I've installed the C2000 Hardware Support Package but it does not seem to contain support for the f28377s mcu. Do I need R2015x to use this?

Hi,
With the release of R2016b, support package version 16.2.2, we are now supporting external mode on all the GPIO pins that can be configured for SCI_A via the SCI_A pane (Hardware Implementation->Target Hardware Resources-> SCI_A). However, which GPIO pin for the given board needs to be selected is dependent on the board schematic. If the user has a custom designed board, then user must configure those GPIO pins for SCI_A which are routed to serial port/FTDI chip. Bottom line is, any GPIO pin which support SCI_A functionality can be configured for external mode, but which GPIO pin is used on the given board for SCI_A is for users to investigate. Some popular board from TI and their default GPIO pin assignment for SCI_A are as below:
For F28377S Launchpad, FTDI connected to GPIO pins GPIO84(Tx) and GPIO85(Rx)
For F28379D Launchpad, FTDI connected to GPIO pins GPIO42(Tx) and GPIO43(Rx)
For F28377D Controlcards,FTDI connected to GPIO pins GIO29(Tx) and GPIO28(Rx)
Selecting internal oscillator works for F28379D Launchpad for following reason: the external oscillator on this launchpad runs at 10MHz, but our default value for Oscillator clock (OSCCLK) frequency in MHz is 20MHz. This default value is true for a F28379D control card but not for launchpad. When user generates the code keeping this default value and tries to run it on Launchpad, we get incorrect value for the PLL multiplier as we are generating it for a 20MHz oscillator but launchpad has a 10MHz oscillator as noted above. This in-turn affects the calculation of other parameters like SCI baud rate which affects the external mode. However, selecting internal oscillator for the launchpad seem to do the trick, upon selection, we no more default to 20MHz but use actual value of the internal oscillator i.e 10MHz, to derive the PLL multiplier. This keeps other calculations consistent and thus external mode works. It would be better if the user is able to change the external oscillator frequency “Oscillator clock (OSCCLK) frequency in MHz” from default value of 20MHz to 10MHz if he plans to work with F28379D Launchpad against the current solution of selecting the internal oscillator.
