Tool/software: TI C/C++ Compiler
Hello
I asked the question "How to burn C2000 series of F28069 via Jtag or ft2232 mini module" before
I make the controller of F28069 microchip on our own, but I lack the programing circuit .
The connecting from computer to F28069 via Jtag XDS110 is failed.
the error code is following
The value is '-233' (0xffffff17).
The title is 'SC_ERR_PATH_BROKEN'.
The explanation is:
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.
1.I find a circut for Jtag between Header from XDS110 to C2000 F2806X chip
The datasheet and technical reference of F28069 say that there are no EMU0 and EMU1 on F28069.
Therefore,I change the pull-up resistor to 4.7,instead of 3.3K ohm.
However, the results remain same.It fails either.
2.I look up to XDS Target Connection Guide Design guidelines for JTAG
http://dev.ti.com/tirex/#/?link=Development%20Tools%2FDebug%20Probes%2FXDS%2FDocuments%2FXDS%20Target%20Connection%20Guide
dose it requres a 22ohm between RTCK and TCK?
but the 9th pin on 20- Pin of XDS110 is NC, not TRCK 
what I need to solve my problem
Thank you very much
