Attached folder comprises of a simple LED blink code for all the 3 cores in ADSP-SC58x processor. Apart from that it also has a loader stream generated for SPI master boot mode for various combination.

 
These loader streams can be programmed into the flash and SPI master boot can be tested.

      Hmm..... the problem has been solved....
      
 
      It turned out that the example *-ldr file puts the Core0 (ARM-Cortex A5)
      into thumb state.
      
 
      How to debrick:
      
 
      Start OpenOCD (the one from ADI's Linux CCES AddIN).
      
 
      Open GDB:
      
 
      target remote :3333
      
 
      (issue this command when you release the reset push button) - so the SW from SPI-NOR won't start.
      
 
      (gdb) set $cpsr = 0x1D3
      (gdb) load /opt/analog/cces-linux-add-in/1.1.0/uboot-sc58x-1.1.0/bin/init-sc58x-ezkit-lpc.elf
      C
      
 
      Ctrl+C
      
 
      (gdb) load /opt/analog/cces-linux-add-in/1.1.0/uboot-sc58x-1.1.0/bin/u-boot-sc58x-ezkit-lpc
      
 
      C
      
 
      And you should see the output from serial console :-)
      
 
      After that one can restore the original u-boot/Linux.
      
 
      Sorry for the noise :-)
      
 
      Best regards,
