U-boot sources from c series find how to cross-compile it?

[Mkò]

Hi to all developer i found uboot sources for c series tv and i download the cross-compile environment from svn but i don't know how to cross-compile can somebody help me?
another question i have source only for uboot is the onboot sources needed too or not?
my idea is to cross compile uboot from sources then calculate proper hash with the tool that are available here and then flash it to my tv with bml.restore.

1. onboot is locked on C series, and you can`t overwrite it. It has write protection, probably cotrolled trough GPIO pins. Here are some ideas to unlock it by removing some resistors on mainboard, but we don`t know which and if it is right way at all.
2. u-boot partition is empty and even you compile uboot, we don`t know if code to enter u-boot isn`t removed from onboot. Means - same as on B series CI+ devices - here is no pause to hit any key to stop autoboot left. As result - no entry to uboot promt.
Another danger here - IF u-boot partition is being checked during start, changing it can lead in to the brick. Okey, this is less possible, but you have to keep in mind this kind of brick.
3. you need flash not only u-boot to /bml0/2, but also proper uboot.env to /bml0/3 and uboot tools to /bml0/4.
4. For E series you can compile using toolchain from svn

Code: Select all

svn checkout svn://svn.code.sf.net/p/samygo/code/develop/toolchains/T-VAL

or from samsung opensource (arm_v7_vfp_le_20091117)

onboot is locked on C series, and you can`t overwrite it.

So i can overwrite only uboot to bypass this problem right?
the protection of the onboot is the otp lock of service menu?any research about the otp lock of service menu?maybe change the otp lock from 1 to 0 o from 0 to one in service menu can disable this lock or not? i think need more research.
I've find the uboot sources in le40c630.tar.gz.
I also find that the c series is also called Aquila and in one file "dtv_bml_aquila" from onboot-src-Firenze2011.tgz there is such a map of partitions and loader. so maybe the onboot of firenze platfrom works for valencia too...? or not? confusing.
i have the sources from c series and the toolchain downloaded friom samygo svn.
but i need some hint to cross comiple the sources that i've.

First check if your compiler works. Compile kernel and modules from defconfig....

ok i'm trying to use the info that you post here ->viewtopic.php?f=49&t=5999
so i get the toolchain for c series from svn
i copy it to opt dir
I download the sources UE32C6500 (Now i don't know why now the sources for c series are all missing from oss site... ... ... )
but of course i can't find "VDLinux_2.6.35.11.tgz" so i use the file Linux.tgz that i think is same as "VDLinux_2.6.35.11.tgz" and as you say i extract it to /opt/src/ but now i'm stuck because i don't know what file i have to copy to the root of toolchain
(my toolchain is arm_v7_vfp_le_20091117 so i have to copy the file in this dir right?) my tv is valencia aquila and in /opt/src/linux/arch/arm/configs/i find the file aquila_defconfig is this the file that i've to copy to the root of toolchain?
can you explain these steps
"and copy default config for your kernel to root of sources and rename it to .config

Code: Select all
cp -ar arch/arm/configs/X10P_defconfig_release .config
cp -ar arch/arm/configs/X10P_defconfig_release .config.old


4. export path to your compilers bin dir (or add to ~/.bashrc at the end), re-open terminal to use new path.

Code: Select all
export PATH=$PATH:/opt/VDLinux-arm-v7a8v2r2/bin"

[sbav1]

my tv is valencia aquila and in /opt/src/linux/arch/arm/configs/i find the file aquila_defconfig is this the file that i've to copy to the root of toolchain?

Yes - however there is really no guarantee this exact kernel config file is actually fully appropriate for your particular TV model. Usually there are at least two config files for given platform (*_debug and *_release) and sometimes the (proper) .config file allready exists in root directory. But never mind, it should be good enough for test purposes.

Samsung doesn't really believe in due diligence while creating those instructions; they just copy & paste some text fragments from previously created "howto" files, often intended for completely different platforms/models.

I think I have default config for Valencia...

right the info0 provided by sam sucks...
the problem is that i'm confusing with all these infos...

I bet for valencia

[sbav1]

So i can overwrite only uboot to bypass this problem right?

Not likely, because the primary bootloader (onboot) flashed in "production" models usually does not contain the code fragments needed for loading uboot (== secondary bootloader) - for that function to work, you will probably need onboot recompiled with DEVEL/DEBUG #define[s] enabled. At least that's how the things are in later models (D-Series and up). In Valencia/Aquila C-series models it may be different, but I find it rather doubtful.

the protection of the onboot is the otp lock of service menu?

Once the OTP lock protection is applied to OneNAND/FlexNAND boot block[s], it is (by design) basically irreversible (generally speaking; perhaps there are some clever workarounds etc., but I'm not aware of any). Regarding an option in service menu called "OTP lock" - I don't know what it does exactly in this model; there are 4 possibilities:
1) It does enable (most likely permanent) OTP lock on flash boot block[s],
2) It checks & displays if the boot block is locked or not,
3) It doesn't do anything at all (quite an common occurence for various service menu options in Samsung TV & BDP gear),
4) It may be not intended for OneNAND/FlexNAND flash boot area at all; there are other one-time-programmable subsystems in SDP92 SoC, not to mention the other onboard chips.

BTW, there was some kind of tool (fsr*boot*, fsr*util*, fsr*tool* ?) or something like that in B650 models, it has the command line switch to check if the NAND boot area OTP lock is indeed enabled or not. It may be worth to check if it is actually locked or not in your TV - I'm not quite sure this lock was enabled by default in all C-series models (at least not originally). But better be careful with it - AFAIRC, the same utility was used to enable the permanent OTP lock (with different command line switch).

I've find the uboot sources in le40c630.tar.gz.

Is it uboot.tgz, 4 259 723 bytes long? If yes, I have some serious doubts if this is a proper uboot release for Valencia C-series. It looks like an uboot for much older (pre B-Series) Samsung Bayhill/SDP76 platform.

I also find that the c series is also called Aquila and in one file "dtv_bml_aquila" from onboot-src-Firenze2011.tgz there is such a map of partitions and loader. so maybe the onboot of firenze platfrom works for valencia too...?

Extremely unlikely. While there are numerous references to SDP92 (Valencia) in Firenze 2011 onboot sources, it's just because Firenze onboot was not written from the scratch, developers reused many code fragments from previous/different versions. This thing has a complicated ancestry, it borrows from armboot/uboot code itself, linux kernel mmc drivers etc.

BTW: I can't find "dtv_bml_aquila" file anywhere in Firenze 2011 onboot sources (?). There were two (slightly different) releases of this code from Samsung I'm aware of; perhaps you have some different version?
