Hi everyone,Is anyone can explain the SLEEPDEEP bit from SCB->SCR with more information than the pm0214 stm32 cortex-m4 reference manual?Controls whether the processor uses sleep or deep sleep as its low power mode: 0=Sleep, 1=Deep SleepWhat i want to know exactly is why do we need to reset this bit when waking up?If you refer to the image attached, taken from HAL_PWREx_EnterSTOP2Mode, first line after __WFE(),is to clear back the deep sleep bit.What is the effect to clear that bit?For your information. it seems to be very important on STM32WLE4CB because it fixed a mcu deadlock/crash issue i had recently.  I had a __NOP() following the __WFE() instead of the deepsleep bit clearing.Any information you got regarding this will be very helpful to understand.Best Regards  

Hi, I ran into a bug a while back where some ADC reads I had set up weren't working. In the course of debugging I found that the ADCs only worked after I changed the order in which some automatically generated startup functions were called in order to initialize the DMA controller before the ADCs. However, whenever I make changes to my .ioc and generate code it regenerates these startup functions in the wrong order. Why is this happening and how do I fix it?This is the incorrect order they are generated in:This is the order I have to change it to for the ADCs to work: 

Hi,Under TouchGFX designer application there is an advertisement touting "STM32U599 fully supported" with an image of the kit with the rounded display. I got the kit from ST (STM32U5A9J-DK / DK32U5A9J$AT1) with the STM32U5A9, with the same round display.Contrary to some other "board demos", this demo only works with the simulator. Maybe that's the reason why it's only present in the first tab named "demos", and not within the second tab "board specific demo".In the build section of the demo named "TouchGFX demo 6", which is exactly the same application running on the kit, there are no instructions to build and upload the demo to the target.How to solve this? Any hint?

Hi,We were looking at the LIS3MDL sensor. Apparently it is a magnetoresistive sensor. When we examined other magnetoresistive sensors in the market we have seen that they need set/reset circuits in order to compensate for the disturbances in the magnetic domains of magnetoresistive sensors. However, in the datasheet of LIS3MDL we couldn't see anything about it. Does LIS3MDL require an external set/reset circuit or is it already in the chip?

I am using STM32F103C8 MCU and Trying to communicate with Quectel EC200U-CN 4G module and i am not getting data through UART2 Receive pin. Please go through my code and suggest mevoid USART2_IRQHandler(void){ if ((USART2->SR & USART_SR_RXNE) != RESET){ GSM_buf[GSM_indx] = USART2->DR; GSM_indx++; while(!(USART2->SR & USART_SR_TC)); } if(GSM_indx >= (BUF_SIZE-1)) GSM_indx = 0; }

In RM0456 section 73.4.3 OTG_HS core (p.3279) I found the following statement:"The OTG_HS receives the 60 MHz clock from the reset and clock controller (RCC). This is typically generated in the PLL associated with the HS PHY and enabled in the RCC. This clock is used for driving the 60 MHz domain at high-speed (480 Mbit/s) and must be enabled prior to configuring the OTG core."I try to configure STM32U5A9 MCU with CubeMX, but I find no option to configure USB 60MHz clock.The only available clock setting called "OTG HS Clock" cannot be set to a value larger 32HMz and probably needs to match setting under "Pinout & Configuration" where this time it is called "Ref Clock selection" - see screenshots below.Where do I set 60MHz clock as described in RM0456? Instead, CubeMX offers 16/19.2/20/24/26/32MHz clock selection. In RM0456 I found no 16/19.2/20/24/26/32MHz clock values mentioned.Please advise. I am a bit confused.

I am trying to follow the "Getting started with X-CUBE-AI Expansion Package for Artificial Intelligence (AI)" document (User Manual UM2526), but I cannot validate the model on target.  Note that I'm using the STM32F746-DISCO instead of the recommended NUCLEO-F746ZG, but that's a minor difference.I can sucessfully validate the model on desktop (using random numbers and real data), but get an error when trying to validate on target using the "automatic compilation and download" option.CubeMX reports "Automatic build and run failed".Consulting the STM32CubeMX.log file I see the following error:2023-09-19 11:57:49,034 [ERROR] STM32CubeIDEBuilder:207 - !MESSAGE The project description file (.project) for 'mxAI1803873821400' is missing.

Hi there,We use a STM32F723 controller and want to connect two external RAM devices.Now we have to select a RAM that fits to the FMC. What we can't find in the reference manual RM0431 is, if SDRAM-DDR functionality is provided or only SDRAM without DDR.Does anyone have experience with the FMC connecting SDRAM and can tell us which SDRAM (DDR or no DDR) we can use?Best regards,Corsin

Hi All,I am new on STM32 and want to use printf on UART.I could run the printf on uart in the example folder.But couldnt find how does it work, actually couldnt find any comment in it about enabling printf on uart.I am useing STM32CubeMx and want to enable printf on its projects.I have tried some suggestion like adding following function that didnt work:void __io_putchar(uint8_t ch) { /** * \brief __io_putchar - A routine to transmit a single character out the serial port * \return void * \param[in] ch - uint8_t the character to transmit * \author andreichichak * \date Oct 16, 2015 * \details This routine assumes that we will be using UART2. A timeout value of 1ms (4th parameter) * gives a retry if the transmit buffer is full when back to back characters are transmitted, * avoiding dropping characters. */ HAL_UART_Transmit(&huart2, &ch, 1, 1);}Could someone help me on this issue? I am using NUCLEO-L011K4 board.Mostafa

Hi,Appreciate any help on how to enable u-boot splash screen during boot. I am using STM32MP157F-DK2.Thank you.   

The configuration I made for the ADC via STM32CUBEIDE to NucleoG032k8 is as follows. There are 3 channels. These are as follows;rank1:PA0(2V VOLT)rank2:Channel temperature sensorrank3:Channel Vrefint What is the reason why the raw value of 2 volts fluctuates so much?    

Hello everyone!I'm trying to debug a project based on the following video:https://www.youtube.com/watch?v=PXfCyE-LnR4As one of the steps, after adding the following text:#define CCRValue_BufferSize 37ALIGN_32BYTES (uint32_t DiscontinuousSineCCRValue_Buffer[CCRValue_BufferSize]) ={14999, 17603, 20128, 22498, 24640, 26488, 27988, 29093, 29770,29998, 29770, 29093, 27988, 26488, 24640, 22498, 20128, 17603,14999, 12394, 9869, 7499, 5357, 3509, 2009, 904, 227, 1, 227,904, 2009, 3509, 5357, 7499, 9869, 12394, 14999};I get the error:error: function 'ALIGN_32BYTES' is initialized like a variableI would like to know how to solve the problem.Thanks!

I would like to use the mbedTLS version 2.28.2.v2 on the secure boot for stm32h743ii controller. I have downloaded SBSFU v2.6.2 and Built the secure boot binary on top of the example project from H753 2_images_OSC folder. Secure boot is running the target hardware. But the .sfb file is not upgradable with the secure boot and it throws the FW authentication error.I suspect that the .sfb file created by windows executable exe is not using the integrated mbedTLS version 2.28.2.v2 somehow. Please suggest the next step.Regards,Rakkumuthu R

Hello,I'm working on a project where I'm using the ST25R3918 with RFAL libraries. Initially, I read the IC identity register and performed a right shift. Why did I perform this right shift?I modified the read register function, added a right shift, and successfully read the correct registers. However, my code is now not functioning correctly.What steps should I take to resolve this issue?This version maintains the same information while improving the clarity and correctness of the sentences.

Hello community,I am working on a project that involves the use of both CM7+CM4 cores from an stm32h7, to communicate both i need to use openamp. I have successfully made an standalone project that only have the openamp working, but when i port it to my actual project, it does not work/coexist with the touchgfxapp, i have found there an strange behaivour when i do initialize the MX_TouchGFX_Init before the MX_OPENAMP_Init, if i do the initialization that way, it would be "stuck" forever in the function: OPENAMP_Wait_EndPointready(&rp_endpoint);If i do initialize first the OpenAMP it works fine, until i need to communicate, being able only to send one message and receive one answer and stuck forever in the "OPENAMP_check_for_message();" function.I am going to put this functions (the initialization and also the message check) in freertos task because i have the suspect that this is due to "task/functions" priorities, and until now i have been working them outside the freert

Hello,I want to use ST's default OpenBootloader that the virgin chips have on board.The pheripheric I wanted to use is the UART1, and on the AN2606 Application note I saw that the pins I need to use are  PA9/PA10, or to be more precise PA11/PA12 since I'm using the UFQFN20  version. In fact, in the application note is written that: "On WLCSP12, SO8N, TSSOP20, and UFQFN20 packages USART1 PA9/PA10 IOs areremapped on PA11/PA12."However these are not the usual pins that I typically use for UART on STM32C011. My firmware also uses UART1 to communicate with an external microcontroller and in that case the pins that the datasheet states I can use are:USART1_TX: PA0,PC14,PB6;USART1_RX: PA8, PC14,PB6, PB7;Why are the pins used in your bootloader not the same as the ones that should in teory be used for USART1? How can I use the same pins for bootloader and user firmware?I don't want to customize the bootloader as I want to skip the flash programming in production.Thank you in advance.

Hello, am using RFID card reader ST25R95 using its stack. I want to reduce the fixed wake up time from 300ms to 100ms. #define RFAL_ST25R95_IDLE_DEFAULT_WUPERIOD 0x24U /*!< Fixed WU Period to reach ~300ms timeout with Max Sleep = 0 */Is there any method how i can reduce it, this delay is affecting my product as the user has to hold the card until it is detected. I have also set the RFAL WUM Period period; /*!< Wake-Up Timer period ; how often measurement(s) is performed */    ==>100msin struct RFAL Wake Up Config.But it is of no use..Is there any method how I can resolve it.
