[Q] Clockwork...DesireHD...NAND...Ext4-SD? Arrrr

OK, not that much of a noob (or at least dont think I am!) have been playing with android for some time, and have decided to cook up my own rom based on DesireHD. After some failures I now have a good stockish rom that I like and will release once i can sort out a few problems that I have.
I want to go down the CWM .zip route so I can release updates easily, off to the forums I went with a few questions... hours and hours of searching and researching and a few test runs later... have even more questions!!!!
1. EuroHD2 (Leo512) has 512mb ROM > how much of that ROM is actually available?
2a. When does the kernel load the SD-Ext partition?
2b. With CMW Recovery do you have to set a "userdata" partition when using SD-Ext data, or can you get away with not setting one?
3. Does CMW support using SD-Ext userdata
4. Is the 400m CMW Recovery only for the Leo1024?
5. What is the maximum size for the "system" partition on Leo512?
6. What is with all the questions??????
As you can see, many questions. Most have come from searching the forums and becoming more and more confused with it all!!
Please help!

All of it.
Partitions:
misc 1MB
recovery 5MB
boot 5MB
system 150MB to 350MB
cache (optional, but people like 10MB)
userdata (whatever that remains, 350MB system partition size = 50mb userdata)

yes, sadly, you still need the userdata partition, you can go around it by creating another partition on the SD card, and call it userdata, I am assuming that works too. So now your SD has userdata, sd-ext, fat32 partitions.

urm, that's not CMW's job, that's your job.
You can either use DATA2EXT method which puts all userdata in SD card, ext2/3/4 partition or A2SD+ which puts all your data on the SD card, minus I don't know what, because it keeps reducing and I never figure out what. I am lazy to use adb.exe to go check.

Yes, because you really ran out of space. 350MB system partition, gives you less than 50MB of userdata partition provided you have 10MB of cache partition.

I was wondering that...
So if I create a "userdata" partition on the SD card the system should use that... meaning no userdata partition on the NAND... meaning SD-Ext and Data2SD features are not needed?
But then surly if it was that easy somebody else would have done it?!
The layout I am thinking is:
NAND/
--/misc (1mb)
--/boot (5mb)
--/recovery (5mb) *Is this needed? - Is this not for the recovery programs that we have on SD?
--/system (350-400mb) *theoretically upto 491mb as no userdata on NAND
--/cache (10mb)
SD/
--/userdata (1gb) *Could be bigger, but have read that it can cause corruption if over 2gb
-Fat32 (leftovers)
But all of this comes back to Q2a. When does the kernel load SD partitions?!
Other idea is to set the "userdata" in NAND to set size and grow the "system" partition and carry on using SD-Ext and Data2SD for internal storage, something like:
NAND/
--/misc (1mb)
--/boot (5mb)
--/recovery (5mb)
--/cache (10mb)
--/userdata (50mb)
--/system (leftovers) *441mb
SD/
--/Ext (1gb)
-Fat32
But then does the "system" partition have to be created 4th and wont work if created last???? And what about all the plastic trees, where do they go?! My head hurts, i'm cold and there are wolfs after me!

I am guessing that creating userdata on sd card might work, but I don't know how your build mounts partitions, so that is your job too.
but you should read up on data2sd, data2ext, a2sd+ and a2sd
No, you can move the partitions around, it worked for me.

[Q] question about cache partition.. and system

Ok, now im wondering, is the cache directory in system supposed to be connected to the cache partition that gets flashed in some roms?
For example, say i look at my root dir on my phone, i go to data and it lists the used and free which combined, is the auto sized amount of my data partition, if i go to system,the used and free combined is tha size of teh system partition i have (i used cwm and in my case its 410M) now i flashed a cache partition (of 10M) so i had assumed that the cache dir in root was linked to my cache partition, so the amount used/free combined would be 10M, but instead its the same size as of my data partition.. so i know that its using that partition instead..
is it supposed to be like that?
what use is the cache partition?
also, does anyone think there would be a benefit if the system partition was in ext3 format instead of yaffs? i know that most oem roms come with the system partition set in ext3 format, would that ever be possible with magldr?
thanks.

Anybody got 2 cents they can throw in?

cmon, any answer at all would be nice from anyone..

It looks normal to me. Most sense builds i saw here, dont use the cache partition, instead the data partition is used. So basically you could flash a 1mb cache partition and it will work and you get some more space for system.
btw, on nand there is allways yaffs used for system, not ext(X).

Use of cache partition are depended on the Android Builds. Most builds do not use cache partition at all. /cache is redirected to /data/cachemnt on the userdata partition. However cache partition is required for CWM. It will compliant if cache partition is missing.
ext2/3/4 are not suitable for NAND Flash. YAFFS2 is develop for and more suitable for NAND Fash Device. However, there are ways to use ext2/3/4 though other methods. (one of them being loop device mount) and for Read Only. Each method has its pros and cons. it really depend if the benefits outweights its drawbacks.

hey first, THANK YOU for commenting. ok, thats interesting, i have always seen it suggested to use a 10 -40 mb cache partition, ive also heard that market can have some weird effects such as not being able to download if the cache partition was too small.. thats why i assumed that it was used by the system in some way

i asked that since i have seen most of the oem roms using ext3 and assumed it offered some benefit speed-wise. all phones use nand of the same type yeah? so whats the benefit of using ext3 when yaffs2 preforms much better on it?

[q] cwr 5/250/5 ?!!?!

People, please make me understand what is CWR 5/250/5 & how to do it?!
Does it has something to do with the SD Card?! And what if I have only 700MB out of the 8GB, would that hurt this CWR?!

its the partition size needed for the rom to work correct
1st number is the boot size required
2nd is the system partition
3rd is the cache size

Can you please help with the steps to do that?!
2ndly, would it harm if my sdcard has only 438MBs left out of the 8GB?!

Internal partition, nothing to do with your SD card. Go get the nand toolkit, cwm partition, select 250 done.

Here you go
misc ya 1M
recovery rrecov|ro|nospr filesize recovery-raw.img
boot yboot|ro 5M
system ya 250M
cache ya 5M
userdata ya|asize|hr allsize
copy paste this into your cwm in the flash.cfg (open it in notepad)
then flas the cwm via usb flasher in magldr (i assume you know this)
its just like flashing any daf rom !!

how to partition 5/155/5 internal ?

I want to try a ROM which says:
Partition Layout (5/155/5) use hd2 toolkit
SDext: min. 500mb
I am not 100% sure what does it mean SDext is probably 500 ext patition bigger than 500
5/155/5 is
5 cashe
155 data and
5 WHAT????
Cant figure this out.
Thank you

Do you have any android rom installed? If yes, then you should (I had on every rom) have an option on reboot menu: reboot, recovery and BOOTLOADER - choose this one. And there you have SETTINGS->REPARTITION NAND and there set these ones your roms prefers. If you have not, then try to install this rom choosen by you, and maybe there will be option BOOTLOADER on menu. These are partitions, for example 155data(system) is space for system (I think). But standard settings are good for me and works with every rom.
[EDIT]
Try to boot phone by holding [back] nad [Power]. This opens bootloader and there you can set all.

Partition your nand using HD2 Nand Tookit.
First 5 is boot partition set to 5 by default
155 is system partition,
next 5 is cache size.
sdext partition can be set up from recovery (in cwm recovery go to advanced menu and select partition sd card), follow instructions for your rom. This can be used as if it was internal memory by your rom..
ALSO you might want to take a look HERE..
Edit: best to post any questions about any specific ROM in the ROM thread

This question was not "how-to", but more "what does 5/155/5 mean" type of question. Last time I played with internal memory of the device all I had to do was select the appropriate CWM version. This is why I asked here, I think it belongs, cos is general knowledge kind of thing.
I kind of dont see how to fiddle the size of /boot, no problems with /data and /cashe, but since you say this is default I wont have to, I suppose.
A few days ago I was pissed of by CyanogenMod (and stock Andriod in general), cos the only option to deal with Vcards is Handsend sms, but Handsend will not search for contacts correctly in Bulgarian (CYR) when installed on vanilla Android - small letters will not match capital and vice versa in contact names. This is why I decided to go for Sense - the message app is simply better...

Rather than using toolkit, download the CWM package and inside is a file called flash.cfg. Open this file and you should get this (maybe a different system or cache size)

5/155/5 is basically the middle three lines, i.e. 5Mb boot partition, 150Mb system partition and 5Mb cache partition. I don't know why chefs post it like this as I'm reasonably sure the boot is always 5Mb (I've never seen differently) so they could just post the system partition size (as quite a lot do). Hope this helps

You can use CWM Recovery it's very easy to use for repartition your nand, but you must install MAGLDR or CLK first if you want go to recovery..

Hm, this is something I missed!
1. I use mainly Ubuntu, hence I have have to rely on Wine or a pc I almost dont use for windows
2. I have CWM and MAGLDR installed
How to re-partition based on config file only? Can I do it?
Put the config where? (sdcard, ROM.zip)
Run what in CWM.
You would make my day, since I am away form how, with my laptop only, the ROM I run has a bug with wifi tether and I have to change it, but options are quite limited, since I dont know how to re-part, I have to choose ROMs that rely on system less or equal to 155 at teh moment. And I need a Sense, since others cant receive 100% vcards in Bulgarian (CYR)

eiy seems like AOKP but using HD2Toolkit, min. for cache is 5mb, try the link below it could give you an idea

Installations:
Please use at least 170MB system partition and at least 2MB cache partition.
Please refer to ksubedi's HD2 NAND Toolkit and/or mskip's guide.
Cache partition (/dev/block/mtdblock4) is only mounted and used by CWM.
Cache partition size is not important because the data partition (/dev/block/mtdblock5) is used as the cache space when running Android.
If your HD2 has bad NAND blocks, you may need larger partitions.
Wipe
Wipe Data/Factory Reset while doing a fresh install. (Optional: also delete /sdcard/Android folder or format your SD card if you have any strange issue.)
Advanced -> Wipe Dalvik Cache while upgrading from an old version and wanting to retain data.
Flash this ROM.
I click custom and below that enter 2 in cache box, click repartition. Show new table "What do you want the custom partition size to be 5-445 MB allowed. I write 170 click OK.
I give table sorry chase size must be 5 to 45MB.
Where is I did mistake ?

1 -In the main HD2 android NAND toolkit window, look left for "Choose system partition size(MAGLDR)" and select "CUSTOM"
2 -Below this window change "cache size", but smallest possible is 5MB. It doesn't matter if it's bigger, won't give trouble.
3-after those step choose "Repartition" button below 'Functions' and type desired (4) system partition size.
Have fun.

as retsam88 said, it deoesnt matter the cache size, most people leave it at 5, some roms say 45, (but i haven't seen that for a while).
As far as i know, (i've read it once or twice) on most roms, only recovery uses the cache partition.

misc ya 1M

I like to do this partition. What do i have to make it work with hd2toolkit ? Thanks

you cant because the toolkit writes a new flash.cfg each time when you choose custom, or uses an .nbh when you choose a preselected size.
You should find the daf.exe flash version of cwm, and when you extract it into a folder you will find one file called flash.cfg, , open that in notepad you will see a list like teh one you posted, , edit the numbers, save it, then run daf.exe with teh phone in usb flasher mode.
