Hello,

Is there any reference document that shows how can we port openWRT on AM5726?

Need to add any kernel support?

What change will be in the file system?

Please do the needful.

Hi,

This is open source software, not developed or supported by TI. I suggest you look in the https://openwrt.org/ resources for information or support regarding this.

Hello,

I need just small help to narrow down the problem.

I have compiled the file system of openWRT and it is ready to use.

I changed pre built SDK file system with openWRT file system.

But kernel stops at "This architecture does not have kernel memory protection", So do I miss any option to enable from the kernel side.

Please do the needful, I know TI is not providing support of openWRT but this is related to kernel of AM57xx so it will be great help if you give some guidance to me.

Regards,

Hi,

You need to modify the kernel, so that you have the CONFIG_DEBUG_RODATA enabled. See init/main.c

Also which kernels are you using? Latest TISDK, which uses kernel 4.9.41 has this feature enabled:
CONFIG_DEBUG_RODATA=y
CONFIG_DEBUG_ALIGN_RODATA=y

I am using 4.4.32 version of the kernel.
I will try to apply this setting and check it out.
Thank you for helping.
