Solved

Posted on January 26, 2018 at 16:55Hi there,we are currently developing the firmware for our custom board with an STM32F746 MCU in LQFP-100 package. Our current version is working well and now we want to be able to download updates via USB DFU. I read many posts and the related documents from ST, so there might be some ways to realize this. Unfortunately, in either way we get stuck on  choosing the right addresses or verifying code with DfuSe. My favorite way is the following in which we jump to the internal bootloader:&sharpdefine SYS_MEM_ADD                              0x1FF00000 //Disables the RCC (reset setting)HAL_RCC_DeInit();SysTick->CTRL = 0;SysTick->LOAD = 0;SysTick->VAL = 0;// disables every IRQ__disable_irq();// remap system memory to 0x0000 0000SYSCFG->MEMRMP = 0x01;JumpToApplication = (void (*)(void)) (*((uint32_t *)(SYS_MEM_ADD + 4))); __set_MSP(*(__IO uint32_t*) SY

i am beginner with stm32 so please suggest which one is better or any other low cost module following are link 1) http://www.dnatechindia.com/Development-Board/STM32-development-boards/STM32F0308-Nucleo.html2) http://www.dnatechindia.com/Development-Board/STM32-development-boards/stm32f0308-discovery.htmlsuggestion are welcome an thanks in adavnce

Hello.My MCU does not work. I guess it is oscillator problem.- PF1 pin of STM32F373RC is low even though 3.3V power is supplied to MCU, so 8Mhz oscillator does not work. - The oscillator has internal capacitors and part number is "CSTNE8M00G550000R0"- I designed this circuit board. I used MCUs of Atmel, TI and Microchip for several years but this is first time to use STM32 MCU.- I checked 3.3V power is normal and NRST pin value is HIGH.- There is no other oscillator for LSEDid I make a mistake?Please let me know some way how can I check this issue.Attached image is oscillator part of my circuit.

I'm trying to erase a single page of flash memory at 0x0800F800 (on a 64kB STM32F103C8T6) by using the following code, which runs from RAM:while(FLASH->SR & FLASH_SR_BSY); FLASH->CR = FLASH_CR_PER; FLASH->AR = 0x0800F800; FLASH->CR |= FLASH_CR_STRT; while (!(FLASH->SR & FLASH_SR_EOP)); FLASH->SR = FLASH_SR_EOP; FLASH->CR &= ~FLASH_CR_PER;The problem I am facing is that EOP is never set to 1, as well as BSY flag in FLASH_CR is never set to 0. The erase procedure hangs indefinitely, and when this code was previously executed from flash (not RAM), it also caused a full lock-up of the MCU with inaccessible SWD debugging.I tend to think that this might be a hardware failure of my specific MCU. However, what makes me doubt about it is that mass erase and/or page erase, flash programming and verification all works from OpenOCD and ST-Link Utility when the MCU is reset and halted prior to trying to execute flash operations in firmware.What could possibly cause

Hello,In the RM0433 (rev 3) the DBGMCU_APB4FZ1 offset is incorrectly marked in the detail section.It is 0x04C and should be 0x054.The register summary is correct. But if somebody is using the detail section - can make an error.BTW: What does the LS stand for in WDGLSD1 (related to other question I posted)?

I have installed VCP_V1.5.0 Setup for Windows 7 and 8, but neither works. Please help. Is there a separate driver for Windows 10?

Hi,Has anyone successfully used sensortile(soldered on small cradle) with Unicleo GUI ? If yes which firmware should be used to interface sensortile with Unicleo GUI ? In "Release Note for X-CUBE-MEMS1 Software for STM32, Expansion for STM32Cube" support for sensortile is mentioned as follows :Projects X-CUBE-MEMS1 Examples for SensorTile V4.3.0 (release notes) But I could not find this particular firmware in the firmware package(X-CUBE-MEMS1 ) .What am I missing ? Any help on above would be appreciated.Thanks.

Hi gent'ssorry: my first post here, hope everything goes well.I would like to redesign an antenna for an 95HF, today for test, we use a Nucleo board and it's working pretty well; but I think we can do better.We need to read 2 tags: one on the Wafer Pod case; one inside the case, on the cassette. distances are in the range of 10cm but unfortunatelly tag inside Pod is prety at 90°.I read carefully AN3394 and think I basicaly understood what I should do to adapt impedances;but now I have to design my antenna according also to the space I have in front...I saw ther is a 'simplified software tool' (antenne.exe) but I was not able to find it for download.Any comment, help is welcomme.Thanks and regardsJMI

Upgraded ST-Link to V2.J29.M18 STM32 Debug+Mass storage.STM32 ST-LINK Utility is v4.2.0.0 USBDriver v5.0.3.0 CLI.exe v3.2.0.0Removed both ST link jumpers .Fresh CR2032 battery installed on STEVAL-SmarTag1Connected directly on SWD (pin 1 correctly aligned)Message Can not connect to target!ST-Link V2 is connected to Nucleo L476 board.ST-Link does connect to this board when ST-links reinstalled.I have also tried a separated ST-Link V2. Also no connection to SmartTag1How do I connect to the STEVAL-SmarTag1 to change firmware from default?

Just upgraded to 5.8.0 (the ONLY and LAST available version on ST website), and we ran into a lot of troubles. First of all, SPC5STUDIO updates URL had to be fixed because of the lack of trailing "/". Once fixed, we're still unable to install/update/download anything because of a 404 error. Who's the guy in charge of tests ?Before replying by a "please update to 5.8.1", be aware that there's no "5.8.1" version available at the ST website :Where's that 5.8.1 ?

I am trying to achieve read range of 10cm or more on an antenna attached to M24SR chip. I am currently getting a read range of 5.5cm How can I increase the read range?Thanks in advance.

I need to specify an RFID IC for bidirectional data exchange with an Android mobile phone. I will be using the NFC to update the firmware on an MCU in the system with a flash size of 32kB. The other application is the for the system to transfer up to 64kB of data to the phone. I'm finding it difficult to understand the differences between the ST25 chips, some use case examples would be helpful. Thanks for any advice.

i am using the STM32L4 Nucleo board L4R5ZI .i am trying to configure i2c to read time from the RTC DS3231.but i am getting only data as zero.what may be the issue.i have attached the code.kindly help..

I'm having problems to read my current sensor, which is located at the source leg of a power transistor. I'm using the sensor TLI4970This is my routine every 10ms:HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_RESET); //Bring slave select low   HAL_SPI_Receive(&hspi1, (uint8_t *)&SPIRx, 2, 10); //Receive data   HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_SET); //Bring slave select highHowever, I get random values even when the current is zero. I'm getting values like:0x88000x88030x88010xA7FF0x87FC0x97FE0xA8020xA8010x97FD0x87FD0xA8000xA7FEAccording to the datasheet, these are sensor status messages, but none of them are Sensor Current Messages. The hardware seems okay. This sensor is not so common I think. I haven't found much help. Am I doing something wrong in software?

Hello,I'm following this guide (https://mcuoneclipse.com/2015/08/22/debugging-stm32f103rb-nucleo-board-with-with-segger-j-link/)The board I am using is NUCLEO-L4R5ZI. I've connected the following pins to the 10-pin ARM connector: I've also tied the VDD_Target/VTref pin to 3.3V. When I launch Keil uVision5, I go to Project options and select the debugger. I am getting a "RDDI-DAP Error". Please do not suggest I use the built in ST-LinkV2 debugger as a solution. Thank you for your help!

I have F303RE.The pin config are:The ADC config is:The Adc init code is generated as well the Analog Gpios. That is not a problem.I want to read one after each other. I added a function to select to config, but I dont know what SHould I pass the rank or the channel (or both). Here is the Adc select channel or rank function.void select_adc(uint32_t rank_or_channel) { ADC_ChannelConfTypeDef sConfig; sConfig.Channel = rank_or_chammel; // ADC_CHANNEL_1; sConfig.Rank = rank_or_chammel; // ADC_REGULAR_RANK_1; sConfig.SingleDiff = ADC_SINGLE_ENDED; sConfig.SamplingTime = ADC_SAMPLETIME_1CYCLE_5; sConfig.OffsetNumber = ADC_OFFSET_NONE; sConfig.Offset = 0; if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK) {   _Error_Handler(__FILE__, __LINE__);   }   }    And here is how do I call it. int RORC=1; // PA0=1 PA1=2 PA2=3 while ( 1 ) { HAL_ADC_Start(&hadc1); select_adc(RORC ); if(HAL_ADC_PollForConversion(&hadc1, 1000) == HAL_OK) {

I have 3 of the ST25R3911B-Disco boards and they are working great with discovery gui version 1.1.22.0 on a windows 10 pro machine. I needed to set up a second pc and can now only get the gui version 1.2.2 when I try to connect to the new version I first had to upgrade my boards according to the new gui. But I could not do this using the version 1.2.2 it keep failing. I used my gui version 1.1.22 and was able to update the board with the 1.2 version firmware but when I try to use the version 1.2 gui it works a couple times then gives me a packet info error and drops out. If I connect the board with the 1.2 firmware to the gui with the 1.1.22 everything is good. Any ideas on what he issue could be? How can I get the gui version 1.1.22 since is seems to work better than the new version?

Why does STMCubeMX (version 4.27) not provide I2S configuration for STM32F3xx parts?I have inspected the underlying F3 firmware source (current version) and all the I2S registers for SPI2 and SPI3 are present however the HAL driver source is hard coded to force any SPI interfac with I2S support to always be in SPI mode.Is there an issue with STMCubeMX or is the I2S feature in STM32F3xx series MCU's broken and STM is preventing us from using it?...

Hi. Can you help me to get last version cube mx under Windows XP. Thank you.

Getting this error when trying to install flash memory or eeprom emulation software from eclipse marketplace in spc5 studio. ver 5.8.0Thanks in advanceRegards:

I am using a STM32F072 microcontroller with a matrix keypad. The matrix pins are essentially bit banged, using ODR mask commands. When I set up a timer(doesn't matter which one) and I use the timers interrupt (update and a single capture compare) to toggle a pin (manually) it seems to be late processing some of the capture compare and update interrupts. This results in a waveform that looks like this:Even weirder it doesn't appear to have anything to-do with the speed of the interrupt, as I get the same result at 100KHz as I do 1KHz (as seen above).The code to setup the timer is as follows:CR1().UDIS() = true; //Disable updates CR1().CEN() = false; //Disable counter CR1().CMS() = 0; //Edge aligned mode CR1().DIR() = 0; //Up-Counting CR1().OPM() = false; CR1().URS() = true; //Only update on overflow or underflow or DMA request CR2().CCDS() = false; CR2().CCPC() = false;   auto const prescales = CalculatePrescale(System::SystemClock_t::Timer(), pFrequency); ARR()

I use STM32 workbench for previous project and TruStudio for new project, when I copy some source code to TruStudio, it is not align properly, is there any shortcut for TruStudio can do alignment easily?
