Introduction

Note

This is NOT a bootloader but a helper application running on a host board, that sends the bootloader and application image to the target board.

This application can be run as we run any other applcation using any boot modes preferred. This application works in conjunction with SBL PCIE. The application sends the images required for the target board to boot from PCIe boot mode. The application first finds the SBL image by name sbl_pcie.release.hs_fs.tiimage from the SD card and sends the image via PCIe for ROM to boot.

Then the appimage is send via PCIe for the SBL in target board to pick up and boot. The appimage must be present in the SD card by the name app. On succesfully sending the image, application sends a magic word to mark the completion of transfer and marks the relative offset to which the image is sent to.
