Hello, has anyone ever got this combination work on a native Linux box? Their Windows (cygwin) stuff on the other hand works very nicely. I prepared an old Linux RedHat 9.0 (2.4.20 kernel) distribution (on the very same machine where the Windows version of ocdremote works perfectly), so that their proprietary driver "ravenpp" would compile. The kernel modul loads, but after I run: ocdremote -c MPC55x The HOST LED on the Raven turns on (while on the Windows version it remains off). No error messages until I try to connect with cross compiled GDB 5.x - worst case: instant crash> ppcAttach Error from postreset: JTAG Error > FromClientAttach: Socket operation on non-socket > select: Bad file descriptor > Shut down sockets.- "best case" no crash, but timeout and errors. I tried all parallel port modes (SPP, EPP, ECP, ECP+EPP) and several ocdremote versions (1.3, 2.0, 2.13, 3.0, 3.1, 3.2 + latest). Macraigor is informed, but at times they are slow with repsonses or I and my problem are not big enough of a market value to justify an answer. Thanks for any hint or comment, Bernd
Macraigor's GNU tools (ocdremote), OCDemon RAVEN & PowerPC target running on native Linux?

No comment about if it ever worked. Well, bad luck there... pity that they don't like open source and let me fix their Linux-support. Have a nice day, Bernd

Many other JTAG dongles already supported. I'm not sure about direct Linux support. Arie de Muynck

> Look for OpenOCD onhttp://openocd.berlios.de/web/, it is a hardwareThanks for the pointer. I'am already there, ordered some cheap Amontec equipment(recommended by oocd), and will definitely take a deeper look into OpenOCD (currently ARM only). As far as I can see its just the perfect framework to add PowerPC. Concerning Macraigor's Raven: It's unlikely that it will ever be supported by any open source projects: the used parallel port protocol is as proprietary as their CPLD design within the Raven. Considering that Amontec sells a much cheaper customizable parallelport dongle (Chameleon) and provides a documented design which supposedly even beats the Raven in terms of speed: Ravens just can't get less interesting for me.

We are using the FTDI 2232 USB interface and LMI ARM Cortex M3. JTAG is slow but SERIAL is fast (920K baud). We need a little bit more bandwidth, so looking into SPI (SCK, SDA). FTDI can JTAG or SPI at 5.6Mb/s, but M3 needs to divide it by 256. See: "jtag clock" thread.
