Stuck at freeing init memory 124K

Other Parts Discussed in Thread: ASH

I'm trying to boot my TI6614 board using NFS kernel. Posted below are the bootlog and the screenshot of the minicom session. Thank you.

PS: I have already tried including init=/sbin in my nfs command. Doesn't seem to make a difference.

Sounds like EABI incompatibility between filesystem and linux kernel.
Disable EABI support in linux and check.

Refer to the following e2e post.

Hi Titus,

Should I add this in bootargs then? CONFIG_AEABI=n

Because I added it to the nfs and tried already

0 Titusrathinaraj Stalin over 9 years ago in reply to Dipak Narayan

TI__Guru** 116100 points

No, you have to add it in the Linux kernel configuration.

0 Dipak Narayan over 9 years ago in reply to Titusrathinaraj Stalin

How do I do that? Just add the statement in the Kconfig file?

Is there any guide online which I can refer?

0 Titusrathinaraj Stalin over 9 years ago in reply to Dipak Narayan

TI__Guru** 116100 points

Nope.
Go to linux kernel source and do "make menuconfig" then search for "EABI" support and disable it (say 'n')

Hi Titus, I get this error in that case

It seems you are doing this with desktop PC linux kernel source but you have to do the same with your EVM board's linux kernel.

Have you downloaded the linux kernel source code for TCI6614 and its toolchain ?

cd linux-kernel
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
---> Kernel features
-------> Use the ARM EABI to compile the kernel (Say no here or remove the support if not)

Hi Titus,

I don't think I have the kernel source codes. The directory usr/src in my EVM linux in empty.

Is there a link for it?

PS: Sorry for bugging you with these questions, but I'm new to TI SoCs and some other intern booted the Linux to the board.

TI__Guru** 116100 points

Can you please tell me where did you get the boot images (u-boot, Linux and filesystem) for your board ?

0 Dipak Narayan over 9 years ago in reply to Titusrathinaraj Stalin

I'll need to get in touch with the other intern regarding that. I did some googling for the kernel source code for the 6614 and came across this link. Can you please see if these are the kernel source codes. Thank you.

Yes, you can use this kernel too.

Download the kernel & toolchain(arm-linux-gnueabihf-) and build with below commands.

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tci6614_evm_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage

You would find the kernel image from "arch/arm/boot/uImage"

Thank you Titus,

Sounds like a lengthy process. I'll do it and get back to you

Hi Titusrathinaraj Stalin

I got the linux kernel images from the sc_mcsdk_linux_2_02_01_03 and booted linux kernel in the EVM using the TFTP server.

I couldn't find kernel source codes in /usr/src

So should I rebuild the kernel source code, run make menuconfig (in the host machine) and load the u-Image in the EVM using the TFTP server? (Because there isn't enough space in the EVM to install the cross compiler)

So should I run make menuconfig in the EVM, if yes then where? Here's a screenshot of my EVM root directory

Thank you

No, you won't find it in EVM.
You have to install the MCSDK package in your machine and you would get the kernel source code and filesystem & toolchain etc.,

I got the linux kernel images from the sc_mcsdk_linux_2_02_01_03 and booted linux kernel in the EVM using the TFTP server.

Where did you download the "sc_mcsdk_linux_2_02_01_03" package ?

Also, your original question was you are not able to mount the filesysystem and you did it with pre-built images from the downloaded sc_mcsdk_linux_2_02_01_03 package.

So I am closing the post, let start new post if you want to know how to build and configure the kernel,
