Is spi_master_example_with_spi_slave in SDK6 correct???

[jimlin]

Use the spi_master_example_with_spi_slave in SDK6 to evaluate the SPI master module but fail. No matter use the default pin assignment or re-assign, it does not give out the correct SPI bus. The CLK drove by the 51822 is not correct, not a clock signal at all. The same as the others.

Is there anything need to config or award? Could this demo work or not? The experiment runs on the minimum system with 51822 and neccessary component only.

I would try:

1. Run example on one of the Development Kits.
2. Make sure 51822 is the same as defined in the project regarding memory size.
3. Make sure hardware is fine, all power and ground pins connected, power rail is stable, within the range and has decoupling caps. In case of BGA chip are you sure that PCB is good and all pins have connection to external components/test points?

Try changing clock frequency, just to see what will be the difference.
