Jul 06 08:36:40 <jzaw_pl> https://blog.dzki.co.uk/?p=199 needs tidying up a bit ... any comments or questions ?
Jul 06 21:27:01 <MostAwesomeDude> Good afternoon. I'm having a delightfully unfun time trying to JTAG my GuruPlug. Has anybody successfully done it?
Jul 06 21:31:09 <MostAwesomeDude> I'm currently blocked on a surfeit of extra idcodes on the JTAG interface.
Jul 06 21:32:22 * roxfan looks up "surfeit"
Jul 06 21:32:44 <roxfan> still learn a new word everyday on irc
Jul 06 21:33:20 <roxfan> what do you mean by "extra" idcodes?
Jul 06 21:33:57 <MostAwesomeDude> Warn : Unexpected idcode after end of chain: 608 0x0000007f
Jul 06 21:34:05 <MostAwesomeDude> A couple dozen of those.
Jul 06 21:34:08 <roxfan> hmm that doesn't look right
Jul 06 21:34:30 <MostAwesomeDude> I'm using the sheeva files, since everybody indicates they work with guru.
Jul 06 21:35:03 <roxfan> maybe they changed something in the scan chain...
Jul 06 21:35:15 <roxfan> don't have guruplug so can't really help
Jul 06 21:35:19 <MostAwesomeDude> Ah.
Jul 06 21:35:27 <roxfan> is the first id looking okay?
Jul 06 21:35:51 <MostAwesomeDude> Yeah. I just disabled the chain length sanity check, and now it's found the EICE.
Jul 06 21:35:57 <MostAwesomeDude> Error: unexpected Feroceon EICE version signature
Jul 06 21:36:02 <MostAwesomeDude> Hilarious. But not fatal.
Jul 06 21:36:14 <PhotoJim> surfeit?  plethora!
Jul 06 21:37:16 <MostAwesomeDude> Hey, telnet'd in. Now I've just gotta remember how to use this dang thing.
Jul 06 21:39:09 <roxfan> too late, you're already using it
Jul 06 21:43:12 <MostAwesomeDude> Haha, got the NAND all set up.
Jul 06 21:43:13 <comradekingu> MostAwesomeDude: You should have ssh'd in, otherwise Prince will be all over your internets, and when prince is in ur internetz, its all over.
Jul 06 21:43:42 <MostAwesomeDude> comradekingu: It's okay, I have numbers in my head, so I'm protected.
Jul 06 21:43:58 <comradekingu> I think its already over
Jul 06 21:45:15 <MostAwesomeDude> Well, I can't seem to halt the board. Figures. :T
Jul 06 22:01:12 <MostAwesomeDude> So yeah. I have *zero* idea how to halt the board. Any help would be hot.
Jul 06 22:04:02 <PhotoJim> halt it how?  I don't think ht has an elegant hardware halt.  halt the OS, unplug.
Jul 06 22:05:29 <MostAwesomeDude> From JTAG. It's bricked, bad u-boot flash, I think.
Jul 06 22:06:33 <MostAwesomeDude> I can see the CPU, but it won't halt and so I can't do anything useful.
Jul 06 22:09:28 <MostAwesomeDude> IIUC the SoC just jumps to the beginning of NAND, right?
Jul 06 22:13:04 <MostAwesomeDude> Right, then. I'm just gonna chill for a bit and wait.
Jul 07 00:31:46 <bkero> MostAwesomeDude: I've jtagged mine
Jul 07 00:31:59 <bkero> MostAwesomeDude: guru has a different machine ID than the guru.
Jul 07 00:59:14 <bkero> MostAwesomeDude: I used to have a proper jtag file, the jtag app for flashing u-boot is in Guruplug-installer.tar.gz
Jul 07 01:03:01 <MostAwesomeDude> bkero: Tried it, didn't work.
Jul 07 02:26:44 <MostAwesomeDude> bkero: http://paste.pocoo.org/show/234405/
Jul 07 02:26:52 <MostAwesomeDude> Look familiar? :3
