    Hi Huajin,

    Please provide your DSP C6678 chip version? (Eg: PG1.0 or PG2.0)

    The PLL fix implemented for PG2.0 was to fix an issue w/ PLL initialization only, on 1.0 this required the use of an I2C ROM to configure the PLL properly for the initial configuration.

    For more information refer "Advisory 8 Multiple PLLs May Not Lock After Power-on Reset Issue" on C6678 Silicon Errata document.

    huanjin yuan,

    Direct boot from NAND is not supported in C6678 devices. Please refer to section 2.5 of the device datasheet to look at supported boot modes. The support for direct NAND boot using boot ROM was introduced on C6657 in Keystone I device family.

    Hence in order to boot using NAND on C6678, you would need to use IBL code.


    Regards,

    Rahul
