Not able to boot secure C6748 from SPI flash

I have been using a custom board with C6748 and SPI flash

In the new board replaced C6748 with a secure chip

Followed the steps for secure booting using secure collateral.

  • Unlocked the jtag and build the Hello world example program to print in UART0 terminal : Prints correctly
  • Application is to continuously print 'Hello World' in UART0 terminal (Appl.out generated)
  •  Converted Appln.out to Appln.ais using test.ini(attached) using secure hex tool.
  • Appln.ais works from UART boot Host and prints Hello World in the UART terminal.
  •  Flashed Appln.ais to SPI flash
  •  Used secureboot.ais through secure mode and did binding successfully (From Security Collateral SPIbinding with modification for SPI 0 flash and UART0 for logs)
  • Changed boot mode to SPI0 flash and application does not boot
