[01e6a05] | 16 | Eric Norum (eric@@skatter.usask.ca) has a driver for a parallel |
---|
| 17 | port interface to a BDM module. This driver has a long history |
---|
[3b568bd] | 18 | and is based on a driver by Gunter Magin (magin@@skil.camelot.de) |
---|
[01e6a05] | 19 | which in turn was based on BD32 for DOS by Scott Howard. Eric Norum |
---|
| 20 | and Chris Johns (ccj@@acm.org) have put together a package containing |
---|
| 21 | everything you need to use this BDM driver including software, PCB layouts, |
---|
| 22 | and machining drawings. From the README: |
---|
| 23 | |
---|
| 24 | "This package contains everything you need to be able to run GDB on |
---|
[b44cfb98] | 25 | Linux and control a Motorola CPU32+ (68360) or Coldfire (5206, 5206e, or |
---|
[01e6a05] | 26 | 5207) target through a standard PC parallel port." |
---|
| 27 | |
---|
| 28 | Information on this BDM driver is available at the following URL: |

[70b8f3ed] | 80 | Christian Haan <chn@@intego.de> has written a driver for FreeBSD |
---|
| 81 | based for"a slightly changed ICD BDM module (because of changes |
---|
| 82 | in the BDM interface on the PowerPC)" that "probably will work with |
---|
| 83 | the PD module too." His work is based on the M68K BDM work by |
---|
| 84 | Gunter Magin (Gunter.Magin@@skil.camelot.de) and |
---|
| 85 | the PPC BDM for Linux work by Sergey Drazhnikov (swd@@agua.comptek.ru). |

---|
| 94 | |
---|
| 95 | GDB includes support for a set of primitives to support the Macraigor |
---|
| 96 | Wiggler (OCD BDM). Unfortunately, this requires the use of a |
---|
| 97 | proprietary interface and is supported only on Windows. This forces |
---|
| 98 | one to use CYGWIN. Reports are that this results in a slow |
---|
| 99 | interface. Scott Howard (http://www.objsw.com) has announced |
---|
| 100 | that support for the gdb+wiggler combination under DJGPP which should |
---|
| 101 | run significantly faster. |
