[19:45:49] <pcw_home> Thats pretty strange (same bitfile) could be a hm2_eth bug

[19:49:27] -!- Tom_itx [Tom_itx!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc-devel
[19:51:22] <asah> right. I am using the same hal stuff.
[19:51:34] <asah> just changing to hm2_eth
[19:51:35] <asah> etc.
[19:55:05] <pcw_home> This is probably the first time the TPPWM has been tested with hm2_eth
[19:56:09] <pcw_home> does the log say anything interesting? (no dmesg anymore)
[19:56:59] <asah> how do I access log?
[20:00:17] <asah> syslog?
[20:01:06] <asah> “unexpected realtime delay on RT thread 1"
[20:02:19] <pcw_home> var/log/linuxcnc.log
[20:02:42] <pcw_home> what servo thread rate
[20:02:47] <pcw_home> ?
[20:03:35] <pcw_home> you have to enable logging in UBC (theres a script)
[20:04:26] <asah> 1khz
[20:04:34] <asah> not enabled logging
[20:04:40] <asah> in ubc rather
[20:06:12] <pcw_home> 1 KHz should be fine but you have to make sure the interface you are using can have no other traffic/attemped traffic
[20:06:31] <asah> should be only for this
[20:06:55] <pcw_home> manual config IPV4 only
[20:07:03] <asah> right
[20:07:45] <asah> looks like gpio pin 20 (labeled as PWM enable) is false
[20:08:02] <asah> hm2_7i80.0.gpio.020.in
[20:08:26] <pcw_home> thats correct if enabled (active low enables)
[20:08:34] <asah> ok
[20:08:49] <pcw_home> no PWM?
[20:09:21] <pcw_home> maybe the log can shed some light
[20:09:52] <asah> getting pretty high phase-error-us, lots of jitter in that signal.
[20:10:01] <asah> but no pwm
[20:11:06] <pcw_home> Yes the Ethernet jitter (and preemt-rt jitter) is much worse but the DPLL shoud be able to improve that a lot
[20:11:32] <asah> ok, but PWM should still work
[20:11:37] <asah> regardless
[20:11:41] <pcw_home> Yes
[20:12:04] <pcw_home> I think the log needs to be read
[20:12:17] <asah> ok, the linuxcnc one or the ubc log?
[20:12:32] <pcw_home> linuxcnc.log
[20:12:37] <asah> ok.

[20:12:57] <asah> shows its discovered the device.
[20:13:04] <asah> shows all the pins
[20:13:12] <asah> Ill email it to you.
[20:13:16] <pcw_home> you may have to turn on debugging
[20:13:35] <pcw_home> so it found the TPPWMs?
[20:13:49] <asah> they show up as PWMGen:0
[20:13:56] <asah> 3-Phase PWMGen: 2
[20:14:00] <asah> clock_frequence.....
[20:16:08] <asah> in your inbox is a snippet of start to finish.
[20:16:28] <asah> I have debug_modules=1

[20:20:26] -!- syyl_ws has quit [Quit: Verlassend]
[20:20:59] <pcw_home> micges unfortunately its a 7i80hd-25 bitfile (And I dont think you have a -25)
[20:21:25] <asah> oscilliscope says no pwm coming out of motor UVW pins
[20:21:26] <micges> oh
[20:21:32] <micges> ok
[20:21:38] <pcw_home> but there should be other tppwm bitfiles, let me take a look
[20:21:41] <cradek> memleak: question about 3.4.55-rtai-2: every time I type a key or move the mouse (both keyboard and mouse are ps2 type) I get several lines in the system log that look like: evbug: Event. Dev: input0, Type: 1, Code: 28, Value: 1
[20:21:49] <cradek> well that wasn't a question
[20:21:54] <cradek> the question is do you know how to make it stop?
[20:22:06] <asah> what does tp mean in tppwm ?
[20:22:22] <pcw_home> three phase
[20:22:29] <asah> right.
[20:22:32] <asah> =)
[20:23:20] <pcw_home> micges: 7i80hd_16_svsttp6_6_7i39.bit should do to test
[20:23:29] <micges> but besides jitter tppwm should work like in hm2_pci
[20:24:09] <micges> ok
[20:25:38] <pcw_home> You should be able to check if the tppwms outputs are working fairly easily
[20:26:51] <asah> I do get a couble of messages right when I halrun: rtapi:0 stopped msgd:0 stopped
[20:27:00] <asah> but ssi feedback works fine
[20:27:37] <pcw_home> (watch the correct GPIO bit)
[20:27:39] <pcw_home> If enabled (and default 0 input) the associated GPIO pins should be randomly high/low
[20:28:18] <asah> so in this case gpio pin 21?
[20:28:36] <pcw_home> (random sampling of high frequency 50% duty cycle signal at servo thread rate)
[20:28:50] <micges> ok
[20:28:59] <pcw_home> yeah any the A,B,C outputs
[20:31:14] -!- larryone has quit [Quit: This computer has gone to sleep]
[20:33:13] <asah> show pin hm2_7i80.0.gpio.021 always is false
[20:34:24] <asah> same with 022, and 023
[20:37:19] <asah> is the ubc logging thing a linuxcnc thing or a kernel dev thing?
[20:39:08] <pcw_home> dont know, never used it
[20:39:23] <pcw_home> is the channel 0 or 1
[20:39:29] <pcw_home> is this
[20:39:34] <asah> I am using channel 1

[20:41:03] <pcw_home> when you have linuxcnc running can you read hm2 register 0x4604?
[20:41:04] <pcw_home> (I think mesaflash can do that)
[20:42:03] <asah> —rpo ?
[20:43:39] -!- sumpfralle has quit [Client Quit]
[20:44:59] <asah> if I do it while its running I get no 7i80 board found
[20:45:21] <pcw_home> it should work
[20:45:25] <asah> mesaflash —device 7i80 —addr 192.168.1.121 —rpo 0x4604
[20:47:19] <asah> when its not running, result is FFFFFFFD
[20:47:27] <asah> (when linuxcnc is not running)
[20:48:27] <pcw_home> weird linuxcnc running or not should make no difference
[20:48:48] -!- larryone has quit [Read error: Connection reset by peer]
[20:50:39] <asah> seems to.
[20:50:42] <asah> def repeatable
[20:52:03] <pcw_home> can you ping the 7i80 with linuxcnc running?
[20:52:24] <asah> yes
[20:53:36] <pcw_home> Hmm maybe something in mesaflash changed
[20:54:24] <micges> I don't think so
[20:54:26] <asah> is there another way to read that reg
[20:54:27] <asah> ?
[20:54:49] <pcw_home> not sure how mesaflash could even detect that another device was accessing the 7I80
[20:56:15] <pcw_home> anyway looks like the tppwm is enabled (LSB is '1')
[20:57:26] <asah> pretty weird.
[20:57:51] <pcw_home> I would like to look at 0x1104 but its likely cleared by linuxcnc as it exits (and by the watchdog)
[20:58:22] <pcw_home> I would try reading 0x1104 in linuxcnc (via raw-read)
[20:59:49] -!- thomaslindstr_m has quit [Ping timeout: 252 seconds]
[21:00:11] <asah> ok, have raw mode enabled.
[21:00:52] <asah> like dump_state ?
[21:01:41] <pcw_home> see raw_mode in the hostmot2 man page
[21:01:45] <asah> setp raw.read_address 0x1104
[21:02:04] -!- tlab has quit [Ping timeout: 258 seconds]
[21:03:16] <pcw_home> then just show/watch the read_data pin
[21:03:33] -!- larryone1 has quit [Quit: This computer has gone to sleep]
[21:03:46] <pcw_home> and hope its not in decimal
[21:03:57] <asah> all zeros
[21:04:25] <pcw_home> ok that would be why PWM does not work
[21:04:57] <cradek> memleak: [blacklist evbug fixes it]
[21:05:11] <cradek> I don't know what evbug's supposed to be
[21:05:14] <pcw_home> well wait a second the SSI cannot work with all 0 DDR
[21:05:30] <asah> pcw_home: how to fix?
[21:05:37] <asah> SSI def working
[21:05:54] <pcw_home> still?
[21:05:57] <asah> yes
[21:06:13] <asah> just checked 0x4604 and got FFFFFFFD
[21:06:22] <asah> so I think my process is correct
[21:06:27] <asah> for reading registers
[21:06:39] <pcw_home> try 0x0100
[21:07:06] <asah> 55AACAFE
[21:08:09] <micges> pcw_home: here I can access 7i80 by mf while lcnc is running, like I always could
[21:10:08] <pcw_home> well 0x1104 cannot be all 0s and have ssi working (no outputs would work)
[21:10:23] <pcw_home> so something is funny
[21:10:31] <cradek> seb_kuzminsky: is it on purpose that there's no dists/wheezy/2.6 nonsim?
[21:10:37] <asah> should I reflash?
[21:11:09] <pcw_home> no
[21:11:30] <pcw_home> bitfiles are CRC checked by the FPGA
[21:11:39] <asah> ok.
[21:12:49] -!- Deejay has quit [Quit: bye]
[21:13:43] <pcw_home> sorry not 0x1104 but 0x1100
[21:14:32] <pcw_home> (got confused by TPPWMGEN1 vs IOport 0)
[21:14:58] <pcw_home> 0x00000000 is correct to 0x1104 (second connector)
[21:16:06] <asah> 00F40F40
[21:16:26] <asah> ah. right. nope first connector

[21:36:50] <memleak> evbug i would assume would be either xf86-input-evdev or CONFIG_INPUT_EVDEV in kernel
[21:37:00] <memleak> not sure which one it correlates to
[21:37:14] <pcw_home> might be a hm2_eth driver bug and might be a firmware bug
[21:37:15] <pcw_home> The DDR and tppwm enable seem correct, you might try writing
[21:37:17] <pcw_home> 0x20080200 to 0x4504 (set all PWMs on channel 1 to 50%)
[21:38:42] -!- sumpfralle has quit [Ping timeout: 245 seconds]
[21:41:34] <asah> no effect
[21:42:38] <asah> if I read the data back from 0x4504 I get FFFFFFFF
[21:43:16] <memleak> PS/2 devices in X use the xf86-input-mouse and xf86-input-keyboard drivers i believe, so as far as evdev goes... thats actually really strange.. it should be using the CONFIG_KEYBOARD_ATKBD (AT style keyboard driver) and or CONFIG_SERIO_I8042 (standard AT style keyboard driver / PS/2 serial driver)

[21:44:50] <memleak> looking at kernel kconfig, CONFIG_KEYBOARD_ATKBD automatically selects CONFIG_SERIO_I8042 so they work hand-in-hand, evdev / evbug doesnt make sense to me..
[21:45:16] <memleak> unless ATKBD / I8042 use evbug.. i have no idea actually. i never use PS/2

[22:52:44] <cradek> I'm trying to use pncconf to set up the 5i25 to run my previously-parport-driven mill
[22:53:12] <cradek> pncconf seems like it detected the 5i25
[22:53:24] <cradek> but none of the "firmware" choices match the label on mine
[22:53:41] <cradek> I actually just want to have it in the smart parport mode
[22:54:21] <cradek> aha looks like I want prob_rfx2
[22:55:51] <cradek> I'm not seeing 5i25 firmwares in http://linuxcnc.org/dists/wheezy/base/binary-all/
[22:56:33] <cradek> (my label says 7i74x2.bit -- but I don't have any of those)
[22:57:25] <micges> 5i25 have bitfile in flash onboard
[22:57:50] <cradek> but I need to change it
[22:58:03] <micges> use mesaflash for it
[22:58:05] <cradek> I thought we were going to package up the fimware choices and the flashing utility
[22:58:28] <cradek> mesaflash didn't install as part of 2.6
[22:58:42] <cradek> is there still packaging work to be done?
[22:58:52] <micges> yes we are
[22:59:10] <micges> mesaflash isn't ready yet
[22:59:15] <cradek> ah ok
[22:59:19] <cradek> can I help?
[23:00:13] <micges> not really, few bugs locally and seb created /debian fix for me
[23:00:49] <cradek> I can at least help test then, when you are ready - I now have a wheezy+rtai machine for testing 5i25/pncconf/2.6

[23:22:59] <memleak> micges, hostmot2? perfect! i have a question for you! what firmware files are required by mesaflash / pncconf for the FPGA? is it the .xml .pin or ?
[23:23:29] <memleak> and as for the location of the files, do they go in /lib/firmware/hm2 specifically?
[23:24:07] <micges> yes they all should go there
[23:24:42] <micges> mesaflash use only bit files (firmware) and can generate pin file (firmware info)
[23:24:59] <micges> pncconf use xml files
[23:25:16] <memleak> ok so everything not just bit goes in /lib/firmware/hm2
[23:25:38] <memleak> is it /lib/firmware/hm2/<your FPGA> or do they just float loosely in hm2 directory?
[23:26:02] <memleak> i.e. /lib/firmware/hm2/5i25/
[23:26:10] <micges> each board have subdir
[23:26:37] <memleak> ok great thanks!
[23:27:14] <memleak> so the .pin files aren't really used for anything?
[23:27:39] <memleak> if bit is the actual firmware binary and pncconf use xmls..
[23:28:15] -!- larryone has quit [Client Quit]
