| 00:01.01 | cr2 | ok. i don't need = before the label. then it looks much better. |
| 00:01.35 | cr2 | so i did: |
| 00:01.45 | cr2 | ldr r7. myfb |
| 00:01.47 | cr2 | ... |
| 00:02.09 | cr2 | myfb: .long 0xa3faa000 |
| 00:04.18 | awelux_ | hihi |
| 00:04.29 | awelux_ | I get into the preloader ! |
| 00:04.43 | cr2 | great! |
| 00:04.44 | awelux_ | that took how many days ? |
| 00:04.46 | awelux_ | 10? |
| 00:04.51 | cr2 | :) |
| 00:08.15 | cr2 | assembler programming is fun. |
| 00:08.53 | cr2 | now i need to understand why sti() and icmr=0 break my fb refresh. |
| 00:12.03 | awelux_ | And I need to check if I get past the MMU switch off |
| 00:12.24 | cr2 | it should be easy ? |
| 00:12.44 | awelux_ | yes. easy |
| 00:12.49 | awelux_ | njust takes time |
| 00:12.52 | awelux_ | ... |
| 00:12.56 | awelux_ | and a cold reset |
| 00:13.13 | awelux_ | I guess that is a good sign |
| 00:13.25 | cr2 | + for wince2005. |
| 00:14.00 | awelux_ | wince2005 needs no cold reset? |
| 00:14.42 | cr2 | no. |
| 00:16.53 | awelux_ | :/ |
| 00:17.04 | awelux_ | the mmu switch off fails it seams |
| 00:17.42 | cr2 | that is difficult. it is probably the most hardcore arm stuff. |
| 00:18.59 | awelux_ | I will continue tomorrow. cu cr2 |
| 00:19.06 | cr2 | good night. |
| 00:19.21 | awelux_ | all these cold resets are taking to long for tonight ^^ |

| 19:38.56 | awelux__ | what is the scope of this library? All gsm realted stuff or just managing connections? |
| 19:47.37 | cr2 | hi awelux |
| 20:01.37 | cr2 | found one more dumb mistake. if the interrupts are disabled you can't call sleep() ;) |
| 20:05.56 | awelux__ | eh. yes. I noticed that a while ago ;) |
| 20:06.51 | cr2 | writing to the fb works well. now i need to check if the mov pc, r3 is passed. |
| 20:09.38 | awelux__ | I found that I get past the MMU code |
| 20:09.49 | awelux__ | but not the lines before that invalidate the cache |
| 20:11.00 | awelux__ | And I downloaded the xscale manuals |
| 20:11.01 | cr2 | the tlb ? |
| 20:11.37 | awelux__ | the xscale core developers manual |
| 20:12.07 | awelux__ | on the intel ftp in downloads/xscale is some interesting stuff |
| 20:13.32 | awelux__ | I'm still searching the xscale architecture reference manual though |
| 20:13.44 | cr2 | ok. i will think about writing to the asic3 gpio reg. |
| 20:13.53 | awelux__ | oh |
| 20:14.01 | awelux__ | Ah good ;) |
| 20:14.14 | awelux__ | I mean the arm architecture reference manual |
| 20:14.42 | cr2 | it's probably on the arm site. |
| 20:44.41 | cr2 | ok. i can boot the kernel with the IR console now. the kernel oopses, but it is probably a config problem. the ir output is messed up, and the pxafb is not initialized. hmm. |
| 20:45.04 | awelux__ | still nice |
| 20:45.27 | cr2 | have you found the ir enable gpio ? |
| 20:45.58 | awelux__ | I don't have an ir port on my pc anyway |
| 20:46.16 | awelux__ | I've a small ir adapter for the serial port though |
| 20:46.37 | awelux__ | It was for using remote controls. |
| 20:46.44 | awelux__ | I can use it with irda |
| 20:46.56 | awelux__ | not sure if that would work as console |
| 20:47.18 | awelux__ | But for now that is not important |
| 20:47.25 | awelux__ | I still don't reach the kerneƶ |
| 20:47.33 | cr2 | ok. i think that booting is not a problem now. pxafb is a problem. |
| 20:47.41 | cr2 | try my version. |
| 20:49.35 | awelux__ | upload. |
| 20:49.54 | awelux__ | the source |
| 20:49.59 | cr2 | i have commented out the non-portable stuff. |
| 20:50.04 | awelux__ | ok |
| 20:50.08 | awelux__ | good |
| 20:52.29 | cr2 | ok. uploaded. |
| 20:53.08 | cr2 | run a diff to be sure. |

| 20:58.22 | awelux__ | the ARM reference manual |
| 20:58.24 | awelux__ | 800 pages |
| 21:48.42 | cr2 | awelux, i have usb eth gadget running, ping -f works :) can't login, probably the dropbear in the ramdisk is confused. ir output is not really readable. |

| 22:21.53 | cr2 | i can login over usb-rndis |
| 22:21.59 | cr2 | and mount the sd card |
| 22:22.29 | cr2 | and write to the sd card, so the asic3 sd driver works. |

| 23:01.32 | awelux__ | <-- was playing bzflag again |
| 23:01.56 | cr2 | :) |
| 23:02.21 | cr2 | i think you will have the same problems (and solutions) now. |
| 23:03.01 | awelux__ | didok. |
| 23:03.22 | awelux__ | mcrp15, 0, r0, c7, c10, 4@ Drain write buffer |
| 23:03.22 | awelux__ | mcrp15, 0, r0, c7, c7, 0@ invalidate I+D & BTB |
| 23:03.29 | awelux__ | these still seam to cause problems |
| 23:03.38 | cr2 | hmm. |
| 23:04.04 | cr2 | i have thought that you can boot my kernel on magician. |
| 23:04.15 | awelux__ | I didn't try that yet. |
| 23:04.19 | awelux__ | Will do |
| 23:04.21 | cr2 | pxafb params are different, but is does not work anyway. |
| 23:04.36 | cr2 | you can also comment out the asic3 stuff. |
| 23:04.47 | cr2 | usb is the same and should work. |
| 23:05.03 | cr2 | my ramdisk is from blueangel. |
| 23:05.14 | awelux__ | do I have to select a certain port? |
| 23:05.32 | cr2 | with the "universal" modules added |
| 23:05.33 | awelux__ | my magician is using 192.168.131.201 right now |
| 23:05.40 | cr2 | -un0 branch. |
| 23:06.08 | cr2 | 192.168.0.205 - host , 206 - phone. exactly as the blueangel. |
| 23:06.25 | awelux__ | What is the IoRemap doing ? |
| 23:06.44 | cr2 | you don't need it. |
| 23:06.49 | awelux__ | I should try to reconfigure my firewall for these ports then |
| 23:06.58 | cr2 | it is a dirty hack. |
| 23:08.29 | cr2 | compile the pxa-mci modules. |
| 23:09.06 | cr2 | with the correct irq you should have a working mmc (maybe sd too). |
| 23:09.23 | awelux__ | wow |
| 23:09.38 | awelux__ | sounds quite good. what haret to use? your new one ? |
| 23:09.51 | cr2 | yes. |

| 23:10.40 | cr2 | it works very stable now. |
| 23:12.05 | cr2 | maybe needs a patch to work with bigger ramdisks. but not really necessary to help bloatware writers ;) |
| 23:14.41 | awelux__ | bloatware. Image: |
| 23:15.15 | awelux__ | currently when writing software you don't reinvent everything but take other modules when they exist |
| 23:15.38 | awelux__ | now these modules usually have dependencys on their own. |
| 23:16.31 | awelux__ | nif the each module needs more than one other module on average to run the amount of modules needed goes against infinity. |
| 23:16.54 | cr2 | i have 900K kernel + 5.3MB ramdisk. the tests say it will work up to 7.5MB |
| 23:16.56 | awelux__ | that's why you can easily install 1-2 CD's of software just to get a webpage running |
| 23:17.09 | cr2 | there is an X server on the ramdisk!!! |
| 23:17.16 | awelux__ | wow |
| 23:17.19 | cr2 | +850K |
| 23:18.28 | cr2 | but you can't remove it with just "rm" :) |
| 23:22.43 | awelux__ | wow |
| 23:22.53 | awelux__ | the blue line on the sceen just got red |
| 23:23.01 | cr2 | yes. |
| 23:23.17 | cr2 | wait a bit. |
| 23:23.33 | awelux__ | I added an led off command. |
| 23:23.54 | cr2 | then connect the usb cable and do "lsusb" |
| 23:24.55 | awelux__ | that no change there |
| 23:25.21 | awelux__ | what I don't understand: |
| 23:25.34 | awelux__ | The part that draws red pixels in the asm is commented out |
| 23:26.32 | cr2 | there is c code before linux_start |
| 23:26.54 | awelux__ | ah. good |
| 23:27.30 | awelux__ | I understand |
| 23:28.46 | awelux__ | you used that instead of switching of led's or so |
| 23:28.54 | awelux__ | to see where you can gt |
| 23:28.57 | awelux__ | *get |
| 23:29.37 | cr2 | black,blue,green,red. should be a function. |
| 23:30.13 | awelux__ | what was the problem with the old code ? |
| 23:30.36 | awelux__ | you changed the way how memory for the kernel is allocated |
| 23:31.11 | cr2 | the ptable entries were sometimes =0xffffffff. it is never tested. |
| 23:32.43 | cr2 | allocating memory with malloc() is not very wince-physmem-alloc-style. malloc is LocalAlloc. stupid micro$oft invention. |
| 23:33.11 | cr2 | what a braindamage. |
| 23:34.18 | awelux__ | if writing braindamadged stuff helps them that no sane person would want to emulate their API they reached theri goal ;) |
| 23:36.14 | cr2 | instead of the linux ioremap they have such an obfuscated code api with obscure parameters, that their own programmerz made multiple mistakes in the inplementation! |
| 23:38.04 | cr2 | mmiospace was leaking memory, and it is _necessary_ to use virtualfree(,mem_decommit) before virtualfree(,mem_release). the m$ docs don't say that. it is "empirical knowledge". |
| 23:38.36 | awelux__ | lol |
| 23:40.24 | *** join/#htc-blueangel dullard (n=jim@adsl-static-1-30.uklinux.net) |
| 23:41.21 | cr2 | it is actually virtualfree(ptr,size,*) but the "size" _must_ be zero on "physical" allocations, otherwise you will leak memory :) and it was ms own code that leaked memory ! |
| 23:42.03 | cr2 | high quality programming. |
| 23:42.24 | cr2 | linux is so simple compared to that shit. |
| 23:43.33 | awelux__ | yes. But you have to give them credit that it's convenient for the end user. Not sophisticated or great but convenient, |
| 23:45.57 | cr2 | if somebody has ported the coredll from wine to wince and has written the coff loader, wince will be really toast. and wince-wine will be much easier than "real" wine. |
| 23:46.51 | cr2 | ms made it really easy. if you will look at the coredll disassembly, it is a jump table. |
| 23:48.07 | awelux__ | hmm. good plan ^^ |
| 23:48.45 | awelux__ | nyes. if users could ru their wince apps on any handheld they wouldn't care if it's running wince or linux |
| 23:50.02 | awelux__ | gee. how can you live with a new gnuharet name on every recompile ? |
| 23:50.29 | cr2 | i remember running solitair in 1995 on my 386dx25 linux box with 4MB ram. that was really cool. would like to test that on wince :) |
| 23:50.51 | cr2 | it was intentional. to upload the binaries to sf.net |
| 23:51.07 | awelux__ | ic. |
| 23:52.11 | cr2 | make inst and make instz |
| 23:52.26 | awelux__ | 1995 is early. I converted from win to linux from 1997-1998 |
| 23:53.07 | awelux__ | I remember I installed several win95 betas but had no interest in updating to win98 |
| 23:53.32 | cr2 | i converted in late summer 1994 :) that's why i am so much anti-ms zealot :) |
| 23:53.33 | awelux__ | Actually I deleted the win98 just last year. |
| 23:53.39 | cr2 | :) |
| 23:53.44 | awelux__ | 1994 is freaking early |
| 23:54.43 | cr2 | i worked with x11 on a vax before even seeing windows 3.0. win3.1 was very lame. no network display, no tcpip. |
| 23:54.53 | cr2 | :) |
| 23:56.27 | cr2 | and idiotic turbo pascal and m$ fortran with 64K segments for code and data. when there as 16MB ram on the vax, and good DEC compilers that really used it. |
| 23:57.01 | awelux__ | ah. yes compared to such compuers the early pc's must have been real toys. |
| 23:57.43 | awelux__ | I've an old slackware CD here with kernel 1.2.13 |
| 23:58.09 | awelux__ | I rmember we installed it once and started X |
| 23:58.21 | awelux__ | But we were not impressed. We didn't start a WM ;) |
| 23:59.34 | cr2 | then there was alpha with 64bit cpu already in 1993. DEC was so great in engineering... |
