Just FYI,
I tried by changing id field in board-zoom-debugboard.c for external UART to -1, which in theory would add a ttyS4, but somehow it didn't worked for me...
I guess the proper fix will be to have:
ttyS0 - OMAP3_UART1
ttyS1 - OMAP3_UART2
ttyS2 - OMAP3_UART3
ttyS3 - OMAP3_UART4
ttyS4 - ZOOM_UART
Any Zoom debugboard expert that wants to comment on this?
Regards,
Sergio
