We have built a custom board with the LMS7002M chip and are trying to establish SPI communication with the chip.
For the same we are using the drivers provided on git. The SPI interface is running at around 8MHz and has been validated independent of the LMS interface.
The chip version is being read as the first step. The procedure we are following is:
- LMS_RESET (low followed by high)
- read 0x002F register
We are unable to read anything.
- Any help on getting this first step going
- We are feeding a 50MHz clk on the rx_pll_clk pin of the LMS. Is the clock supposed to be fed on some other line? How does the LMS chip choose this clock for the uController running the SPI interface
- How is the 3 wire or 4 wire interface chosen?
Thank you for time,
