Problem in reboot LS2160ardb

Dear community & nxp,

    I get a problem with reset the CPU. After entering reboot in the shell, the console has no output. By reading code kernel and ATF, the reset is done by using the operation register RSTCNTL(0x1e88180), set the SW_RST_REQ bit to put RESET_REQ_B in high level. After external hardware detecting the high level, the level of PORESET_B pin will be setting low to finish the reboot of CPU. But, the SW_RST_REQ bit is actual 1, RESET_REQ_B is still in low level. I want to know what the condition is for RESET _ REQ _ B pin in a high level and what I'm need to do to slove this problem ?

    Thanks in advance!

    Best regards!

just for record.

Reset request output. An internal block requests that PORESET_B be asserted.

So PORESET_B signal must connect to a reset unit such as cpld/fpga or direct to hreset or poreset.
