i have a 6678EVM and when it boots from NAND I can get access to linux command line on core 0
(using minicom),

all thing with linux is true but i wanna run my own programs on core1 (using on board XDS100 jtag and CCS)

now how can i run core0 from NAND and core 1 from Jtag? is it possible?

thanks, dido.

Hi, Dido,

In CCS, you just connect to any DSP cores other than core 0, and load your program to it. I am not sure if you have visited SYS/BIOS MCSDK website, but here is the link to SYS/BIOS MCSDK for application on non-linux cores.

Hi Rex

So what is the correct configure for SW3-SW6 on EVM to boot core0 from nandand core 1 from jtag?

Hi, Dido,

The dip switch should set as boot from NAND. You are not booting the DSP. They are just powered on and can be connected through CCS.
