LAUNCHXL-F28069M: JP6 e JP7

Expert 1065 points
Part Number: LAUNCHXL-F28069M


Hi All

www.ti.com/.../sprui11.pdf   

I took the below text from User Guide (section 5.2, see link above)of the LaunchPad. I suppose that the UART port used for Debug and upload of the program to the LauchPad is UART A, because it is not disponible in the output pins of the LauchPad. 

Can be explained what it is configured with JP6 and JP7?

Mainly with 2,3 and 4th line of the table

Thanks

Luis Gonçalves

Serial Connectivity
The LAUNCHXL-F28069M has a USB to UART adapter built in. This makes it easy to print debug information back to the host PC even in isolated environments. The F28069M device on this LaunchPad contains two SCI (UART) peripherals, while the LaunchPad has three places these peripherals need to be routed. Because of this, a serial connectivity mux has been added to the board to make configuration of the SCI routing easy. Routing is configured via two jumpers (JP6 and JP7). Configure the jumpers as shown in Table 1 for the serial connectivity you desire.
Table 1. Serial Connectivity
MUX_SEL CH_SEL(JP (JP7) 6) Function
ON ON USB/UART Disabled; J1.3 and J1.4 – GPIO28 and GPIO29; J7.3 and J7.4 – GPIO15 and GPIO58
ON OFF USB/UART – GPIO28 and GPIO29, J1.3 and J1.4 – Hi-Z; J7.3 and J7.4 – GPIO15 and GPIO58
OFF ON USB/UART – GPIO15 and GPIO58; FAULT/OCTW – GPIO28 and GPIO29; J7.3 and J7.4 – Hi-Z
OFF OFF USB/UART – GPIO15 and GPIO58; FAULT/OCTW – GPIO28 and GPIO29; J7.3 and J7.4 – Hi-Z

    Luis,

    The UART port accessible by the XDS100 Debug probe is a second alternate channel to output serial data to a connected PC. Due to pin limitations on the board and a desire to allow multiple options for using the UART, a Mux was added to allow a user to use either GPIO28/GPIO29, GPIO15/GPIO58 for the Channel B UART, or it can be disabled.

    Does this make sense?
