I have faced a weird phenomenon on our custom board based on an LS1046A.
In a CPLD I've implemented a power and reset sequence. I was able to bring up our board, the Linux runs correctly from the onboard eMMC,
the LS1046's RESET_REQ_B constantly pulled down. During the reset sequence it goes high then goeas back low
Despite of this everything seems to be OK.
But I don't understand this phenomenon.
Has anybody faced this before?
thanks in advance,
