[WarheadsSE]

Is this with the u-boot from Silverstone, or the one we have on github?

[hippo]

use DC01 u-boot souce.

below use GitHub souce:

so seems u-boot source code something wrong?

[WarheadsSE]

Try the 256M uboot you compiled, but interrupt it and run the printenv command. I'd like to see just that output.

same situation, kernel halt.

[WarheadsSE]

Definitively odd.

[hippo]

maybe AKiTiO use new U-Boot code to enable 256MB? or 256MB just for NAND, not for SATA?

[telzey]

There's a specific warning in the CPU documentation in the DC01 open source package.

Apparently if 256MB DDR is implemented using 2x1Gbx16 chips instead of 2x1Gbx8 chips then special software is "required" (presumably in the stage1 boot loader, but possibly in u-boot).

There is also mention on the DC01 webpage that ...
"This source code differs from the final version that is used on the retailing DC01."

I don't know the part numbers used in your AKiTiO so I can't check if they're x16 or x8.

The 128MB that we've got on the pogoplug is 1x1Gbx16 and so is the 128MB in the Medion Life.

AFAIK, the stage1 loader in the boot-from-sata thread here is built using the regular code, and so possibly doesn't know how to initialize the 256MB in the AKiTiO correctly.

The 256MB that is in the Iomega HMNDCE is 2x1Gbx16, and so it's HDD stage1 code might work for you if you can find a copy. Unfortunately the Iomega runs at 600MHz so using their stage1 would slow down your system, but it might let you know that that is where your problem lies.

[hippo]

AKiTiO MyCloud Mini use Hynix HY5PS1G831CFP-S6, x2.
in NAS 7825 Data Sheet page 16 say: two ranks of 1Gbx16 requires modified software. HY5PS1G831CFP-S6 is 1Gbx8? does not require special software? i hope so.

i also tried Iomega HMCE source. EMCLifeline-GPL-Bellagio.zip not include U-Boot source; EMCLifeline-GPL-Bellagio-patch.zip include U-Boot source for PLX, but not find Stage1 source. so i use DC01 Stage1 + HMCE U-Boot to test 256MB.

maybe i need compare U-Boot source between DC01 and HMCE, and patch DC01 U-Boot source for test 256MB.

Congratulations on your perseverance!

Your Hynix DDR chips are definitely 128MBx8 instead of 64MBx16 which is different to the Iomega which is the only other 256MB configuration that I know about.

Unfortunately, I don't know what that means in practice

Good luck with your continued exploration!
