I'm running a TMS320F28335 on a custom board as part of an inverter. The software is a non-bios project. The PWM of the inverter is working. Now I tried to add adc-Measurements, but the software ends up in "interrupt void ILLEGAL_ISR(void) // Illegal operation TRAP". Unfortunately, a while after that, the processor looses its connection and is gone - the connection can't be re-established anymore.
I operated the processor on the Eval-Kit Docking station with the XDS100 USB Emulator.
The error message was:
Can't Run Target CPU:Error 0x20000020/-1156 Severe Error during: Execution, Lost processor clock. Device may be operatin in a low-power mode. Do you want to bring it out of this mode?
Cant' Run Target CPU: Error 0x00000020/-2060 Error during: Execution, Processor is already running at 0x00000000.
Failed to remove the debug state from the target before diconnecting. There may still be breakpoint opcodes embedded in programm memory.
Error connectiong to the target: Error 0x00001200/-1135 Error during: OCS, Target, Unrecoverable emulation error
After this errors the processor could not be connected again. I ruined two controlcards with this error. I attached the software to this post (attention, it could stop also other processors).
Can anybody explain me how it is possible to stop the processor from working with just some code copied together from TI example programs?
Looks I have the same problem from the start.
I can't get CCS connected to the F28335 via XDS100 USB Emulator...
In reply to Vasily Smirnov:
I have also found exactly same error on my tms320f28335, please make some help on this error.............
In reply to kalpesh patel:
Hi, in my case it was enough to get the control card out of the DIMM slot and insert it back. And it started working.
Today i have lost my second device with the same error............
error tells that your device is locked, even i haven't lock the device.
when i connect device by holding xrs pin to ground........ it will show error message like "ADC Calibration not complete, check if device is unlocked and recalibrate"
even i haven't stop the device erase process.
Please anyone give me some good suggestions to recover from the error.
Please provide some additional information:
In reply to Lori Heustess:
I am waiting for your valuable reply, Thanks.
One more point i forgot to mentions that is,
I am using texas instrument's xds100 JTAG emulator
I have provided all the required information, please make some sense on it.
Unfortunately it does sound like your device has the CSM locked. This can happen if the erase is interrupted, for example - in this case the password locations can be an unknown state.
Do you have a TI field rep that you can contact for a replacement device? If not then please contact firstname.lastname@example.org and they should be able to get you in contact with someone who can work with you to get a new device.
I also noticed the version of your CCS 4 is a bit old. There were some issues that have been fixed - if you would please download the latest version.
I too facing same sort of error that :
I can't get CCS connected to the F28035 via XDS100 USB Emulator...
Even I run DBJTAG, but it doesn't make any sense : error:
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.
Whether I need to go for replacement of Device ?
Need ur reply fast !!!!!!!!1
