Hello everyone,
I'm facing a similar issue of this thread posted by Ashutosh Pailwan1.
I've got (Error -1155 @ 0x0) Device may be operating in low-power mode. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
I've tried to lower TCLK and I still get the error. I followed the measurements discussed in the followed thread and all seems to be the same, one exception on XRS that does not toggle, just is pulled up in 3V3. The odd thing is that the XDS100V2 JTAG DR Integrity scan-test has suceeded.
I used as well a C2000-Gang programmer and still can't flash the uc. The cable for JTAG is a Tag-Connect Cable with less than 3 inchs.
Any advise on this kind of error?
See bellow my schematic. I did based on TMS320F28027 Launchpad.
