Hello: I use this to check the address is application in stm32f207VET6.void go2APP(void) { uint32_t JumpAddress; pFunction Jump_To_Application;   //Check if (((*(__IO uint32_t*) FLASH_APP_ADDR) & 0x2FFE0000) == 0x20000000) { printf("APP Start...\n"); HAL_Delay(100); // Jump to user application // JumpAddress = *(__IO uint32_t*) (FLASH_APP_ADDR + 4); Jump_To_Application = (pFunction) JumpAddress; // Initialize user application's Stack Pointer // __set_MSP(*(__IO uint32_t*) FLASH_APP_ADDR); Jump_To_Application(); } else { printf("No APP found!!!\n"); } }When i erase the whole chip i get this But when i use jflash to program an application hex to the application address I get this Even i use the flash base address to check but also get 0x20020000 .Should i change the 0x2FFE0000 to 0x2FFD0000 ?Thank you

Hi,I've generated a code using CubeMx 5.1.0On MCU STM32F103C8T (Blue pill)I want to controll PWM duty pulses thru DMA in Circular mode.I want to use circular buffer and on half transfer I want to update half of an array that I sent thru DMA to TIMer for PWM.I was able to setup TIM with PWM and DMA. Now PWM is generated according to my array of dutys. Now I want to update array content on half and full transfer bu I don't hnow how to setup callback on such event./* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2019 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under BSD 3-Clause license, * the "License"; You may not use this file except in compliance with the

Hello,I am running example "OpenAMP_TTY_echo" on the board "stm32mp157c-dk2"I have modified the code a little bit so that channel0 (uart0) doesn't have to wait for a massage from linux side and transmit message every half second. It is sending the messages on every half second without problem.But the problem is now uart1 is not working. I mean on linux side if I write "echo "Hello Virtual UART1" >/dev/ttyRPMSG1" , I can not receive any callback message from the console. This means channel 1 is not working because channel 0 is blocking it. Is it normal ? Why normal ?while (1) {   OPENAMP_check_for_message(); " " " " VIRT_UART_Transmit(&huart0, Data, size); HAL_Delay(500);   if (VirtUart1RxMsg) { VirtUart1RxMsg = RESET; VIRT_UART_Transmit(&huart1, VirtUart1ChannelBuffRx, VirtUart1ChannelRxSize); }   }

I had using sample code "low power sleep mode", the current measure result is over datasheet spec, how to do can get datasheet value?The measurement result is around 1mA, the datasheet show 60uA.​Hardware paltform: NUCLEO-G071RBSoftware version: 1.3.0STM32Cube_FW_G0_V1.3.0\Projects\NUCLEO-G071RB\Examples\PWR\PWR_LPSLEEP\

Hi,Im using the System Workbench and a strange behaviour occured to me.When a certain halting point is reached, Im not able to step to the next one. Pressing Resume brings me back to the very same halting point, stepping over aswell. And stepping into always brings me to the Ethernet Interrupt Handler.Is this by design or a bug?

I am trying to make UART printf work with STM32F746-DISCO board.I tried running printf successfully with a default clock (whatever it is--I am not sure).I was doing it without using STM32CubeMX code generator.Now I found the code generator to be useful, I tried using the SystemClock_Config() function it generated for my board, which increases the clock speed up to 200MHz from my understanding.However, when I increase the clock speed with the SystemClock_Config() function, my printf does not work.Specifically, by using a logic analyzer, I figured that the baud rate becomes too fast, around 359689 (when I set it to 115200).I am attaching my main code below -- it is mostly just a stripped-down version of what STM32CubeMX gave me.If I comment out SystemClock_Config() from the code, the printf works fine.Can anyone help me with what is happening?Thank you

I use the CubeMX command-line interface. Normally I put my script in a file, and run it like this:java -jar "C:\path\to\STM32CubeMX.exe" -q "C:\path\to\myscript.txt"But before doing that, I test the script commands one-by-one in the interactive mode. That means, I start up CubeMX with the command line interface and I can see visually what happens upon each command I enter:java -jar "C:\path\to\STM32CubeMX.exe" -iThe first command I usually issue then is to load an existing `ioc-file`:config load "C:\path\to\my_cubemx_proj.ioc"Then I issue the following command:set mode FREERTOS EnabledThis works. I can see immediately the green checkmark appearing next to `FREERTOS` in the Middleware section. The next thing I do is changing the Timebase Source in SYS from `SysTick` to `TIM1`:set mode SYS TIM1 Timebase SourceThis used to work in the previous CubeMX version. But in CubeMX5 it doesn't have any effect. The following image illustrates what happens:

Dear All,I jump in boot mode with boot0 to high level, and i can test it with dfu USB connexion.Unfortunately, it does not work with UART3.I have the TX signal 0x3F coming from computer, but any acknowledgment. In STM32CUBPROGRAMMER, there is : "Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again..."I use an usb - ttl 3.3v cable which works, and I did not add pull up resistor because the signal is high by default.Any help would be greatly appreciated.Thanks,

Hi everyone,I use ST25R3911B with differential antenna driving using the circuit recommended in datasheet, powered in 3.3V.I initialize the chip with NFC-A mode. I can read NFC tag but in a very short range (maximum 15 mm).I tried to increase this range by increasing the receiver first gain stage, by writing in receiver configuration register 3 (boost mode) but it did not improve the read range.Is it normal that it did not increase the read range?Is there another way to increase it?Interresting facts: - The A/D converter output register value is not impacted by my change.  - As expeced, if I write the RFO normal level definition register to disabling first segments, the value of A/D converter output register decreases as the read range.Thanks a lot for your help

Hi,I am using Keil v5.28 and want to debug the code on STEVAL-SMARTAG1. The module uses 1.8V to power its MCU. SWD pins are enabled in the app.---------------------------After 4-5sec after starting the debugging of the STEVAL-SMARTAG1 module I loose the connectivity to the target (it works fine within the first 4sec). The watched variables are not updated since then. Tested both nucleo ST-LINK/2-1 (external target) and j-link edu mini:jlink reports: **JLink Warning: CPU could not be halted"st-link gives the following message when I try to stop the debugger or stop the app: "Could not stop Cortex-M device".So both debuggers experience very similar issues.VTref looks good: VTarget = 1.794VI have no problem to stop the MCU within the first 3sec. The problem starts showing up after 4sec.------------------I know that the j-link edu mini does not support 1.8V (at least theoretically because I saw it working with such 1.8V powered boards). So it may fail with this voltage as per Segger inform

I want to implement Remote Display of TouchGFX screen through web server. Is this possible like VNC? How can I implement if possible?

From the datasheet diagram (attached), it seems like the DMA has access to all of above. However, it is not clear whether it is really possible to DMA data to / from those and how I should do it and I've seen negative response to similar chips, so I am confused. Thank you!

So even newer STM32s still have both of UARTs and USARTs.My question is about how they are going to be supported in Cube libraries.Am dealing with H7x3 recently, and noticed that the UART example actually is for USART - as the serial connector on the eval. board is indeed USART1.https://github.com/STMicroelectronics/STM32CubeH7/blob/e261d820b398846a94f22f4aeb32d86c29546efb/Projects/STM32H743I-EVAL/Examples/UART/UART_HyperTerminal_IT/Inc/main.h#L33I've played with the example as is, and it works. Then out of curiosity I've changed all uses of "UART" lib API there to USART (added hal_uart.c, ...uart_ex.c to the project...) and RX interrupt no longer works. Output works well.It does not get any singe RX interrupt. In my real project both UARTs and USARTs will be needed.What we have in the HAL drivers?stm32h7xx_ll_usart.h is there, but no ll_uart.h/.chttps://github.com/STMicroelectronics/STM32CubeH7/blob/master/Drivers/STM32H7xx_HAL_Driver/Inc/And same in STML4 library. Is this simply omis

I have a uart setup that performs large transfers. I have seen that it blocks receive for most of the time this transmit happens. The IRQ is shared for both transmit and receive (by chip architecture). So how do I deal with this ?Is the usart really full duplex ?How does NVIC nesting play into this?

Hi together,I have a tinker board with a STM32F405RG (1024kB Flash 192kB SRAM, no FMC, no DMA2D) and an EADOGXL Display (SPI, 240x128, 4bit Grey).As of now i've only played with the 'baremetal' data and command to the display.I am wondering what the actual hw requirements for a custom board in touchgfx are.Is the DMA2D (ChromART) required?It says so in the Getting started with cubemx https://touchgfx.zendesk.com/hc/en-us/articles/360020001492-Getting-Started-with-CubeMX-and-TouchGFXI plan to use a single (or double) frambuffer in internal Memory, as it is a greyscale display with a not to high resolution it should be 240*128*4bit = 15kB of SRAM.Am I missing something else? Btw is there any full toturial on how to create your own target/board from scratch?Thanks in advance

Hi. I bought stm32f469i and Nucleo-h745 boards. H745 connects to STLink no problem. But the F469 discovery board doesn’t connect. I tried installing reinstalling drivers, connecting to other computer nothing worked. I couldn’t find another cable that I could try with so I ordered a new one it’s is going to arrive on Wednesday.Meanwhile is there anything else I can try?There are already questions similar to this one on the forum but nothing seems to help me. It is the third day for me messing with it. LCD powers up though. Red communication light keeps flashing slowly. any solution?

In version 1.1.0 the team group options is not ability of SVN. How can they be implemented?

Hallo everyone, I have an Olimex Dev Board with the STM32F407ZGT6 on it. I implemented the USB Middleware as VCP (Virtual COM Port) and it worked perfectly well on my windows 7 PC. Since I migrated to windows 10 I've been unable to connect to the VCP. NB: I have not modified my code. I will be thankful if someone could hint me on how to solve this problem. Thanks in advance.

Is there feature to scale images in TouchGFX designer? I don't mean scaleable image widget that will be rendered on the MCU, I mean that the Designer tool can scale image and pre-render them to new size. Then all the heavy lifting of scaling is done on PC.It is very useful to scale images in the Designer, for prototyping purposes, but use static image on the MCU for better performance. Otherwise I need to use image editor -> scale -> import -> repeat.Also, add "lock proportions when scaling" feature too.P.S. I love the tool! I evaluated 5-10 embedded GUI designers and TouchGFX is simply the best.

Hi,I'm trying to configure an I2C interface in SMBUS mode on an STM32F4. However, cubemx (v5.3.0) does not correctly generate code (missing include and file about HAL SMBUS, missing handle, empty init function, etc.). Compilation failed.Is there a plan to fix it?Thanks

I have STM32F303CCTX custom board.IO Pin PB8 has a timer that triggers a gpio high for 200us and resets for 300us. creates a 1.8KHz wave with about 35% duty using plain timer mode.

I feel uncomfortable with this: on page 26 AN5165 there are shown layers purposes. In particular, written, that INNER1 used as "grounding under the RF zones", but on images below (Figure 33) under RF this layer is deleted and as reference used another layer INNER2 (Figure 34). To check this I've downloaded Altium-project P-NUCLEO-WB55 and there actually INNER2 was as reference. Furthermore I find discrepancy of layers in Figure 24 and layer stack in projects. I've made some calculations: actually sizes of conductors and gaps correspond to the stack in the project, the p-NUCLEO-WB55 Board is executed correctly.
