AWR1443BOOST: SPI interface

Yves de Villers

Part Number: AWR1443BOOST

I would like to use the BP/LP connectors to tranfert out data of the device using the SPI interface. I'm able to see the signal comming out of the MOSI (J6-14) but I need the SPICLK (J5--13) but there is no signal comming out of the pin. I'm able to see the display in the visulaiser to be updated in real time. The SOP jumper are set to 001.

Dear Yves -

Thanks for the post and welcome to E2E!

Here you should make sure you have S1 set to choose SPI instead of CAN, on that board.

Hi Josh,

I verified twice this setting and it is on the SPI side. Since I'm able to have the data on the MOSI pin means the setting is correct.

Dear Yves -

Thanks for the response - perhaps then check pin 15 of U13 (the switch) in both positions to make sure you get GND or 3.3V, then if that checks good, check the same between pins 7 and 8, where you should see short or open based on switch setting. I don't see anything else at the moment in the schematic that would block you, other than that switch.
