Part Number: TMS320F28P550SJ
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hi team,

I ask this for my customer.

They use LP-F28P55, and it can be connected successfully in CCS.

But if it use Unilfash, it will fail. I try it in my LP-28P55 and Uniflash9.1, Uniflash 8.7, use below three methods, all method fail.

1. Use detected device directly

2. Choose Device and Connection manual

3. Select a ccxml that in SDK

All method fail when it try to do anything(read memory or erase) and show below error

Could you tell me how to do it?

I believe I know the root cause. When you do the manual selection below:

Use the "Edit" open and set the mode to 2-pin cJTAG:

The issue is that UniFlash defaults to standard 1149.1 JTAG which will not work with the LaunchPad.

Thanks
