Linux/AM6548: UARTs in DTE or DCE mode?

Matthew McKee

Part Number: AM6548

Tool/software: Linux

Hello,

We're working on connecting a Bluetooth device over UART and are having trouble getting the UARTs on the AM65x to communicate with the device. Can someone verify that the UARTs on the AM65x operate in DTE or DCE mode? Also, any additional detail on if it's possible to configure the UARTs to communicate with devices that expect to be connected with a device either in DTE or DCE mode would be appreciated.

Thanks,

Matt McKee

    Hi Matt,

    I believe the terminology of DTE/DCE is for 'serial port', such as RS-232, and not applicable to UART. In other words, The UART is capable to work as either DTE or DCE, this is decided by userspace applications, not UART itself or kernel drivers.
