1.1 If You Need Assistance
If you have any feedback or questions, support for the Sitara MCUs and the AM243x LaunchPad development
kit is provided by the TI Product Information Center (PIC) and the
TI E2E ™ Forum . Contact information for the
PIC can be found on the TI website . Additional device-specific information can be found in the Section 5.1 .
1.2 Important Usage Notes
Note
The AM243x LaunchPad requires a 5 V, 3A power supply in order to function. While a USB type-C
cable is included, A 5 V, 3A power supply is
not included in the kit and must be ordered separately.
The Belkin USB-C Wall Charger is known to work with the LaunchPad and the supplied type-C cable.
For more information on power requirements go to Section 3.1 . If there is an error in the power input
then the red LED (LD9) will glow continuously. For more information about the power status LED's,
see
Section 3.1.2 .
Note
The JTAG connection through the micro-B USB port needs to be made after power is supplied to the
LaunchPad by the USB type-C connection. The JTAG may not connect if the micro-B USB connection
is made before the 5 V, 3A connection is made. For more information on JTAG emulation go to
Section 4.15 .
Note
For E1 and E2 revisions of the AM243x LaunchPad, some output signals are not able to propagate
to the BoosterPack headers. Any pinmux configuration that is an output signal for balls R21, T19,
U18, U20, V20 of the SoC will be gated by the isolation buffer U32 because the DIR pin of the buffer
is low (only allowing data transfer from side B to A). The signals that not able to propagate to the
BoosterPack headers include: UART2_RTSn, EHRPWM2_A, EHRPWM2_B, as well as any GPIO
signals on the listed pins.
