I see the on-line tutotrial-style documentation. I see the doxygen-generated details. Is there any documentation that describes how it actually works? What is the architecture? What calls what? What are the operations inside the binary library?The real challenge, for me, is making a GUI-centric design model work in an electro-mechanical control system. The GUI is then ancillary to the important operations of the system. The business logic needs to be outside the GUI code. The documentation I've found doesn't show how drive the GUI externally. The "interactions" are 99% outside of the GUI.

Hi everyone,Can I assign, for example, UART to Cortex M4 runtime context, and generate appropriate device tree files for STM32MP1, and then after boot, reassign UART to Cortex A7 runtime context somehow? Best regards, Nenad

Hi,the meaning of the PLS[2:0] bits in the PWR_CR2 register is not yet documented in the RM0440 Rev2, they're marked "TBD" (see screenshot attached). Could you provide the mapping of thresholds levels?Thanks a lot!Regards,Matthias

I've designed a board with stm32G431 MCU (i will include schematic if necessary) and now trying to test how it works. I am using CMSIS for programming and wrote the most simple blink program (LEDs are on PB3-6):#include "stm32g431xx.h"   void delay(uint32_t time);   uint32_t someVar = 0;   int main(void) {   RCC->AHB2ENR |= RCC_AHB2ENR_GPIOBEN;   GPIOB->MODER &= ~0x00003FC0; GPIOB->MODER |= 0x0001540; GPIOB->ODR |= 0x0078;   while ( 1 ) { delay(300000); GPIOB->ODR ^= 0x0078;   someVar += 1;   } }   void delay(uint32_t time) { for ( uint32_t i = 0; i < time; ++i ); }And when I debug it. It works just fine, but after I hit reset it doesn't work anymore. I checked with st-link utility. The program is still in flash. Can anyone explain what is going on and how to fix it?

Hi.Is it possible to re-use some of the screens of previously developed TouchGFX project ?I have tried the option of importing the GUI but it overwrites my current project.Please share your thoughts or suggestions.Regards,Shree

I'm trying to enable the OB_RDP_Level_1 for a STM32L151CC but It fails. The MCU becomes bricked. I can't even boot to DFU. I need to first start ST link utility and set read out protection level 0, and then do a chip erase. But I noticed that bit OPTVERR = 1 indicating that the option bytes are faulty. I have tried a fulle chip erase and it does not set the OPTVERR to zero. Is it possible that I have a special STM32 that always start up with OPTVERR = 1? I have tested on some evaluation boards and they have OPTVERR = 0 at start.

I found out today that my project was not properly configured. So i did run out of flash memory.By comparing with a Designer project I found out how to change the FLASH.ld file to use QuadSPI and some other things that were different in the Designer project regarding QuadSPI.But my program crashes again and again in the function void touchgfx::Texts::setLanguage(touchgfx::LanguageId id).Is there something like a tutorial on how to configure TouchGFX + QuadSPI in CubeIDE?Regards,Kevin

In my project, which uses FatFs and a couple of peripherals, I always used a heap size of 0x100 bytes, with no apparent problems.After activating the USB Host for HID Class, I increased the heap size to 0x2000 bytes (8 KB), but still the USBH_malloc call for 52 bytes in USBH_HID_InterfaceInit() fails, i.e., returns NULL.USBH_malloc seems defined as plain malloc, but alas, I cannot debug into the malloc function.The heap section in the linker file is_Min_Heap_Size = 0x2000; /* required amount of heap */ ... /* User_heap_stack section, used to check that there is enough "RAM" Ram type memory left */ ._user_heap_stack : { . = ALIGN(8); PROVIDE ( end = . ); PROVIDE ( _end = . ); . = . + _Min_Heap_Size; . = ALIGN(8); } >RAMat the end of the declarations. The map file shows the position of the heap as intended:... 0x0000000020019848 __bss_end__ = _ebss   ._user_heap_stack 0x0000000020019848 0x2000 load address 0x0000000000217308 0x0000000020019848 . = ALIGN (0x8) 0x000000

Greetings embed ProfessionalsRecently taken onto STM32 and getting along quite well so far! Regretting for not having done so earlier so plenty of catch up and "learning to do" (ps. mechanical engineering background here). Learning in particular; I'd like to investigate how professionals would go about implementing an optimized data bus for lower end mcu (e.g. STM32F1x/budget limitations). Below is what I have coded so far, which works great btw, however I feel the performance is quite lacking, something, somewhere.Is there any other way(s) I could get 16-bit across faster???ps. The #define DATAOUT(i) seems to be the bottleneck Thanks for any recomendation/alternative ways you may have, I'd sincerely appreciate a hand//LCD.H #define DATAOUT(i) { \ GPIOA->BSRR = 0b0001000011111111 << 16; \ GPIOA->BSRR = (((i) & (1<<0)) << 0) \ | (((i) & (1<<1)) << 0) \ | (((i) & (1<<2)) << 0) \ | (((i) & (1<<3)) << 0

Hi,I have a NUCLEO L552 and I would like to run a very simple program (just blinking a led).I have placed my vector table @ 0x08040000 as described by the data sheet. to program the flash I use the J-Link from Segger. What is strange, is that I cannot execute my program. Now, if I use Ozone from Segger, I can execute it, but when I power off-on the target, the program does not run anymore; again, Ozone can execute it. Probably, Ozone disables some protections ... any idea of what I have to add to my code to run in a non secure mode and make my code always executable?

Hi,I'm trying to utilise the built-in UART bootloader in the STM32F031K6 to perform firmware update. I've read the AN3155 and AN2606 documentation but unfortunately, I'm out of luck so far when trying to write the firmware via the bootloader to the target MCU's internal flash.What I've got working so far:I can communicate successfully over the UART interface to the bootloaderThe GET command response indicates the bootloader protocol version is 3.1 and the following commands are supported:0x01 (Get Version & Read Protection Status)0x02 (Get ID)0x31 (Write Memory)0x73 (Write Unprotect)0x92 (Readout Unprotect)The GET ID command response indicates the PID is 0x401The following is not working for me:I send the "write memory" command and checksum, e.g. 0x31, 0xCEI receive the ACK, e.g. 0x79I send the 4 byte start address and checksum, e.g. 0x08, 0x00, 0x00, 0x00, 0x08I expected to receive either an ACK or a NACK but no response from the bootloaderSome observations:Immediately following t

I have the STM32F769I-DISCO board and just made a simple application that uses usart1 to print some debug messages on the virtual com port (USART1. Everything works fine until I power off the board. When the board is connected to usb cable again the ST-Link utility or the CubeIDE debugger can't connect to the board. This is a message from the ST-Link utility.It goes well to bring the board back to life by setting BOOT0 pin high on start and erasing the flash. But this is annoying to do it every time and also this is not how it should work.I just started working with STM MCUs and will appreciate any hints in which direction to look for the root cause of this behavior. Best Regards,Anton

Hello everyone,I managed to build st-example-image-qt on my STM32MP157C-DK2 with some extra image features.Now i just want to run bitbake meta-toolchain-qt5 but the build end up with errors that i can't solve.I attached the output console when i try to build it. Do you have any clue how to resolve this ?Thank you.

Hi everybody! I've been struggling with this monster for a few days now. I'm trying to make it do some very basic (pun not intended) things and I have little hair left... But let's cut a (too) long story short: I'd like to send with the SPI a few bytes to a device. I'm using polling (DMA and INT's is an epic drama for another time), although that's not relevant at this point. So let's just send a byte (8 bits) thru SPI. I've set up the GPIOs for the SPI normal, as alternate functions (most of this code has been generated by CubeMX) - with NSS port as normal output - like this:LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_GPIOA); LL_GPIO_InitTypeDef GPIO_InitStruct = {0}; LL_SPI_InitTypeDef SPI_InitStruct = {0};   GPIO_InitStruct.Pin = CK_Pin; GPIO_InitStruct.Mode = LL_GPIO_MODE_ALTERNATE; GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_HIGH; GPIO_InitStruct.OutputType = LL_GPIO_OUTPUT_PUSHPULL; GPIO_InitStruct.Pull = LL_GPIO_PULL_DOWN; GPIO_InitStruct.Alternate = LL_GPIO_AF_5; LL_GPIO_I

Hi,I want to generate a new distro for MP1 with distribution package and qt-examples. I downloaded all of the packages via fetchall command to avoid getting an internet connection error during generating. After that, I have tried to generate an image including qt examles. However, it wasn't completed for 2 days(it didn't compile qtwebkit for 2 days). I then have cleaned qtwebkit with "bitbake -c clean qtwebkit" command and tried compile only it(bitbake qtwebkit) but get an error is error 1 again. Why does it compile? And, how can I disable it from the image?

We have a current device that utilizes the st25r3911b and the stollmann stack.Now that the Stollmann NFC protocol stack is no longer, is there a stack that can replace it in Android in the the ST world and the ST25R3916 or is NXP the only NFC solution for Android? I'm a hardware engineer on theproject.Thanks for reading,Don

I like the way CubeIDE generate the code. Especially with "Generate peripheral initialization as a pair of '.c/.h' files per peripheral". This is very helpful tools not only for start the project but also for checking particular functionality.Why examples delivered by STM are not in exactly this shape?It will be very comfortable to compare our code with STM's examples code.It will be also welcome to see the examples code with "Generate peripheral initialization as a pair of '.c/.h' files per peripheral" option. The code is more clean. Please consider use this option at least for Low Layer examples.

MCU: STM32F030CCT6Programmer: ST-Link/V2Software: STM32 ST-LINK Utility v4.1.0.0I'm new to STM32 mcu's and trying to comprehend the memory map.The Reference manual (RM0091, DocID018940 Rev 9) states in section 2.5 that when the Boot0 (pin) is high and the nBoot1 (bit) is high, the System memory is aliased to the boot area 0x0000 0000.And when the Boot0 (pin) is low, the Main Flash Memory is aliased to the boot area.To get more comfortable with working with ST-LINK Utility and test my understanding of the memory map I tought it would be a good excersise to verify this.So using the STM32 ST-Link Utility I compare 3KB of Main Flash memory with the boot area while Boot0 (pin) is low.And yes, the memory content between boundaries0x0000 0000 - 0x0000 0C00is idential to0x0800 0000 - 0x0800 0C00This is as expected.Now I reboot the system while holding the Boot0 pin high (and nBoot1  bit is also high), thus I expect the System Memory content at the boot area.But the memory content bet
