Original question:
Tool/software: Code Composer Studio
I use F280049C launchpad and Controlcard for firmware code testing.
There are no problems in controlcard(JTAG-XDS100v2). But there are some ploblems in launchpad(cJTAG-XDS110).
I use notebook and desktop. When I using "Test Connection" in CCS 8.3 with my desktop, it shows 'SC_ERR_PATH_BROKEN' error.
My test procedure is :
1. Connected launchpad to the notebook and download XDS110 firmware with xdsdfu command
> xdsdfu -m
> xdsdfu -f firmware.bin -r
2. "Test connection" in CCS8.3. Test result shows "The JTAG DR Integrity scan-test has succeeded"
3. Connected launchpad to the desktop and "Test connection" in CCS8.3. Test results paused after below texts.
4. Few senconds later, USB driver's are reseted.... I guess that, it's initial state of TM4C129ENCPDT.
5. Few senconds later, JTAG driver shows again, but test results shows "SC_ERR_PATH_BROKEN".
After procedure 5, it's shows same results to connected to the notebook. But it's shows "The JTAG DR Integrity scan-test has succeeded" message after procedure 1 and 2.
I have tested other computers, it shows same results.... Some computers shows succeeded... Some computers shows error.....
Can I solve this problems?
Is this USB driver problems or not?
