CCS/TMS320F28069F: how to program F28069 by USB ?

I am using F28069UPZT

Hi Kyrie,

Are you asking how to do this from a Hardware or Software perspective?

There's usb and serial flash programming support within C2000ware, but I think the usb programmer content is meant for F2837x and may need to be altered. Located at the C2000ware directory below:

C:\ti\c2000\C2000Ware_2_00_00_02\utilities\flash_programmers

Best,

I have 2 qiestions

First,Is my hardware able to programming by usb?need other ic? btw i'm using jtag to program all function is work

Second, Is about software like you said

Hi Kyrie,

HW wise you should be OK.You can check the USB section 17 of the TRM for additional information on HW concerns:

What value is the resistor on USB_vcc? It should be 100K or close to it to prevent over-voltage on the I/O buffer (USB_vcc is usually ~5V). Also D+ and D- should be differentially routed with 90 ohm characteristic impedance.

SW wise I'll try and have someone else comment that has more expertise.

Best,

Kevin
