2.3 Powering-up the DLPC7540EVM and Preparing to Program the DLPC7540EVM

There's only one jumper that is included with the DLPC7540EVM. This jumper is installed on J67 during normal operation between formatter and front-end boards. Before powering up the EVM for programming, ensure the included jumper is installed on J9 instead. The jumper locations are listed in Section 3.1.

Table 2-3 Reference Designators
JumperDescription (Bold Indicates Default Position)
J67 - Front End 5 VUninstalled - 5 V not supplied to J3
Installed - Formatter board provides 5 V to Front-end board over J3 connection
J9 - Hold in Boot LoaderUninstalled - Normal Operation
Installed - Hold in Boot Loader

Jumper J9 is the Hold BL jumper. This jumper is used to put the DLPC7540EVM into boot loader mode, which allows the DLPC7540 controller to be programmed. Connect this jumper to prepare the DLPC7540EVM to be programmed.

To power up the DLPC7540EVM, a 12-V, 5-A power supply is needed. Ensure the power supply is functional and the switch SW5 and SW1 on the formatter board are set to off before connecting the power supply to the EVM. Connecting the power supply when the switch is in the off position may prevent damage to the DLPC7540EVM from poor power connections. The image below shows SW5 and SW1 and their operating positions.

Once the power supply has been connected to the DLPC7540EVM, the switches SW5 and SW1 in that order can be flipped to the on position. You can then plug in the USB cable to J2 of the board to prepare for programming the board. Verify that D5, D6, D7 and D15 LEDs are on.
