Hello everyone,
I have recently started working on a custom board which has a STM32H733VG as the MCU (STM cube IDE and CUBE MX as the development environment).Various interfaces including UART, I2C, SPI and sdmmc has been implemented hardware wise to provide links between MCU and other chips on the board. I was able to write to an SD card however when i want to read or right from other chips (external RTC (ISL12057), GPS module(MAX-M10M), ...) using I2C or UART interfaces, i get nothing. I am using SEGGER J-trace pro debugger and here is its console log:

due to some unknown reason, it tries to check some reserved part of memory and it fails on their verification. Its almost a week, i have tries multiple solution found in different forum and still no luck.
Any help or hint would be highly appreciated.
Truly yours,
Amir
