Target Software Startup Script Error

[Utkarash Patil]

Hello All,

I am using STM32F777IITx MCU based custom board with STM32CubeMx v4.24.

I want to built a application where i want to Read/Write data from/to flash.

I am have written a small application where i write 10 bytes of data to flash and also read those 10 bytes from flash

My code Complies properly with no errors, However, when i tried to run the code in Debug mode i am getting the error mentioned below.

Whereas i have not changed anything in the Startup script, also i have attached the startup script below

# Set flash parallelism mode to 32, 16, or 8 bit when using STM32 F2/F4 microcontrollers
# 2=32 bit, 1=16 bit and 0=8 bit parallelism mode
monitor flash set_parallelism_mode 2
 
# Load the program executable
load		
 
# Enable Debug connection in low power modes (DBGMCU->CR)
set *0xE0042004 = (*0xE0042004) | 0x7
# Set a breakpoint at main().
tbreak main
 
# Run to the breakpoint.
continue

So please help me to get rid of this issue at the earliest and if i am making any mistake while debugging please help me with it ,

Also if there are changes to be made in startup script please help me with correct startup script

Thanks and Regards

It looks like some error occurs in the "load" command.

Please open the Debugger console window and see what it says there.

(the output should begin with "STMicroelectronics ST-LINK GDB server" .... )
