Hi Allison, All the steps you mentioned works perfectly fine, and yes i am able to establish the SPI communication between external eeprom and controller, because in SPI_start_Boot() i can see it is reading the key : 0x08AA, which means spi is working and returning the entryAddress(Decimal :545171). But when i run resume after getting the entry address, it doesn't run the eeprom code, it still runs the controller code. Screenshots for your reference are as follows: 1)After completing the spi_boot() function which returns entryAddress, and i am going step by step till the exitBoot, and pressing resume, then code goes nowwhere(refer pic 4)): 1) 2) 3) 4) Best Regards, Saddam
