External SD card on nokia n810.

External SD card on nokia n810.

[Maksim A. Boyko]

Hi,

I try to boot n810 using root on external SD card with few recent
linux-omap kernels. For example, with commit 151c7a7f it is ok, but
with recent kernels it does not. Can I use recent kernel with root on
external SD?

Thanks.

How recent? I was able to use uSD root on N810 about 1-2 weeks ago with
linux-omap head. The 2nd slot was broken between ~mid 2009 and Aug 2010.

Аpproximately 2-3 weeks ago. Is uSD internal mmc (/dev/mmcblk1) ?
How hard to fix 2nd slot?

2nd slot was fixed by the commit 214044b. I just tried and both internal
mmc and external microSD (=uSD) are working on current l-o head 8b4b015.

I used omap2plus_defconfig as a base. For cutting down the kernel size
for Nolo I disabled OMAP3 and OMAP4 support and enabled
CONFIG_KERNEL_LZMA=y.

Then I enabled all CONFIG_CBUS_RETU drivers and used ttyO2 as a
console instead of ttyS2 because serial port name got recently changed.

FYI: here is some info how to get access to N810 serial port pins.
Makes debugging much easier :-)
