> my ROM is not boot from spi after reset the core((

What exactly does this mean?

Please provide detailed technical description of the issue.

Consider that for normal processor rebooting it is required to perform the SOC reset (by applying HRESET_B) - not only the core reset.

It is possible to assert by software HRESET_REQ_B external signal, which has to be used in the design to generate HRESET_B pulse - refer to the P1010 QorIQ Integrated Processor Reference Manual, 4.5.1.2 Hard reset.
