T2080 just wont come out of reset..

PORESET_N is negated by fpga

SYSCLK is stable around 50msecs before the negation of PORESET_N

However the T2080 asserted HRESET_N around 500msec earlier when all the T2080 power rails are valid..

 

So generally

PORESET_N low

Power rails ramp

After ramp HRESET_N driven low

CLKSYNTH_RST negated 450ms later

CLKs stable 1.5ms later

PORESET_N negated 50ms after CLKSYNTH_RSTn negated.

 

I see no access on I2C0.. with PORcfg resistors setup for I2C RCS access.
