Hi,I have problem with debugging execution from internal SRAM. I use Cube IDE and STM32H750 Disco board. There was no problem when I debug from flash. But when my binary size exceeded the flash capacity(128KB), I had to use external memory for the program code. I am copying code to internal sram and execution starts from address 0x24000000. I am able to run and suspend the application using debugger. Then I can resume it. It works. So far so good.But when I set a breakpoint, it stops at there but then can't continue somehow. It gets stuck there. I can't resume, step out, step in etc. from there. And console writes this: handle_vCont_t, Thread already stoppedI see PC and SP. They seem ok.Am I missing something in debug configuration?I appreciate your helps

Hi.I was going to buy STM32MP157C-DK2 but its status NRND(Not Recommended for New Design). So I think to buy STM32MP157F-DK2. Are they different point is only a clock(650 or 800) of A7 core? What's the difference?Thank you.Best regards.

Here the details.I'm writing my own firmware to read the NFC type A and B on a custom board based strictly on NUCLEO-NFC06A1. I found it difficult to work with the STM32L476RG-Nucleo_PollingTagDetect example. To debug and "reverse engineering" the code is too much and it would take too long.A the moment I am able to set the registers to perform a request. I was able to check on the oscilloscope the signal generated and it works according to what I expected. However since I don't read any data I don't know if I set all the registers correctly.My struggle come from this point. Now I'm trying to print out all the registers of the ST example to see how they change and compare it to the ST25R3916 datasheet in different points.Can you help me out by pointing how to go about it or where to look?I saw there is ST25R3916-DISCO that comes with a SOFTWARE GUI which allows you to debug more easily. Would this evaluation board be helpful?Thank you in advance

How can I get an event, if the smartphone have read out or written data into the card emulation memory.

I want to know what "st-image-xxxxx" parameter mean.Especially, I want to know what name of xxxxx (for example "weston") means.​Is the name of xxxxx related to the name of some config file?For example, if I changed the name of xxxxx to any name from weston, Are output files by bitabake influenced?​​Best Regards,H.

I am trying to update STM32CubeL4 package from v 1.14.0 to 1.16.0. Refreshing packages in manager does not show new versions. I downloaded zip from STM site and tried to add it using "From local" button. The integrity check and unpacking went without problem, however the package is still not shown in a list. If I try to update from a file again it says "this version already available from Repository".

Hello,I am using an STM32F4.I need my mcu to go to sleep (preferably a stop) and i want it to be able to wake up because of a pin or a set timer.My problem is that i am not able to know how much time has elapsed when i wake up because of a pin.Does anyone have an idea of how i can do that ?

We would like to share data between the A7-core and the M4-core on an STM32MP1 device. Those cores both have access to the SRAM1,2,3,4 . The M4-core is connected directly via the AHB interconnect, the A7-core is connected via the AXI-based NIC-400 interconnect which has access to the AHB. Since both interconnects have a bit-width of 32 bits or more, I am wondering if writing or reading to/from a 32 bit address will always be atomic, at least for aligned accesses. So for example, if the A7 is constantly writing a uint32 into a commonly known memory address in SRAM1 and the M4 is constantly reading this address, is it guaranteed that the M4 will never read a partially updated value?Thanks in advance

Hello,I am using IHM02A1 expansion board (on top of L073RZ), which has two L6470 connected in a daisy chain configuration. I cannot receive any data from the devices. What do you think the reason can be ?Below is the bus status of a reset and get param for register ACC (0x5) since its default value is not 0: 

Hello,I dont know what is the problem, but when USB is configured in CDC mode in CUBEMX (maybe other modes also can generate the same problem, havent tested yet.) and the code is generated with CUBEMX, touchgfx code genereation will result in file omition from KEIL. There is no matter with STM32CUBEIDE since folders and files are not touched.One suggestion: Touchgfx designer consider some standard place for user code like stm32cubemx so in the regeneration of code, user code remain untouched. The IOC file to ease the problem regeneration is attached.

Hello, why are the keywords class, public, virtual not in bold font?Where to change this feature?

Hello, can the pin configuration shown below possible?We need one bidirectional UART and a CAN along with a UART TX for debugging. Questions are:It says "Pin pair PA11/12 can be remapped in place of pin pair PA9/10 using the SYSCFG_CFGR1 register" So I would only need PA10 to be remapped to PA12 for CAN TX. Is this possible?Can USART be initialized with only TX pin?Would there be any issue with using CAN RX with BOOT0 pin?Thanks, Prithvi

Hi, I am trying out the cubeide coming from IAR. I am currently having a problem that some interrupt is occuring which goes to the default handler. Since all unmapped interrupt functions go to the same handler apparently CubeIDE shows an incorrect interrupt as entry point. So I am trying to figure out which interrupt is really occurring. I thought I would go to the register view and look op the nvic registers but it turns out that this register view is only showing some core registers and not the peripheral registers (stm32f7). Can I find them somewhere else ? Other suggestions ? Worst case, is there an (easy) way to add them myself ?

I have problem with bootloader on STM32G031. I am using pins PB6 and PB7 according to manual (AN2606), but no response at address 0x51 (I hope Slave 7-bit address: 0b1010001x means 0x51).I am getting into bootloader by rebooting and remapping SYSCFG_MEMRM to 0x1 in early state. After that I am able to use serial bootloader on pins PA9,PA10 (USART1), but not I2C.In my user application I2C slave mode is working properly on pins PB6, PB7.In final application I will have only I2C connection from master system and I will need to reprogramm slave firmware. I was expecting I will use system bootloader.Is anybody using I2C bootloader on STM32G03x succesfully?Please give me any advice, how to debug this problem and/or what else I can try.

I succesfully use I2c slave mode on address 0x52 in my application.I can get into bootloader via software by rebooting and in early state remapping SYSCFG_MEMRM = 0x1.But in bootloader, I2C on pins PB6 and PB7 is not responding to address 0x51 - (stm32flash posts "responding Failed to send command"), as for other random - not used - I2C addresses . I can use succesfully serial bootloader (I am using patched stm32flash) on pins PA9,PA10 (USART1), so I suppose I am getting bootloader mode correctly. PA3 pin od USART2 is high, so I hope I am not affected with problem "stuck in USART2 detection" described in AN2606.If I would try stm32flash on I2C in running state (not bootloader) on address 0x52, it will respond with Unexpected reply from device on command 0x01 (which is normal, because it is my application running, not bootloader).I have tried also to use the same address as bootloader (0x51) in my application, but also no luck.Please give me any advice what I should try more.Finally I w

Hi,I m working on STM32F769-DISCO board. I m using on STM32CubeIDE(vers. 1.5.0) and internally CubeMx(vers. 6.1.0). When I create new project, CubeMX interface is opening as you see on attached screen shot.I can not activate USB_OTG_FS as "Device Mode". However some of all peripherals are inactivated. How can I fix appearances of these modules? Best Regards

Hi.It's ready to use MP1 peripheral(USB, Ethernet, SD card) right away if I download to OpenSTLinux image to MP1-DK board after downloaded on ST website? or Do I need to make device driver for peripheral?Are there guiding, or tutorial for making application about using USB, Ethernet or SD card on OpenSTLinux?Thank you.Best regards.

In the states RFAL_LM_STATE_POWER_OFF or in RFAL_LM_STATE_IDLE ( function rfalRunListenModeWorker File rfal_rfst25r3916 ) the flags ST25R3916_REG_OP_CONTROL_en_fd_auto_efd are reset during detetcting a smartphone. These bits are set only during initalisation. but why are they reset during working? ? ?A workaround works better but not sufficient, sometimes a smartphone is detected. The workaround sets the ST25R3916_REG_OP_CONTROL_en_fd_auto_efd bits in both states (see code below).The hardware is the discovery antenna board with st2533916 and via spi connected to our µc STm32L151.The hardware antenna works with discovery mainboard fine.Additional we implement in depency of the field on , to switch from power off to idle and reverse. (seee below)On the saleae.com you can download a software, to analyse the logic spi data attached.Ther are two records wih detecting a smartphone. The first tooks a long time to get the smartphone. the sceond ist ok.   switch( gRFAL.Lm.st

Hello All, Working with an STM32F4 processor and having issues with feeding the independent watchdog. Code is CubeMX generated. FreeRTOS v10.2.1 and CMSIS-RTOS V1.02. Watchdog resets if not fed every 512ms. Watchdog is fed in its own task and the priority is set to osPriorityRealTime. All the other tasks are osPriorityNormal. configTICK_RATE_HZ is set to a 1000 and configUSE_PREEMPTION is set to 1. The SYS timebase source was also changed from Systick to TIM7 as per a warning popup on CubeMX. So the issue I'm facing is that the watchdog resets the processor consistently every half a second or so even though I'm feeding it in the RealTime Task. I can confirm that it is the independent watchdog resetting the processor from the RCC->CSR register. I can also confirm that it is not an issue with the feeding process, as if I create an infinite loop right before the osKernalStart() and feed the dog in there the microcontroller runs perfectly fine and if I don't feed the dog in th
