[00:04:17] <seb_kuzminsky> is there a branch somewhere i can pull into 2.6?
[00:05:06] <jepler> seb_kuzminsky: no because I suck
[00:05:14] <jepler> seb_kuzminsky: I'll whip one up; sorry to be wasting your time
[00:06:50] <CaptHindsight> do you guys want to start testing 3.14 RTAI?
[00:07:05] <jepler> seb_kuzminsky: I guess it didn't even apply to 2.6, did it
[00:07:20] <seb_kuzminsky> CaptHindsight: i'd love to, but i dont have the bandwidth at the moment :-(
[00:07:31] <CaptHindsight> no rush

[00:16:49] <jepler> seb_kuzminsky: the old version used top-level modules like 9054.vhd.in
[00:16:55] <jepler> seb_kuzminsky: those files didn't get updated
[00:17:14] <jepler> seb_kuzminsky: I'm rearranging it so that we can use the toplevel files like Top9054HostMot2.vhd that peter provides

[00:20:44] <PCW> I'm trying to fix all top level files so they have the @Card@ and @Pin@ options selected
[00:21:17] <jepler> PCW: yes, at least Top9054HostMot2.vhd had that
[00:21:38] <jepler> PCW: does having @Card@ work for you in xilinx without our build stuff?
[00:22:14] <PCW> Yes I use it (with a gnarly batch file)

[00:42:35] <jepler> since I can build not-from-clean I'll continue working on things before doing another push. but I think I have that error corrected.
[00:43:42] <PCW> I dont think that pinout file is anything but a test file (it does not work with any of our daughtercards for example)
[00:43:52] <jepler> PCW: oh really?
[00:44:18] <jepler> we build it for i23, i68, i20, i65 for some reason
[00:45:00] <PCW> probably best just dropped

[00:48:13] <seb_kuzminsky> thanks
[00:48:23] <jepler> I don't suppose the others => syntax can be used in ModuleID or PinDesc
[00:48:34] <PCW> the Spartan 6 builds require some funny options so may want to look at my batch file of xilinx cmd_log
[00:48:47] <PCW> maybe

[00:49:50] <seb_kuzminsky> i see no need for a merge commit
[00:50:34] <seb_kuzminsky> aight, imma ingest that and extrude 2.6.3

[00:50:47] <seb_kuzminsky> thank *you*
[00:51:26] <jepler> PCW: no new card support in hostmot2-firmware yet, that's an obvious next step though
[00:51:46] <jepler> quite a few new cards and their firmwares to add, too
[00:52:04] <PCW> yes lots of SP6 cards
[00:52:13] <jepler> looks like 3x20 was the latest card added, not that I know the chronology offhand
[00:52:38] <jepler> to me, this matters more for the cards with only volatile firmware

[05:01:30] <seb_kuzminsky> so, yay, it complained about a problem, for once, instead of accidentally peeing on itself

[14:25:41] humble_s1a_bass is now known as humble_sea_bass
[14:27:13] <meji3> i guess i could try it out then
[14:27:39] <meji3> building a new cnc and having bought a few things i had to resell/return
[14:27:45] <meji3> i'm trying to be a bit more careful
[14:28:03] <meji3> what would be an equivalent board that might lead to less issues
[14:28:22] <meji3> i guess i should say first cnc

[15:04:31] <pcw_home> I have never had an issue with ROM/RAM initilization (and I use 13.1 all the time)
[15:04:33] <pcw_home> I think the warning is for actual 9K RAMs (with parity) but I dont use them
[15:05:05] <jepler> OK
[15:05:22] <jepler> this morning I've got 7i90 epp, 7i90 spi, and 7i80 bitfiles, but none of them tested yet.
[15:07:19] <pcw_home> 7I80 bitfiles should be easy enough to test
[15:07:40] <jepler> yes, that's going to be the easiest
[15:07:54] <jepler> I've also refactored how configurations are specified
[15:08:00] <pcw_home> just done bust both flash images
[15:08:07] <jepler> instead of a growing number of lookup tables, each one will be a class

[15:14:29] <pcw_home> but thats a long ways off, need to get IDROMV4 working first
[15:16:17] <jepler> always more to do
[15:16:56] <pcw_home> I should have started off with V4
[15:19:17] <jepler> when you run out of things to do, you should stick in a ring oscillator trng module into hostmot2
[15:20:30] <jepler> I misplaced the code for the one I wrote years ago
[15:21:23] <pcw_home> multiple ring oscillators for random number generation?
[15:22:23] <jepler> At its base, Intel's original HWRNG involved a free-running ring oscillator that was sampled by a synchronous process that whitened it
[15:22:54] <pcw_home> must have to use the "keep" attribute or similar so they don't get optimized away
[15:24:04] <jepler> yes something like that
[15:24:27] <pcw_home> Ive heard a good way to fry a FPGA is make each LUT a ring oscillator
[15:24:46] <jepler> I think my 5i20's FPGA felt warm when I did this
[15:25:18] <jepler> > The Intel 82802 Firmware Hub (FWH) chip included a hardware RNG[9] using two free running oscillators, one fast and one slow. A thermal noise source (non-commonmode noise from two diodes) is used to modulate the frequency of the slow oscillator, which then triggers a measurement of the fast oscillator. That output is then debiased using a von Neumann type decorrelation step (see below). The output rate of this device is some
[15:25:27] <jepler> this is the scheme I was thinking of, I see I oversimplified it
[15:26:17] <jepler> others have done FPGA random numbers; they went to the trouble of characterizing the rate variation of FPGA ring oscillators in order to bolster their argument that there was sufficient entropy there due to thermal variation
[15:27:10] <pcw_home> I would worry about phase locking

[18:13:10] <pcw_home> Great!
[18:13:11] <pcw_home> reload is really nice, I was wearing my fingers out pulling the 7I76E power connector :-)
[18:14:05] <micges-dev> heh me too
[18:14:32] <micges-dev> also great time saver with 5i25 testing
[18:15:23] <pcw_home> yeah (5i24 6i24 6i25 also)

[18:16:33] <pcw_home> 7i90 has ICAP added to the source but I have not rebuilt the bitfiles yet
[18:19:18] <micges-dev> so I can add ICAP cookie checking to all supported boards?
[18:19:30] <pcw_home> yes
[18:24:11] -!- gleapsite has quit [Read error: Connection reset by peer]
[18:25:02] <pcw_home> well except hm2_eth and hm2_serial
[18:25:51] <micges-dev> yeah
[18:28:55] <pcw_home> and hm2_serial doent have the hm2_eth assy code merged yet
[18:30:37] <micges-dev> what assy code?
[18:31:40] <pcw_home> hm2_serial uses basically the same ROM code as 7I80
[18:32:14] <pcw_home> (with a pktuart instead of a Ethernet MAC)
[18:32:26] <micges-dev> ah
[18:32:59] <pcw_home> this is sufficient to test the DPLL stepgen sampling:
[18:33:01] <pcw_home> setp hm2_[HOSTMOT2](BOARD).0.raw.write_address 0x2A00
[18:33:02] <pcw_home> setp hm2_[HOSTMOT2](BOARD).0.raw.write_data 0x00009000

[18:33:58] <micges-dev> oh thanks
[18:35:03] <micges-dev> 7i92 support added to mf, test when you can
[18:37:39] <jepler> boo, wrote a size-25 bitfile to my size-16 7i80. recovered from that now.

[19:04:24] <jepler> pcw_home: it looks like the manual says to use reset_on_error:enable but that the actual flag is probably reset_on_err
[19:04:52] <jepler> and the value is :Yes, not :enable
[19:09:33] <pcw_home> Is this the reset on crc error stuff?
[19:09:47] <jepler> in the manual under section "bitfile format"
[19:10:55] <jepler> for hostmot2-firmware I guess I should figure out how to use your "but.src" (*cough*) files
[19:11:32] -!- f1oat has quit [Ping timeout: 255 seconds]
[19:11:56] <pcw_home> I know the current settings work. One problem with the SP 6 configs is that the fallback option is a global variable

[19:11:59] -!- Komzzzpa has quit [Ping timeout: 252 seconds]
[19:12:27] <pcw_home> it probably should be in the pinout file
[19:12:30] -!- rythmnbls has quit [Quit: Leaving]
[19:14:05] <jepler> pcw_home: you mean the behavior where the INIT LED blinks is actually something in the bitfile?
[19:14:15] <pcw_home> yes
[19:14:22] <jepler> and not even that, it's not set by a bitgen -g flag either?
[19:14:43] -!- gleapsite has quit [Read error: Connection reset by peer]
[19:14:51] <jepler> for linuxcnc should I bother building a "fallback" configuration?

[19:44:05] <skunkworks_> since when did feed hold stop working for rapids?
[19:44:10] -!- gleapsite has quit [Read error: Connection reset by peer]
[19:44:16] <skunkworks_> (slight suprise...)
[19:44:38] <skunkworks_> I know it is 'feed' hold but I am almost positive it worked for rapids also
[19:44:57] <skunkworks_> (2.6.0)
[19:45:12] <skunkworks_> I could just not be remembering right
[19:46:57] amnesic is now known as amnesic_away
[19:47:39] <micges-dev> jepler: mf won't be able to write incorrect bitfile to flash anymore
[19:47:49] <pcw_home> I think all the bitgen options are the same for SP6 cards
[19:48:09] <pcw_home> bbl again
[19:49:38] <micges-dev> skunkworks_: I *think* it could be side effect of spliting feed override and rapid override as feed hold is just setting feedoverride to 0.0
[19:49:45] -!- gleapsite has quit [Read error: Connection reset by peer]
[19:50:01] <micges-dev> and now FO doesn't affect rapids at all
[19:50:11] <skunkworks_> micges-dev: that was my thought
[19:50:16] <skunkworks_> the question is - what is right?
[19:51:07] <micges-dev> I vote for feedhold stop rapid also despite the pin name
[19:52:05] <skunkworks_> that might work - then you could hook them together if you want
[19:54:23] <micges-dev> I was thinking about old behavior but your idea is better
[19:55:06] <skunkworks_> heh - we communicate like we are married...
[19:55:07] <micges-dev> same was for FO and RO, if you want old behavior just net them together
[19:55:15] <skunkworks_> right
[19:56:43] <micges-dev> skunkworks_: oh so it seems that marriage communcation problems are the same around the globe ;)

[22:00:38] <jepler> then hopefully I can use my assembler to start building those d8* ROMs
[22:00:45] <jepler> and then my software building fetish will be satisfied
[22:01:48] <pcw_home> will your assembler work on the D16?
[22:02:50] <jepler> hopefully
[22:02:58] <jepler> I think we discussed that it has a 24-bit instruction word
[22:03:06] <jepler> that's not a problem
[22:03:23] <pcw_home> Yeah (the B32 has a 24 bit instruction also)
[22:04:07] <jepler> but obviously at this point there's only one table for it so surprises may lurk
[22:04:17] <jepler> not to mention needing variant tables for all these versions of the d8 you've done over the years
[22:05:16] <pcw_home> Not needed (I moved everything but USB to the latest)
[22:05:16] <jepler> are there relative jumps? the lack of those in d8 means I haven't thought about them yet.
[22:05:16] <jepler> cool, I know you had talked about doing that
[22:05:17] <pcw_home> no relative jumps
[22:05:46] <pcw_home> i even have example code for the twiddler (untested)
[22:05:49] <jepler> I don't think they represent a problem, instructions know what address they're assembling to, and the address of the arguments
[22:06:23] <pcw_home> never had the goal of PIC
[22:06:40] <jepler> I should do 6502 or something else that I can read and write by hand
[22:07:14] <pcw_home> I can just about read and write D8 code (in hex)
[22:07:57] <pcw_home> I pretty much had the TMS9900 inst set memorized at one time
[22:08:16] <jepler> I probably had about 1/4 of the d8 opcodes memorized while I was staring at differences between hex files
[22:08:35] <jepler> "that's a load from memory and it's different by one byte .. wtf"
[22:08:52] <pcw_home> pretty simple (PDP8 is fancier)
[22:10:50] <jepler> I know I'm showing my youth, but 6502, x86, and MIPS are the three oldest assembly languages I've dipped my toes in (and mips only for school, of course)
[22:11:54] <pcw_home> I toggled a sieve or Eratosthenes program into a PDP8S :-(
[22:13:06] <pcw_home> (it showed the primes on the console lights)
[22:13:37] <jepler> I entered tons of hex listings as a kid, but by then they had fancy check digit calculators so you knew when you were wrong and got to correct your mistakes
[22:14:21] <jepler> hm, any div instruction on pdp8s?
[22:14:43] <pcw_home> only if you had the hardware option

[22:17:25] <micges-dev> jeez guys, I couldn't switch on a computer in 2001...
[22:17:53] <pcw_home> :-)
[22:20:22] <pcw_home> looks like you can set the P term quite high in the stepgen control loop once you get rid of the sampling noise
[22:23:17] <pcw_home> Using 1000 now and getting <50 uinch deviations during
[22:23:18] <pcw_home> accel/decel (20 IPS 400 IPS*S) less than 4 uinch during 20 ips cruise
[22:24:28] <pcw_home> unfortunately getting this performance does require tuning FF2 to minimized errors during accel/deccel
[22:26:53] <micges-dev> very good numbers
[22:28:04] -!- mhaberler has quit [Quit: mhaberler]
[22:28:26] <pcw_home> considering the noise was about +-2 mills before :-)
[22:29:38] <jepler> how many steps/inch? or is this error scale independent of step size?
[22:30:00] <pcw_home> i dont think so
[22:31:00] <pcw_home> scale is set to 10000 steps/inch
[22:31:28] <jepler> so 100 uinch = 1 step, or your error is a half step worst case?
[22:31:38] <pcw_home> yes

[22:33:12] <pcw_home> I need to add some P and remove some I from my DPLL if has mild overshoot (~1 second period)
[22:33:33] <pcw_home> makes me seasick watching it
[22:34:02] <jepler> at some point you'll need to add a 1pps input from a gps so that we can know our velocities are accurate

[23:00:33] <jepler> don't install the package 'adjtimex'. It *sounds* like a program for reading the kernel adjtimex parameters, but it appears to try (at installation time without confirmation) to discipline linux's timekeeping to follow the RTC but either my RTC is crazy bad or adjtimex (the program) is crazy bad
[23:00:47] <jepler> it made my clock go about 1% slow
