eliminate our code as a cause, running the BLE_Beacon sample consumes around 7mA average after disabling the blue LED.Then, I enabled the  CFG_LPM_SUPPORTED in app_conf.h resulting in 2.4 mA - right direction, but still a factor away from where things should be.I then had a look at the aci_* API to interact with the BLE framework on the second core but did not find any (official) way to set CPU2 to sleep resp. wake it at advertisement interval times. As far as I understand the forum entries, the LL_CPU2 cal

Hello everyone, I am working with STM32WB55RG board to make a custom profile that sends a read request from mobile app to the board to communicate with STM32F7 via SPI. F7 contains the data that has to be sent to the mobile app. I have been trying to figure how to integrate BLE and SPI in my code. I have used the snippet codes of SPI and it works fine.It seems to be very difficult and the resources and tutorial aren't that straight forward like I wanted them to be. I am just not able to build the connection between the app and SPI.@TDK @KDJEM.1 @Issamos  @Remy ISSALYS @Remi QUINTIN Can you please explain me how to connect the mobile interrupt to enable the SPI.Thanks in advance!
