[00:24:11] <jepler> oh I forget, even though pi2/3 can run unmodified debian armhf userspace, "raspbian" still has a lot of traction and an incompatible ABI. That's unfortunate.

[14:21:50] <jepler> tinkerer: in uspace realtime, it runs most of the time without root access to the filesystem, including /dev.
[14:22:08] <jepler> tinkerer: the way to temporarily access the filesystem as root is unfortunately not exposed in the RTAPI "C" API
[14:23:21] <jepler> the way this is accomplished is in rtapi_uspace.hh, class WithRoot
[14:23:26] <jepler> WithRoot() { if(!level) setfsuid(geteuid()); level++; }
[14:23:26] <jepler> ~WithRoot() { --level; if(!level) setfsuid(getuid()); }
[14:26:49] <jepler> so untested, you could implement rtapi_open_as_root in "C" as
[14:26:50] <jepler> int rtapi_open_as_root(const char *filename, int mode) {
[14:26:51] <jepler> setfsuid(geteuid());
[14:26:51] <jepler> int r = open(filename, mode);
[14:26:51] <jepler> setfsuid(getuid());
[14:26:53] <jepler> return r;

[21:10:28] <tinkerer> is pcw around?
[21:10:54] <tinkerer> or jepler?
[21:34:14] <tinkerer> where can I found the 7I90HDIO.PIN file.
[21:41:02] <tinkerer> err: find
[21:42:34] -!- skunkworks_ has quit [Ping timeout: 240 seconds]
[21:46:21] <jepler> http://mesanet.com/software/parallel/7i90.zip has the files that mesa ships for the 7i90 card. I don't know if any of them are called "7I90HDIO".
[21:47:44] <jepler> looks like linuxcnc.org doesn't ship any firmwares for the 7i90
[21:48:43] <jepler> usually it's the .bit file you're interested in, you can run mesaflash to get the .pin file which is just metadata, or read it out when starting linuxcnc
[21:49:10] <jepler> (of course you may not be able to do that with mesaflash since like hm2_spi in linuxcnc, it uses /dev/spidev for access to the card)
[21:49:20] -!- chillly has quit []
[21:52:10] <tinkerer> no the PIN file describe more then the firmware pins
[21:52:33] <tinkerer> for instance the usr leds

[21:53:55] <tinkerer> because I have big troubles with the card
[21:54:39] <tinkerer> the outputs suddenly stops working
[21:56:46] <tinkerer> I can communicate with the card and step around with axis but just virtual. the outputs of the card are staying high.
[21:56:59] <tinkerer> very strange
[21:57:45] <tinkerer> so I will try to debug with the leds
[21:57:46] <pcw_home> all I/Os high suggests that the watchdog has bitten
[21:58:05] <tinkerer> suddenly
[21:59:37] <tinkerer> it works the half night without any problems
[22:00:52] <tinkerer> I have to configurations on different raspis. one with machinekit and one with lcnc
[22:02:10] <tinkerer> the machinekit config has been unchanged since 2 days
[22:03:45] <tinkerer> and nevertheless the card stops working here too
[22:04:45] <tinkerer> so, when bites the watchdog?
[22:06:08] <tinkerer> or how can I serve the watchdog
[22:06:22] <tinkerer> or feed :)
[22:07:30] <tinkerer> pcw: can you tell me the pins of the usr leds?
[22:09:31] <tinkerer> suddenly lacks a "?"
[22:12:20] <tinkerer> jepler: it's not in the 7i90.zip
[22:13:42] <tinkerer> btw: I got some strange messages from lcnc " libGL error: failed to open drm device: No such file or directory
[22:13:42] <tinkerer> libGL error: failed to load driver: i965
[22:13:42] <tinkerer> "
[22:36:43] <cradek> that's not a linuxcnc error. try running any other opengl program.
[22:41:48] <tinkerer> ah ok
[22:42:31] <tinkerer> strange i965 on arm
[22:45:03] <tinkerer> pcw or jepler: no clues? I cant found any examples in the source for petting the watchdog
[22:45:25] <tinkerer> arg... find
[22:47:02] <jepler> it happens automatically as part of the "write" function
[22:47:40] <tinkerer> True if the watchdog has bit, False if the watchdog has not bit. If the watchdog has bit and the has_bit bit is True, the user can reset it to False to resume operation.
[22:49:44] <tinkerer> so I would like connect the has_bit pin to the usr led for checking if the wd has bit.
[22:50:32] <tinkerer> but I dont know name or number of the led pin
[22:54:51] <cradek> if the watchdog bites I think you can't control the LEDs on the board anymore - along with all IO they do a predefined thing
[22:56:13] <cradek> see the Watchdog section in the hostmot2 manpage
[22:57:14] <pcw_home> you can control the LEDs (they are not like the GPIO pins that are all floated on WD bite)
[22:57:29] <cradek> oh!
[22:57:46] <cradek> heh reading the manpage is still good advice even though I'm wrong, right?
[22:57:49] <tinkerer> yes I have assumed this
[22:58:18] <tinkerer> cradek: what does thet mean?
[22:58:22] <tinkerer> that
[22:58:28] -!- Miner_48er has quit [Quit: Leaving]
[22:58:35] <cradek> what?
[22:59:13] <pcw_home> The hal LED pins will be CR01,CR02,CR03 and CR04
[23:00:35] <tinkerer> I have read the manpage!
[23:03:19] <tinkerer> usr1 = cr03 & usr0 = cr04 ?
[23:06:01] <pcw_home> Oh yeah I forgot, the 7I90 only has 2 user LEDS so they will be named CR01 and CR02 in hal
[23:07:13] <tinkerer> ah, its labeled on the board: cr04 and cr05
[23:07:38] <tinkerer> thanks
[23:08:08] <pcw_home> Yeah theres no correspondence between silk screen art and hal names for user LEDs
[23:09:38] <tinkerer> I assume the gpios are disabled through the drivers (pi5c 16211a)?
[23:11:57] <tinkerer> silk screen art :D
[23:19:57] <tinkerer> The pins are numbered from CR01 upwards with the name corresponding to the PCB silkscreen.
[23:20:06] <tinkerer> :)
[23:20:41] <tinkerer> but: hm2-stepper-7i90.hal:64: Pin 'hm2_7i90.0.CR01' does not exist
[23:31:43] <pcw_home> The GPIOs are disabled by setting all DDRs to 0

[23:34:40] -!- kingarmadillo has quit [Ping timeout: 252 seconds]
[23:34:45] <tinkerer> the led pin surprisingly the word led in the bin name... ;)
[23:34:54] <tinkerer> has
[23:45:11] <tinkerer> a slightly weired question: does the card store/remember the has_bit value for a certain time? despite disconnecting the card from power?
[23:53:37] <tinkerer> :D after putting the following line in the hal file the watchdog never bites: setp hm2_[HOSTMOT2](BOARD).0.watchdog.has_bit FALSE
[23:53:42] <tinkerer> very funny
