1). Set the boot pins to emulation boot mode. This is done by setting switch S7 on the EVM according to the following table:
(S7-1:OFF, S7-2:OFF, S7-3:OFF, S7-4:OFF, S7-5:ON, S7-6:OFF, S7-7:OFF, S7-8:ON)
2). CCStudio and connect to the ARM.
3). CCStudio and connect to the DSP.
4). Open the ARM, From GEL menu-> Full EVM -> SPI1_PINMUX
5). On the ARM load spiflash_writer.out program.
