Hi,
I am using LMP90100 EVB from last year. But today, it suddenly out of work. I powered board externally using regulated DC power supply with 5V . But the current it extracts from the power supply is 8mA. This is awkward. I checked JP6, JP7 using a multi meter and they are approximately 5V. Then I checked JP14.P2 but it gave 4.1 V. I tried to read a register after writing to it. But it always gave 255. The code I used to this already worked properly in last year. I did not changed any syntax. SPI master is Arduino. I checked it's functionality using a logic analyzer. It works well. I am unable to figure what's wrong with AFE EVB.
Please help.
