SP605 can't be programming through JTAG

yhwu · ‎05-08-2012

I bought two SP605 Evaluation kit boards last week. One board can’t be downloaded bit file through JTAG(min-USB on board) and the other is ok.

Here is the error message.

ERROR:iMPACT - A problem may exist in the hardware configuration. Check that the cable, scan chain, and power connections are intact, that the specified scan chain configuration matches the actual hardware, and that the power supply is adequate and delivering the correct voltage.

PROGRESS_END - End Operation.

Elapsed time = 0 sec.

when assign a bit file:

INFO:iMPACT - Current time: 5/17/2012 3:10:47 PM PROGRESS_START - Starting Operation. INFO:iMPACT:583 - '2': The idcode read from the device does not match the idcode in the bsdl File. INFO:iMPACT:1578 - '2': Device IDCODE : 00001111111111111111111111111111 INFO:iMPACT:1579 - '2': Expected IDCODE: 00000100000000101000000010010011 PROGRESS_END - End Operation. Elapsed time = 0 sec.

What could the problem be? Thanks.

ERROR BOARD S/N: 1150-9603

GOOD BOARD S/N: 1150-9221

BTW, Both are fine when testing through UART(min-USB on board) . Thank you.

Have you compared position of jumper J19 between the good board and the problem board?

yes, all jumpers and switchs of the two board have the same status.

Please check the status LEDs on both boards - in particular those for the power supplies. Are they all lit on the "problematic" board as they should be?
