Hello, JohnnyOpcode:

We have not yet finished the porting task of all TechNexion products on u-boot 2017.10.
The existing deconfig file for pico-imx6ul is done by NXP for android things.

Moreover, there are two different types of PICO-IMX6UL SOM with 256MB and 512MB DRAM.
The u-boot done by NXP doesn't support SPL (secondary program loader).
So it'd be required to select the corresponding DCD table for different DRAM size of PICO-IMX6UL SOM.
SPL detects the DRAM size and have two different kinds of DRAM initialization in TechNexion u-boot.
It guarantees the same u-boot binary works on varieties of PICO-IMX6UL SOMs.

Could you use TechNexion u-boot 2016.03 in this stage?

I am sorry for the inconvenience to you.
I promise we'll make it ASAP.

BR,

Richard

[JohnnyOpcode]

Okay. I will work with 2016.03 for now and watch as 2017.x evolves. Thank-you for the update.

@richard-hu hi, i'm booting a pico-imx6ul using the last version of u-boot, everything is fine, but i need to patch DCD definition to match 512mb memory size, can you provvide the DCD constant changes?
thanks you in advance

Hello, SleepyDeb:

We change to initialize DDR in SPL for a long time.
In order to be compatible with both 256/512MB DDR, and i'd suggest to use SPL u-boot.
The attachment is the DCD table for 512MB that i extract from old commit on git and apply the updated DQS read/write calibration parameters from SPL.
imximage_512MB.zip

It should work well. :)

BR,

Richard

[SleepyDeb]

it works fine thanks!
