Hello,even though I have selected an external QSPI loader, at "Erasing & Programming" the firmware is not uploaded to the external memory, the programmer loads it to the internal memory.Why this?Thank you 

So, the issue is as follows, according to datasheet the timer for pin B14 AF1, which is the PWM signal I believe, is the TIM1_CH2N. I have gone out of my way to try and output something, I just can't seem to understand what the problem is#define AF01 0x01   void ms_delay(int ms) { while (ms-- > 0) { volatile int x = 500; while(x-- > 0) __asm("nop"); } }   void setup() { RCC->AHB1ENR |= 1<<1; //Enable clock for GPIOB RCC->APB2ENR |= 1<<0; //Enable clock for TIM1   GPIOB->MODER |= 1<<29; //Set pin B14 to alternate function GPIOB->MODER &= ~(1<<28);   GPIOB->MODER |= 1<<0; GPIOB->OTYPER &= ~(1<<0);   GPIOB->AFR[1] |= AF01<<24; //Set the alternate function register for pin 14 to 0001   TIM1->PSC=0; TIM1->ARR=255; TIM1->CNT=0;   TIM1->CCMR1 |= (1<<13)|(1<<14); //Set channel 2 to pwm mode 1 TIM1->CCER |= 1<<4; //Enable channel 2 TI

Hello, In the product specification STM32WLE5xx/STM32WLE4xx, december, 2022 DS13105 Rev 12, we can find on page 137 a recommended footprint in Figure 32 for the UFQFPN48 casing.But, we can also download the footprint of this casing in the CAD Ressources, for example link: STM32WLE5CC - Sub-GHz Wireless Microcontrollers. Arm Cortex-M4 @48 MHz with 256 Kbytes of Flash memory, 64 Kbytes of SRAM. LoRa, (G)FSK, (G)MSK, BPSK modulations. AES 256-bit. Multiprotocol System-on-Chip. - STMicroelectronicsThe both footprints are not identical (pad dimensions etc...).Why do we have 2 footprints for the UFQFPN48 casing ? Could you tell me the best footprint to use? Thanks in advance, regards, Daniel.

HI,I'm new here.I found that three adc can be configured for alternate use by querying the STM32F7xxx datasheet.But But I have encountered some difficulties. I hope someone can explain it to me.Tell me how to use ADC_TRIPLEMODE_INTERL. The following is the program I tried to configure, but failed.Thank you.

Hi, I have to develope a system where an stm32 connected via ethernet handles files stored in a sdcard through an FTP connection from a PC.I know there is a sample from ST exactly about this but I can't get it to work on my nucleo H723 board, it seems that somehow the generated files from cubemx are totally scrambled, different content and placed in different locations.Infact if I try to setup a project using cubemx as found in an online blog the project is generated but I cannot find ethernetif.c under src folder for example...Could you please help me and show me the right directions?thanks

Hello,when i select the newer Toolchain "GNU Tools for STM32 (10.3-2021.10)" instead of the one that worked until now "GNU Tools for STM32 (9-2020-q2-update) i get some Linker Errors. The exact same Code builds fine on the older Toolchain but throws those Errors on the newer one.Console Output:23:30:06 **** Incremental Build of configuration Debug for project STM32F030F4P6 ****make -j24 all arm-none-eabi-g++ -o "STM32F030F4P6.elf" @"objects.list" -lstm32f030f4p6 -lcmos0 -mcpu=cortex-m0 -T"C:\Users\Admin\Desktop\Projekte\Embedded\Dev Board STM32F030F4P6\Software\STM32F030F4P6\STM32F030F4P6 Dev Board Linker Script.ld" --specs=nosys.specs -Wl,-Map="STM32F030F4P6.map" -Wl,--gc-sections -nostartfiles -nodefaultlibs -nostdlib -static -L"C:\Users\Admin\Desktop\Projekte\Embedded\DeviceDriver\STM32F030F4P6\API\Lib" -L"C:\Users\Admin\Desktop\Projekte\Embedded\CMOS\API\Lib" --specs=nano.specs -mfloat-abi=soft -mthumb -Wl,--start-group -lc -lm -lstdc++ -lsupc++ -Wl,--end-groupc:\st\stm32cubei

I'm running STM32CubeIDE on a Ubuntu 18.04 system. I've switched it to dark mode for programming, but any "#if" preprocessor directives in the code have a light background. Which, makes it impossible to read. I've looked through all the properties on syntax coloring, and I don't even see a place where I can choose a background color for preprocessor directives.I'd happily install another theme, but I'm not sure how I'm supposed to do that.Here's a screen shot: https://i.imgur.com/CuaDg4E.png

I have to buy a new laptop (HP Pavilion 14-dv2003nl) and it is installed Windows 11. In some old questions (1 year ago) I read that developers of ST haven't yet produced a supported version for Windows 11, but it could work anyway. Is there someone that uses STM32CubeIde on Windows 11 and how works it?

hello, I am connecting the STM32MP157C to the debugger using STDC14 CN1 connector in JTAG mode. Please tell me the pin/signal direction, with regard to the debugger, for the following: Pin 4, T_JTMS Pin 6, T_JCLK Pin 8, T_JTDO Pin 10, T_JTDI   The connection fails using the CubeProgrammer. I get the following message: "ST-LINK error (DEV_UNKNOWN_MCU_TARGET)". On the debugger the PWR led lights green and the COM led lights red. The signals I am using to connect are: T_JTMS, T_JTCK, T_JTDI, T_JTDO (STM32MP157C to debugger) and also providing 3.3V to pin 3, T_VCC and of-course connecting the GND pins. I am not connecting STM32MP NJTRST pin to pin 12, T_NRST in the debugger (the STM32MP has an internal PU on it). The STM32MP157C boot mode is JTAG (although doesn't work in USB boot mode).   What am I missing here?   thanks Gil

Hello,In the wiki I have found these lines:5.3 Non-volatile counters↑Each certificate embeds a non-volatile counter value that is checked to control anti-rollback mechanism.There are two non-volatile counters: - Trusted non-volatile counter - Non trusted volatile counterOn STM32MP1, TAMP monotonic counter is used to store the backup value, which requires backup battery to maintain the content. It is mandatory to align the same value between trusted and non-trusted value as only one counter is used as reference.Source: https://wiki.st.com/stm32mpu/wiki/TF-A_BL2_Trusted_Board_Boot#Non-volatile_countersI'm afraid, we are implementing secure boot, but we are not planning to use a battery. VBAT won't be maintained when the board is off. And so content won't be maintained.Instead, we connected VBAT to 3V3 and we added a 100nF decoupling capacitor.What is the impact on the secure boot? Would it be working in that case, even if TAMP is not powered?Thanks,Best regards,Charles

Hi,I am trying to have data at a specific location in flash. To do this I have defined my section in the linker script as follows: .info_data 0x08004674 : { . = ALIGN(4); KEEP(*(.info_data)) . = ALIGN(4); } >FLASHwith FLASH starting at 0x0800 0000 and having a size of 18KB.The data to be placed is defined in a .h file like this: uint32_t volatile const info __attribute__((section(".info_data"))) = 0x12345678;This works, but it causes the file to be significantly larger. If I don't inlcude the data, the hex file ends at address 0x0800 3820, so well within the 18 KB range. However including this data causes the linker to stop with the main code at 0x0800 307C, places info_data at 0x0800 4674 and then places the rest of the code from 0x0800 4678 to 0x0800 4E1C. (I extended FLASH to 20KB size, to test this).Why does the linker leave so much empty space between the start of info_data? Is there anything I can do to minimize this? I tried with -fno-function-sections and -fno-data-sect

I'm writing C++ code wih STM32CubeIDE. Version of IDE is 1.11.0 and it comes with arm-none-eabi-g++ version 10.3-2021.10 . The compiler has some of C++20 features and I'm using them in the code.The problem is some of them are not recognized by the IDE although the code compiles and runs flawlessly.I can give3 examples that STM32CubeIDE has problem with them.Spaceship operatorConceptsConstraints

I'm trying to develop a 400V 3 phase inverter for a motor controller. I was looking at TD350E to drive the IGBTs. Can this be used on the high side or in a half bridge configuration?

Hi,I am approaching for the first time with STM32nucleo board and I am using STM32CubeIde. The debug tool provides a simulator to test if the firmware is working properly? I mean a simulation tool like that of MPLAB IDE for PIC microcontrollers which provides a simulation tool in the debug mode. Thank you very much.Regards.

It is written in the STM32U575/585 reference manual (see below) that the data is sent to the external device over the SO(IO0) signal and that The data received from the external device arrives via SI(IO1). Now, SO is known as Slave Out but here it is used as Master out, so I would expect t to be called MOand SI is known as Slave In, and here is used as Master in, so I would expect t to be called MI.Should I disregard the confusing names and use IO0 for MO ad IO1 for MI? Thanks

Is there a list someplace of pre-certified NFC modules which use ST25 chips?Thanks,Scott
