Tool/software: Code Composer Studio
I am trying to program a custom board based on launchpad design.
I assembled the hardware and it is getting detected in the Flash Programmer.
However whenever I try to debug it using CCS, I get following errors:
Cortex_M3_0: Error: (Error -1170 @ 0x0) Unable to access the DAP. 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). (Emulation package 8.3.0.00003)
Cortex_M3_0: Trouble Halting Target CPU: (Error -2064 @ 0x0) Unable to read device status. 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). (Emulation package 8.3.0.00003)
I checked following things:
1) VDDS, VDDR, DCDC voltages are in expected voltage range
2) Reset pin is pulled high and I observed it on oscilloscope for possibility of repeated resets. This seems not to be the case.
3) Mass erase uniflash or flash programmer is successful. However after this I still get the same error.
4) Tried changing cJTag frequency till 100 kHz (minimum value), this does not make any difference.
I have attached schematic for the reference.
