I have a MAX3232 connected to UART5 on a BBB. During power up; presumably before the dtb has been loaded to set the pinmux for the UART, I see a "break" sequence being sent. A break sequence is defined as "tx held low for a duration longer than 1 frame".
Seems like pinmuxing won't help because it occurs too late. According to the am335x data sheet the "zero state" for the corresponding pin is Z which presumably means the pin will be low (i.e. "emitting" 0's) until the pinmux takes over and configures it as a UART pin which presumably brings it to idle (high). Any ideas how to avoid this? Thanks, -W -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
