F2837xD board setting  

Defino series TMS320F2837xD check below three pins at the reset to decide the booting mode.

 MODE

 GPIO72   GPIO84 /TRST

 Boot mode
 Mode EMU X X 1  Emulation Boot
 Mode 0 0 0 0  Parallel I/O
 Mode 1 0 1 0  SCI (RAM boot)
 Mode 2 1 0 0  Wait Boot Mode
 Mode 3 1 1 0  Get Mode (factory default = boot to flash)

easyDSP uses two kinds boot mode. SCI boot mode for RAM booting, GetMode boot mode for flash rom booting.  
Below connection is recommended between easyDSP and MCU.
Note that  GPIO84/85 should be used for SCIA. Please check 'How to use different port ?' session in case external memory interface is necessary.


You need to use two easyDSP pods to communicate with both CPU1 and CPU2.
one easyDSP connected to CPU1 should use SCI-A (GPIO84/85 fixed).
The other easyDSP connected to CPU2 can use either SCI-B, SCI-C or SCI-D but easyDSP recommends to use SCI-B GPIO 87/86 as default in its source file (easy28x_DriverLib.c or easy28x_bitfield.c) .  
If another GPIO port is required in your system, please change the hardware connection and modify the easyDSP source file (in the function of easyDSP_SCI_Init) accordingly by yourself.

- Factory default setting is assumed (Don't change it)
- power pin (#4) of easyDSP 5x2 header should be connected to 3.3V
 - TX/RX pins are directly connected to MCU pins
-  In case there is a reset IC between easyDSP /RESET and MCU /XRS, it should transfer easyDSP /RESET signal to MCU /XRS within 0.5sec 
- In case you insert buffer IC between easyDSP header and MCU, place buffer IC directly to easyDSP header so that all resistors can be connected to directly MCU
- /RESET pin is connected to reset generation circuit of MCU board
  (Time duration of /RESET pin is around 500msec)
- In case you use pull-up resistor to each pin, the value of pull-up resistor should be higher than a few kilo ohm since there is 100Ω series resistor inside easyDSP pod
- Refer to here  for BOOT pin operation mode.

Please be careful when you use your own pull-up or pull-down resistor on the easyDSP signal pins. Please use appropriate filter circuit to your reset generation circuit to prevent unintentional reset generation.
