Hi List, I am quite new to uClinux and have a question if there is any common practice for such a case...
I have a Coldfire MCF5373L in an embedded design where I want to use the SSI lateron. However, as the SSI shares pins with the second serial port (UART1) and the GPIO module is set up during UART initalisation, I have to disable UART1 completely in the driver. How would one handle this in a way that it might be re-usable? The possibilities I see are: - just count the UARTs starting from 0, resulting in a mapping UART0 -> ttyS0 UART2 -> ttyS1 (this has the disadvantage of ttyS1 being a different port when I run on a standard kernel or on my patched kernel) - give the UARTs their "hardware number" UART0 -> ttyS0 UART2 -> ttyS2 Like this, I could always use ttyS2 during development regardless if I run on a standard kernel or my patched kernel. However, the "missing ttyS1" looks a bit strange to me... I know this may be silly questions because in the production system, I do only have one kernel, but at this stage I would like to make all the changes as clean as possible.
