TMS320F28386S: Serial flash programmer kernels for CM

I attempted to post this earlier but no longer see it, I beg pardon if it ends up double posted.

I am trying to use the serial flash programmer to update the CM and as usual I am confused, this time about which kernel to use.

There is a project flash_kernel_c28x_cm_ex1_c28x1 with the file flash_kernel_c28x_cm_ex1_sci_flash_kernel_cpu1.c.

The 2nd project is flash_kernel_c28x_cm_ex1_cm with file flash_kernel_c28x_cm_ex1_sci_flash_kernel_cm.c.

Which one's outfile do I convert and use with the -o option? The 2nd one? Then would the first be used with the -k option?

Thanks,

John
