Other Parts Discussed in Thread: AM3517

Hi dear all!!

I got the RTLinux source from the GIT source directory "linux-omap3-2e07da26756f772bdfdca4ae85ca3097c96ff76c.tar.gz"

from the following source <http://arago-project.org/git/projects/?p=linux-omap3.git;a=shortlog;h=refs/heads/int_omappsp_v2.6.33.7>

My first question is this kernel Patched.

or i need to download a patch for this if yes which patch i should go for.

I am compiling this kernel as follow

1.Download the RTLinux kernel Source.

2.Extract the Kernel Source to the directory /usr/src .

3.if the Kernel Source is Not patched – Patch the kernel Source.

4.make mrproper. [To delete all oldconfig.o file]

5.make ARCH = arm menuconfig. menuconfig for graphical configuration.

6. make dep

7.make bzImage or make ARCH=arm CROSS_COMPILE (can any body explain this command wrt am35xx how should i implement and what settings do i required).

8.make modules.

9.make install.

till step 5 i have done , but it starts giving error after step 5.

I am using Linux platform : Fedora 14.

How should i create an image??

Hi Hrishikesh,

This kernel tag already has RT patches. Please note that these are applicable only for AM3517.

Please follow the steps listed below to compile the kernel.

Hi!!

Thank you very much for your response!!

Dear sir,

I am using TAM-3517.

Now I have compiles both the Kernel sources available on

http://www.technexion.com/index.php/support-center/downloads/arm-cpu-modules/78-tam-3517

and the GIT source http://arago-project.org/git/projects/?p=linux-omap3.git;a=shortlog;h=refs/heads/int_omappsp_v2.6.33.7

Now i have Both uImages with me one is General TAM-3517 kernel source image and the other is RTLINUX image. I need to test them but i dont want to mess up with current ported Android Os in TAM-3517 & i am wishing to boot these images through SD - CARD .

I have some Doubts :

1.On power On ROM BOOT CODE executes.

2.Fetches the First Stage BootLoader (X-loader ) and executes in internal RAM.

3.Which in case will have the address of Second stage Bootloader and will execute this in external ram to boot the OS.

4.Now these BootLoaders are stored in NAND FLASH.

Similarly How can I configure the x-loader and Boot Loader to boot from SD-CARD.

I tried to search but didnt found the correct link...

Please help to build and configure the bootloader and boot images from SD-CARD.

the TAM-3517 has hardware configuration to boot from SD CARD and avoid the NAND FLASH.
