Hello, 1. Yes, you can use a flash kernel to update any portion of flash. 2. Yes, the BEGIN memory section in the CPU1 linker file is the address you should branch to. The CPU1 application can then configure CPU2 and take it out of reset. 3. Yes, this is reflected in the source code. CPU2 images are programmed through the CPU1 kernel. For a reference on how the CPU1 application can allocate memory (RAM and flash) to CPU2, please refer to any of the multicore examples in C2000Ware. For example, you can refer to the LED blinky example at C2000Ware_Location \driverlib\f28p65x\examples\c28x_dual\led. 4. Yes, flash_kernel_x28x_dual_ex1_sci_get_function.c defines most of the functions that interact with the host. Kind regards, Skyler
