Nand replacement

[duggy]

Just noticed that patch is in the duo dir, i'm working with UNO so it might not be relevant anyway...

In case someone has the same problem... the solution is to...
Edit the Makefile that runs mkfs.ubifs so that it uses the right setting for the "-e" option, which is computed by this formula:

LEB_size = PEB_size - ((Subpage_size + Page_size)) / Page_size) * Page_size
(In the division, keep the integer part)

Also make sure you use the right setting for "-c" ("Amount of eraseblocks")In ubi.cfg, make sure you use a "vol_size" that's smaller than the actual size of the partition on the NAND to leave room for Ubifs internal data. With "vol_type=dynamic", Ubifs will end up using the whole space automatically

Perhaps insufficiente to configured the right -e parameter. You should be near to success..

Thanks, i just reflashed the working arabic image so that i could telnet in a dump mtd info. going to see if based on the output i can figure this out, wish me luck

Hi i think I know the right values to use, but i cant find the file i need to edit/adjust. Can you tell me which file I need to use for the updated values?. I dont think there is a "mkfs.ubifs" in openvuplus environment ?

There are thousands of files so finding the right one to update is very hard

However you should mtdinfo mtd0 (rootfs) and you should modify the eraseblock of previous bb file with the one you get from the working image. If speculation are correct, after new image build you should be able to boot your box.

At work now but when i get home i'll try this..... so excited!

 

[duggy]

after lots and lots of compiling I'm still struggling

I was unable to find that fille in the openvuplus repo but i DID find it in the openvix repo.

So i cloned that and it wouldn't work because my paths were too long, I fixed that too and finally able to build an image but I cant finish the compile because of the PEB size issue

The image that boots has no mtd_info app but here is contents of /proc/mtd

Now I tried to make an image with 288 PEB as per output from latest image but the compile fails

ERROR: Error: The image creation script '/oe-alliance/builds/openvix/release/vuuno/tmp/work/vuuno-oe-linux/openvix-image/openvix-image-3.2-r20150905160443/temp/create_image.ubi' returned 255:

I searched internet for ANYONE with ANY system (just just a STB) with this nand and I found this (this is NOT my system, but it is useful to see info about this chip I fitted)

They have no PEB than me with the same chip, must be calulated based on values passed to mkubifs. So I am stuck now, cant make an image with "-c 288" as it wont compile

HUGE UPDATE! (good news)...

I have almost a fully working system. I can make an image that boots fully, i can ssh in and everythingm problem is there is a background process that starts to clean up the nand, and that process breaks the box

Still this is a HUGE step forward

while the system is working (and before that background process messes up the nand) I got MTD info native on the box running ...

output from "mtdinfo -a" attached (mtd.txt)
dmesg attached (for more juicy info) ...lol

 

[duggy]

Time to edit message expire....anyway the final issue to resolve.. there is a repeated message I'm unsure how to resolve, this is the repeated block constantly on the serial console. Any ideas what its telling me?

actually maybe that background process is not the problem or the process that is going "bad", something else is? (notice free space cleanup completes)

UBI: background thread "ubi_bgt0d" started, PID 50
ata2: SATA link down (SStatus 4 SControl 300)
UBIFS: parse sync
UBIFS: background thread "ubifs_bgt0_0" started, PID 51
UBIFS: start fixing up free space
UBIFS: free space fixup complete

...

also errors always seem to happen in same upper range.

Feast your eyes on this!




Ladies and gentlemen, the box is FULLY recovered and using the new Spansion nand

The problem is that the vu kernel is working out the eraseSize incorrectly. I've hacked the openvix code and hardcoded the right value in the src code. Its working great now

Maybe this will help someone in the future...

Very big Respect i like you, but it's not just because you did it, it's because you don't gave up!
I know how it feels when you never did such H/W related things, after every little successes the next problem comes across.
I had big problem's and almost got crazy at a simpler thing, desoldering and reprogramming an EEPROM with a corrupt bootloader.. it was a total nightmare for me!
You have all rights to be proud on you

hahah yes. i didnt have the heart to throw away the box. Its not a new box, its not the latest box but I knew the faulty part was so cheap < 5 euro that it seemed crazy to throw the box away. Lots of learning, and lots of reading. Baby steps and a VERY BIG help on how to compile the Kernel in Linux from a helpful user on the openpli forum (betacentauri) who show'd me how i compile just the kernel (in the openvix build environment). I hacked the source for myself. Not pretty but it works

The problem is that the linux kernel from vu that gets pulled down as part of the oe-alliance build has a file that determines how to use the nand. I inittially went about this wrong trying to fix the openvix distro to work with 512K pages, until recently I decided that was the wrong way, the right way was to fix the linux kernel to detect the chip right. I'm not skilled enough to fix the source code correctly so did a dirty hack in the source code, it works fine so thats all that matters.

Had to also learn how to remove and fit a TSOP48, also had to learn about using BBS3 to program CFE to the blank chip. If ANYONE needs help doing any of this, I am here and happy to help and answer all questions

IF anyone has the same box and the same problem, you need to replace the samsung nand with spansion S34ML01G100TFI000. It cost me £12.77 delivered for 7 units (i only needed 1 but they don't sell singles). This is from RS if you in are the UK, their part number is 8096961

I also had to buy a hot air rework station, but you can probably do this with Just a soldering iron, but I wouldn't advise it.

You also need a cypress FX2LP board to talk to the broadcom SOC to program the CFE on the blank. chip , this is £4.50 on ebay

Like a wise man said, "Everything is possible"
All the things you did and all the little pieces together are part of your your success..
It doesn't matter was it the "right" or "wrong" way you have chosen to follow!
At the end everything that forced you to nearly give up is on the other side the main thing that pushed you up and gave you more and more reasons to MAKE IT..

That's how I feel about such challenges and I'm pretty sure that @duggy feels the same

You solved yours, it's time that i solve mine.. Getting ready fight
