Boot from SPI Nor flash directly

haopeng han

Is there any demo code/project for directly boot C6678 from SPI Nor flash? The example in MCSDK is booting from Nor over i2c.

Thanks in advance.

Unfortunately no. But SPI boot is similar to the I2C boot. The utilities that you use for the creating a EEPROM image for I2C boot can be used for the SPI boot.

Thanks,

Arun.

Han,

On the C6678 rev 1 silicon EVMs, regardless of the boot strapping, the DSP first boots from I2C, then it re-enters the bootrom and boots using the mode the is pin-strapped. This is due to the PLL fix that is needed. SPI does not require the PLL fix though, since it uses the bypass mode of the PLL. The MCSDK example should work regardless of going to the I2C or not. Now the utilities for generating and programming the SPI image into the NOR flash are the same for both i2c and SPI.

Regards,

Travis
