Hi, I'm using an STM32L4R9 on a custom board with USB.The project has the Host Only and Device Only implementations of the CDC Device and a MSC Host stacks.As we don't have a USB-ID pin, we can't really use the normal OTG behaviour, so the project is...
Hi,I recently created a custom board based on STM32G030 IC and programmed it via UART to run my application. Now, I want to make some changes to my firmware, but I can not connect to the CubeProgrammer. I have tried connecting it via UART and ST-LINK...
Hello everyone, the STL_programmer currently calculates the CRC only for the in-use memory or up to the binary file size. Is there a way to fill the remaining flash memory with zeros and calculate the CRC for the entire flash area, eliminating the ne...
Hi, I am trying to create a connection through ethernet with lwip however I stuck at netif down I guess it related with flags which are checking the connection. I am using STM32H735 board. lwip.c file codes are taken from the github (https://github....
CONTEXT:I have been working with an STM32F429ZI Nucleo, trying to connect a USB thumb drive, to update the user application firmware. I have started with the MSC_Standalone project as it exists as an example for the F429ZI and I have been integrating...
I'm trying to implement a USB touchscreen on a NUCLEO F446ZE. I'm making a full-speed device using ST's USB library (Custom HID class) and I'm testing it with on a Windows 10 host. The first contact registers, but when I try to press another, it doe...
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...
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...
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...
I am starting a personal project where I will be designing custom hardware and software for a device that would be be similar to a smartphone. I want it to be able to connect bluetooth, wifi, have speakers and use USB-C(power, data transfer, etc.). I...
