TMS320F280049C: TMS320F280049C boot mode

Part Number: TMS320F280049C

Hi there,

Is it necessary to connect GPIO24 & GPIO32 to the pull-up resistors respectively to prevent entering boost mode?

I am also wondering if it is okay to use GPIO32 as a signal pin and leave GPIO24 floating.

Regards,

You cant leave GPIO24 as floating.

For more flexibility you can check if the custom boot configuration helps. The details are covered in TRM.

Hi Baskaran,

Thanks for your timely reply.

I want to make sure I didn't understand anything wrong, should both GPIO24 and GPIO32 be either connected to pull-high resistor or pull-down resistor?

Is there any other configuration examples of boot mode setting?

pull-up or down depends on the boot mode you want to achieve. which boot mode do you want to configure.

There is no example as such, the TRM has enough details for custom boot mode configuration.
