 Hello Experts,Reviving this topic as the referenced video and suggested solution zip file are not available.https://community.st.com/t5/stm32cubemonitor-mcus/can-a-variable-be-modified-by-using-it-s-name-instead-of-it-s/td-p/87737 BTW I would expect such an ubiquitous feature to be already included in CubeMonitor. Perhaps my oversight but I could not find such a feature. I have a program with hundreds of variables I need to control from CubeMonitor, babysitting their addresses or spending ages updating them after every compilation is not practical.Thank You,-Alon. 

Hi,  I am not able to download the STM32CubeProg. Somehow the download just not start from https://www.st.com/en/development-tools/stm32cubeprog.html?ecmp=tt15529_us_social_may2020#overview Here in the image below you can see that it tries to do something but there doesn't appear any download in my internet browser. Yesterday I was perfectly able to download CubeIDE en CubeMX Is there anyone who can help me?

Hi,I’m working on an STM32F767 custom bootloader with two application slots:Main Application Slot → starts at 0x08040000Backup (Factory) Slot → starts at 0x08100000I have written a bootloader that checks both slots and jumps to the valid application: SCB->VTOR = app_base; // Set vector table offset __set_MSP(*(uint32_t*)app_base); // Set initial stack pointer void (*app_reset_handler)(void) = (void*)(*(uint32_t*)(app_base + 4)); app_reset_handler(); // Jump to reset handler ProblemI tested two scenarios: Using app_main.ld (FLASH origin = 0x08040000

Hello Support Team,for testing purposes i am using the H533NucleoBoard. I can load my firmware into the MCU and the firmware is running as expected.

Hello everyone,  I'm using STLINK-V3MINIE as my programmer. The VCP is functional when I received it. But as soon as I upgrade its firmware to V3J16M8 STM32 Debug+VCP, the VCP is unusable. The VCP device enumerated on Windows 11 PC is openable but doesn't give out any digital waveforms on RXD and TXD pins, also no message is displayed when I give a valid UART TTL signal to RXD pin. Currently its firmware is running on V3J16M9 flashed with ST-LINKUPGRADE software on Windows 11. VCP is still not working. I can't remember its factory firmware version. How to solve this problem? Ideally its VCP should work as many USB-to-TTL.

I have written a custom bootloader that is running on a Nucleo-L433RC-P board. The application uses USB CDC to call the bootloader and the bootloader uses USB DFU to download the application. I wanted to use USB to call the custom bootloader, rather than having to use a physical switch on the BOOT0 pin to call the internal bootloaderI can successfully download a simple application which just flashes an LED using the USB DFU bootloader.However, when I download my actual project, it appears to download successfully but does not run.My actual project is more complicated and uses the following peripherals:RTCSPI2 and DAC1 (using DMA)SPI1TIM6TIM7I2C1I2C2USBShutdown and standby using WKUP and RTC wake sources I used the following guide to write the custom bootloader and simple application...

Our STM32H745XIH microcontroller enters an infinite loop after updating the software with “Release” compilation flags (optimization enabled). This only happens with a specific build, and changing a single piece of code that is definitely not related to any hardware component can solve the problem (e.g., adding a single line such as int a = 45;). We believe the problem may be related to the watchdog reset, because when connected to the microcontroller via a debugger, it resets and starts working normally without any problems, the logic of our application works, and the device is fully functional. We thought the problem might be caused by the clock initializing too quickly, so we added a startup delay using: static void __attribute__ ((optimize("-O0"))) StartupDelay(void) { for(uint32_t i = 0x27614U; i > 0U; i--); } This seemed to solve the problem. However, after changing another part of the code, the problem start

I'm attempting to use a custom LCD daughter board designed to plug onto the STM32U5G9J-DK1 in place of the round display that comes with the DK1. The schematics for the DK1 have a note in read indicating that the DSI_CK_N and DSI_CK_P pins are reversed and that they should be swapped in software, and indeed the pin assignments on the schematics seem to agree with that note. The schematics for the round display board show those pins to be correct, i.e. not reversed. I have working example code for the round display, but nowhere in that code do I see that the DSI clock pins are reversed.There's a HAL function for doing this: HAL_DSI_SetLanePInsConfiguration(), and the DSI register that does the swapping is WPCR[0]. Nowhere in the working example project do I find any call to the function or any write to that register, so I'm confused as to how it could be working. Is the schematic not correct? Is there some other means of swapping the pins? Needless to say, my custom board is n

Hey all,For reference I am enabling the https server using NetxDuo Stack for firmware update in my device.Initially we were using Internal Flash but now we are interested in External Flash particularly SDRAM. I was able to boot the application code from SDRAM, however i am facing a problem, whenever i call a rest API like GET request a hardfault occurs where the stack traces shows it is originated over _nx_crypto_sha256_update() function in the nx_crypto_sha2.c file over the use the memcpy(). The strange thing is everything works with no hardfault when application work in Internal Flash.Furthermore, I am able to run RTOS on SDRAM and i can ping my IP on ethernet as well.Kindly someone help me out for this, i will be grateful.Also if i should report this behavior somewhere else?Thanks

STM32H562, STM32Cube FW_H5 V1.5.0, X-CUBE-FREERTOS.1.2.0If i want a FreeRTOS queue of size 32 and item size 12 bytes i will write 32 i Queue Size and 12 in Item Size in CubeMX. Previously it would generate init code:osMessageQueueId_t setpoint_sendHandle; uint8_t setpoint_send_buffer[ 32 * 12 ]; osStaticMessageQDef_t setpoint_sendControlBlock; const osMessageQueueAttr_t setpoint_send_attributes = { .name = "setpoint_send", .cb_mem = &setpoint_sendControlBlock, .cb_size = sizeof(setpoint_sendControlBlock), .mq_mem = &setpoint_send_buffer, .mq_size = sizeof(setpoint_send_buffer) }; setpoint_sendHandle = osMessageQueueNew (32, 12, &setpoint_send_attributes);With STM32Cube FW_H5 V1.5.0, X-CUBE-FREERTOS.1.2.0 i get:osMessageQueueId_t setpoint_sendHandle; uint8_t setpoint_send_buffer[ 32 * sizeof(12)]; osStaticMessageQDef_t setpoint_sendControlBlock;

I’m working on an STM32MP135 (STM32MP13‑DISCO) using Yocto/OpenSTLinux 5.15 and trying to get SPI5 working via the spidev interface. My device tree configures SPI5 pins and enables spidev@0 at 500 kHz (see DTS fragment below). /dev/spidev0.0 appears on boot.For testing, I have physically connected MOSI to MISO for loopback, and CS (PH11) is connected to the peripheral and can be pulled low. I run the loopback command:./spidev_test -D /dev/spidev0.0 -s 500000 -vHowever, the transfer fails with:spi mode: 0x0 bits per word: 8 max speed: 500000 Hz (500 KHz) [ 494.413391] spidev spi0.0: SPI transfer timed out [ 494.416807] spi_master spi0: failed to transfer one message from queue can't send spi message: Connection timed

Hi!I'm having an issue with the CDC class for USB on my STM32L476 board. I am using the Receive function in usbd_cdc_if.c file to track incoming Modbus traffic from USB. I am noticing that when I write multiple registers (function code 0x10) to the slave using Modbus Poll Software, the incoming buffer always has the last byte as 00. Here are some images to help explain:The following image is a Communication Log from Modbus Poll Software that shows the Modbus Frame being sent:Notice the highlighted portions, which are the CRC Lo and CRC Hi bytes. I also confirm with a USB sniffer program that these exact frames are be

I'm sure it's something silly and I can't believe I'm the only person who has seen this message but searching this site doesn't yield any clues. Can someone point me to what I am setting up wrong, presumably in the Debug Configuration menu ?

Hi everyone!I am currently testing the reading of a tag with an ST25TV02K chip using two different readers. Both readers are based on the same NFC chip and use the same antenna coil, but they differ in the matching network between the NFC chip and the antenna.In theory, the first reader should be better matched to the NFC chip, while the second reader should be less well matched (and therefore expected to deliver less power). I have verified the reader matching using a VNA. However, I am observing an issue: at the same tag-to-reader distance and with the same power settings, tag read/write operations with the ST25TV02K sometimes fail when using the better-matched reader. This makes me wonder whether the better-matched reader might actually be delivering too much power to the tag, such that the VAC0–VAC1 voltage exceeds the maximum limit, preventing the ST25TV02K from responding correctly. Conversely, the less well-matched

Hello,I drived lcd by using partial frame buffer. Now, I am trying to update it with double buffer strategy. The LCD has TE pin that helps checking Vsync.I could not find a clear example for double buffering method. I don't need FMC since internal ram is enough for driving.Do you have any example or steps that I need to follow for those specs:Touchgfx with double buffer + FreeRTOS (CMSIS V2) + SPI LCD (With TE pin)  Touchgfx Version : 4.25.0CubeIde Version : 1.17.0MCU : H7 seriesBest regards,Faruk

I am having a "how did this ever work" moment. Maybe I found a (horrible) bug, or maybe I'm overlooking something.In tickless idle mode FreeRTOS uses the COUNTFLAG in the SysTick SYST_CSR to determine if WFI exited due to the systick, and then calculates how many RTOS ticks have elapsed: configPRE_SLEEP_PROCESSING( xModifiableIdleTime ); if( xModifiableIdleTime > 0 ) { __asm volatile( "dsb" ::: "memory" ); __asm volatile( "wfi" ); __asm volatile( "isb" ); } configPOST_SLEEP_PROCESSING( xExpectedIdleTime ); /* Re-enable interrupts to allow the interrupt that brought the MCU out of sleep mode to execute immediately. see comments above __disable_interrupt() call above. */ __asm volatile( "cpsie i" ::: "memory" ); __asm volatile( "dsb" ); __asm volatile( "isb" ); /* Disable interrupts again because the clock is about to be stopped and interrupts that execute while

Hello,Is it possible to show indent guides (vertical dotted lines) (for example, see Figure 1 below from the Visual Studio 2022) of the STM32CubeIDE code editor?    Figure 1. 

 Hello,I am working with the STM32N6570-DK board and running the STM32N6-GettingStarted-ObjectDetection example. When I debug the program in CubeIDE (The MCU runs in Dev mode), I encounter the following issue:In the main loop, when the function LL_ATON_RT_RunEpochBlock is called, the debugger reports:Target is not responding, retrying...At this point, pressing the NRST button on the board does not reset the MCU. The only way to recover is to power cycle the board.Any suggestions would be greatly appreciated.Thanks in advance! 

Hi all,I would like to create a custom slider with 2 indicators of the lock when they lock vs. unlock and 2 background image text with Lock and Unlock texts.I similar like a toggle button, but it actions like a slider; once it goes to the left is locked and right is unlocked.Is there anyway I can achieve this? Thank you.
