Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hi,

 when i am looking for boot mode configuration in TRM find pin for SCI_Mode as GPIO84/85 and GPIO28/29.

In lanuchpadxl f28379D manual mentioned SCI_Mode pin as GPIO72/85 is this correct ?

suppose if want implement SCI_Mode on Launchpad XL f28379D is this possible ?

What is the use of wait mode ? what would happen if use wait mode?

In Launchpad xl F28379D  Emulation mode is belongs to which communication  (boot_mode)?

Thanks & Regards,

Rani

    wait boot and emulation boot are for debug purposes, they cant be used for production system.

    GPIO 72 & 84 are used to select the peripheral. once you select SCI boot mode using these pins then you can use the options given in table 4.29 of TRM.

    Baskaran,

      Thanks  for the information about  wait mode & Emulation mode. In TRM mentioned SCI boot pins are GPIO84/85 and GPIO28/29 but launch pad given GPIO72/84 both are correct or is there any mistake? .

    Thanks & Regards,

    both are correct. 72/84 supports SCI functionality, but bootloader functionality is not supported on 72/84.
