ANSWERED impact program failing

[superben51]

i'm trying to program my coolrunner with a lpt cable but when i click program impact returns the following error (this is with verify deselected in the program settings)
INFO:iMPACT:1982 - '1'one bit could not be programmed correctly.

with verify selected it returns

'1': Programming device...
done.
'1': Verifying device...
'1': Verification terminated due to errors
'1': Failed at address 0.
'1': Programming of user selected options failed.

the green light on the coolrunner is still solid so it is not programed yet

is it a home made cable or bought?

Just try with 360gcprog. It's much simple and stress free. Although if your cable is not properly made or is too long you most likely won't be able to program anything

i tried 360gcprog but it says my TDO is stuck at one? any idea what that means?

You have a problem on your cable. Either the connections or its length.
Make sure you have all the connections right. Test them with a multimeter. If they are all ok then your problem must be the length of the cable.
what's its length?
what guide you follow to build the cable?
What are you using to power the CoolRunner? some king of CK3 or the motherboard?

i'm using two AA batteries to power it and my lentgh in about 3cm per wire i used the variation of gilil's cable with out any dioides or resistors. what would i be looking for with a multimeter?

 

[superben51]

okay so i played around with it some more and then i stared to get this error message

initialixing parallel port at 0x378
IR length: 8
warning TDO seems to be stuck at 1
unable to detect JTAG chain length

any idea what it means?

Is this a LPT Cable or Homemade?
