Hi Robert.
I have got BBB and wired in RS485 receiver (MAX13487EESA+, has got auto
redirection).
Started to do test with libmodbus and that I have found out that I need a
RS485 patch for my BBB.
My original kernel was 3.8.13-bone56.
I found your git repository for linux-dev for version 3.8.13-bone53.
There are many patches listed there (including RS485) so I thought, ok,
would be nice to have them all.
I have installed this kernel using:
wget https://rcn-ee.net/deb/wheezy-armhf/v3.8.13-bone53/install-me.sh
then I did:
git clone git://github.com/RobertCNelson/linux-dev.git
copied system.sh sample to system.sh
then
git checkout am33x-v3.8 (I have no idea what it does)
then ./build_kernel
First I had some problems with xt_tcpmss.c and some other files, error
saying that I have modified them already :) yeah, right, would be nice if I
could :)
but have entered KERNEL folder and typed:
git reset --soft HEAD^
git stash
(found on some website, have no idea what it does)
that solved this problem but when your script starts patching, I have got
error just at the first patch:
Applying: Without MACH_ option Early printk (DEBUG_LL)
error: arch/arm/mach-omap2/Kconfig: does not match index
Patch failed at 0001 Without MACH_ option Early printk (DEBUG_LL)
When you have resolved this problem run "git am --resolved".
If you would prefer to skip this patch, instead run "git am --skip".
To restore the original branch and stop patching run "git am --abort".
I even edited patch.sh and commented first pacth, then build_kernel process
fails on the second patch.
I spent 4 days crawling through internet, building, stashing, cloning
almost everything you have got on github and I couldn't make it work.
It would be nice to have ./build_kernel working properly, but It looks like
am not skilled enough to do this.
It is very nice to receive reply from you. Will it be possible for you to
guide me through ./build_kernel.sh process?
Any known website which explains it completely?
What I would like to have is the most up to date kernel for BBB (with cape
manager) alongside with the patches that exist and are not implemented in
this kernel.
Thank you
Artur
P.S
I thought that for RS485 it would be nice to download any image which have
all patches included.
I will then face another problem in the future as I need to test CANBUS and
J1939 stack, so back to build_kernel.sh again.
that is what I have got:
