Hi All
We have T1042 processor , currently we have populated the resistor ,capacitor and IC related to only power supply & JTAG . We are able to power it on but when on connecting JTAG with code warrior we are facing issue
Jtag leds are ok but configuration are not ok . Moment we are running code program with code warrior .We get the error
Error launching t1042-core 00_SRAM _T1042_Connect
CCSProtocolPlugin: Failed to correctly configure the JTAG chain
On hardware level we have checked
1. Power supply working
2. jtag reset is working
3. Jtag connection are varified
Kindly provide the answer for the same .
Thanks
Hi
Based on hardware design against AN4825 changes are made but still no success. .
Please find the attached RCW.txt file
Hardcoded RCW is 0x9E wrt RCW value are changed (only jtag configuration settings changed)
We are trying to detect processor in the JTAG chain
Also attached the scanboard command screenshot, not able to detected processor IDcode .
Hi
More to add on
On our processor we have mounted only power supply related components (IC, resistor ,etc) which is working.
JTAG related components also mounted on the hardware (Hardcoded RCW is 0x9E)
Now when we are running code warrior projects through SRAM (since DDR is not mounted on Hardware), we are getting Pop up ERROR " FAILED to configure JTAG chain "
RCW file have attached in my earlier post & made changes for JTAG. i.e. 0x9E
Is it ok to keep the RCW default values for other peripherals since on the board other than JTAG there is nothing else mounted.
Hi @utkarsh
Can you please provide your schematic here for further debugging. If not please create new technical case using below link.
I would also recommend you that in order to follow this request,
please do not forget to mention on the case description this case number
which is: # 00566644
Thanks

Hi @utkarsh
It seems that there is no valid RCW on the target board.
Please refer to "Table 4-12. Hard-Coded RCW Options" in T1042 Reference Manual to configure the your custom board as hard-coded RCW.
Thanks

Hi Khusbur
Further investigation, I found something weird.
On giving CCS command
source IPCODE.tcl or scanboard
It did not received the JTAG IDCode .Looks like processor itself didn't recognized.
Does it still required RCW configuration,since the processor itself not recognized.
Where all areas I can look ??
Kindly suggest
