Hello,I have a SEPLOS brand battery management system card, and I want to read temperature and voltage data from this card. Initially, I will use an STM32F407VGT6 board to read data from the SEPLOS battery management system card via RS485. I am sendi...
Using stm32f767zi microcontroller and sd interfaced with spi and interfacing usb_host_msc code below tutorial following its working only when i sperately using but interface with sd card with pi below issue is getting https://embetronicx.com/tutorial...
Within USBH_MSC_Write() the USBH_MSC_RdWrProcess(phost, lun) loops. Loop runs into the 10s timeout (see screenshot). USBH_MSC_RdWrProcess(phost, lun) still returns BUSY for this 10s period. Status:MSC_Handle->unit[lun].state is MSC_WRITE MSC_Handle-...
Hello Community,I am encountering an error after my STM32H7ZIT6 device runs for a few hours. The device is intended to send and receive data from AWS. The error logs show repeated instances of mbedtls_ssl_read_record() returned -27648 (-0x6c00), ulti...
There are some older posts on the net about how to achieve a reboot in DFU mode but none of them worked for me. So I want to share my solution on how to add this functionality to your embedded firmware. First off all, I am using CUBEIDE with a STM32F...
hello all, when I use HAL_FLASHEx_Erase() to erase sectors, it is ok! But when I use HAL_FLASHEx_Erase_IT() interrupt mode to erase sectors, it fails! It seems the interrupt not occuring! if I need to do more settings for flash in...
Is there any way at all in PC software (Either the ST libraries or things like libUSB) to identify whether a device in DFU/Bootloader mode is an F407 or F411? Everything I can find in the USB properties is identical between the two (Same VID/PID, sam...
Hello I'm migrating my STM32F072 project to the STM32L072.In my original project (F072) I can jump to the DFU bootloader by software via a function located before SystemInit.I tried to convert this to be used by L072 by changing the address of bootlo...
Hello everyone, I am using an STM32 microcontroller and I am facing a problem when I try to mount an external flash memory. The problem is inside the function lfs_dir_fetch which is returning unexpected values in the test buffer here: struct lfs_dis...
I'm trying to achieve a UDP communication with STM32H753IIT6 and LAN8720A.I use STM32CubeIDE 1.14.0.According to the ST Ethernet and LwIP example: Adam BERLINGER edited on 2023-12-07 , I create a project, and change the pin layout according to my...
