Programming flash with JTAG and C6713

Started by z_11...@yahoo.com December 5, 2007
Dear all

I have a design with C6713. I want to program flash with c6713 and JTAG. Can I use JTAG for first boot configuration? How? How can I program flash in this condition (by JTAG) before any initializing or configuration on c6713?
If C6713 need special configuration, please guide me. Is it possible to changing boot mode to EMIF boot and copy my data from flash then run program?

Really appreciate for your help.

It's not clear to me what you're trying to do... but a couple of comments that might
help.

1) If you have a Flash device that can be programmed via JTAG, then be sure to
separate the DSP and Flash JTAG chains. It's very unlikely you can get things to
work by putting them on the same chain.

2) You can program Flash via JTAG while DSP is held in reset. You can program Flash
via DSP during normal operation.

Hi there,

Can you actually plug your JTAG probe (TI probe connected to CCS) to your C6713?
If yes, you just have to initialise your processor using a Gel file, and then load a program of your own that will flash your data into the Flash memory.
No special configuration is needed, it is just better to set up the speed and EMIF registers.
if you do a reset, the first 1024 bytes will be loaded automatically from Flash to internal RAM, and here you can start.

Hope it helps
