TMS320F28379D: tformat library GPIO assignment

Lisa Ding

Part Number: TMS320F28379D

Hi Champs,

my customer would like to change SPI-B GPIO setting to another GPIO which also route to SPI-B module. I will list release library setting v.s. customer setting. Could you please tell me can customer do this change? thanks for your reply in advance.

Release library (tformat)	Customer setting
GPIO34 - TxEn	GPIO59
GPIO24 - SPISIMOB	GPIO60
GPIO25 - SPISOMIB	GPIO61

Lisa,

What library are you referring to? If you look that the device data sheet, you can see that the SPI signals are muxed to many different GPIOs. Any GPIO that has been muxed with the required SPI signal can be used. Refer to Table 4-4 GPIO Muxed Pins in the device datasheet for the full GPIO mux. www.ti.com/.../tms320f28379d.pdf

This is a standard GPIO configuration. Though the customer is requesting specifically about the SPI, the same is true for all of the other peripheral signals.

Thanks,
Mark

Lisa,

As described in the library document -

TxEn: GPIO34 is used for this purpose on IDDK and example projects. User can choose any GPIO with OUTPUTXBAR1 mux option.

SPI: Any GPIO mux option is fine.
