            I made external flash loader for STM32H735G-DK. I’m able to read, write and erase flash. However, programming 1M of flash takes ~ 50 seconds. STM provided loader takes around 7 sec for the same. Octo SPI in both cases, clocks are the same- verified, DTR in both cases- verified. I am testing on the same board, the same STLINK, so hardware is not limiting factor.Would anyone have an idea what method STM loader uses for such a huge speed improvement?

Hey, I'm using a NUCLEO-G031K8 board. I currently have jink running on it, and I can easily run debug and program with the USB interface. I'm currently trying to flash it using an external jink EDU programmer, and I have also tried by buying a larger NUCLEO Board and snapping off the programmer to program it. All these seem to connect to the NUCLEO, but they all error when they try to erase the board. Do I have to connect Solder bridge 2 (st-link reset).Or is there another Configuration I have to do with the hardware?I have already soldered on the 5 programing pins, and also edited the NRST register so that it is not acting as a GPIO pin.any help would be gladly appreciated. 

I have already purchased P-NUCLEO-53L8A1 and VL53L8CH. How should I join them together and read out the histogram data. Can you provide a detailed guideline or experiment video for me? 

I am using my custom board PCB with STM32F103C8T6 MCU. I want to give a PWM signal to PB1 pin & want to set PB2 pin to HIGH. While giving the PWM to PB1, although I set PB2 pin status as HIGH, when I measure the voltage of PB2 pin it shows '0V' value. I am using keil uvision to developed the firmware. How do I solve this problem? Can I set PB2 to HIGH while giving a PWM to PB1? 

Hello,I need to implement delay macro, lasting just a few cycles.As the delay is so small I would not like to use TIMs o DWT.On Texas Instruments DSPs, I was used to implement this nanoseconds delays, using NOP() instructions.Unfortunately, as also written in STM32 Programming Manual this is not a good pattern on Cortex processors.On a previous post, related to another issue, I was suggested to use Data Memory Barrier (DMB), Data Synchronization Barrier (DSB), and Instruction Synchronization Barrier (ISB) instructions, instead of NOPs.How can I use this instructions, to implement a few cycles delay macro?Regards,Carlo

Hello,i need help how to edit linker file for placing array on specific address in external SDRAM connected via FMC.I'm working with 7" TFT 800x480 @ 24bpp via LTDC controller and i have configuration 2 layers and both double buffered. So in HW is connected external SDRAM 8MB four banks (2MBx4). I would like to use each bank for one buffer as recommended in AN4861 https://www.st.com/resource/en/application_note/an4861-lcdtft-display-controller-ltdc-on-stm32-mcus-stmicroelectronics.pdf.I added SDRAM and SDRAM section into linker script as follows:SDRAM (rwx) : ORIGIN = 0xC0000000, LENGTH = 8192K.......sdram (NOLOAD) :{. = ALIGN(4);*(.sdram .sdram.*)} > SDRAM But i don't know how to place four buffers into start address of each SDRAM bank.I tried to create 4 SDRAM sections instead of one:SDRAM0 (rwx) : ORIGIN = 0xC0000000, LENGTH = 2048KSDRAM1 (rwx) : ORIGIN = 0xC0200000, LENGTH = 2048KSDRAM2 (rwx) : ORIGIN = 0xC0400000, LENGTH = 2048KSDRAM3 (rwx) : ORIGIN = 0xC0600000, LENGTH =

Hi,I'm using STM32G070RBTx, and I use this formula from document RM0360 to compute temeperature:From page 56 of document https://www.st.com/resource/en/datasheet/stm32g070cb.pdf, I'm using:Avg_Slope = 2.5 and V30 = 0.76.The temperature converted value I obtain at ambient temperature appears reasonable ( 21 °C approx. )  but when the temperature increases the  raw value I get from ADC also increases but using formula above gives a decreasing temperature value and this is wrong.Please help.

According to AN5192 (last paragraph of page 50) if LIR is enabled (0x56:0x4F)  and SINGLE_DOUBLE_TAP is set (0x5B:0x80) "latched mode is applied to the double-tap interrupt signal only".But I only read single tap in TAP_SRC (0x1C:0x20) during ISR.As soon as I disable LIR I get both interrupts.Is there an error in AN5192 and only single tap will be signalled when LIR = 1?Or I made a mistake somewhere in the registers?Here is my register dump:# i2cdump -yf 1 0x6a 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: 00 00 3f 00 00 00 00 00 00 00 40 00 00 08 00 6c ..?.......@..?.l 10: 60 28 44 08 60 00 00 00 e2 20 02 0f 00 20 07 28 `(D?`...? ??. ?( 20: b3 01 0d 00 ee ff f5 ff b2 01 23 00 63 41 00 00 ???.?.?.??#.cA.. 30: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 40: cd 05 20 00 f3 05 20 00 00 04 00 00 00 00 00 00 ?? .?? ..?...... 50: 00 00 00 00 00 00 4f 06 86 06 8a 80 00 00 4a 00 ......O?????..J. 60: 00 00 00 fd aa 01 00 00 00 1a 21 21 40 06 00 00 ...???...?!!@

I was trying to fabricate a flexible NFC antenna for m24lr chip. Initially, I fabricated my design on a copper PCB. It worked perfectly fine with my NFC chip and facilitated NFC communication. I observed its S11 curve using a NanoVNA with a loop probe, and it showed the minimum of the curve within the expected frequency range (around 13.6 MHz).When I fabricated it on a flexible substrate (PET,) using silver nanoparticle ink, I found that the minimum of the S11 curve was lost. The antenna still worked fine with the NFC communication, but I got a flat curve everywhere, from 5 MHz to 50 MHz (I did not observe beyond that range.)I measured the resistance of the flexible antenna and found that it has nearly 600 ohms of internal resistance, whereas my PCB antenna had about 2 ohms of resistance. Then, I connected my PCB antenna in series with a variable resistor and observed the S11 curve while varying the resistance of the variable resistor. I noticed that as the resistance increased, the mi

Hello all.I have a question about how to use KMS_GenerateKeyPair() function. There are no examples in the code, and API description is not really enough for my little brain. Could somebody provide me an example on how it should be used? What kind of parameters, how to initialize them and so on. I would be grateful!

Hello,      I have a board based on the stepper driver L6472. I noticed that, when I do not provide input 12V for the motor (the motor 12V but I provide the 3.3V for the logic (VREG, VDD, SW), I find a voltage of about 2.6V on the VSA, VSB pins. I tried to exclude all other possible source on the board and I think that this voltage is produced by the L6472. To have a definitive confirm I should cut some PBC track. Before doing this I would ask if it is an expected behaviour (to have 2.6V at motor output). 

I am a beginner, I am programming a stm32F411RE with Keil 5, when I was configuring the USART transmitter, Hercules and Arduino did not show any data, I reviewed several videos and I have the same problem, it has been several days.

I have initialized a project with STM32CubeIDE (the .ioc file) using the STM32F407G discovery.I want to produce on an output pin of the TIMER4 a PWM signal with a certain duty cycle, so I set in the .ioc file the various parameters and in particular the "Pulse" parameter which, if I am not wrong, takes values in the range [0 .. ARR]. The value 0 corresponds to 0% Duty Cycle while the value ARR corresponds to 100% Duty Cycle. Is this correct? Since I want to be able to change the pulse parameter dynamically without having to set it every time by opening the .ioc file ... I decided in the main.c to directly change the register responsible for the Pulse parameter. So in the Reference Manual I looked up what it was and I found "one pulse mode" (in the attached reference manual, see section 18.3.10). I have read it several times but I can't figure out which register stores the Pulse value of TIMER4.I found out "indirectly" that it's CCR3 register because, during the simulation/debug, i

Hi,From the following repo https://github.com/STMicroelectronics/st-mems-android-linux-sensors-hal/tree/masterI would like to know if the driver it's compatible with an Android environment under snapdragon where all the sensors part is managed under the ADSP and the SSC core library. On this systems the sensors part is managed trough the SSC Framework who handles the sensor core functions.Does anyone have experience with it or know if it is compatible?Thank you.

I'm working on a custom board with a F446RET6 and testing through some code bits. I've been able to successfully test that the board programs and functions with a led-blink style program. My problem is that I'm attempting to use CAN2; I'm trying to test via loopback but I'm having issues getting any type of IRQ for a receive. I feel like its something basic I'm missing here but after reading through some other posts I'm either brain-dead or missing something.currently using the HSI clock but I wouldn't think that would matter for loopback testing (understand for the "real" thing would be best to use the HSE).RX GPIO is set to pull-upVerified (after looking at some old posts using an older version of Cube) that the CAN1 clock is being initializedAlso I understand that the "CAN2" device is really the "slave" to CAN1. I've got my slave start for the filter set to 14 to split everything half and half and just arbitrarily chose bank 15:   hcan2Filter.FilterActivation = ENABLE

Hello, i am trying to interface TI's ADS8910 (18bit SAR ADC) to an STM32F730 via normal SPI, since i am unsure whether QSPI will work.I want to achieve the full 18 bit @1MSa, which is possible when working with 54MHz (/2 APB2 prescaler on the F730 which runs at full speed - 216MHz) and the ADC's zone 2 transfer. The HAL implementation of dma transfer is way to slow between consecutive readouts and thus gets stuck "busy" and "locked" forever after the first readout. Therefore i am currently trying to write everything myself. My question is regarding the SPI CR2 register, bits 6 & 7 (RXNEIE and TXEIE):Will the DMA requests, mentioned in Bits 0 & 1 (RXDMAEN and TXDMAEN) still be generated when the interrupts are masked?I don't want my program to be interrupted more than neccessary. the flow should be :F7 gets an interrupt that signals that the ADC has finished conversion and is ready to send the new data.SPI transfers 3x 8bits // or 2x 11bits (the ads 8910

Hello,I'm working on a cutom made board controlled by an STM32F303ZET, I figured out that I forgot to pull up D+ for USB communication, even doing it externally keep showing me this error. I tried to pull up the D+ using 3.3V directly and also by pulling another pin HIGH. How can I resolve this problem ? 

I have an eval board (Nucleo STM32U5A5) working with the CDC_ACM demo code (UCPD/USB_HS, which was written in 2021). I then created the CDC_ACM from scratch with the majority of IOC parameters's configuration copied over from the demo IOC and MOOC tutorial (for STM32H7xxxx); I noted many new parameters in the 2024 release, which I left untouched. I then copied over some USB code filename (using WinMerge) into new code (as suggested by MOOC for STM32H7xxxx). I refer to this as a new code/project. I found an issue with the static HAL_StatusTypeDef USB_CoreReset(USB_OTG_GlobalTypeDef *USBx); it times out after the core reset: CSRST is not cleared in the new code. However, the demo code does.  I have checked the RCC/PWR/USB/UCPD register flags (via SFR window) while under the breakpoint in USB_CoreReset and found all the same between the demo code and new code except the TYPEC_VSTATE_CC2 which shows 1 in the demo code but 0 in the new code.  I have reviewed the datasheet and manu

Hi, I have a question to the ST community. I'm currently working on a project including an ECU form a diesel engine. The ECU uses J1939 for communication. I need to be able to read messages en send to the ECU. To do that I'm using an STM3210E-EVAL. Is there a library or stack available to use with my STM32 board? I did look on the internet where I found some things, but is nog for my board or incomplete. I hope that someone can send me in the right direction. If you need more information feel free to ask. I'm new to the STM32 platform.

Hello,I am new to dual core processors. I was working on both cm4 and cm7. My main core was cm7. I accidentally disabled the cm7 core on Stm32CubeProgrammer and now I cannot connect to the board. Power comes and goes instantly.  (I normally use STLK to connect the board.) What can I do to make my board work again?
