have i killed my box ?

[Big Ted]

I have a nokia 2I bmon1.2 and spent most of yesterday trying to get it in to debug, i finally managed to get it to talk to boot loader using, and ppcboot, i type in the following
Type:
chorus 800000 [Enter].

cp 10000000 01000000 1000 [ ENTER ]

Nm 01000944 [ ENTER ]

0000000 [ ENTER ]

01000944: 00000000?
Press:
[ ESC ] [ ENTER ]

To turn off the Protection of the Flash Sectors:
prot off 1:0 [ ENTER ]

Changed RAM into the first sector copy:
cp 01000000 10000000 1000 [ ENTER ]

go 10000100 [Enter ] .

followed it exactly and then the box and pc did not reset just hung.


now when i turn it on i get no display on the lcd or tv screen.

the lcd lights up but no characters.

sorry to be asking questions on my first post.

any help would be great

Thanks

This method you have used is only for nokia with bmon 1.0

You have killed the BMon.

[DieMade]

The flash has to be reprogrammed externally.

[Big Ted]

ok thanks, any info on how to program it externally, remove the two flash chips i presume and have them blown with hardware.
thanks again

Ted

[DieMade]

Some information is spreaded in the board here, mostly in german.

It's not easy, so no simple HowTo available.

[Big Ted]

thank you for your reply. I have had a look with the search and can't find anything , i tried german phrases aswell, could you put a link to one of the pages that mention this so i know what to look for. or what to put in the search box. sorry to be a nussiance.
many thanks agian

[DieMade]

It's spreaded all over this board, I don't have any links or search-phrases in my (limited) memory.

Anyway, it's nothing one does/learns on one boring weekend

[Big Ted]

thanks man, I have found a few places that are helpful and a few sites that have the know how. if i can sort this i'll post a how to and how hard it is.

I got this a while ago but had given up due to problems, when the chips were reflashed they are now bmon 1.0, the old ones which I broken were 1.2, now the box boot into an image but can't read any of the scan files in it. it dosn't see the cables.xml and can't b altered very strange.
just wondering if the bmon makes a difference as to how the chip are read ?

thanks

ted

[DieMade]

The Box needs another reflash with BMon 1.2 - one must not mix the versions.

[Big Ted]

ok thanks for that.

[Big Ted]

can it be flashed like a new image or have i got to take the chips off the board again ?
thanks ted

[DieMade]

It can be on-board, but people tend to make a lot of errors during this progress. Without exactly knowing what he does, one shouldn't use this method.

I'll describe it in short terms anyway. You can't really "kill" the box, the worst result would be a killed BMon - and you already know what to do then

Download a yadd (you olny need "tftpboot/u-boot" for flashing now)

http://tuxbox.trale.de/atm/index.php?ac ... igma_LCars


Copy u-boot and your BMon-file (BMON.IMG) into the same directory (i.e. C:\FLASH).

Setup Bootmanager:
- Uncheck all Options
- Enter a IP for your Dbox
- Check "RARP-Server starten"
- Check "COM-Port" "Öffnen" - Speed 9600
- Check "BootP / TFTP - Server starten"
- Set "Bootfile für die DBox" to "C:\FLASH\u-boot"
- Klick on the "Start" button

- Power on the DBox, it should boot u-boot via network now.
- Press Strg+C as soon as u-boot starts up (ignore i2c-errors)
- uboot should show the "=>" prompt now
- Enter "rarpboot 120000 /C/FLASH/BMON.IMG" - the box should load the bmon via network
- Enter "protect off 10000000 1001ffff"
- Enter "erase 10000000 1001ffff" - this is the point of no return
- Enter "cp.l 120000 10000000 8000"

If everything went OK, your Dbox is back to live now. If not, its time for the soldering-iron

P.S.: Kids, don't try this at home!

[Big Ted]

thanks alot, i'll give it a go, now to try and find a bmon 1.2 image guess they are copyrighted so a bit few and far between.

Ted

[Big Ted]

got a bmon 1.2 what size should it be mines' 128kb is this correct ?

[DieMade]

1001ffff - 10000000 = 1ffff hex, 131071 decimal = 128kb

In short terms - 128kb ist correct

[Big Ted]

excellent, i'll give it a go and let you know how it all goes,

PS I hate soldering. . . .

Ted

[DieMade]

Hmm, others make a living out of it

[Big Ted]

got a problem, all went well until i typed this line,
cp.l 120000 10000000 8000

it then gave me the error, copy to flash . . flash not erased

daren't switch it off.

is it or not ?

tia

[gurgel]

you have to set the jumpers XH4 and XH6 to remove the Bootblockprotection of the Flashmemory.
or did you use the ppcboot 0.6.4? If yes, DieMade should tell you howto load and start uboot with that.

Do not turn off the Box until it says "Flashing Done"!!

[Big Ted]

so is it safe to switch off, no used u-boot. so if nothing has been erased then nothing programed either ??

need to switch off and bridge solder points then.

[gurgel]

the flashs have been erased! DO NOT STWICH OFF THE DBOX!

[gurgel]

please post the complete log of the comterminal.

[gurgel]

ok, the best way you do now, is to make a flash-reset.

drop the following pin uner the marked hole for a second to GND.

after that, erase the the flash again and enter the cp.l....
then it should work.

AND DO NOT TURN OFF THE DBOX, before Flash is not complete!
