If you get the -180 error message with xdsprobe it means -
a. you have no power
b. the JTAG cable is disconnected
c. your options for xdsprobe are not correct [I pick this one]
You can get the xdsprobe manual by entering 'xdsprobe -hv >
xdsprobe.txt'.
Also, xdsprobe will only work with TI emulators or other emulators that use
TI's emulation drivers and a software adapter [Blackhawk, DSPR, Kane, and
others] - what kind of emulator are you using??
If CCS comes up with cpu2 in bypass then the problem is not scan chain
related - it most likely has to do with hardware connected to CPU2. The
most likely causes of you problem are
1. manufacturing or board defect
2. external device asserting "not ready"
3. the boot mode is HPI and DSPINT has not been asserted

Hi,everyone. I am debugging a board with 4 C6701 in a JTAG
chain. Some days ago,I could get into the CCS and access the onboard
resources. Later,I couldn't bring up the CCS when the CPU2 is in the
JTAG chain. So I have to BYPASS it in the CCS Setup to go on my debugging
and in the most time,it is ok. But now,when I get into the CCS, I cannot
access the onboard SBSRAM and the CPU peripheral control registers are all
0X0FFF0000. When I execute "CPU reset",the message is:
"Failed
Software Reset: Error 0x00000028/-1076 Error during: Break Point,
Execution, Cannot set/verify breakpoint at 0x00000000".
When I
execute the xdstrobe.exe, it comes:
"This error is generated by
TI's USCIF driver.
The error's value is: `-180'. The error's title is: `SC_ERR_CTL_NO_TRG_POWER'.
The
error's explanation is: The controller has
detected a target power loss. The user may have failed to turn-on or
connect its source."
What is the meaning?
