I added nand flash to stm32mp157aac, but the nand startup mode is always DFU mode, may I ask what configuration is needed?Nand boot has been selected on the hardware

Hello,I am fairly new to the TouchGFX designer and am trying to build an application where I can copy the contents typed using the keyboard on a screen(Custom Keyboard application provided with the designer) to another TextArea . I would really appreciate any help regarding this problem.

I am interfacing (IS66/67WV51216EBLL) 8Mbit static RAM organized as 512K words by 16 bits with STM32F723 microcontroller using it’s inbuilt FMC interface. FMC is configured in 16bit mode. Read and write operations are working as expected. But I have some confusion related to addressing memory as:      1.     As PSRAM is having only 19 (A18-A0) address lines which means that 512K addresses can accessed, which is true for 16_bit address pointer and I am able to read/write whole memory (1Mbyte) which means one physical address points to 16 bit data.2.     Confusion comes when I access memory using 8_bit pointer in which I am able to address memory above 512K address(up to 1023K last address accessed).Which is not possible for PSRAM as there are only 19 address lines.3.     I also know that FMC is able to access 16Bit memory byte wise using UB# (upper byte control) and LB# (lower

Hi,I've been trying to setup a cross compile environment using Docker for Windows, and I've run into a bit of trouble. I've setup the dockerfile so that during the build process of the image, I copy the SDK into the image and execute the .sh script.This is step 4 in the getting started section of the wiki, under "Develop on Arm Cortex-A7"/"Install the SDK":https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157C-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Install_the_SDKThe problem:Executing the SDK installation script does not work due to the following error:ST OpenSTLinux - Weston - (A Yocto Project Based Distro) SDK installer version 2.6-openstlinux-4.19-thud-mp1-19-02-20 ===================================================================================================================== You are about to install the SDK to "/STM32MPU_workspace/STM32MP15-Ecosystem-v1.0.0/Developer-Package/SDK".

Hi,I'm currently playing with the X-NUCLEO-GNSS1A1 kit and I have two questions:-If I only configure Galileo the messages are still GPGLL and I do not get GAGLL for Galileo and I do not know why?-The Teseo Suite allows you to filter messages eg xxGLL, but can you directly configure the module to limit the type of message sent by usart?Thank you,Pierre

I am working on a custom board with TouchGFX, and the custom board connects to a SPI LCD. I found an issue that TouchGFX will call flushFrameBuffer(const touchgfx::Rect& rect) function twice when making a screen transition. I just wondering if the behavior is normal, and why.Best Regards!

Hello,I am reading a sensor on m4 side. And debugging in production mode for the target.I have called printf function in main.c but I cant see anything when I run the program.Is it normal that I cant see any console while the program running ?

Posted on March 29, 2017 at 00:21I've been working with USB on my Nucleo board(S)  for some time now. Been comfortably successful at getting a few operational interfaces working with it. Including DFU. STM32L476. So time to make our own PCBS! We knocked out an order for 10 . Production needing 7 and having a few SPARES to help wear off the new. Ran into a little problem and I turned in an online help request. Waited all day and thought maybe someone there might notice I marked it Critical. Not sure of the turnaround time but everybody's critical  might be a little different. Hope I hear and in the mean time here's where I got too.We have 10 Brand new (Identical) PCB's with STM32L476VG's on them.They use the direct connected USB for communication. (PA11/PA12)They are *all* loaded with the same binary, VIA DFU.DFU works. Dependably.The binary is the STM32CubleL4 HAL DEMO from EVAL board, with IO EXPANDER commented out. This runs the LEDS on EVAL and is the only thing

I have a new project on an STM32H743 and thought it is a good idea to start this one with the latest version of CubeMX (5.3.0.) and the latest HAL library (1.5.).As I already have several systems running with USB VCP (STM32F746 and STM32H743) which were created with older releases of the Cube/HAL, I applied the necessary changes to the USB routines and thought it should work like in the old projects.But I get failures on the PC side "The device cannot start (Code 10)" when attaching the new system. Some rare times it works, but most times I get errors. I already increase Stack and Heap size to 2000. So this should not be the reason. Hardware should be ok as this also has been done like on the other systems.Has anybody an idea what I should have a look at? I use a Win10 - 64Bit PC and the driver version of the VCP is automatically installed (V. 1.4.0). My other systems are performing USB VCP without issues on that PC.Any comments very much appreciated!

I have configured my ADC to convert an analog value every 100 milli seconds using timer 2 , I could able to write data to EEPROM but while reading it back i could only see 20 variables in array. As below mentioned in code, I could able to switch on my LED .But my question is why I could not able to display/read all the 50 variables in my array in my watch windows of keil MDK? However, i can only read till 20 variables (data_read[20])! what could be the possible reasons?? I couldnt able to comprehend. is it because of the capabilities of Keil / ST link V2 debugging or because of the functions i am using to read EEPROM. As per the below code and output i.e, I could set( switch on My led) I am with a hypothesis that, data is written into EEPROM , I am only facing problem of reading all the 50 variables in array because of debugging capabilities of software and hardware ? Am I correct or wrong? Could some one please validate? code ( I have kept only the essential lines): uint8_t data_read[

Hi,I have just started a new app using SDK 1.5.0. The problem I am seeing also is present in V1.4.0.We are using an ST25DV04K tag, and on phone scanning a tag we get through to line 192 TagDiscovery.java:try { switch (tagInfo.productID) { case PRODUCT_ST_ST25DV64K_I: case PRODUCT_ST_ST25DV64K_J: case PRODUCT_ST_ST25DV16K_I: case PRODUCT_ST_ST25DV16K_J: case PRODUCT_ST_ST25DV04K_I: case PRODUCT_ST_ST25DV04K_J: tagInfo.nfcTag = new ST25DVTag(readerInterface, uid); break;Stepping into ST25DVTag. However, as we descend into the libraries, we eventually get here:public STRegisterField(String name, String description, int mask) { this.mName = name; this.mDescription = description; this.mMask = mask; this.mBitField = new BitField(mask); this.getBitStartEnd(); }But there is an eventual crash in STRegister.java, line 5 (this.mBitField = new BitField(mask).Stack trace:java.lang.RuntimeException: An error occurred while executing doInBackground()      &nbsp

I am trying to periodically wakeup STM32L010K8 from standby mode. The project is generated is using CubeMX. The device doesn't wakeup unless I reinitialize RTC everytime it resumes from standby. How can I avoid reinitialization of RTC everytime?/* 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 * License.

Currently TouchGFX generates code (my target is a STM32F469 DISCOVERY board) that is based on the ST CubeMX framework. Is the 'mbed' framework on the roadmap, since I like it *a lot* better.

I want to know how to switch ST25R3911B from reader/writer mode to the P2P mode? Are there any register to config the working mode? In the datasheet, I find there is a register called "Operation control register" which can control the rx and tx enable. Is this register control the operating mode?

Hi,Greetings of the day,Here I am searching the BlueNRG-2 in the stm32cubemx. But I am unable to found out that. Please help me Regards,

Hello,I am reimplementing the example application OpenAMP_TTY_echo in STM32MP157C-DK2.I want to exchange numerical data between M4 and dual A7. How can I do it ? which structure, channel or interface ?thanks in advance

Posted on April 05, 2017 at 12:48HelloI'm trying to read data from a GPS module that send packets with different lengths. I connected the rx line to another pin and enabled an interrupt on it, in this way I can 'timeout' the end of packet (packets are one per second, plenty of time between a pair).I set-up DMA on UART (tried both circular and normal) because I don't need UART interrupt to read data. I would like to read data on timeout, but after the read I need to reset the state of DMA in order to empty the buffer and restart writing from index 0. I need to know the dat tranfered too.I'm using an STM32F101 device with HAL library version 1.4.0.No luck with examples from ST nor documentation around internet.Thanks for your help.Sergio

Hi again @Martin KJELDSEN​ !I have a textarea with one wildcard with a fix width but ajustable height. If the wildcard doesn't fit I would like to have the text split in multiple lines, and/or change the text size to be smaller. Is there a simple function/setting to use for that or do I have to manually check getTextWidth()?Thanks in advance for the help!

In the sample code, STM uses "HAL_GPIO_EXTI_Callback" to handle interrupt from a push button, but in class I learnt that we need to use the IRQHandler to handle the interrupt. When to use "HAL_GPIO_EXTI_Callback" and "HAL_GPIO_EXTI_IRQHandler" to handle interrupt?

Hi I use GT9147 touch IC on my stm32mp157 board. I found the stm32mp157c-ev1.dts use same chip. But the ev1 use GPIO14 of stmfx GPIO expander chip as TP_INT signal. The GPIO14 of stmfx configure as below code.486 hog_pins: hog { 487 pins = "gpio14"; 488 drive-push-pull; 489 bias-pull-down; 490 };Now, my board use PG7 as TP_INT signal. I also want to configure the pull-down property to PG7.Below is my touch panel code. gt9147@5d { compatible = "goodix,gt9147"; reg = <0x5d>; irq-gpios = <&gpiog 7 GPIO_ACTIVE_HIGH>; irq-flags = <IRQ_TYPE_EDGE_RISING>; reset-gpios = <&gpiog 8 GPIO_ACTIVE_HIGH>; status = "okay"; };So, my question is how to configure pull-down property of irq-gpio. I try to add "pinctrl-names" and "pinctrl-0" property to gt9147 section, but kernel shows pinctrl errors. In my opinion, other SoC platform support "hog" to config each gpio pins. Does the gpiog or pinctrl suppor this function in stm32mp1 platform?

Hi,Is there somebody who really used the RTC using external crystal (HSE) of 32.768KHz ? I tried to use it but with no success.Using the RTC with internal oscillator of 40KHz (HSI) the all it's OK. I think that there is a problem with external crystal for this micro. It's possible?
