Hello Experts,
I am is Akhil Francis i am working on DSP f28335, and 14 pin olimex XDS100v3. I connected the olimex XDS100v3 and i powered F28335 from an external power supply. While loading the program i got an error 'SC_ERR_PATH_BROKEN'.
Error is
C28xx: Error connecting to the target: (Error -233 @ 0x0) 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. (Emulation package 6.0.14.5)
Then i checked each pins of jtag header while loading the target, i found that
EMU1 is high
EMU0 is low
TRST is getting high low
no pulse in TMS and TCK
TDO and TDI getting high low pulses
Then i checked the controller pins by giving the power to f28335 ,with out connecting JTAG, And i found
Both the EMU pins of controller are high
TDI is high
Is this is correct or not? How can i check/solve this problem? please give me a solution.
Thanks in advance
