Did the same commands as listed in previous email, this time from a Raspberry PI running Debian.
The modules in this version of openocd on the RPI must be improved. Instead of a segment fault result running openocd from a Dell laptop with Debian Squeeze this run came back with a more appropriate message. I am wondering if the replacement of the small Alkaline button battery (the old one was leaking) has anything to do with the problems experienced with even seeing the JTAG port on the SheevaPlug??? root@raspberrypi:/home/pi# openocd -s /usr/share/openocd/scripts/ -f interface/sheevaplug.cfg -f board/sheevaplug.cfg -c init Open On-Chip Debugger 0.5.0 (2012-05-23-17:50) Licensed under GNU GPL v2 For bug reports, read http://openocd.berlios.de/doc/doxygen/bugs.html Info : only one transport option; autoselect 'jtag' 2000 kHz Warn : Interface already configured, ignoring Error: already specified ft2232_layout sheevaplug 2000 kHz trst_and_srst separate srst_gates_jtag trst_push_pull srst_open_drain adapter_nsrst_delay: 200 jtag_ntrst_delay: 200 dcc downloads are enabled Warn : use 'feroceon.cpu' as target identifier, not '0' sheevaplug_load_uboot Error: unable to open ftdi device: device not found in procedure 'init' ----- Original Message ----- From: DrEagle <drea...@doukki.net> To: Herman Swartz <herman_swa...@yahoo.com> Cc: "debian-arm@lists.debian.org" <debian-arm@lists.debian.org> Sent: Monday, December 3, 2012 1:19 PM Subject: Re: Bricked Sheevaplug Sorry for the delay, I just come back home !
