I have two sensor communicate with DSPI0 with two chip select. One chip select works what I expect. But second chip select do not work properly. I think second pin may be crush or something and I change the second chip select's pin. I try four chip select pin for this purpose and I see only first one works. I do not understand why this happen. Is this problem cause for software or hardware I do not know actually.
First chip select PCSA0(it works):
Second chip select PCSA1(it does not work; interestingly chip select's reset state around 0.4V (I expect 5V)):
PCSA2: I do not use this pin because I do not see this pin in my motherboard
PCSA3(this pin does not work): When I select this pin as a second chip select This pin always in low state (0V):
PCSA4(this pin does not work but it has interesting output): When I select this pin as a second chip select it does not work and generate interesting output:
PCSA5(it does not work): When I select this pin as a second chip select This pin always in low state (0V):
By the way I use this motherboard:
And Which information I use for determine the chip select pins:
And lastly I want to share with you what configuration I did about software:
They are jumper for ethernet PHY on these pins (routed to motherboard). Check them, whether you have them in place or not.
