| 01:19.33 | ds2 | solar: oh |
| 01:20.02 | ds2 | solar: is this going to be a EABI setupp? |
| 01:21.38 | solar | ds2: yes from day 1 it's been armv4tl-softfloat-linux-gnueabi built with -Os -pipe -march=armv4t -mtune=arm9tdmi -fomit-frame-pointer |
| 01:22.22 | ds2 | solar: do you know if the executables built that way will run on a later ARM? |
| 01:23.15 | solar | you mean like could it be ziped up and used on a device like an omap1 chip? |
| 01:23.30 | solar | should be. arm9tdmi would be a subset of arm10tdmi right? |
| 01:23.36 | ds2 | or say a ARM11 Cortex device |
| 01:23.53 | solar | ahh. thats the next thing I'm working on. |
| 01:23.56 | ds2 | I have heard there are some oddities to a ARMv4t setup vs the later ARMv5, etc |
| 01:23.57 | solar | for the beagle stuff? |
| 01:24.05 | ds2 | beagle or anything that is not ARMv4t |
| 01:24.18 | ds2 | that has been the problem with getting EABI onto ARMv4t |
| 01:26.01 | solar | I think we have a user with the beagle who has been using. armv6j-softfloat-linux-gnueabi (-march=armv6j -mfloat-abi=softfp -mfpu=vfp -meabi=4) etc.. |
| 01:26.37 | ds2 | why armv6j? |
| 01:27.32 | solar | the problem with armv4t is that gcc itself defaults to arm10tdmi for all EABI's afaik. Long standing bug. |
| 01:27.49 | solar | sed -i -e s/'define SUBTARGET_CPU_DEFAULT TARGET_CPU_arm10tdmi'/'define SUBTARGET_CPU_DEFAULT TARGET_CPU_arm9tdmi'/g gcc/config/arm/linux-eabi.h ; # fixes it |
| 01:28.01 | ds2 | Hmmm |
| 01:28.24 | ds2 | but shouldn't the beagle (cortex-a8) use armv7j or equiv? |
| 01:28.45 | solar | I don't think it works like in the tuple for whatever reason. |
| 01:28.48 | solar | searches |
| 01:29.44 | ds2 | Hmm, you are using stock GNU gcc I take it? |
| 01:30.05 | solar | -march=armv7-a -mtune=cortex-a8 (looks like what others are using) |
| 01:32.36 | ds2 | btw, you got a working rootfs for armv7? |
| 01:32.56 | ds2 | too lazy to build one and don't want to use Angstrom ;) |
| 01:33.54 | solar | ds2: stock gentoo cross toolchains. currently for the 8050. it's binutils-2.18-r3 gcc-4.2.4 glibc-2.7-r2 |
| 01:36.29 | solar | I don't have a rootfs for that yet sorry. I'm only working on armv4tl- and armv5te(omap1) now. When I get done with the armv4 stuff I'd like to jump over to rootfs/firmwares for armv7a stuff |
| 01:38.16 | ds2 | 'k I can help with that if needed |
| 01:38.27 | ds2 | just much rather be in kernel land then userland |
| 01:44.43 | solar | ds2: all depends on what you are looking for in a UL. Looking for a simple firmware image? PDA style? ARM Fullish Desktop and Dev env? |
| 01:45.15 | solar | the beagle in my eyes is begging to be put in some cheap plastic and called a laptop |
| 01:45.48 | solar | or a tablet |
| 01:47.38 | ds2 | solar: I just need something to give me a shell to test stuff.. I am using the MV userland at the moment and it works, just nice to have a newer one |
| 01:48.08 | ds2 | indeed... once the holidays are over, I think I'll have time to machine up a nice case for it |
| 01:55.16 | solar | steam punk it, and sell em :) |
| 01:59.39 | ds2 | heh... not the way I am making it |
| 02:00.02 | ds2 | CNC machined cases will probally have to sell for $200-$300 each to make it really worth doing :( |
| 02:00.11 | ds2 | and the volume don't justify molding them |
| 02:00.57 | ds2 | had a snazzy solid ABS design in mind, but not many local sources of ABS sheets |
| 02:11.41 | MonMotha | solar: the beagleboard sadly is riddled with errata and doesn't bring much out in terms of I/O |
| 02:11.57 | MonMotha | they clearly wanted to get by with a lesser spec PCB than that package would normally dictate |
| 02:13.34 | solar | MonMotha: non exposed i/o pins etc.. ? |
| 02:16.25 | solar | ds2: any size desires/limits for that UL? Need RO or RW runtime is fine? Would a tarball be ok? |
| 02:47.18 | ds2 | solar: fits in a 512-128M of space wouldbe nice; RW, target is good... it'll go on an SD card |

| 23:50.10 | ds2 | solar: some guy actually did it for the N800 so it does cross compile |
| 23:50.16 | solar | Will be focusing on enlightenment soonish also. |
| 23:50.18 | ds2 | I suppose I can steal his binaries ;) |
| 23:51.03 | solar | -Os -pipe -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp (seems to be right) |
| 23:51.22 | solar | I hope the -mfpu= is right for both cortex devices. |
| 23:51.36 | ds2 | both?? |
| 23:51.52 | ds2 | AFAIK, they is only one |
| 23:52.20 | solar | ds2: beagle board and the pandoa device. (same fpu in both?) |

| 23:52.35 | ds2 | but I think neon is right; avoids a vfp bug... but there might be gcc bugs lurking, the CSL folks have been having a hard time releasing a bug free compiler |
| 23:52.46 | ds2 | solar: both uses the same Cortex-A8 core |
| 23:52.55 | *** part/#edev mjtrangoni (n=mt@host10.190-31-111.telecom.net.ar) |
| 23:54.21 | solar | ds2: well last night you were aiming for simply a busybox+uclibc setup. Can I slap a mini-image together so you can confirm if the bins even work? |
| 23:55.02 | ds2 | solar: I just found out about a potential demo thing this morning... but sure |
| 23:55.10 | ds2 | send me the bins and I can test them right now |
