I have LTC6813 and TMS570LS1224 development board .i am trying to read voltage through spi communication.
But in SOMI pin nothing is coming.
my cs clk and mosi is working fine.
please guide me.
Check for POL, PHA settings(1,1). SPI clock frequency (<1MHz), Pull-up on MOSI and MISO pins.
Next thing to check for is Vreg, Vdrive voltages. After wake-up ~5V should appear on Vdrive for 2 sec.
Please see my configuration.my halcogen version is 04.07.01.4555.spi3_integr_test.zip
please reply .
