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 |
---|
18 | and is based on a driver by Gunter Magin (magin@@skil.camelot.de) |
---|
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 |
---|
25 | Linux and control a Motorola CPU32+ (68360) or Coldfire (5206, 5206e, or |
---|
26 | 5207) target through a standard PC parallel port." |
---|
27 | |
---|
28 | Information on this BDM driver is available at the following URL: |
---|

---|

---|
32 | @end example |
---|
33 | |
---|
34 | The package is officially hosted at Eric Norum's ftp site: |
---|

40 | Peter Shoebridge (peter@@zeecube.com) has ported the Linux |
---|
41 | parallel port BDM driver from Eric Norum to Windows NT. It is |
---|
42 | available at http://www.zeecube.com/bdm. |
---|
43 | |
---|
44 | The efi332 project has a home-built BDM module and gdb backend for |
---|
45 | Linux. See http://efi332.eng.ohio-state.edu/efi332/hardware.html) |
---|
46 | for details. The device driver and gdb backend are based on those |
---|
47 | by Gunter Magin (magin@@skil.camelot.de) available from |
---|
48 | ftp.lpr.e-technik.tu-muenchen.de. |

83 | Christian Haan <chn@@intego.de> has written a driver for FreeBSD |

84 | based for"a slightly changed ICD BDM module (because of changes |

85 | in the BDM interface on the PowerPC)" that "probably will work with |
---|
86 | the PD module too." His work is based on the M68K BDM work by |
---|
87 | Gunter Magin (Gunter.Magin@@skil.camelot.de) and |
---|
88 | the PPC BDM for Linux work by Sergey Drazhnikov (swd@@agua.comptek.ru). |

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