HI sir,
we download the Led and UART code in to TM4C1294NCPDT launchpad that is working good. I added SSI code to led and uart code now I try to download the code in to launchpad using LM flash programer tool but it is not happens.
I am using LM flash programer tool to download the code.
please find the below link for video.
I used below code.
please find below code.
