Sir,
Am using TMS320F2812 kit ( XDS100 USB EMULATOR ) with Code Composer Studio V 4.1.0.02006. After Successful build , when am trying to connect ( Target - Connect target ) the target. am getting following Errors;
1. Error connecting to the target:
Error 0x00001200/-1135
Error during: OCS, Target,
Unrecoverable emulation error
if i retry then i get following error :
2. Error connecting to the target:
Error 0x00001200/-1041
Error during: OCS, Target,
Device driver: Problem with the Emulation Controller.
It is recommended to RESET EMULATOR. This will disconnect each
target from the emulator. The targets should then be power cycled
or hard reset followed by an emureset and reconnect to each target.
then i give cancel.. , Continue launching -- Yes . then reset emulator , then terminate all............. once again i started the from the beginning the same response at all times.
Notes For your referrence:
1. I monitor the 1.8v and 3.3v while target connect. it constant at respective voltage. no lag or lead in voltages .
2. am using 25 Mhz crystal ., and i checked . once i power the kit it producing the 25 Mhz clock with 168mv peak to peak.
3. I uninstall the code composer studio and reinstalled,,,, yet same response.
4. My reset pin automatically keep on Getting low for 20us . according to datasheet : " Device Reset (in) and Watchdog Reset (out).
Device reset. XRS causes the device to
terminate execution. The PC will point to the
address contained at the location 0x3FFFC0.
When XRS is brought to a high level,
execution begins at the location pointed to by
the PC. This pin is driven low by the DSP when a watchdog reset occurs. During
watchdog reset, the XRS pin will be driven low
for the watchdog reset duration of
512 XCLKIN cycles.
The output buffer of this pin is an open-drain
with an internal pullup (100 µA, typical). It is
recommended that this pin be driven by an
open-drain device. "
I think watchdog timer keeps on resetting , hence this pin goes low for periodically . ........ if my thinking is correct please tell me how to stop the WATCHDOG TIMER before start programming the target ..
and my one more doubt is " May be for processor failure this response is showing " Please Kindly help me to solve this issue ..
Many Thanks,
