Posted on March 07, 2018 at 14:38 Hello, I'm currently designing a custom bootloader and get stuck during the 'Jump to App' function. I was recognizing, that there are a lot of community entries concerning that topic. I was reading and trying various topics, but unfortunately nothing really worked for me. Maybe anyone of you can give me the golden hint? I'm using System Workbench for STM32 and want to implement my code on the STM32L431 device. In the *.ld file of the bootloader I added regions FLASH2 and MAGIC: /* Specify the memory areas */ /* Attention: Different sizes for different types of the controller (flash size!) */ MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 64K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 26K FLASH2 (rx) : ORIGIN = 0x8006800, LENGTH = 254K - 26K -2K MAGIC (rx) : ORIGIN = 0x803F800, LENGTH = 2K }�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? FLASH2 will hold the app, MAGIC holds some bootloader specific data. After readingAN3965 (esp. page 11), I cha

Posted on February 24, 2018 at 20:30Hello,I've been working with the ST25RU3993  on a user board design and have not yet been successful in getting the PLL to lock.  I've tried to set the VCO range both manually and with the auto command.  I've tried a variety of combinations of carrier frequency/base frequency/reference frequency settings.  In trying to troubleshoot the problem I've noticed that I only get a voltage waveform on VDD_B with the default PLL settings and a reference frequency of 100kHz.  Attempts to calculate the N divider and change the settings in registers 17, 18, 19 result in reading of zero on VDD_B.  In all testing so far I have only seen a few millivolts on VDD_A, however I understand that could be just because the PLL has not locked yet.  Can anyone tell me what I should expect to see on VDD_B as I seek the correct N divider and a locked PLL?  Is it even reasonable to assume I can infer anything about the PLL

Posted on March 05, 2018 at 15:46Hi I am using Atollic studio and the STM32F769 Discovery board.I removed resistor R93 and fitted a 0R link to R92 so that the SWO line is connected to the ST-Link on the discovery board.I have followed this tutorial to enable SWV and make use of ITM_SendChar:http://blog.atollic.com/cortex-m-debugging-printf-redirection-to-a-debugger-console-using-swv/itm-part-1 I have enabled SWV and set the core clock frequency: currently 200MHz. (I verified this by calling SystemCoreClockUpdate() and checking the value of SystemCoreClock 200000000)I have set the SWO clock to 2000kHz.Unfortunately i do no receive any characters in the SWV console window within Atollic.If i breakpoint the ITM_SendChar function i can see that its getting to the line 'ITM->PORT[0U].u8 = (uint8_t)ch;' without issue.I also just tried the 'STM32 ST-Link Utility' with SWO viewer and can see a few characters when I press start but do not see a continuous stream of characters

Posted on March 03, 2018 at 18:04 Hi, I beleive i have initialised my master STM32 correctly somehow i cant get my slave to understand my master.

Posted on March 05, 2018 at 15:19 I have Nucleo-144 Board with a STM32L496ZG and use it for evaluation if the MCU will work for us. But I´m stuck with the CAN initialization.

Posted on August 06, 2017 at 19:22Hello!!I post an  .IOC file that  produces initialization code for Keil v5.This file produced with 4.22 version of CubeMX and uses the latest firmaware for L1 family.At module, gpio.c and especialy inside called function LL_SYSCFG_SetEXTISource(LL_AHB1_GRP1_PERIPH_GPIOA, LL_SYSCFG_EXTI_LINE0); , the first parameter, LL_AHB1_GRP1_PERIPH_GPIOA  is not correct.Inside the module stm32l1xx_ll_system.h,  contained the right parameters must put.This parameter has value 0x01, but the correct LL_SYSCFG_EXTI_PORTA  has value  0x00.This cause problem to set the correct source of EXTI interrupts.#ll #stm32cubemx

Posted on November 15, 2017 at 10:57 Hi, I have ADC set like so (Code generated by CubeMX): sConfig.Channel = ADC_CHANNEL_1; sConfig.Rank = 1; sConfig.SamplingTime = ADC_SAMPLETIME_2CYCLES_5; sConfig.SingleDiff = ADC_SINGLE_ENDED; sConfig.OffsetNumber = ADC_OFFSET_NONE; sConfig.Offset = 0;�?�?�?�?�?�?�?�?�?�?�?�? However this fails in stm32l4xx_hal_adc.c file in function: HAL_StatusTypeDef HAL_ADC_ConfigChannel(ADC_HandleTypeDef* hadc, ADC_ChannelConfTypeDef* sConfig)�?�? Specifically assert on assert_param(IS_ADC_REGULAR_RANK(sConfig->Rank));�?�?�?�? I assume generated code should look like this: sConfig.Rank = ADC_REGULAR_RANK_1;�?�? Is this correct or am i missing something about this part of code?

Posted on October 04, 2017 at 11:52Hi,Currently the defaults set for STM32F042 in STM32CubeMX v4.22.1, FW 1.9.0 for USB CDC will not compile after generation.This is because the USB CDC Rx and Tx Buffers are set to 2048B each by default, which is too much considering the micro has 6kB RAM. In previous versions this was set to the minimum 4B and caused no problems (at least for me).Can you please update the defaults to be compilable by default?Thanks P.S. It took me quite a long time to figure this out, and it was only thanks to having a project I created with cube before.#stm32cubemx #stm32f042 #usb-cdc #defaults

Posted on July 02, 2017 at 02:49I am using STM32CubeMX 4.21.0 with the STM32L4 HAL library version 1.8.1.It seems that the Src/usb_device.c includes code with customization points (e.g. HAL_PCDEx_BCD_Callback() has a user code comment block) but there are no customization points within the file at global scope for adding things like headers, variables, function declarations or definitions.  Is this an oversight?Please add customization points at global scope in this file.#stm32l4 #stm32cubemx #pcd

Posted on March 04, 2018 at 11:18I tried to transplant the mbedtls ssl server code for stm32f769i discovery board to stm32f746g discovery board. The error was printed on to the lcd. I.E. the headers are changed and the BSP is changed. The error is found to be from mbedtls_mpi_grow(), from inside of which mbedtls_calloc (which in my case is calloc) returns NULL, so that screen message is:mbedtls_pk_parse_key_returned -16912.Is there any example of using mbedTLS with stm32f746G-discovery board?#mbedtls-stm32f746g-discovery

Posted on March 03, 2018 at 21:15I need to run the board on 1.8 v.I found https://www.eevblog.com/forum/microcontrollers/using-stm32f4-discovery-board-on-1-8-volt/ thread about the changes need to be made to the board. However, it is not clear to me how to: Program the board when on 1.8 v, using JLink v8. Do I need to perform any hardware modification or can I connect the programmer using SWD pins directly to the board.Use UARTHas anybody had any experience with running STM32F4 microcontrollers  on 1.8 v?#stm32f4 #1.8v

Posted on February 18, 2018 at 18:35Hi,I get troubles to start with my new IDW01M1 module.I use it with the NUCLEO-L053R8 board, but none of applications provided with the WiFi CubeExpansion package works with my hardware.For example, I load the 'WiFi_VCOM' application to the main board. The application launches, but it cannot set the connection with WiFi module at start (message 'Error in baud-rate auto-detection...' on termnial).Again, with the 'Client_socket' application: it starts, ask for identifiers, and freeze at WiFi module initialization.It seems that there are no communications at all with the module.I tried Resets on both boards, and Factory setting reset on WiFi module (set GPIO0 high at start), without success.Jumpers are placed on JP3 and JP4, no jumpers on JP1/JP2LED1 is on, LED2, LED3, LED4 are off.Does I missed something obvious, or my hardware is broken ???#x-cube-wifi #spwf01

I'd like to integrate the MCU that I've been using into my final system(i.e no dev board) I've designed PCB's in the past, but this feels a little more up there, so I just want a few checks I've read the documentation although this is what I've gathered: Documents used: http://www.st.com/content/ccc/resource/technical/document/datasheet/group3/d6/11/13/15/f4/38/49/79/DM00330506/files/DM003305pdf/jcr:content/translations/en.DM003305pdf http://www.st.com/content/ccc/resource/technical/document/application_note/b0/5c/ba/b2/cb/10/41/dd/DM001645pdf/files/DM001645pdf/jcr:content/translations/en.DM001645pdf http://www.st.com/content/ccc/resource/technical/document/application_note/b9/9b/16/3a/12/1e/40/0c/CD001675pdf/files/CD001675pdf/jcr:content/translations/en.CD001675pdf This is an overview of me designing the necessary hardware to get a device up and run
