Hello, I am working on a product with dual banks enabled. In each banks, there are one bootloader and application. In bank1's bootloader, if new application arrived, it will update bank2's application and then reset and boot from bank2. I meet a problem that the boot from bank 2 is not saved after power off. The code always boot from bank 1, after it lost power. In design, it should boot from the same bank as previous, while there is no firmware update. Attached my code for setting OB_BFB2_ENABLE after firmware upgrade.Thank you for assistances. Melfice

Hi.I'm using a STM32U5A5 MCU to communicate with a FLASH device through OCTOSPI.Flash is connected to port P1, and all signals are controlled by OCTOSPIM / OCTOSPI1 MCU hardware.I'm sending command "0x06" = WRITE_ENABLE, and after that I need to check that bit "WEL" (Write Enable Latch) is set in STATUS register. Nothing exotic here, just regular FLASH operations.Reading device status register is performed by sending command "0x0F" = GET_FEATURES with 8-bit address 0xC0 = "STATUS". Device will ouput STATUS value on the next 8 clocks.What I see is that function HAL_OSPI_AutoPolling() seems to be reading 1 extra byte :The first 06 command is my WRITE_ENABLE command on 8 clocks.The next 0F C0 command is isssued by polling. Note the 2 bytes "02 02" in output. Polling stops immediately because condition is met. Total is 32 clocks, while it should be 24 clocks only.If I don't use HAL_OSPI_AutoPolling() but HAL_OSPI_Receive() to manually read once the STATUS register, I have the expected sign

STM32L151RET6Is the RTC affected by the microcontroller reset?The system is placed in stop mode and is reset every 2 seconds by the watchdog.After 24 hours of operation, I find a delay of approximately 20 seconds.If I do not use stop mode and let the system run normally, these delays do not occur.It behaves as if the microcontroller reset affects the RTC.Has anyone else encountered this situation?

Hi,I ported example projects from en.x-cube-safea1\project\NUCLEO-L476RG for MbedTLS cryptolib for use on my B-U585I-IOT02A Discovery Kit. The STSAFE-A110 is powered correctly and NRESET is pulled high. It never errors on writes to the device, but all reads that execute the StSafeA_Receive function in stsafea_service.c return STSAFEA_COMMUNICATION_ERROR. In fact, it's very specifically always happening here (code snippet below) where after calling StSafeA_ReceiveBytes and getting STSAFE_BUS_OK, it is masking the header value with the inverse of STSAFEA_CMD_HEADER_RMACEN which always turns STSAFE_BUS_OK (0x00) to 0x01 which is STSAFEA_COMMUNICATION_ERROR. Any idea what I could be doing so that I can get past this?Thanks!if (status_code != STSAFEA_BUFFER_LENGTH_EXCEEDED){if (status_code == (StSafeA_ResponseCode_t)STSAFEA_BUS_OK){status_code = (StSafeA_ResponseCode_t)(uint8_t)((uint8_t)pTLV_Buffer->Header &~(uint8_t)STSAFEA_CMD_HEADER_RMACEN); <---- ***

Hi, I'm trying to get the VL6180 Time-of-Flight (ToF) proximity sensor working with the SAM E54 Xplained Pro evaluation kit. Hardware Setup: Board: SAM E54 Xplained Pro Sensor: ST VL6180 ToF Module IDE: MPLAB X v6.10 (Linux x64) Connection: I2C + GPIO Current Status: SERCOM3 is connected to SDA on PA2 and SDL on PA23 The external interrupt (GPIO 1) is connected on PB08 GPIO 0 is connected on PB09 Using the VL6180X API (v2.3.1) Goal: Get the VL6180 working via I2C Operate the sensor in interrupt mode to read sensor data I attempted to use the VL6180X API (v2.3.1), but it needs to be ported to the SAM E54. I'm struggling to understand: Which parts of the API need modification for the SAM E54? How to correctly implement I2C communication with the VL6180 using the API? How to configure and handle interrupt-based operation on the SAM E54? Are there any example projects or resources that could help with this setup? Any help or guidance would be greatly a

Hello,i am wondering why i can't find any information how fast the different SRAMs are.For Flash you have to configure waitstates, to setup the speed according to the CLK, but not for SRAM.I guess, because there is a dCache installed, the SRAM does not support full speed access or single cycle access. So the question is, how fast is the SRAM? best regards

hi there,i'm currently working on a project with the STM32WB1MMC, which is (as far as i know) based on a STM32WB15CCY.in final configuration there should be 9 services (incl. GAP and GATT) with all in all 17 characteristics.in now configured my 5th own service and encountering the following log outputi saw in the code that error 0x98 means BLE_STATUS_OUT_OF_MEMORY.after some recherche this leads me to the assumption that the gatt db size may be too small for my needs.now my question: what possibilities do i have to get my BLE configuration into this module.i tried increasing CFG_BLE_NUM_GATT_SERVICES, CFG_BLE_NUM_GATT_ATTRIBUTES and CFG_BLE_ATT_VALUE_ARRAY_SIZE but i can not add the desired services.in some cases the module does not even start.how can i determine the macimum VALUE_ARRAY_SIZE?is it possible to give the module more ram for holding the gatt database?thank you for your helpgreets peter

Using Workbench 6.3.0.Creating an "inverter" board for a custom board which uses a 25MHz crystal. Only 8, 24, and 48 MHz crystals are offered in the dropdown. Can I edit JSON file to "clocksource": "25_crystal"? If not can I edit the CubeMx clock? Can MCSDK firmware be made to work correctly with a 25MHz clock?

  Hi everyone!I have some questions related to the STM32F407 board and CAN protocol  Does the STM32F407 have an integrated CAN transceiver? If yes, how can I identify it in schematics and where can i find the schematics? If no, what external peripheral should I use to integrate one? Does the STM32F407 support CAN FD? I want to use loopback mode to get started with the CAN protocol, but I don’t know where to begin. How should I proceed?

I am working on getting a new board design with a STM32MP153F to boot from parallel SLC NAND flash.  The flash chip is 1 GB, using the FMC interface with 16-bit I/O.  What happens when writing flash via STMCubeProgrammer is the first 2160 bytes of each page are written correctly, but after that byte 2160 is repeated until the end of the page, including through the OOB part of the page.  The page size is 4096 + 256 bytes.As an example, I tried programming ARM Trusted Firmware at the beginning of flash.  If I read back a page from u-boot using the nand dump command, the first 2160 bytes match exactly what is in the file.  The remaining 2192 bytes will contain the same byte, whatever byte #2160 was.  This happens for every page written.  I get the same result if I write a page from the u-boot prompt using the nand write command.For the device tree setup, I am following the STM32MP157A-EV1 as an example.from the output from "nand info", the u-boot fl

Hi all,I'm having problem implementing a function to change the baudrate during runtime. I've read all the other topics about it and tried the proposed solutions but couldn't get it to work, maybe I missed something.I use DMA for the UART which might also change the way things have to be handled.Here's my code, basically a copy of the MX_USART1_UART_Init function:  void MX_USART1_ChangeBaudRate(uint32_t baudrate) { while (__HAL_UART_GET_FLAG(&huart1, UART_FLAG_IDLE) == SET) { // wait for UART to be idle } huart1.Init.BaudRate = baudrate; if (HAL_UART_Init(&huart1) != HAL_OK) { Error_Handler(); } if (HAL_UARTEx_SetTxFifoThreshold(&huart1, UART_TXFIFO_THRESHOLD_1_8) != HAL_OK) { Error_Handler(); } if (HAL_UARTEx_SetRxFifoThreshold(&huart1, UART_RXFIFO_THRESHOLD_1_8) != HAL_OK) { Error_Handler(); } if (HAL_UARTEx_DisableFifoMode(&huart1) != HAL_OK) { Error_Handler(); } }  I've also tried calling DeInit / MspDeInit before

Hello!New to the STM controllers, failed to realize that PA13 was necessary to connect the debugger and was quite dismayed to realize my mistake after looking to program it as a GPIO. I have tried connecting with the IDE and Programmer alike, both with BOOT0 (PA13) to Vdd and without. My latest attempt is shown below which I found another thread about -- even with PA13 shorted to 3.3V and shorted to GND I see the same result -- have I killed my poor STM? I'm using the NUCLEO-G031J6 while I get accustomed to this microcontroller. Any advice would be greatly appreciated! Thanks

I've been diving in various rabbit holes and I've come to the issue of alignment and pointers. Thus, I enabled -Wcast-align. It has flagged the HAL for the ADC DMA startup here static uint16_t adc_buffer[ADC_BUF_SIZE]; HAL_ADC_Start_DMA(hadc, reinterpret_cast<uint32_t*>(adc_buffer), 6);This is due to the fact that my buffer is a 1/2 word array but this DMA function accepts only a word array. Yet, I've told the DMA that I am using 1/2 words so it knows how to perform the access. And I think this type of cast will be OK even for alignment issues since 16 bit access will always be aligned on 16 bit or 32 bit buffers.So is this a case of knowing that it should be fine and disabling the warning here?

I upgraded my MacBook computer and installed the latest STM32CubeIDE 1.17 like many other people reporting the new warning that has appeared with the 12.3 toolchain.  I have an STM32F413 project I have been working on for a few years which uses an RTOS and TouchGFX (if it matters).  I followed the "fix" in the other posts about updating the linker file to the latest version.  The Debug build no longer has the warning so that is great.The issue is with the Release build.  Any optimization setting other than None causes the warning which the Release build has a size optimization enabled.  What is the process to get rid of the error other than supressing it which is not really a "fix"?  I figure the optimization is changing the permissions on the memory regions and overwriting the linker file settings.  Is there a proper method to prevent this?  I am using the latest default STM32F4113VGTx_... linker files for this project.-Tim

Hi, I am using the STM32G0B1CBTx on the STM32CubeMX and setting the I2C1 for SMBus-two-wire-Interface. I want to disable the timeouts but I noticed that when I do so, the clock timeout enable (bit 15 of I2C_TIMEOUTR register) is still high. Looking at the generated timeout value to be written in the register (0x0000830D), it shows that indeed, the STM32CubeMX is enabling the timeout even though I selected Disable. Below is a screenshoot showing this. Is this a bug in MX ?  

Dear,I am planning to use an OCXO (Taitien NI-10M-2503) as the external oscillator (HSE) for synchronizing the MCU to a highly accurate clock source. The OCXO provides an RF output with a sine wave swinging between -2V and 2V.According to the STM32H533 datasheet, it appears that the input signal on the OSC_IN pin must not exceed Vdd or fall below Vss. In my case, Vdd is 3.3V, and Vss is ground.I would like to seek your guidance regarding the following:Based on the datasheet, my understanding is that directly connecting the OCXO output to the OSC_IN pin would not work. Could you confirm if this is correct?Would it be necessary to use a circuit such as a bias-T to condition the signal before feeding it into the OSC_IN pin?Are there any example circuits or application notes available for this type of setup?If there are alternative or better approaches, I would greatly appreciate your recommendations.Thank you very much for your time and assistance. I look forward to your advice.Best regar

Hello,In my project, the initial Bluetooth scanning time (I am using STM32WB5MMG) takes around 10 seconds due to the GAP discovery procedure. Is there a way to reduce it to 5 seconds or less? I have tried adjusting the scan interval and scan window values, but they don't seem to make a difference—the scanning duration remains 10 seconds. Even if I need to manually terminate the scanning midway, I would like to know how to achieve a shorter scan time.Thanks
