Re: [U-Boot] at91sam9260ek and mmc
Dear Reinhard, during last week I have been trying to make sd card in u-boot working on at91sam9260ek, unfortunately without success. I have posted some details in this post on the mailing list http://lists.denx.de/pipermail/u-boot/2011-June/093666.html I'm almost sure that it is not a hardware issue, because in Linux booted from nand flash sd works like a charm, even mounting rootfs on the sd is possible. You stated, that you have sd card working in your development branch, could you share it, please? It seems I'm not able to fix it by myself :( with best regards Jan Dne Mon, 30 May 2011 21:07:37 +0200 Reinhard Meyer napsal(a): > Dear Jan Pohanka, > >> I'm trying to get u-boot 2010.12 working on at91sam9260ek devkit with >> mmc support.

[U-Boot] gen-atmel-mci driver bug?
Hello, I'm playing with mmc/sd card on a custom board with at91sam9g20 processor. U-boot v2011.3 now runs well as I added support for AT45DB041 dataflash, which is used on my board. It's size is only 512kB so I need sd card for Linux image and rootfs. Unfortunately I still can't get mmc/sd suport working. I have a micro sd (not hc) card connected to a MCI interface port A.

Yes, my custom board is based on sam9g20 chip, but I tried u-boot on 9260ek first, because it was the only development board available for me and supported by u-boot. Now I have u-boot running on my board with mmc on port b, but it does not work yet, maybe I will success today... regards Jan > > -joey > > On 5/30/2011 4:34 AM, Jan Pohanka wrote: >> >> Hello, >> I'm trying to get u-boot 2010.12 working on at91sam9260ek devkit with >> mmc support.

[U-Boot] at91sam9260ek and mmc
Hello,
I'm trying to get u-boot 2010.12 working on at91sam9260ek devkit with
mmc support. I have read several discussions here and followed the
steps described in README.atmel-mci. (my config and board file are
below...)
There are two issues I'm facing.
The first one: When I enable mmc support, the dataflash stops to work.
According to info from boot process, dataflash is detected correctly,
but no data can be read (environment) or written.
RAM Configuration:
Bank #0: 2000 64 MiB
NAND: 256 MiB
DataFlash:AT45DB642

Area 3: D0042000 to D0251FFF Kernel
Area 4: D0252000 to D083 FS
MMC: mci: 0
*** Warning - bad CRC, using default environment
The second one: fatls command causes u-boot to freeze with following message

I'm a newbie with u-boot, could please someone give me any hints where
to start to make this working?
