Hi, I'am trying to connect two STM32H7 boards with ethernet protocol, I want to exchange some UDP messages, I implemented code for udp protocol but it still not working. Is there any example of two boards connection through ETH lwip .Thanks for help

FATFS + FreeRTOS memory corruption, need confirmation

Hi,I created a project using the STM32CubeIDE for a STM32F2xx. This project include USB in host mode with a mass storage class, FATFS and FreeRTOS.With freeRTOS, FATFS is put in REETRANT mode. I also put the MAX_SS to 4096 because I need the sector s...

Example "I2C_EEPROM_fast_mode_plus" does not seem to work

Hello ST Team,I'm currently studiing how to manage the I2C communication on the STM32H743-EVAL2. To do so, I used the STM32CubeIDE to find an example to see how it shall work properly and I downloaded the code of "I2C_EEPROM_fast_mode_plus", which wa...

STM32H7 and calloc failure

Hi,I am using a STMH743 running an LWIP example, added in mbedTLS to the mix.Eventually, got into a certificate parse issue,narrowing it down:I found that calloc failed: (890) x509_crt_parse_der_core: (899) x509_crt_parse_der_core: mbedtls_calloc(), ...

Can I use the STM32F303RDTx's ROM bootloader with level 1 flash readout protection?

ST provides a ROM bootloader in the STM32F303RDTx. I am able to jump into the bootloader from my application, and update the flash when read out protection (RDP) is disabled (level 0). When RDP is set to level 1, all attempts to disable RDP (which ma...

Is there any solution to jump to application from the internal bootloader with BOOT0 pin connected to VDD

I'm using STSPIN32F0A witch is based on STM32F031C6 MCU and in my case BOOT0 pin is always connected to the VDD to force the board to boot on system memory, and the idea is to jump from the bootloader to the application on the main flash using the bo...

Bug in stm32f3xx_hal_i2c.c

CubeIDE version 1.4.1STM32Cube FW_F3 V1.11.0I had the problem, that my I2C communication (alternating rx/tx on slave) works on the first rx/tx cycle but fails on the second tx.The transmission skips the first byte and thus sending n-1 bytes. I found ...
