Is it possible to add and compile tslib into the kernel?

Using v03.03 of SDK.

Kind regards,

Follow the steps on this wiki to build the tslib package for the Linux Processor SDK:http://processors.wiki.ti.com/index.php/Processor_SDK_Building_The_SDK

At the end of the 'Build Steps' section use the following command to build tslib for the am335x (instead of building the full SDK for the am57xx as shown in the steps on the wiki):

MACHINE=am335x-evm bitbake tslib

The output of that command will be *.ipk files that you can install using opkg on your am335x. These files will be found in '.../build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/tslib/1.1-r0.arago1/deploy-ipks/armv7ahf-neon/'

Command to install:

opkg install ipk_name.ipk

Hi Jason,

Thanks for your quick response.
The bitbake seems to hang:

Currently 1 running tasks (109 of 356):
0: linux-libc-headers-4.4-r0.arago0.tisdk1 do_fetch (pid 12559)

It was in this state for like an hour.
Is this normal, or do I have some issues here?

Certain steps take longer than others but an hour seems too long for a single step. Were there any errors printed to the console?

I did not run into this issue when I ran the same command. Did you follow the network proxy suggestions on the wiki page that I sent earlier?

Did this at home and it worked fine.
I managed to compile it and then install on the target.
Thanks for your help.

Might be a network issue at work preventing smooth fetching I suppose.
Did not try the proxy suggestions section.
