I am trying to get application level RDP progression into my bootloader to kind of self protect my firmware once it has started. I have set level 1 and the firmware still runs and I can no longer read out flash or debug, so that's the positive side.But now I want to continue debugging the board, so I want to get back to level 0. I already found out that (for whatever reason) the only way to at least start a connection is now to use Hotplug and only release the reset of the board by hand once Hotplug is selected.But I can not read or write the option bytes or use the specific downgrade command. What I tried and didn't work via CLI: ./STM32_Programmer_CLI.exe -c port=swd mode=HOTPLUG -rduDisabling memory Read Protection... Error: Disabling memory Read Protection failed./STM32_Programmer_CLI.exe -c port=swd mode=HOTPLUG -ob rdp=0xAAUPLOADING OPTION BYTES DATA ...Bank : 0x00Address : 0x40022040Size : 36 Bytes▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ 0%Error: Up

I am looking into using the Open Bootloader to develop a FDCAN/CAN bootloader for the STM32G431RxTx MCU. Does anybody have an example for this? Or any pointers to good resources.The examples in CubeMX seem to be for an older version of Open bootloader then the one that can be found in https://github.com/STMicroelectronics/stm32-mw-openbl/tree/main and have not seen any for FDCAN/CAN at all.

 Hi everyone,I'm currently working on developing an audio player with a display interface on the STM32F469I-Discovery board. I've got both the audio and the display working on their own. However, when I try to use both at the same time, I get an FR_DISK_ERR on f_lseek in audioplayer.c at line 42.I thought I'd give you a quick overview of my setup:Audio Codec = CS43L22Display = Integrated LCDWhat I've Tried:Audio Playback: It works perfectly when the display is not in use.Display Interface: It functions correctly when audio playback is not active.Simultaneous Operation: I get an FR_DISK_ERR during f_lseek operation in the audio player code.Error Details:File: audioplayer.cLine: 42Function: f_lseek The code is provided in a zipped file in the appendix below. Thank you very much :D 

MCU use : STM32U073RBT6STM32CubeIDE use : 1.16.0 We are currently working on a project that require to read the ID Code of the MCU. The software work well when ran in debug mode, but return 0 when running without the debug mode running.The code that we use today to access to the ID Code is: uint32_t idcode = DBGMCU->IDCODE  We looked to the address base of DBGMCU and everything looks fine (0x40015800). When looking online we saw that there is a similar errata on the STM32F101x8/B, STM32F102x8/B and STM32F103x8/B (https://www.st.com/resource/en/errata_sheet/cd00190234-stm32f101x8-b-stm32f102x8-b-and-stm32f103x8-b-medium-density-device-limitations-stmicroelectronics.pdf -> Refer to section 2.2.2).

I have set up a project in STM32CubeMX. I have setup both I2S1 for Receiving and I2S2 for Transmiting with DMA. After the normal initalization i start receiving from the DMA:       if (HAL_I2S_Transmit_DMA(&hi2s2, (uint16_t*)&output_buffer, 1) != HAL_OK) { Error_Handler(); }       And the setup of the I2S are as following:       void MX_I2S1_Init(void) { hi2s1.Instance = SPI1; hi2s1.Init.Mode = I2S_MODE_MASTER_RX; hi2s1.Init.Standard = I2S_STANDARD_PHILIPS; hi2s1.Init.DataFormat = I2S_DATAFORMAT_32B; hi2s1.Init.MCLKOutput = I2S_MCLKOUTPUT_ENABLE; hi2s1.Init.AudioFreq = I2S_AUDIOFREQ_48K; hi2s1.Init.CPOL = I2S_CPOL_LOW; hi2s1.Init.FirstBit = I2S_FIRSTBIT_MSB; hi2s1.Init.WSInversion = I2S_WS_INVERSION_DISABLE; hi2s1.Init.Data24BitAlignment = I2S_DATA_24BIT_ALIGNMENT_LEFT; hi2s1.Init.MasterKeepIOState = I2S_MASTER_KEEP_IO_STATE_ENABLE; if (HAL_I2S_Init(&hi2s1) != HAL_OK) { Error_Handler(); } } void MX_I2S2_Init(void

Dear community,I'm currently working on a student project where we need to analyze the performance of the FMAC unit of the STM32G4. My idea is to implement an FIR filter and measure how many clock cycles the FMAC operation takes to filter a predefined set of test data. I also plan to measure the execution time. After that, I intend to compare the results by implementing the same FIR filter in software using the CMSIS library.I found AN4841 , which demonstrates performance measurement results of the CMSIS FIR filter on two different STM32 platforms.Since I've never done this kind of performance benchmarking before, my question is how are the number of cycles and duration measured? Should we use the SysTick timer or the DWT unit for time measurement?Thank you!

I can see from logging that my Presenter's #activate is called after the screen's #setupScreen. This seems wrong. The screen depends on the presenter. There should be an opportunity for the presenter to initialize itself before the screen uses it.Am I misunderstanding something?Thanks. 

Im trying to bootloader my firmware in my nucleo G431RB vía canbus with a StLink v3 set,  its posible?. In An2606 says there is no opción.Do i have to write the bootloader ? And with that i will be able to load vía StLink v3 set?

Hi, Iam a embedded systems engineer currently working on a NFC payment terminal using Android as it OS.We have selected the ST25R3916B chip as the NFC transceiver, given its hardware characteristics it would be perfectly suitable for our application.I know that there is no currently working example of its linux demo driver "STSW-ST25R013" on Android, and would like some directions on how I could implement this integration, Iam already familiar with the Android framework architecture, and have seen that the st21nfca and st95hf chips have been integrated into android in the past, but in both cases they dont use RFAL, and the above mentioned demo driver for the st25r3916b chip does use it. So, is there any nfc chip that has been integrated into Android that is similar enough to st25r3916b for me to use as a base for integration? Any help or information is appreciated, and if ST could directly give me any support I would be glad to share the code with the community once its has been fully

I have been trying to get the debug setup running in CubeIDE 1.16 according to : dm00629855 Getting started with projects based on dual-core STM32H7 microcontrollers in STM32CubeIDE - Application noteAnd I was able do see the debug break point holding in the main of M7. Then it ended no ware, so I did a retry of the launch group and then "I got No device found on target" from The ST-Link GDB link. Here I am stuck: Also tryed:Reset the ST-Link and the USB tree and the Port numbers of GDB - this did not help.Then also the Cube Programmer  not find the device but the ST-Link is there so what did the debug session do to the MCU to be undetectable ?!  So what could I have done wrong and what can I do to bootstrap ? please help

Hello.I have a question while using two examples(BLE_Audio_TMAP_Central, BLE_Audio_TMAP_Peripheral) provided in STM32Cube_FW_WBA_V1.4.0.This example provides voice communication via BLE.In this process, I want to transmit voice communication data via UART or SPI communication as well as BLE.However, the configuration for BLE communication is not disclosed in the shared function in the project. (tmap_.app.c, codec_mngr.h) void APP_NotifyTxAudioCplt(uint16_t AudioFrameSize)CODEC_ReceiveData(TMAPAPP_Context.cis_snk_handle[i], 1, &aSnkBuff[0] + AudioFrameSize/2 + i); void APP_NotifyRxAudioCplt(uint16_t AudioFrameSize)CODEC_SendData(TMAPAPP_Context.cis_src_handle[i], 1, &aSrcBuff[0] + AudioFrameSize/2 + i); I would like to ask if there is a way to disclose or guide the configuration of this part.

Hi,a bit of a basic question... for years I used PIC micros so I was very familiar with their manuals, register and bit naming etc.But being new to STM32 I found it difficult to figure out an easy way to find the naming of registers and bits inside register (without having to read tens of pages every time)? Both in the reference manual (RM0394) and also the related HAL function? So for example, what is a quick and simple way to find the register name and description for things like changing the polarity PWM CH1 CHN polarity as highlighted in the screenshot below (or any other register and register bit)? Thank you as always.   

Hi,I am relatively new to STM32 development and would greatly appreciate any assistance with the following issue.I am encountering the following compile-time error: C:/mvt1/TouchGFX/gui/src/settingsa_screen/SettingsAView.cpp:7:10: fatal error: ..\Drivers\STM32H7xx_HAL_Driver\Inc\Legacy\stm32_hal_legacy.h: No such file or directory 7 | #include <..\Drivers\STM32H7xx_HAL_Driver\Inc\Legacy\stm32_hal_legacy.h> | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. I have added the necessary path to my project settings, and the file stm32_hal_legacy.h is present in the specified folder. Despite this, the IDE is unable to locate the file. Could you please provide guidance on why this issue might be occurring?Thanks 

I want to be absolutely sure, so should T_NRST be connected to CPU reset. (In this case STM32H750.)

The hardware for my project is an Arduino Opta, which utilizes the STM32H747XI dual core processor. We are trying to implement a watchdog timer for our application because the OS occasionally crashes. The start and kick timer functionality works without a problem. However, we are having trouble stopping the timer. We need to stop the timer during over-the-air "OTA" updates because it is a long running process.If I am understanding the datasheet correctly, it appears that stopping the timer is only available in debug mode. Please confirm.If stopping the timer is not an option, how would you recommend we tackle this problem? Is it possible to do the OTA update on the second core while the timer is running along with the main application on the first? Thanks in advance for your help. I've spent a lot of time trying to solve this problem.Regards, Mark

Hello,Can anyone suggest whether or not I need to connect external capacitors to the VREF+ pin if I plan to use VREF only for the onboard DAC?Could this be a hardware problem?STM32G431CBT6. The problem is that on the oscillogram I see oscillations with an amplitude of approximately 490 mV on the VREF+ pin. This is when Scale 2 is set to 2.9 V. If I reduce to 2.5V, the swing will be almost 1V overall. Nothing but the 1:10 oscilloscope probe is connected to the VREF+ pin on the board.Below are the screenshots.

Hello,VCAP1 and VCAP2 are external capacitors for the core's voltage regulator.The data sheet for the STM32F479VI states that, "Stabilization for the main regulator is achieved by connecting an external capacitor CEXT to the VCAP1/VCAP2 pins."I interpret this as a series connection, like this,Table 19 gives some more information,It mentions "the two 2.2uF Vcap capacitors...", are they bypass capacitors that need to connect to ground, one for each pin? I looked around online and found people using this scheme, Which scheme is correct?Should I adjust the total capacitance to be 2.2u for the second scheme i.e 2 x 4.7uF would be OK?Using two capacitors (as above) would decouple RF and half the ESR, which are both useful.Regards, 

Hello,I'm using a STM32F479VI but I do not need the DSI (display) functionality for my current application.It seems that block runs on a independent power supply derived from VDD.Can I leave the DSI power pins floating or should I power them anyway?
