$this->bbcode_second_pass_quote('Admin', 'O')r just do number 2 and get a powered USB hub. :mrgreen:


ofc the usb hub is powered!

I tried two different powered hubs, but it's not a power issue. It doesn't matter whether i have the bootusb + webcam or bootusb + webcam + 8 other devices, its because of the webcam...

$this->bbcode_second_pass_quote('peaslaker', '')$this->bbcode_second_pass_quote('netter', 's')o no one has any solutions, or hacks to get past these boot problems?

3. (the sidestep bodge) install the kernel to NAND and boot from NAND with a good long pause before expecting to find anything sensible on USB storage. Leave the USB system to settle out and the system will never know the difference, although if you smell smoke you should probably switch it off.


hell i'd even take a solution that boots from nand -> usbboot, but ofc starts running from the usbboot fully, and drops nand later.

$this->bbcode_second_pass_quote('Samson', 'I') believe you have to get access to uBoot environment....


if your talking about printenv, then no, I just get some info about the bash shell settings. Maybe I'm doing it wrong?

edit:
$this->bbcode_second_pass_quote('', '/')etc/fw_env.config
# Configuration file for fw_(printenv/saveenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# Notice, that the "Number of sectors" is ignored on NOR.

# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000


this file is missing for me, so what are the correct offsets for a tonido plug?

edit2:
from the beginning of this link:http://Arch Linux ARM.com/forum/viewtopic.php?f=25&t=413 using cat /proc/mtd

I was able to get these numbers:
mtd0 00100000 00020000 "u-boot"
mtd1 00400000 00020000 "uImage"
mtd2 1fb00000 0020000 "root"

How can I can convert these to a fw_env.config file?

edit3:

no idea why but this works
