Hi,
We are planning to get additional soft UARTs by implementing PRU UART on OMAPL138EVM.
We integrated the latest patch for DaVinci-PSP-SDK-03.20.00.12 release and with this, we get PRU UART transmit (from EVM) working for various standard baudrates except 38400 bps. Receive (to EVM) at 38400 bps is working fine, whereas transmit at 38400 bps shows junk characters.
We use teraterm/hyperterminal on host PC side.
We run EVM at 300 MHZ. Does any one know, why it is not working specifically for 38400 bps ?
Interesting observation is, when I transmit data at 38400 bps, I can receive that data on PC side at 115200 properly, but not at 38400 bps.
Is there any bug in PRU SUART driver for transmit at this baud rate? Has anyone faced any such issue with PRU UART ?
Thanks,
Sweta
