Other Parts Discussed in Thread: TMS320C28346, UNIFLASH

Hi, everyone.

I`m using TMS320C28346 device.

And I have a two questions about program security.

1. As a title, how can I get the secure device? I don`t know anything that. Is it a special device? or program tool?

I already read the user`s guide, but I don`t understand "Custom Encryption"

Is there a any other document?

2. When I burn my program into the eeprom, is there a way to make encryption?

For example,

My program(*.out) is converted to hex file by hex2000. At this time, the hex file is encryption code.

Then some boot-mode is decrypted the program for stand-alone acting.

Is this possible?

Thank you.

Hi,

You can make use of an utility called CCS Uniflash for locking and unlocking the device.

Go through this link: http://processors.wiki.ti.com/index.php/UniFlash_Quick_Start_Guide

As sold, this is a RAM only device without a method to program the password for code security. If such a password is required, then a a device with a custom ROM can be ordered at a fee/minimum order.

Thank you for answer.

Hi Lori

I almost understand that. Thank you for your help.

Additional questions is below.

1. So then, Did C28346 has CMOS ROM version? Like C2812/F2812?

2. And What is "secure boot"?

Is "Secure boot" for "a device with custom ROM" what you said?

Thank you.

It does not have flash available. Only RAM and the option to engage with TI to include a custom ROM.

Yes - this is enabled using a custom ROM. The ROM requires a minimum build and NRE.
