I have a LM3S9B92 evaluation kit, which has the microboard and the FTDI Jtag board. I had got it working, and managed to get the demo program to work.
I started working on my code which was to use the SSI part of the Micro. Am using CCS V4 to create the code. Now I am unable to communicate in any way with the micro using the LM Flash programmer. The programmer version is build 1381. I try to do a Blank check, and I get the error message. I searched the web and the forum and came across the reset for the micro. This too does not reset the micro or initialise the jtag section.
The Debug port unlock process on LM Flash - if I select Tempest and Firestorm classes, as suggested for my micro on another post, I get a "Error - Unable to initialize target - 1" error message. If I use the Fury, dustDevil, classes - I do not get the error message, but it has not resolved my issue of being able to reset the micro.
I have a scope on the jtag signals, TCK and TDO. What I am seeing is that the ftdi board, on a request (e.g. Blank check) , sends out a single pulse, which is not at the setup frequency of 100kHz. The error message appears. On pressing the OK button, the scope shows clock signals and transmission data on the jtag pins at the requested frequency.
The micro on the evaluation board is a LM3S9B92 B1. The ICDI board has a FTDI - FT2232D chip on it.
Did you resolve this problem? Or you had to change the micro?
I have the same problem, but with a LM3S5791-C5. Problem occurred when CCS freezed in a debug session. From that point, no more connection could be made.
