Re: Coldfire Boards
I should have been more clear. These boards did come with BDM modules,
but my board came second hand from another developer who either lost it
or simply forgot to send it along (I'm hoping its the later). The board
I received was in a shoebox with a few papers, the mini-ITX baseboard,
and the Fire Engine itself and its power adapter. No cabling or the BDM
Woutcher (youpi) to my knowledge is using the latest BSP (and so am I
when I built my kernel and JFFS2 image), but he's also unwilling to
override dBUG so he's using u-boot 2 beta which seems to have issues
booting the kernel.
Our boards in general are from 2004-ish, and were acquired from
Freescale when we told them we wished to port Debian to Coldfire. We got
roughly a mix of boards if previous posts are correct, mine is a m5478 I
believe if I read the specs right. I can't say what anyone else got.
