Guest BlackTigerX Posted July 17, 2011 Report Share Posted July 17, 2011 (edited) rebel1, Unpacked your boot.img and replaced the ramdisk with the 'stock' vegacomb one. Added to 1.7 vegacomb and flash the tablet. Got corrupt screen green and red lines then grey screen. Now I need to get the windows pc running again so I can nvflash it again. Unless you have any great tips on how to do this via Linux. I will have a look at the ROM you have uploaded and I'll try to strip in down ("a lot") for you. Billy.. Billy, could you upload rebel1's kernel with the replaced ramdisk please? Would like to test some things here :) Edited July 17, 2011 by BlackTigerX Link to comment Share on other sites More sharing options...
Guest wooshy1 Posted July 17, 2011 Report Share Posted July 17, 2011 (edited) first off great work on this kernel eduardo rebel1, Unpacked your boot.img and replaced the ramdisk with the 'stock' vegacomb one. Added to 1.7 vegacomb and flash the tablet. Got corrupt screen green and red lines then grey screen. Now I need to get the windows pc running again so I can nvflash it again. Unless you have any great tips on how to do this via Linux. I will have a look at the ROM you have uploaded and I'll try to strip in down ("a lot") for you. Billy.. Yeah I got this far it is probably something todo with the nand map and/or the memory map in the vegacomb kernel be different to that in the eduardo kernel. I was going to try fastbooting eduardo kernel + vegacomb ramdisk + vegacomb kernel command line parameters but i have run out of time tonight :( eduardo did mention earlier in this thread that he wasnt sure if the nand partitions could be set from the command line if they cant the kernel needs to be rebuilt with the vegacomb nand partition sizes and/or memory map. btw nvflash is available for linux. Think its part of the linux 4 tegra pack a few posts back. also the iconia system image is for a 2.6.36 kernel, i dont know what changes, if any, have been made to the vegacomb system to get it to run on the 2.6.32 kernel Edited July 17, 2011 by wooshy1 Link to comment Share on other sites More sharing options...
Guest BillyBobJoe Posted July 17, 2011 Report Share Posted July 17, 2011 first off great work on this kernel eduardo Yeah I got this far it is probably something todo with the nand map and/or the memory map in the vegacomb kernel be different to that in the eduardo kernel.

Thanks wooshy1, I too have run out of time for tonight. eduardo did mentions that the memory map was set in the build and wasn't sure if they could be over ridden at the command line, but it would be good if some gave it a go. I was looking at trying this kernel on a Transformer ROM to see where I gets to. My kids enjoy the working title of my work-in-progress - NitComb (as it's full of bugs).....maybe a new Comb for the Vega is on the way??? Billy..

Guest a_appleby Posted July 18, 2011 Report Share Posted July 18, 2011 Here it´s the boot.img Don´t forget that yo need to edit the ramdisk, because i'm booting from sdcard, cu. rebel1 Hi, this is the system.img, that i boot from my sdcard. Iconia system.img It boots to the Welcome screen and prompts you to pick the language. The touch screen is broken. I put the IT* file in usr/idc.

Guest newbe5 Posted July 18, 2011 Report Share Posted July 18, 2011 (edited) Why? The touch screen is broken. This can be fixed, the important part is to see your ramdisk to see how you got this correctly booting from the NAND. All of my testing to get this working so far has failed, I have only managed to boot this kernel into Android by pointing the ramdisk to ext4 partitions on the sdcard. Everyone else has the same issues, as soon as you try to boot it from NAND it dies. Edited July 18, 2011 by newbe5 Link to comment Share on other sites More sharing options...

Guest newbe5 Posted July 18, 2011 Report Share Posted July 18, 2011 (edited) Please let me know how to fix it so I can actually test this. Well the first thing to try is to add the touchscreen config file, but you said you already did this? Adding this fixed the issue for rebel1. If you could please share your method for booting from NAND, I will try my best to help you fix the touchscreen issue! That way we have multiple people checking logs and seeing what the issue is :P EDIT: Nevermind I just got it booting from NAND myself :P At least partially! I was using direct blocks to mount, but for some reason that wouldn't work. Changed it to using mnt@system/data/cache again (and in the secondary init) and I' at least getting to bootanim now. Still not wanting to share your boot.img? Edited July 18, 2011 by newbe5 Link to comment Share on other sites More sharing options...

It's booting well now! Got some issues we need to work out, but it's getting there. Some confusing right now about the emmc settings, the sdcard blocks have changed from mntblk3 to mntblk0, but im struggling to get vold to mount them properly :/ Any suggestions?

Other than that, we are just trying to get Wifi working in the transformer image we are now using as a base, video acceleration and touchscreen work great though! newbe5 I would expect that. Remember that most tegra2 tablets have, in fact, 2 sdcards. One of them (the first one) is the emmc (just the internal storage, and it is just an sdcard directly soldered to the board, with no housing), and the other one is the external sdcard. The tegra2 hw has provisions for 4 sdcards, usually the first one is the internal emmc (not present on vega), the 2nd one could be anything, here it is the wifi adapter (it is an sdio card also without housing and directly soldered to the vega board) and the 3rd one is the external sdcard. As we know the 1st card is not present, the kernel assigns the mtblk0 to the first valid card, in this case, the 3rd. (and, btw, i do suspect one of the unpopulated connectors on the vega board is used for that extra missing emmc ;) -- Nice subject for a hw mod :) Wifi, i think that compiling the module with debugging messages enabled could tell what is happening there :) Regards, Eduardo Link to comment Share on other sites More sharing options...

The kernel, as compiled, will only support 48000. There are 2 possiblities here. Either we reconfigure the kernel for the other frecuency, or we reconfigure Android to use 48000 ... It was imossible to perform autoswitching between frecuencies, as the tegra2 chip also uses the audio clock to driver other peripherals, so, we can't change the SYSCLK frequency at runtime. Either we use the SYSCLK apropiate for 48000 sampling rate, or we use the SYSCLK for 44100. But the frequency can be changed only at boot time... In fact, i have tried both configurations, and it is not a problem to reconfigure the kernel... but.. 48000 hz seems to give higher audio fidelity :) -- If no other choice, i can reconfigure the kernel :) Edited July 20, 2011 by ejtagle Link to comment Share on other sites More sharing options...

I have a pared down version of the Transformer ROM I've been fighting with for a few weeks now. Billy.. OK, for anyone who wants to see where I'm at, this is a VERY ROUGH test build. Needs a lot of work (including sorting out busybox and toolbox properly). This is based on a fresh TF image and has a chunk of VegaComb applied (but not working correctly yet). Use the STANDARD 1.10 partition tables to boot this for now, I plan to change this in cmdline later to work with the moddedstock tables, but that's not so important for now. This may well change at any time, this isn't neccesarily what I'm planning on using, just what I'm playing with right now :) Have fun, grab it here, and in the interests of community, if you fix something, PLEASE POST IT! newbe5 Link to comment Share on other sites More sharing options...
Guest ejtagle Posted July 20, 2011 Report Share Posted July 20, 2011 Regarding wifi, the firmware that there is in the NVidia git should be used and should work. I think that i added to the wifi module source code package the instructions related to where the fw must be stored ...

Hi, the problem is not to compile the module or hack it into the load libarys. It looks like that the device cannot registered to the sdio. It outputs : <1>[ 359.657022] AR6000: HIFInit registering and nothing more, after that it should load the atheros blobs and set up the interface. greetings. rebel1 P.S.: I personally didn´t make any hc image.
