non- functioning peripherals

[amirshn]

Hello everyone,

I have recently started working on a custom board which has a STM32H733VG as the MCU. various interfaces including UART, I2C, SPI and sdmmc has been implementde 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-link debugger and eveyhting seems fine expect this part while i am trying to debug:

So i was wondering is there any connection between my peripherals function issue and these memory verification issues?

In case of software implementation, I am 99% sure that i have done it right.

I have also attached my MX CUBE configuration file and my "main.c" file while i have tried to configure the interfaces.

Any help or hint would be highly appreciated.
