TM4C1294NCPDT: UART Bootloader

no i have not used the boot_demo_1 or 2, should i convert them to binary and try them

and yes i have configured the uart accordingly

okey i will try this out 

would this configuration be correct

I will suggest you NOT change the stack and buffer size yet. Use the default and get it to work first and then change these parameters later if you believe you need to customize these sizes. 

You should have the FLASH_PAGE_SIZE set to 0x4000 for correctness. 

#define FLASH_PAGE_SIZE         0x4000

thank you, after i have tried sending the boot_demo_2  it has worked correctly

then i changed the linker file for the blink_with_button project to this and that also worked
