q1:
Is the device id the same to the Jtag id displayed when programming the fpgas with the .sof file ?
q2:
Where could i find all the altera fpga jtag ids ?
Could anybody help me with this two question? thank you!
-----------------------------------------------------------------
thank you ,nekojiru, i found that txt file, i really helps.
But my ture problem is something is wrong with the jtag programming:
When i proram a FPGA EP3CLS200F484ES with a EP3CLS200F484ES sof file with jtag , a error occur :
Expected JTAG ID code 0X027020DD for device 1, but found JTAG ID code 0x00000000.
Then i program the same FPGA with a EP3C120F484 sof file with jtag , a error occur :
Expected JTAG ID code 0X020F70DD for device 1, but found JTAG ID code 0X027020DD.
The two errors really cnfused me, for the first error, it seems that the jtag chain can not get the right ID code, but for the sceond one, the jtag does get the right ID code.
q3.
How to explain this situation?
When using the "auto detect" in the programmer , jtag can recognize the FPGA as EP3CLS200F484.
q4.
Does it prove that the jtag chain is good and correct?
I hope someone could help me, thank you.
