  • [16:07:55] <mru> you can always choose to not use haskell at all
  • [16:08:03] <bgamari> apparently they wanted the ability to link static objects at runtime
  • [16:08:24] <mru> functional programming is mainly of academic interest anyway
  • [16:08:29] <bgamari> I disagree
  • [16:08:33] <mru> of course you do

  • [16:10:05] <bgamari> no no, I understand. You are in large part right. It certainly doesn't have the user base that many imperative languages have. There's probably a reason for that

  • [16:11:10] <mru> monte carlo what?

  • [16:11:46] <mru> try something a few million lines of code in size
  • [16:11:47] <bgamari> It was a monte carlo simulation of photophysical effects in a single molecule fluorescence system
  • [16:11:59] <bgamari> mru: Fair enough, perhaps you are right
  • [16:12:14] <bgamari> but for my tasks I've found it very well suited and a lot of fun to work in
  • [16:12:18] <mru> functioonal programming languages are still interesting
  • [16:12:31] <mru> they enable other ways of reasoning about problems
  • [16:12:51] <bgamari> yep, hence my interest in GHC
  • [16:12:53] <mru> and can give insights eventually resulting in better procedural compilers

  • [16:39:03] <bgamari> yep
  • [16:39:20] <mru> but you missed the veneer by 8 bytes
  • [16:39:26] <bgamari> looks like it

  • [16:49:00] <bgamari> I seem to compute the correct offset
  • [16:49:36] <bgamari> the relocation was at P=0x41c61d50, the offset was 009809a0
  • [16:49:53] <bgamari> P+offset = 0x425E26F0, so I guess it must be the instruction encoding
  • [16:54:37] <bgamari> mru: my instruction encoding is quite simple
  • [16:54:47] <bgamari> if word points to the instruction
  • [16:55:18] <bgamari> *word = (*word & 0xff000000) | ((offset>>2) & 0xffffff)
  • [16:55:30] <bgamari> is there something wrong with this
  • [16:55:52] <bgamari> Considering the instruction is a BL, there should be no H bit to take care of

  • [16:58:36] <mru> remember that the offset is relative the visible pc value
  • [16:58:44] <mru> which is 8 more than the address of the instruction
  • [16:58:52] * mru thinks you probably forgot that
  • [17:00:08] <bgamari> oh man
  • [17:00:20] <bgamari> Why is this the case?
  • [17:00:27] <mru> historical reasons
  • [17:00:42] <bgamari> blarg
  • [17:00:43] <mru> in thumb code the offset is 4 btw
  • [17:00:49] <mru> great fun
  • [17:01:19] <bgamari> oh yes
  • [17:01:21] <mru> the reason is that it simplified the design of some processor a very long time ago
  • [17:02:14] <bgamari> So P in the ELF for ARM spec refers to Address - 8 for ARM code, Address - 4 for Thumb code?
  • [17:03:20] <mru> "P is the address of the place being relocated"
  • [17:04:17] <bgamari> Alright, so I shouldn't need to account for this in the relocation code?
  • [17:04:18] <mru> read section 4.6.1.1
  • [17:04:27] <mru> "Addends and PC-bias compensation"
  • [17:04:36] <bgamari> Just where I need to jump to veneer?
  • [17:05:16] <bgamari> I have, just checking
  • [17:05:23] <mru> P is the address of the branch instruction
  • [17:06:15] <nikarul> Hey, does anyone here use a KVM with their Beagleboard? Just curious if I can safely switch ports without damaging my board.
  • [17:06:28] <bgamari> I'm just wondering if I need to account for this 8/4 byte offset anywhere but the veneer branches
  • [17:06:38] <mru> you need to account for it somewhere
  • [17:06:49] <mru> veneer branches are no different
  • [17:06:53] <mranostay> nikarul: how would that damage it?
  • [17:07:26] <nikarul> Well the manual says not to plug in the DVI port when the board is on. Not sure KVM switching would be the same as plugging it in.
  • [17:07:48] <bgamari> mru: The addend doesn't already account for the offset?
  • [17:07:49] <nikarul> probably not but expensive to test if I'm wrong.
  • [17:08:51] <mru> bgamari: read the spec
  • [17:09:24] <mru> it should already be compensated for in the relocation
  • [17:09:28] <mru> what produced it?
  • [17:11:10] <bgamari> The assembler?

  • [17:19:02] <mru> you probably simply forgot to take the pc bias into account when computing the branch offset to the veneer
  • [17:21:30] <bgamari> yes, that appears to be the issue
  • [17:21:36] <bgamari> now I get GHC specific problems
  • [17:21:42] <bgamari> but the linker seems to be working

  • [19:06:57] <Tobba> I asked yesterday about this, but I dont think anyone actually had any clue
  • [19:07:32] <Tobba> Theres a pretty much 99% chance every boot that the BeagleBoard just throws back to the bootloader in its booting process
  • [19:07:38] <Tobba> On any linux distro ive tried
  • [19:07:41] <Tobba> Same place too
  • [19:07:52] <Tobba> But after about 100 reboots it decides to work
  • [19:08:38] <prpplague> Tobba: there could be a number of reasons for the failure
  • [19:09:18] <prpplague> Tobba: it would be hard to give you an exact reason without spending a large amount of time to help you debug it
  • [19:10:51] <Tobba> http://pastebin.com/ACycP9sb
  • [19:11:00] <Tobba> Any idea what it does right after those USB messages though?
  • [19:11:15] <Tobba> When it decides to boot it gets to the failure step 100 times slower
  • [19:11:56] <prpplague> Tobba: could be a dozen things
  • [19:12:33] <Tobba> Darn it
  • [19:12:41] <Tobba> Its probably physical damage though
  • [19:12:48] <Tobba> Since it refuses to boot ANY linux
  • [19:13:22] <Tobba> Guess i'll have to get a new from my local supplier
  • [19:13:28] <Tobba> But I was hoping to get some work done over the weekend

  • [19:18:16] <Tobba> Interesting that it randomly broke though
  • [19:18:29] <Tobba> But yeah, i'll get an RMA, but its weekend
  • [19:18:37] <Tobba> Time to spend an hour trying to fire it up
  • [19:18:59] <djlewis_> Tobba: you local supplier have them in stock?
  • [19:19:06] <djlewis_> get him to swap it out
