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
.

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.
