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 !!!
