Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

1. if i want to be able to update firmware from usb driver, which boot mode should be selected: sci/spi/i2c/parallel?

2. is there other IC needed in between the microcontroller and the usb connector?

3. is there a example i can refer to accomplish this task?

Thanks!

    Hi Shengnan, 

    1. Which peripheral are you intending on using? There is a SCI flash kernel example that uses SCI boot mode to update firmware for this device. Please take a look at www.ti.com/lit/sprabv4 for more information. 

    2. Usually a transceiver is needed for the microcontroller to be able to read in the transmissions from the USB connector. 

    3. There is an example that demonstrates how to perform firmware upgrades over SCI - please refer to the app note linked above, the path to the example in C2000Ware is shown there.

    Thanks, 

    Anu
