UBL is setting up the flash timings (A1CR) and so far U-Boot
was overwriting it with a timing for the EVB development board
of TI. Let UBL define ECC/ChipSelect and the A1CR timings.
This might now cause different kind of flash issues because the
per chip timings might be "wrong". This is why this commit should
needs to stay in testing a bit longer. We should use this commit
on RevC, D, E and F hardware ourselves a bit.
I didn't know that u-boot was creating a package and installing
the bin into /boot. The detection of the file seems to have
changed and a new QA error comes up.
ERROR: u-boot-v2011.12+gitAUTOINC+f6453a3911-r0 do_package: QA Issue: split_and_strip_files: 'file /home/oebuilds/jenkins/workspace/Yocto-Master/label/OE/build/tmp/work/sysmobts_v2-poky-linux-gnueabi/u-boot/v2011.12+gitAUTOINC+f6453a3911-r0/package/boot/u-boot-sysmobts-v2-v2011.12+gitAUTOINC+f6453a3911-r0' failed [split-strip]
This seems to have been introduced by changing the LC_ALL to
en_US.UTF-8. I have started a dialogue with upstream development
but as we do not need a u-boot package, let's just remove the
files.
I think the last device we sold was in 2011 and I am not aware
if anyone has used it for the last couple of years. Remove it
to lower the complexity of the builds.
Now reading the command it should probably be add.nwp or
rem.wp but so is life. We can add an alias for add.nwp in a
future version. The boot, recovery and fwup command have been
changed to issue nand rem.nwp before touching the flash.
Let's flash multiple copies of UBL and U-Boot to cope better with
NAND bits flipping in these sectors. To fit multiple copies of
U-Boot into the flash we had to move the rootfs a bit to the end.
We do not intend to use u-boot right now but at least this
version will build. In the first version we will use the
barebox images provided to us by the producer of the SoM.
The build differs in that it doesn't use a getty on ttyS0. In the fuutre,
a modified kernel serial driver as well as a 2050-specific utility
for managing the supervisor processor will follow.
The idea is that the basic extension resides inside the the normal
recipe directories. Depending on the version of poky the bbappends
need to be included. Appends applying to all versions will be put
into the shared folder, specific ones into the specific directory.
Once a bbappend can not be shared anymore it needs to be copied.
