Tool/software:
Hi TI,
We put TPS2384 in Intel I350,
and use SDP to send I2C command,
when use I2C commnad 0x00 to read chip ID,
it is 10b in PCIE x4 slot,
but it is 11b in PCIE x16 slot,
however if we set PCIE x16 slot to gen 1,
the chip ID turns back to 10b,
is any thing causes to read different chip ID?
how to fix?
Attachments:
1. snap the I2C signal from PCIE x4:
Note: In red circle, there is some noise in when clock down.
2. snap the I2C signal from PCIE x16:
Thanks.
