imx6q u-boot NAND support

Hi!

Having a custom board with IMX6Q I'm trying to bring up NAND сhip (MT29F2G08ABAEA).

I've already compiled a few u-boot versions from different vendors and repositories including Freescale, Boundary and Denx mainline. I have to mention that in all repositories I use nitrogen6x board as reference because it has similar design and very convenient set of files to fill in DDR3 registers. I need to modify DDR settings because DDR3 calibration tools shows different values.

So what I achieved so far:

1) Freescale uboot-imx->imx_v2013.04_3.10.17_1.0.0_ga

boots fine, NAND detected, NAND erase hangs:

U-Boot 2013.04-04989-g6bb0820-dirty (Apr 06 2016 - 09:46:52)

CPU: Freescale i.MX6Q rev1.5 at 792 MHz

CPU: Temperature 37 C, calibration data: 0x5824ec69

Reset cause: POR

Board: Nitrogen6X

I2C: ready

DRAM: 1 GiB

NAND: 256 MiB

MMC: FSL_SDHC: 0, FSL_SDHC: 1

MMC: no card present

MMC init failed

unsupported panel HDMI

Page size 2048 b

OOB size 64 b

Erase size 131072 b

U-Boot > nand erase.chip

NAND erase.chip: device 0 whole chip

<<<here nothing happens and the board hangs

2) Denx u-boot mainline, branch v2016.03

git clone https://github.com/u-boot/u-boot

cd u-boot/

git checkout v2016.03 -b tmp

Results: boots fine, NAND detected, NAND erase hangs with lots of DMA errors:

Please check the attached patch of my changes to 2016 u-boot. It is based on this patch http://lists.denx.de/pipermail/u-boot/2014-November/194898.html

Somebody please help me to enable NAND support in u-boot!

Hi Maxim

please look at

Hi Igor!

That really helped!

Just to keep it for other users:

git clone https://github.com/u-boot/u-boot

cd u-boot

git checkout v2013.10

make ARCH=arm titanium_config

make ARCH=arm CROSS_COMPILE=/opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin/arm-linux-gnueabihf- -j4
