Solved

I found some bugs in the CubeMX generated code.Does it forget reset the `state` after SDIO DMA TX? when I query the TX state by `HAL_SD_GetState` always get wrong result. Dose SDIO DMA mode forget clear the transition state to SD card? when erase the block after a DMA read, it always failed, I have to put a `HAL_SD_Abort` after RX finished. The follow code blocks forget `__DSB` sync instruction in function `HAL_NAND_Read_Status`, My MCU is stm32f746ig which with data cache, the origin version of code makes the MCU infinite loop.

The description for HAL_GetTickFreq says/** * @brief Return tick frequency. * @retval tick period in Hz */It returns 1 when the tick frequency is 1kHz. The period would be .001 seconds and the frequency would be 1000 Hz. Based on the typedef below, I'm not even sure what the units really are, but the description is clearly wrong.typedef enum{ HAL_TICK_FREQ_10HZ     = 100U, HAL_TICK_FREQ_100HZ    = 10U, HAL_TICK_FREQ_1KHZ     = 1U, HAL_TICK_FREQ_DEFAULT   = HAL_TICK_FREQ_1KHZ} HAL_TickFreqTypeDef;

I have STM32F407VG board and it has error in flashing time see screen. I have STM32F407VG board, and it has error in flashing time see screen. Yesterday was everything ok but today is broken, I don't know why!I found a solution https://community.st.com/s/question/0D53W00000V0NbvSAF/got-error-like-stlink-error-devtargetnothalted-when-to-flash-the-program but my board doesn't have a pin "VDD", see screen.And second, misunderstanding what is mean "(hope you are using boot selection through Boot 0)."?

When creating a new project in the STM32CubeIDE for a STM32F103C8 (64k flash, 20k ram), the generated linker-script contains:/* Highest address of the user mode stack */ _estack = ORIGIN(RAM) + (LENGTH(RAM) / 2); /* end of "RAM" Ram type memory */   _Min_Heap_Size = 0x200; /* required amount of heap */ _Min_Stack_Size = 0x400; /* required amount of stack */   /* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 20K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 64K }This places the stack (_estack) at 0x20005000 = 0x20000000 + 20k. When checking the memory at (_estack - 1) via the debugger, it can't be read. So while startup the STM32 immediately goes into a hard fault.In fact, the last readable address is 0x200027ff, which suggests, that the address is actually in words rather than bytes : 0x20000000 + 10k = 0x20002800.Changing the line to_estack = ORIGIN(RAM) + (LENGTH(RAM) / 2); /* end of "RAM" Ram type memory */places the stack at 0x20002800 and fixes

Could someone to give a link to an "Linker Code" about which is mentioned in paragraph 12 in this tutorial https://community.st.com/s/article/how-to-add-your-spi-flash-into-the-stm32cubeprogrammer-external-loader-part1

Hello,I'd like to learn more and understand how to create project that will work with code in internal and (or only in) external Flash ?Examples in CubeH7 seems to be set to address of external Flash memory.Thanks in advance,regards.

I need help in implementing a solution. I'd like to implement a system that measures elapsed time (ET) between two digital input (DI) pulses. These two signals will be on different channels. There are 4 sets of signal, therefore I need to measure four things: ET(0) = DI(0) -> DI(1), ET(1) = DI(2) -> DI(3), ET(2) = DI(4) -> DI(5), ET(4) = DI(6) -> DI(7).The counting should be between positive edges, resolution should be in microseconds, maximum time will be <= 2s. Each of the measurements should reset on DI(x) and store on DI(x+1). It is possible that multiple DI(x) will occur before DI(x+1) therefore ET will always be the measurement between DI(x+1) and the last DI(X)I first implemented a solution with a raspberry pi pico. That solution implemented an interrupt on each of the digital input channels that triggered on a positive transition. The interrupt handler essentially queues up the DI index and a 64bit microsecond tick count on a pre initialized queue. The super loop

i had USB Host MSC working on H743 (devE board) , read USB sticks 1...64 GB without problem;now, after try to make USB Audio Host on second (HS) usb port, which is not running until now (there is no working example by STM - and no plan to do this (!) ) , access to usb stick no more working; and i have no idea, why ...or what i did wrong.i installed SWV , to see more info, this is coming, when debug level on usb is set :obviously usb stick is enumerated, can read size and directory, but when read data (16KB) it hang up in some usb BOT loop or USB_busy state. anybody knows, what i should do now, to get it running again?+ maybe , howto get audio host running?

Hi,today i got a STM32G0316-DISCO and totally forgot to setup serialwire. All Pins except PIN6 where configured as GPIO-Output. No i can't connect to the MCU. I tried most of the hints regarding "connect under reset" but no success. I had also one try with my J-Link, but no success. Is it possible to use JTAG to get it back working?thanksPeter

Hello, I have a spare STM32F427ZI MCU. Can I replace F429ZI with F427ZI? Please suggest some other possible replacements for F429ZI.

I am using the STM32L4S9AII6 clocked at 120MHz. This device is being used as a slave to a master that is clocked at a much higher frequency. They communicate over the SPI1 bus. I am trying to optimize the rate of communication between these two devices. How do I validate that the SPI transmit API call has TX data sent to the SPI peripheral and is ready for master get it? I need to set a flag (GPO pin) to the master when the slave has finished processing a command and is ready for another command. When I try to set this "finished processing" flag immediately after the HAL_SPI_TransmitReceive_IT() API call the master sends the next command and attempts to retrieve requested data from the last command simultaneously. However, most often the slave misses the deadline and the data that was intended to be sent to the master doesn't show up until the next command cycle. Obviously the MCU is not able to get the data to the SPI peripheral fast enough before the master comes asking for this data

Most of the target status seem to return 5 but some do return 255.The data is correct on all 64pixels when I have a near object (200mm) but it cannot detect further objects like the ceiling and instead it will return a seemingly random small distance that keeps constant and fluctuates a bit arboud its value.I'm on the esp32 with other I2C devices on the bus.Thanks in advanceEdit: It does not seem to be working for distances over 255mmLucoreds

Hi all, I'm new to this STM32 community.I have a small problem: I bought some STM32G0P0.. for my project, also making the PCB and the rest. But after soldering the various components, I try to program one and see that the level 2 protection is active, I try to program another and there is the same thing.What I see from the STM32 St-LINK program is that only some memory pages have protection, while others don't, but then going to view the memory areas I see that they have all been set to FFFFFFFF.Below I can see that the memory on the address 0x08001400 is free, but..  ..here I see that is protected! How can I program it? My question now is: what the hell do I do? Do I ask for a return? Is this a normal thing of STM32G0...? Trying to write a bootloader that makes me jump from one address to another when the memory to read is full?Thank you for your availability and attention

The STLINK-V3SET Suggest the following connector for one of the three cables included with it: Samtec ASP-203799-02. However, I cannot find this connector on Samtec or any corner of the internet other than the STLINK User manual. Where do you get this connector?I see others have asked this question without a response. I can't post a l*nk to this topic as I'm a "new" member so here is a hint to the message:" d " = ."

I know TouchGFX Designer GUI is a Windows only app, but is there any way to only run the generator tool (tgfx.exe) to generate all files of a .touchgfx project on a linux machine via command line?

I'm trying to use STM32F730 for MODBUS communication. The datasheet and reference manual both shows support for MODBUS. However the problem is :when i use cubemx for configuration purpose it generated following message "This peripheral has no parameters to be configured".Further i generated the code when i check code using IDE the USART initilization function has no code and it appears as follows:static void MX_USART1_Init(void){ /* USER CODE BEGIN USART1_Init 0 */ /* USER CODE END USART1_Init 0 */ /* USER CODE BEGIN USART1_Init 1 */ /* USER CODE END USART1_Init 1 */ /* USER CODE BEGIN USART1_Init 2 */ /* USER CODE END USART1_Init 2 */}As per my understanding this initialization function is not correct.So all of you are requested to help me to understand what is the issue.Regards

Hello,I am looking to implement BLE MESH onto the WB10, however there are not any tutorials. I usually import the NUCLEO-WB15 onto the WB10 as they are similar bar a few config values but there aren't any WB15 MESH examples either, just the WB55. Has anyone got a BLE MESH example for the WB15 or WB10?

Hello,I recently purchased STM's BLE nucleo expansion board, which works without issue. I am reviewing the software to develop my understanding and had a question regarding the MAC address. They are typically a unique address to the specific chip that is used and that every manufactured piece had a different MAC address. However, for the sample code (SensorDemoBLE), I never had to put in the IDB05A2's BLE MAC address. It knew, which means that every IDB05A2 must have the same MAC address. Judging by this, is this assumption about the MAC address being unique wrong? In other words, if I ordered another Bluetooth BlueNRG-M0A chip, would it also have the same MAC address as the sample code?

Hi team, I have been asked to work on STM32WLE5JC development kit. So, I have purchased one kit online. Meanwhile, I would like to know which IDE (for coding) is best to work with the kit as well as the other necessary hardware and software tool chain suitable for my purpose.Thanks.

I'm looking for prototyping daughterboards for the STM32H757I-Eval boards. Is that something that is readily available or are we on our own for building those?If I need to build my own boards, what is the best connectors for those male pins located on the board? They seem like a tight pitch and isn't something I'm familiar with.

Hi, I have STM32F4 and I am trying to send list of messages in order with CAN BUS:// CAN BUS message data list in particular order // 01FFFFFFFFFFFFFF // 02FFFFFFFFFFFFFF // 03FFFFFFFFFFFFFF // 04FFFFFFFFFFFFFFI have AutoRetransmission enabled, because sometimes it fails to transmit message. hcan1.Init.AutoRetransmission = ENABLE;The issue I am observing is that message list does not arrive in the same order:// CAN BUS message data list received in bad order // 01FFFFFFFFFFFFFF // 04FFFFFFFFFFFFFF // <-- bad order // 02FFFFFFFFFFFFFF // 03FFFFFFFFFFFFFFIs this a bug? How do I keep messages in same order which I want to send?
