Dear All,
I have to implement the jtag and execute XSVF file through diagnostic
command from u-boot.
the layout of our board as below:
__________
|_Processor| -> FPGA -> CPLD----
^ |
|__________________________|
I can able to get Device ID of both FPGA and CPLD
but iam not able to execute XSVF file.
when i debuged the code i found that it is expecting data
from TDO line. but this is not happening.
My question is:
when i can able to get device id why can i execute the XSVF file
NOTE:
The state is moving As below
xsvfDoXREPEAT
xsvfDoXENDXR
xsvfDoXENDXR
xsvfDoXSTATE
xsvfDoXSTATE
xsvfDoXRUNTEST
xsvfDoXSIR
xsvfDoXSDRSIZE
xsvfDoXSDRSIZE
xsvfDoXTDOMASK
xsvfDoXSDRTDO
TAP State = DRUPDATE
TAP State = RUNTEST/IDLE
TDO Expected = 0xf4004093
TDO Captured =
TDO Mask = 0x0fffffff
xsvfDoXSDRTDO iErrorCode
ERROR: TDO mismatch
ERROR at or near XSVF command #10.See line #10 in the XSVF ASCII file.
Upgarde the Image and RESTART !!!
Regards
Manukumar
