We designed a board which refer to the B4860QDS Evaluation Board. Recently, we met a problem when reseting the chip. Sometimes, we reset the chip, it respond nothing. So, I think the B4860 chip hult running. Our schematic is designed refer to B4860QDS, and we removed some parts of B4860QDS schematic, include K10 part.
So, I have two question about that:
a) What may case the problem we have met?
b) I deleted the K10 part, is that effect the reset sequence?
