Hi Sarah, that pretty much correct. One interesting side thing is that sometimes the olimex jtag programmer is unable to provide enough power to the 2148 board, and you run into flashing problems. You can avoid this by using a 9VDC wall wart. My hypothesis is that this stems from the lack of current sourcing abilities of some laptops (mainly my laptop), so it may also be mitigated by using a powered hub.
Hope that's of some assistance... -dave On Thu, Jan 29, 2009 at 6:36 AM, Sarah A Sharp <saharabe...@gmail.com> wrote: > Hi Kay, > > Do these directions look right for the cabling/jumper setup for the > LPC2148 board and Olimex OCD JTAG programmer?
