Other Parts Discussed in Thread: CCSTUDIO
Hi
Target C6455
Recently, we've been able to connect CCSv3.3 to our legacy product using an XDS510 emulator. But now, we get the error
Error connecting to the target:
Error 0x80000240/-1146
Fatal Error during: Initialization, OCS,
Invalid data was scanned by the emulation controller.
Verify the board setup to make sure the scan chain is properly
defined.
This is the same error we get from CCSv3.3 and CCSv4.2.4.00033
One theory is that the recent upgrade to CCSv4.2.3 has screwed up the driver configuration (we say this because we recall connecting prior to CCSv4.2.3)
We've used SdConfig.exe in the CCSv3.3 folder and SdConfigEx.exe in the CCSv4 folders below and the Emulator Test passes.
C:\CCStudio_v3.3\specdig\sdconfig
"C:\Program Files\Texas Instruments\ccsv4\emulation\specdig\sdconfigex\SdConfigEx.exe
** Emulator Test **
$$ EmuProductName=XDS510USB
$$ EmuPortAddr=0x510
$$ EmuPortMode=USB
$$ ProductId=510
$$ ProductVersion=84
** Emulator Scan Test
-- Found JTAG IR length of 6
-- Found 1 JTAG device(s) in the scan chain
So what can be the issue? Both CCS versions can't connect yet both SdConfig versions say "hey, no problem here".
This is a really urgent issue as we have legacy product that needs a bug fix!!!!!
Another data point is we have one PC that does not have CCSv4 installed and it can connect to the target.
We can however connect to an EVMC6455 board successfully using the XDS510. CCSv3 is happy with the EVM.
With the XDS510PLUS, the output when connected to our product is (both SdConfig and SdConfigEx give the same output)
** Emulator Test **
$$ EmuProductName=XDS510USB
$$ EmuPortAddr=0x510
$$ EmuPortMode=USB
$$ ProductId=510
$$ ProductVersion=86
** Emulator Scan Test
ERROR >> JTAG IR scan test failed
>> Check power to your emulator/eZdsp
>> Then check your port mode/address
Pretty strange eh. The XDS510 can find the scan chain devices but the XDS510PLUS cannot.
Perhaps the difference between the XDS510 and XDS510PLUS can be explained by differences in signal levels or timing requirements?
But the perplexing thing is why can I connect the XDS510 to an EVM no problems, but not our product, yet SdConfig says "No hay problema".
I've tried several systems from my PC and same problem.
Cheers
