Hi,
I am using TMS320F28027 MCU and CCS 5.4 to debug my code using Spectrum Digital XDS100v2 Emulator. The Target Configuration settings are as follows:
Connection: Texas Instruments XDS100v2 USB Emulator
Board or Device: TMS320F28027
Board Data File: auto generate
Emulator Selection: Only one XDS100 installed
The JTAG nTRST Boot-Mode: Disabled - Both EMU pins remain hi-z
The Power-On-Reset Boot-Mode: Disabled - Both EMU pins remain hi-z
The JTAG TCLK Frequency (MHz): Fixed default 1.0MHz frequency
I have my own hardware. Part of the hardware that I am working with is attached. I can program my code and debug it easily but sometimes (without no reason in my point of view) I get the following error:
C28xx: Error connecting to the target: (Error -1015 @ 0x0) Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible, and power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.73.0)
I can not program it anymore. The MCU locks without no reason and the only solution I found was to change it.
Can anyone help me with that? Is there anything wrong with my hardware or settings? Why it works sometimes but it locks suddenly!?
Thanks,
Ali
