stm32cube mx just generate flash.ld linker script. So I create my own ram.ld linker script, also i modify system_stm32g0xx.c to point the entry point to sram /* Note: Following vector table addresses must be defined in line with linker configuration. */ /*!< Uncomment the following line if you need to relocate the vector table anywhere in Flash or Sram, else the vector table is kept at the automatic remap of boot address selected */ #define USER_VECT_TAB_ADDRESS   #if defined(USER_VECT_TAB_ADDRESS) /*!< Uncomment the following line if you need to relocate your vector Table in Sram else user remap will be done in Flash. */ #define VECT_TAB_SRAM #if defined(VECT_TAB_SRAM) #define VECT_TAB_BASE_ADDRESS SRAM_BASE /*!< Vector Table base address field.

I want create one app that with NFC read the memory of ST25DV64K-I.i try the official app ST25 and read the memory... but using the st25sdk-1.10.0 libraries.i use android studio.i can read the Tag name and UID, but i can't find how to read the memory

I am Using ST25R3914-AQWT NFC chip as a Slave Device and Renesas RL78 as Master device for SPI communication. When I tried to interface both controller MISO signal is shifted to 1.2V

For the package LQFP48 the pinout is the same. Also Pin names are the same. So is it possible ?

Hello,I am following this guide: https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_PackageI have reached step 6, but when I run bitbake st-image-weston I'm getting this error:DEBUG: Executing python function populate_packages ERROR: QA Issue: icu: Files/directories were installed but not shipped in any package: /usr/lib/lib Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install. icu: 1 installed and not shipped files. [installed-vs-shipped]Before that, I used this command: DISTRO=openstlinux-weston MACHINE=stm32mp13-disco source layers/meta-st/scripts/envsetup.shDo you know what can I do to fix this error? I have attached a copy of the error log.

Hello,I have a problem updating the Wireless Stack on STM32WB55CGU6 on a custom board. The board is basically a cloned version of the P-NUCLEO-WB55-USBDONGLE. The device is connected via SWD on St-Link/V2.FUS Version is already on v1.2 from Factory, but there is no STACK installed.Whenever I try to install a new BLE Stack, there are two possibilities:Either a ‘Error: FUS_STATE_ERR_UNKNOWN’ or everything appears to go fine, showing ‘success’. But either way, afterwards it appears there is no STACK installed.This is exactly the same for different Wireless Bundles and different Version Numbers.I tried 1.13.1, 1.13.3, 1.14.0 and 1.14.1 with stm32wb5x_BLE_Stack_full_fw.bin, stm32wb5x_BLE_Stack_light_fw.bin and stm32wb5x_BLE_Stack_full_extended_fw.binThe strange part is, that it already worked on one board, doing exactly the same thing!But it doesn’t matter how many times I try, it doesn’t work on the other boards.It is exactly the same thing when trying to update the STACK with the CLI Prog

Hi,When searching "L78M12", there are two results in ST web site. One says that "L78M12AB" is obsolete. The other one says "L78M" is active. For both of them, there are links to datasheets. One datasheet is obsolete and the other one is active. I look for "L78M12ABDT-TR". This part is referenced in both datasheets and I am confused about the state of this part. Any one who can help?Thank you so much,

when i configure spc58nn project ,there is pineditor and clock tree ,the configurtion gui. and i cant find any other peripheral configuration gui,any one know this?

I am a bit frustrated with the USART2, which is connected to the UART9 TX9-RX2 and TX2-RX9. So with sending from TX9 to RX2 everything is fine but the other way around there is a first byte = 254d inside the receive buffer. huart2 and huart9 are initialized totally equal asynchronous with the default CubeIDE configuration. huart9.Instance = UART9; huart9.Init.BaudRate = 115200; huart9.Init.WordLength = UART_WORDLENGTH_8B; huart9.Init.StopBits = UART_STOPBITS_1; huart9.Init.Parity = UART_PARITY_NONE; huart9.Init.Mode = UART_MODE_TX_RX; huart9.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart9.Init.OverSampling = UART_OVERSAMPLING_16; huart9.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE; huart9.Init.ClockPrescaler = UART_PRESCALER_DIV1; huart9.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_TXINVERT_INIT; after Init I do this in the main() routine:uint8_t cnt = 0u; uint8_t strU9Sent[6u]; uint8_t strU2Received[6u];   sprintf((char *)strU9Sent, "hello", cnt); HAL_UART_Recei

Hi,I would like to ask for help about STM product with part number F271-BAR5-T-TX. STM10F271 has details about F271-BAG5-T-TR parts but I cannot find a reference for the BAR5 code and its meaning. I would greatly appreciate any help to clarify the issue. Thanks.Regards,Louie

I have been using the ST25RU3993HPEV board for the Tag detection. Earlier the board is performing well and it was detecting tag. But suddenly reader is not detecting tag.Is there any chance for power amplifier regulator has gone bad? If the tag is kept on the surface of the antenna, it will be detected at some point.

Hi everybody, I'm trying to delete a single sector of my STM32L4P5G Discovery Board MX25UM51245G OctoSPI Flash memory but I always end up in a timeout. Reading memory by function BSP_OSPI_NOR_Read() is working as expected. I'm using the bord support code of the STM32L45R Evaluation Board. The timeout occurs within OSPI_NOR_WriteEnable() function call caused by the command HAL_OSPI_Receive(). My board is running at 120MHz. I will add the files as attachment and post the relevant functions here. Be aware I adapted the OSPI_NOR_MspInit() to match the other hardware. I used the app note AN5050 to bring the flash to memory mapped mode what is working as expected. But for flash manipulation I require the indirect mode. Does anyone have an idea why I end up in a timeout?uint8_t BSP_OSPI_NOR_Erase_Sector(uint32_t Sector) { OSPI_RegularCmdTypeDef sCommand;   if (Sector >= (uint32_t)(MX25LM51245G_FLASH_SIZE/MX25LM51245G_SECTOR_SIZE)) { return OSPI_NOR_ERROR; }   /* Initialize

Hello,I think it is easy to connect nucleo64-boards (e.g. NUCLEO-F303RE) and X-NUCLEO-IHM08M1. Is it possible to connect NUCLEO-F746ZG and X-NUCLEO-IHM08M1 in the same way?I am concerned about the size of the nucleo144-boards and whether they will interfere with the X-NUCLEO-IHM08M1 and whether the pins will fit.Thanks in advance

LSE clock is set in the Cube and initialisedAfter intitialisation the following registers are not set correctly and the LSE clock isn't calledRCC->BDCR->LSEDRIVE not set to hight event though macro calledRCC->BDCR->LSCOSEL set to LSIRCC->BDCR->LSCOEN not setThis looks to be a bug in the HAL library

I've gone over the hardware with a multimeter and all the pins have the right continuity, I've checked the design against the Nucleo-144 L552ZET6Q schematic and it checks out so far, and I've also checked the connections to the ST-LINK/V3 pins I'm using. I haven't been able to program the MCU once yet via SWD or USB (I'm mostly sticking with SWD for now).If anyone has any suggestions or thoughts, I'd appreciate any help I can get. If any additional information is needed from me, I'll do my best to provide

Would like your help just to conifrm.Due to difficulties in sourcing will this crystal work with STM32H750 ( HSE crystal ).FA-128 25.0000MF20X-K0 Epson.Thank you for your help!

Hi All,Background: during my very first experiments with the STM32 Motor Control SDK 5.Y.2 I did hear something like a two tone alarm coming from the motor when a critical overcurrent or overload situation occured. I was pretty sure at that time, there there must be some routine that uses the motor as a speaker to emit such a beep when required.Topic: With my current project it would be quite handy to be able to output a short beep in some situations without having to assemble dedicated speaker or beeper. But I could not find a piece of code in the MCSDK-Lib that is related to such a function.Question: My question is now, whether the alarm I did hear with the older MCSDK was just an artifact of the motor control. Or was this an intended functionality and got removed during the code cleanup in 5.Y.4?Has anyone used a motor as speaker with the MCSDK already? In my opinion that should be possible since a motor and a speaker are not very different.Regards Thomas

"Short" calibration of the coil and conversion to "Z: Reflection"Can anyone tell me what is being said there a bit more clearly, please? I'm familiar with the open/short/50ohm calibration procedure of the VNA and some aspects of Smith charts. But that line stumps me.

Hi!In my project I added a text area with one wildcard. I checked option "Use wildcard buffer", but left "Initial value" blank. Then in setupScreen() function I wrote some text to the wildcard buffer using Unicode::strncpy(). After starting my project in simulator to my surprise the text showed up with spaces displayed as fallback characters (?). I added some characters to the wildcard characters space was there too. I tried everything and in the end I set the initial value of the text area for some text with space in it. Then the wildcard text was rendered correctly with spaces. Am I doing something wrong or is it some sort of bug? Regards,Piotr
