We are using Beagle-Bone-Black as the controller.
We like to use SPI1 for one of peripherals with two chip selects and we have use pin D18 as CS0 while pin D17 as CS1.
SPI1 clock and data are pin A13, B13 and D12.
However the PINMUX tool reports resource conflict even if nothing but only SPI1 assigned.
Was this because the reset release mode of the pin or something else? Thanks.
