Overo FE vs IronStorm

[hobbesc7]

Two questions regarding the IronStorm vs FE COM:

1.  Will my rootfs and kernel, that I currently use on the FE, work on the IronStorm?

2.  Will the IronStorm power consumption be significantly less than on the FE at low cpu frequencies?  I use the cpu freq "ondemand" governor, and generally my FE runs at 125 MHz.

[Steven]

1. Yes, depending you how old your FE is you might need to reconfigure
your bootloader to use a different serial port (i think /dev/ttyO2 vs
/dev/ttyS2)

2. Not certain, but I suspect it won't be significantly lower since at
low clock speed the SOC might not be dominating the power draw.

A bit off topic: After reading this I fell in love with "ondemand".
Unfortunately this love is tainted by the fact that I can not restart
the system. Neither shutdown -r nor pressing reset work for OveroWater
and OveroFireStorm. U-boot hangs before or during uncompressing
kernel. I tries different kernel versions / and latest u-boot
(2012.07). The only way out is unplugging power.
Anybody else facing this?

It turns out the answer to #1 is no.  I'm testing two new Ironstorms with the same MLO, u-boot, kernel, and rootfs that I use on the FEs.  (Flashed to NAND.)

I booted up both ironstorms with my usual SD card that has my images for flashing to NAND.  After removing the SD card and rebooting from NAND, however, both ironstorms have kernel crashes in the form of "Unable to handle kernel paging request at virtual address."

Here's the boot output up until it hangs:

Should the way I make a ubi image and flash it to the NAND change at all for the IronStorm from the FE?

I'm following the instructions in Method 2 at

http://www.sakoman.com/OMAP/how-to-write-an-ubifs-rootfs-image-to-nand.html?utm_source%3Dfeedburner%26utm_medium%3Dtwitter%26utm_campaign%3DFeed:+BeagleBoard+%28BeagleBoard.org%29

to make the ubi image, and then the instructions at

http://www.gumstix.org/how-to/70-writing-images-to-flash.html

to write to the flash.

As I say, this all works fine on the FE, but the IronStorm hangs at  "Freeing init memory: 332K".

[hobbesc7]

The Gumstix product info page for the IronSTORM COM claims that "According to Texas Instruments, DM3730 is fully backward compatible with previous OMAP™ processors."

It appears this isn't the case -- I am not able to use my same kernel (based on Sakoman's 3.2) and filesystem on the IronSTORM as I used on the Fire/FE.

[hobbesc7]

So I got my Ironstorm to boot by switching from Sakoman's omap-3.2 branch to omap-3.5.  I'm using the same firmware files as used to work for me on the Overo Fire/FE, with omap-3.2.

But now wifi won't come up.

[hobbesc7]

On boot I never see "mmc1: new SDIO card at address 0001."  I do see this message when booting 3.0 from an SD card (I'm booting 3.5 from NAND.)

I can tell the wifi hardware isn't really turning on, because the Gumstix isn't scorching hot like it is when things are running "normally," lol.
