Tool/software:
Hi,
we are using a customized board which is having tms320f28379d. we need to update the firmware using sci flash kernel. so, I have set the boot select pins GPIO72 & GPIO84 to 0 & 1 respectively. I am using SCIA for flashing (GPOI28-Rx, GPIO29-Tx). we changed the 0x0D00 to 0x815A for emulation test it is downloading the flash kernel to bootRom but main application is not downloading, Can anyone please help me with the correct and concise procedure to begin with. Do I need to make in special changes my code to achieve this? ,

// TITLE: Flash Programming Solution using SCI for F2837xD.
//
//! \addtogroup dual_example_list
//! <h1>Flash Programming Solution SCI for Single or Dual Core</h1>
//!
//! In this example, we set up a UART connection with a host using SCI, receive
//! commands for CPU1 to perform which then sends ACK, NAK, and status packets
//! back to the host after receiving and completing the tasks. This kernel has
//! the ability to program, verify, unlock, reset, run, and boot CPU2 to SCI
//! boot loader. Each command either expects no data from the command packet
//! or specific data relative to the command.
//!
//! In this example, we set up a UART connection with a host using SCI, receive
//! an application for CPU01 in -sci8 ascii format to run on the device and
//! program it into Flash.
