F2838x board setting

Defino series TMS320F2838xD check below two pins at the reset to decide the booting mode.

Since easyDSP uses two kinds boot modes, SCI boot mode (RAM boot) and flash boot mode. Below connection is recommended between easyDSP and MCU.
Note 1 ) 
GPIO28/29 should be used for SCIA
Note 2 ) factory default is assummed. Otherwise, the user should modify the configuration accordingly. 

You need to use three easyDSP pods to communicate with CPU1, CPU2 and CM all.
The easyDSP connected to CPU1 should use SCI-A (GPIO28 and 29 fixed).
The easyDSP connected to CPU2 can use either SCI-B, SCI-C or SCI-D but easyDSP recommends to use SCI-B as default in its source file.
The easyDSP connected to CM should use UART. easyDSP uses GPIO84/85 in its source file.
In case you uses another GPIO pins for CPU2 and CM, the hardware connection and easyDSP source file should be modified accordingly by yourself.

- Factory default setting is assumed (Don't change it)
- external clock source 20MHz is recommended
- 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
- /BOOT pin is connected to GPIO7
2 via 2kΩ series resistor
- /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

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.
