Our customer would like to use PI0 and SPI1, UART0 to UART2, I2C0, RMII on AM1808.(Please refer to Pin set up)
When they set MDIO CLK and MDIO D of RMII,
Chip Select 0 (SPI0_SCS0) and Chip Select 1 (SPI0_SCS1) cannot be selected in SPI0.
Chip Select2 (SPI0_SCS2) and Chip Select3 (SPI0_SCS3) can be selected
Are these the right MUX configuration specification of AM1808 ?.
If there is any problem please let us know .
On the other hand
They plan to connect only one SPI device and don't need to chip select.
In that case, is it possible to use ENA instead of CS?
SPI0 will be used for MASTER and SPI1 will be used for slave .(But reverse configuration is also Okay)
Could you advise proper I/O configuration with PI0, SPI1, UART0 to UART2, I2C0, RMII on AM1808 ?
