Hi all.I am trying to connect 2 STM32F103C8 (blue pill board).I run a test using just ONE STM32 using SPI1 as Master and SPI2 as Slave, all configurations were working fine (FullDuplex, Master Transmite. receive only Slave....every test was fine (allways using TX and RX with interruption), this test was performed in order to check if conifiguration is ok....as all test were ok y decide to interconnect 2 STMs and I have an issue in Slave STM:Master SPI sent only one data (3), in Slave STM HAL_SPI_RxCpltCallback  is fire, so I can see the Data received (3), it is save into an array, but HAL_SPI_ErrorCallback  is fire too if Master send more than one word (16 bist).Data from Master is ok, please check the figure below:Here is Slave configuration:#include "main.h"volatile uint16_t SPI_Datos_RX[5000];volatile uint8_t SPI_NumElementos=1;volatile uint8_t SPI_RX_Data_Available=0;volatile uint16_t SPI_INDEX_RXED=0;volatile uint16_t SPI_DATA_RXed;volatile uint16_t INT_TMP=0;SPI_HandleT

Is there a second I2C bus exposed in CMWX1ZZABZ besides I2C1 pins 35&36?I would rather use second I2C than adding MUX to get all sensors connected.Thanks,Tipo

I am trying to generate a periodic signal with the DAC on the STM32G474 using DMA. There are tons of examples of this, and I´ve done the same in the past with an STM32L4 and F4 with no issues. However, I´m not sure if there is a problem in the STM32G4 line or a bug in the libraries/HAL code generation. I set up a simple example, just with a circular buffer of 2 samples at a slow rate, but I never get anything out, it generates on start a DMA transfer error and disables DMA.I have tried different pins and channels. In the STM32G4, the DMA streams are multiplexed so you can use any as long as you are not using the same for other peripherals. I tried starting the timer first, including delays, calling HAL_DAC_Start() before HAL_DAC_Start_DMA() (which is redundant). Setting a value manually to the DAC works with no problem. I have tried also using Timer2. I´m using STM32CubeIDE 1.3.1 and the code is generated with STM32CubeMX 5.6.1, the latest versions.The main.c is here, it includes all c

I bought hundreds of stm32f427vgt6 MCUs, They work abnormally—— The flash size@ address 0x1FFF 7A22 value is 0xFFFF, In theory it should be 0x0400. The MCU uid @ address 0x1FFF 7A10 of the same batch is irregular，but it should be regular according to previous data. So, are these MCUs fake ? Is there any good way to identify whether MCU is genuine or fake ?

Hi,I am currently trying out the AES Accelerator of the STM32WB55, using the HAL. It is working fine on its own, but I am unable to get matching results to MbedTLS. So Ciphertexts and Tags generated by the Accelerator are not matching those generated by MbedTLS, and decryption of Accelerator Ciphertexts using MbedTLS fails (tags and cleartext do not match).In the process of checking different configuration options, i stumbled upon the header size. STM32CubeMX forces the header size to be 1 with no apparent reason. I tried the Accelerator and MbedTLS both with header sizes of 0 and 1 (by manually changing the CubeMX-generated code, termed additional data with MbedTLS), both do not match.Is there a reason why CubeMX forces the header size to be 1?I am appending the relevant code, in this case with header size 0. Did I make some mistake somewhere? Or is there some other hidden reason to this?CRYP_HandleTypeDef hcryp1; __ALIGN_BEGIN uint32_t pKeyAES1[8] __ALIGN_END = { 0x00000000,0x000000

Hello,I've created a custom PCB with a STM32F207 controller on it. With this board I want to address different targets using SWD. My targets are a STM32F407 and a STM32L431 controller. I implemented a custom SWD interface with Timer and DMA on my F207 controller and now I'm able to talk with my targets over their built-in SWD interface. For example I can read the UniqueID of the targets or write into the flash of them. But I've got a problem with the mass erase of the flash. With the F407 the flash mass erase work fine. It took about 8 sec and then the hole flash is empty. But on the L431 it wont work. Writing into the empty flash of the L431 works fine. I take the following steps to perform a mass erase of the flash: Unlock the write access to the flash register (works, because the LOCK bit is not set anymore and I can write to the flash).Then I check if the BSY bit in the flash status register is set. When it's set, I wait until it's cleared.Then I'm clearing the ICEN and DCEN bits i

Sending display data to an ILI9341 via SPI. The ILI9341 needs 16bit words in BigEndian. When I convert the STM32 LittleEndian data to BigEndian and then send the data paket as 8bit bytes everything is fine. In order to save the conversion I tried to send the STM32 LittleEndian data as 16bit words. This works except for the very first byte of the paket: The SPI outputs always 0 for the first byte, after that everything is perfectly okay again. Reprocuded on STM32L432KC and STM32L45ZI. Any ideas?

Hello!Almost everything is in the title. Is there a way to rename the device I'm developing.When I lsusb, it says STMicroelectronics virtual COM port. How do I change that toMyDeviceName?Beside this, is there a need to get a vendor ID / product ID? In this case, how / where doI apply?Thanks,

There is a bug in the CubeMX Code Generation in STM32CubeIDE Code Generation (Version 1.7.0 updated to 1.8.0) for the STM32F767ZI. (STM32Cube FW_F7 V1.16.2)The bug was found by debugging a not working auto generated code that is using a DMA circular buffer to read from uart.In the auto generated initialization code for the hardware the ordering of the function calls was:MX_GPIO_Init(); MX_USART3_UART_Init(); MX_DMA_Init();Because DMA_Init starts the clock to the dma the dma isn't clocked when initializing the uart which uses the DMA.This leads to a non functioning dma transfer and the uart overflow error is triggered because nothing is reading from the uart peripheral.As a work arround you can write:LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_DMA1);before the block with the MX initializiation functions or you can swap the calls to dma init and uart init.

Hello,We working on custom board. We using this controller STM32745IIkx. In JTAG we connect the USART1 port, but there is pin mapping issue, so I am unable to use USART1.So instead of UASART1 can I use USART2.I am sharing its schematic THE VCP_TX and VCP_RX can I use USART2.Please guided me.

Hi,Please advise how to verify token generate by "psa_initial_attest_get_token".My test kit is B-U585I-IOT02A and test application is TFM.Thanks,QiZhang

With simulator, the screenshots can be token by F3.However, I am not sure if it is possible to download current display from target / host when debugging ?

In previous releases of OpenSTLinux, u-boot used the NAND DFU backend to write to the NAND flash in the EV1 dev board. For UBI images, this required that the image was generated using the --space-fixup flag.To avoid this requirement, I submitted a patch to add a new DFU_NAND_TRIMFFS option to u-boot (link). When this option was used, the DFU NAND backend would correctly write UBI images to flash regardless of whether --space-fixup was used.With the latest release of OpenSTLinux, u-boot no longer uses the NAND DFU backend; it uses the MTD backend instead.Is there a way to tell the MTD backend to do the same (drop trailing all-0xff pages), so that UBI images generated without --space-fixup can be used?Thank you,Guillermo

I can't connect the STM32H7XI-disco board with the PC.At first, it was connected through ST-Link.I connected to the PC using a micro Btype cable to ST-LINK V3E (CN2) on the board.However, it is not connected after the wrong version of download.I want to know how to initialize or bypass the board to put in a normal program.I will explain the current state and process of this.This was a project created from "STM32Cube" on "STM32CubeIDE".I modified the clock through the .ioc file, and after the correction, the project was built with all the error-prone parts disabled, such as the DCMI in 'image_3.'At that time, set BCM4:1 and BCM7:0 from STM32CubrProgrammerand download built project to MCU. If you refer to 'image_4, you can see that it is properly recognized on the PC.However, errors such as 'image_1' and 'image_2' occur.I hope we can connect it again somehow.Thank you for your help.

Working on a hardware design for the STM32L562VET6Q (because that's all that's left with enough memory!)Want to add an S1D13517 (Epson) display controller. Said controller is memory mapped, 16 data bits, needs CS, etc, and one address line to select register/data (indirect memory mode). FMC on F767 supports this under LCD. L5 has FMC and LCD mode, but apparently only allows multiplexed connections (A16 is first address line available.) This is consistent with multplexed SRAM (which may be all this chip can do).However, the data sheet says it does straight SRAM, and CubeMX says it doesn't (and doesn't give me the support software).Which is correct? The limitation of non multiplexed SRAM not supported seems odd, but it could be a pin limitation in the LQFP-100 chip. However, didn't see anything about that in the data sheet.What's the answer?

HiI want to use a program i made before with the new IDE 1.8. It should reveive som data with the UART2 until EOL is received. It works on time and after it throws an interrupt (loops in the void USART2_IRQHandler(void)) but doesn't call the HAL_UART_RxCpltCallback anymore.I think I tried everything, here some parts of the code:int main(void) { ... HAL_UART_Receive_IT(&huart2, (uint8_t *)Rx_data, 1); //activate UART receive interrupt every time HAL_NVIC_SetPriority(USART2_IRQn, 3, 0); HAL_NVIC_EnableIRQ(USART2_IRQn); __HAL_UART_ENABLE_IT(&huart2, UART_IT_RXNE); } while (1) { if (Transfer_cplt > 0)// Daten vorhanden { ... do someting with receive data } }   static void MX_UART2_UART_Init(void) { huart2.Instance = USART2; huart2.Init.BaudRate = 19200; huart2.Init.WordLength = UART_WORDLENGTH_8B; huart2.Init.StopBits = UART_STOPBITS_1; huart2.Init.Parity = UART_PARITY_NONE; huart2.Init.Mode = UART_MODE_TX_RX; huart2.Init.HwFlowCtl = UART_HWCONTROL_NONE

Hi.Im working with ST-SAFE-A110 together with STM32CubeExpansion_STSAFE-A_V1.2.0 in a STM32_L4.Im trying to change my local host keys after being populated. I can wrap/unwarp without any problems but I don't know how to erase and regenerate the keys. It seems I need to establish an admin secure session to have the required permissions in order to erase the keys but don't know how to do that. Same problem changing the Host Cipher/MAC keys. Do I need to do some changes in the auth configuration in the middleware? How do I establish an admin secure session?Thanks.
