I am confused by the etrax documentation, the hardware manuals and the kernel setup nomenclature differ in what names are used for the same hardware devices. My problem is that we are using serial ports 0 and 1 along with sync serial 1 in kernel config.
The Hardware engineer says we are using sync serial P3. Is sync serial P3 the same as sync serial 1 in kernel config? And is it possible to use this configuration of serial 0, serial 1 and sync serial 1 at the same time. I have sync serial 1 configured with no dma.
