Software support
In order to tune DDR3, a RAM-only version of u-boot was created. This u-boot is totally stripped down to basically an interactive shell with few features. A set of calibration access routines were added:
tmd - memory display for tuning tmdel - delay calibration tmrr - read data and checksum from write tmtest - simple RAM read/write test tmw - memory write (fill) for tuning tmw2 - memory write (fill) for tuning, ignores trailing data tmwcal - write calibration tmww - write random data to RAM
Routines like tmrr and tmww just generate traffic to trigger the scope.
tmwcal and tmdel perform the DDR3 calibration routines, per Freescale application notes.
Currently, all the other shell routines break because global/static variable storage is broken. u-boot really tries hard to relocate itself to a new location in RAM, which I don't need it to do. Right now I just jump out of board init and call the interactive shell directly, skipping the board_init_f function which does the relocation. The only thing I'm really missing is hush functionality (which makes up-arrow work) but in the end I decided it wasn't worth the debugging to get that piece working.
To build this special u-boot, do the following.
Check out the tree:
git clone git@github.com:sutajiokousagi/u-boot-imx6.git
Set up the environment (as necessary per toolchain, this is for the OE self-built chain):
source /usr/local/oecore-x86_64/environment-setup-armv7a-angstrom-linux-gnueabi
build it:
make clean; make novena-ramtune_config; make
This should result in a u-boot.imx that is about 80k in size. It's targeted to load into OCRAM at address 0x009073e0. You can grow the image up to about 160k or so in size and it will still work.
burn it:
sudo dd if=u-boot.imx of=/dev/sdX seek=2
This locates the u-boot onto the SD card into the location expected by the initial bootstrapping ROM.
Bringup notes
First, it's important to note that it's impossible to write-level calibrate any memory made by Micron. This is because Micron only mirrors the calibration clock to DQ0 of each memory. However, other manufacturers, such as Kingston and Samsung, mirror the clock to all lanes, allowing for such calibration.
That being said, it was possible to collect calibration runs from several devices.

Errcount is zero, and the trivial write/read test seems to work with these parameters.
Note above that the errorcount is 0 on this run.

Other Notes
Measurements performed using TDS5104B 1GHz oscilloscope with dual active P6245 probes:
- probe 3 has about a -5% full scale offset (1.5V reads around 1.45V)
- probe 4 is pretty much dead on
drive strength on A5 looks fine with 60 ohm setting (0x20)
setting of 0x38 improves margin by about 90mV. Tiny overshoot seen. slight improvement in slew rate
conclusion: set to 48 ohm, 0x28 --> looks best here, absolutely no overshoot, signal amplitude matched to clock
dqs7 measured on the dimm side of the termination resistor:
- dimm->cpu rank 0, DQS7 0.36 - 1.19V swing, 830mv total. seems over-driven compared to clock, some reflection seen. in-phase with clock.
- dimm->cpu rank 1 same effect
- cpu->dimm rank 0, DQ7 0.45 - 1.1V swing, 650mV total. a bit cleaner. negative overshoot down to 0.22v seen on leading edge. 180 degrees out of phase with respect to clock.
- cpu->dimm rank 1, same effect
DQS4 is seen as problematic in read/write tests, as evidenced by data patterns:
Novena U-Boot > tmw.l 0xa0000000 0x0000ffff 0x400 Novena U-Boot > tmd.b 0xa0000000 a0000000: ff ff 00 00 3f ff 00 00 ff ff 00 00 d0 ff 00 00 ....?........... a0000010: ff ff 00 00 ba ff 00 00 ff ff 00 00 f6 ff 00 00 ................
significantly, DQS4 is the very last DQS in the fly-by topology chain!
Handy Resources
Board layout files for SO-DIMMs. Looks like 90% of all SO-DIMMs use the reference design with very, very minor tweaks. There are basically two types of SO-DIMM layouts, one for single-rank, and one for dual-rank. The exception is Samsung, their low power DDR line has a novel layout. http://www.jedec.org/standards-documents/focus/memory-module-designs-dimms/DDR3/204-pin%20Unbuffered%20SODIMMs
