Does the system memory bootloader for the STM32L4P5xx consider RAM3 as valid SRAM for the stack pointer?After programming bank 2, and then setting BFB2, The device will not boot into bank 2.  The linker has the top of the stack at RAM3.  The value written to both 0x8000000 (bank 1) and 0x8040000 (bank 2) is 0x20050000.  I want to make sure this is correct.  By the way, this is the 512K part STM32L4P5xE.  The other relevant options bytes are set as follows: nBOOT1=1, nSWBOOT0=0, nBOOT0=1 (BOOT0=0).  When I clear BFB2 I can boot.  I have compared the flash memory from 0x08000000-Length with 0x8040000-Length, and they both match.

I am trying to write to the flash memory of the STM32L4S5QIIX microcontroller on the EVAL-ADIN1110EBZ development board. I have also tried similar code on an STM32L4S5VITX microcontroller on a custom circuit board.Short example code:uint32_t flash_memory_address = 0x08100000; uint64_t flash_write_data = 0x12345678; uint8_t flash_read_data[4]= {0}; HAL_FLASH_Unlock(); FLASH_PageErase(0, FLASH_BANK_2); HAL_FLASH_Lock(); HAL_FLASH_Unlock(); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_ALL_ERRORS); HAL_StatusTypeDef status = HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, flash_memory_address, flash_write_data); HAL_FLASH_Lock(); The full code and project files can be found at: https://github.com/landas/stm32l4s5-flash-memory/blob/e8304c3d17e27ee9f27f8a8243ceb7f73ba077bf/Core/Src/main.c#L135FLASH_PageErase(0, FLASH_BANK_2) operation was completed successfully. This was verified by using STM32CubeProgrammer to write to the flash memory and confirm the changes in the specified memory are

Hi, was wondering if anyone could suggest what the problem could be with trying to build the example USB-C PD Source application per this tutorial :https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_SourceI've checked that I have worked through all the steps as instructed but build is failing with error :/USBPD/Target/usbpd_devices_conf.h:83:58: error: 'valueNotSetted' undeclared (first use in this function)83 | NVIC_SetPriority(valueNotSetted,2); \Looks like I have a missing or incomplete header file. Can anyone help?

I am using NUCLEO_H723ZG in which I am using 12-bit resolution ADC. Below is the clock used for ADC:Moreover, I have used DIV2 clock prescaler. So my BOOST bits in ADC_CR register should be 11 as it is mentioned in the reference manual.I checked those BOOST bits while debugging and they are set 10 instead of 11.So I assumed the clock frequency to be 50 MHz and checked all the condition. With that all condition the BOOST bits changes accordingly.Although 64 MHz is shown there but the clock frequency used is 50 MHz?

I have an STM32L011 on a board I am developing.I can enter the bootloader no problem, as per AN2606/AN3155.  I am using USART2, 57600 baud.I can program FLASH/erase FLASH/read FLASH - all works as expected.I note that the bootloader reserves 2048bytes of SRAM, I assume it's the addresses 0x2000_0000 .. 0x2000_07FF.When I try to use the memory read command to read from anywhere in SRAM (whether the bootloader reserved area or any other address) I get a NACK just after the address+xor-check-byte.I believe the protocol is correctly implemented because the same thing works reading from FLASH addresses (e.g. 0x0800_0000).Is there a known issue here (I have seen other posts on this forum with similar problems on other STM32 parts - but these are either unresolved or they are trying to read from the reserved SRAM which is expected to be NACK'd). 

NUCLEO-WB55RG communicating via SPI1 to an ADXL362 eval boardI set up the project (attched below) using CubeIDE, generated the code & placed my own callbacks for the SPI in main.When I look at the value for the Z direction I should be getting a value that indicates roughly 1g but all I get is 0. The same for all the other axis, no change in any value no matter how I orient the sensor.To check that the acceleromter was working I hooked it up to an Arduino using a 3rd party library especially for the ADXL362. That all worked as expected, so I know the accelerometer is working.When I go through the code with the debugger it doesn't hang anywhere so I'm guessing my callbacks are working, its just I dont get any data back, all values remain at 0Anyone see anything obvious that I'm doing wrong?

 I'm using an STM32H7 microcontroller to interface with an OV2640 camera. I'm utilizing the 8-bit DCMI interface to capture data from the camera and transfer it to a DMA FIFO buffer. My camera configuration includes generating an 8MHz MCO signal for the MCLK input on the OV2640. I'm processing the data with a Digital Signal Processor to obtain RGB565 format at a resolution of 120x160 pixels. Currently, my HSYNC is set to HIGH, VSYNC to LOW, and I'm using a pixel clock with a rising edge. The problem I am having is I get no valid bytes from the DMA FIFO buffer. I get the value of 0x00. Below is my main.c with the functions running the program, the values I write to the register also work. Please help.

Hi,i am using NUCLEO-WBA55 with the BLE_p2pServer example from firmware package.Here for example in file app_ble.c is a define statement#define ADV_TIMEOUT_MS (60 * 1000)and this ends the advertising after 60 seconds.However, I would like to start and stop the advertising individually with a command, for example.Can someone explain to me how I can do this?

I am working with a dual core STM32H755 and attempting to create a shared memory location for the two cores to access. I am attempting to do this by modifying the linker script.  I have added the following lines to the M7 core linker script, in the SECTIONS block:/* Shared Memory section for inter core comms */ .sharedRAMsection 0x30040000 : { .= ALIGN(4); KEEP(*(.sharedRAMsection)) . = ALIGN(4); } > RAM_D2 Then in one of my .c files, I have declared the following global variable:RegisterMap_t __attribute__((section(".sharedRAMsection"))) g_RegisterMap; However, when I debug I can see the address of this variable has been assigned to memory location 0x24000064, as seen in the watch window: I am using visual studio and visual GDB, and I am debugging with 2 separate VS instances for the two cores. Is there something else that I need to do in order to get this variable into the correct memory location? Thanks 

I am currently making an artificial horizon for a project in TouchGFX, but I just noticed that when I tried to use the svg of the Pitch_Angle_Indicator that has numbers I get a compile error. Are there any plans to implement the usage of numbers in svg images? BSNeyus 

Hello, I am asking for help from the community. My application is completely written, but I can't set read protection. I tried to do all the steps in this guide, but it led to bricking one of my boards. The second board is still in product state = 17? but I can't install the obk file or remove protection, returning it to the ED state. Cube programmer did not give me the choice "Change the PRODUCT_STATE option to 17, then press [Apply]. A window appears asking if the default DA-Config should be applied, press [NO]." it just set the state to 17 without asking.I did not find any sensible information on the network on how to set or remove protection. Maybe it is possible to do this directly from the application? in state 17 I can flash h503, but I can't switch to debugging.I really ask for help, my project is completely ready, but it needs to be protected.

Hi. I am programming a board with STM32G0, which is battery powered. All processor pins are used. Overall, the device works without any problems. In normal operation mode, only STM draws about 3.5mA. However, I wanted to put the device to sleep and:1. In Shutdown mode, STM draws 40nA (according to the documentation), and the entire device 720uA, which is satisfactory for me, but I want to be able to wake it up from a dozen or so GPIO pins, so I tried to start Stop mode and:2. In Stop mode, STM draws 600nA (more than the documentation indicates, but still quite good). I have the ENABLE pins of the additional LDO and charge pump connected to the PB9 pin through 100R resistors, which are on the PCB and power other systems. There is also a 4k7 pull-down on the ENA pins. During normal operation, PB9 is in a high state, and before sleep it is set to a low state to turn these systems off. And here comes the problem: when I leave PB9 in the high state before switching to Stop mode, the cu

I have connected the STEVAL-25R200SA via micro-USB to the computer however the device is not identified.  Is there any virtual com port driver needed for this and if so can someone provide what it is that I am missing.  

I am trying to debug some functions to write to the memory mapped QSPI. When I go to debug it, I notice that before any functions even run the QPSI is in HAL_QSPI_STATE_ERROR, therefore I cannot test my code to see if is running because it is dependent on the State of the QSPI. My QSPI is a WinBond25Q128JVSQ. Is there a way to trouble shoot this?

I am looking for help solving a CDC-ACM problem with Azure Rtos ThreadX, and the USBX Middleware for STM32F4.My device is an STM32F427VGTx.I currently have a project that uses the USBX host library. I am connecting up to 4x CDC-ACM devices through an off-the-shelf USB Hub.I had problems connecting multiple devices through the hub, but I have solved that after following the solution to update the USBX core bsp from the stm32-mw-usbx repo. (STM32H7 and USB2514 Continued Problems) I can connect to all 4x CDC-ACM devices (data class instance and control class instance enumerate successfully on all devices).I can send commands to all devices using the control interface by sending a transfer request to the control endpoint.I can read from up to two CDC-ACM devices, but the third and fourth device will timeout after calling ux_host_class_cdc_acm_read. The function returns a transfer-request-timeout after failing to retrieve the ux_host_semaphore. The status of ux_host_semaphore_get is al

Hi, I'm using a fresh debian testing (12) and when i try to launch "SetupSTM32CubeMonitor-Power.jar", i get the error :Command line arguments: SEVERE: java.lang.ArrayIndexOutOfBoundsException: Index 70131 out of bounds for length 22674Debian is not in the supported operating system, but ubuntu should not be so far. I found on the forum, that the error occured on stm32cubemonitor on ubuntu recent version.Is there a patch/upgraded planned or anyway to make it run ?Could someone on ubuntu tell me if it work on it ? Thanks in advance,

If I find a bug in CubeIDE/CubeMX's code generation (like not turning on power to SDMMC), is there somewhere on my system that I can alter the boiler-plate code that is used to generate the project until the correction comes out in a future release?Thanks,Andrei (from The Great White North)

Hi, ST Community!We are developing a device based on the STM32MP257DAK3 processor.The firmware is built using Yocto (Scarthgap release) with Linux kernel 6.6 from ST and the meta layers meta-st-openstlinux and meta-st-stm32mp.The device includes a USBPD controller (MAX77958) that is managed by an external microcontroller. This setup is intended to allow USB charging independently of the main processor.Goal:We want to enable USB3DR in USB 2.0 peripheral mode (to use USB gadget / Ethernet over USB under Linux).In U-Boot and DFU mode, USB works fine→ The PC sees the device→ Data transfers are successful→ USB traffic is visible on the oscilloscope After Linux boots:→ The PC doesn’t detect the USB device→ USB lines are completely idle (both lines at 0V)→ usb1 interface appears in ifconfig→ No errors in dmesgDevice Tree config (from ST documentation):&usb3dr { status = "okay"; dwc3: usb@48300000 { maximum-speed = "high-speed"; role-switch-default-mode = "peripheral"; usb-ro

Hello everyone. I'm currently just learning and getting familiar with microcontrollers. For educational purposes, I would like to set up master-slave communication between two C8T6 boards. The master should send an array of values, which the slave receives and evaluates. If the array matches a predefined pattern, the slave sends a response—also an array of values. The master receives the array and, if it matches the expected pattern, changes the state of an LED. This process should repeat in a loop.When I connect the power, only the LED turns on and nothing else happens. If I reset the slave (using the button on the board), the communication starts working and the LED begins blinking. I can also get the communication to work by resetting the master, but I usually have to press the reset button several times before it connects properly. The slave always connects correctly after a reset.If someone could help me figure out what I'm doing wrong, I would really appreciate it. I've been stru

Hi, Recently I have mistakenly upgraded to FUS 2.0 and BLE stack 1.22.1 for my stm32wb5mmg chip. I was using FUS 1.2.0 and BLE stack 1.22.0.2 before and the system behaves perfectly fine with the firmware on hand. After upgrading it the device doesn't seem to be advertising and couldn't be detected by any other devices. I have notice that it is impossible to downgrade the FUS version is there a way to tackle the issue? If I wanted to erase the whole chip and copy the memory of a working chip, is that possible?
