Hi, I was recently given some dev boards with LPC2468FBD208. When trying to use Segger's JLink to program the chip, I get the following error:
Connecting ...
- Connecting via USB to J-Link device 0
- J-Link firmware: J-Link ARM V8 compiled Nov 28 2014 13:44:46
- Device "LPC2468" selected.
- Target interface speed: 4000 kHz (Fixed)
- VTarget = 3.345V
- TotalIRLen = 3, IRPrint = 0x01
- JTAG chain detection found 1 devices:

- TotalIRLen = 3, IRPrint = 0x01
- JTAG chain detection found 1 devices:
- #0 Id: 0x901F002B, IRLen: 03, Unknown device
- ERROR: CPU-TAP not found in JTAG chain
- ERROR: Failed to connect.
Could not establish a connection to target.
Which is weird. I did a search for 0x901F002B, but I could not find any information. However when looking at existing BSDLs online for LPC2468, They list 0x401F002B as a valid IDCODE.
I also gave OpenOCD a try with using the IDCODE, but I'm getting an error about EmbeddedICE being the wrong version (Note that I've set IRLen to 4 instaed of 3 as 3 produces inconsistant EmbeddedICE comms ctrl value).

Any help is appreciated.
Thank you.
