BSDL - file for the LPC2292 in JTAG chain

Started by xbedded April 26, 2007
Hi,

I have a jtag chain which includes tree CPLD and one LPC2292. I only
want to programm the CPLDs. The problem is, that I have to specify all
parts of the chain. So I needing a BSDL - file for the LPC2292. I
could not find any usefull information at the NXP webside.
I try to build tis file by my programming tool (Xilinx iMACT). It asks
about Instruction Register Lenght. I have tryed settings 1 to 9, but
it didn't work. I got the errormessage: "The idcode read from the
device does not match the idcode in the bsdl File".

Has anyone an idea?

There are no BSDL files for the LPC21/22xx, as they don't have boundary scan
functionality implemented. The JTAG interface is only used to access the
ARM7TDMI core.

The IR length is 4, the IDCODE should be 0x4f0f0f0f IIRC.

The IDCODE in your BSDL file (that you seem to say you created from
scratch) is incorrect?
