Troubleshootings and Errata corrige

This problem is due to the Vodafone Station that automatically redirects any requests on port 80 icoming from new MAC addresses.

To solve this problem open a browser on a PC wired on the same LAN and go to the following URL changing ff:ff:ff:ff:ff:ff with the MAC address of your Acme board:

http://vodafone.station/main.cgi?host_mac=ff:ff:ff:ff:ff:ff&force=1&page=setup_wizard.html#state=Customer.Type

Then click on the top-right X to close the page and confirm on the next page.

Now try again with apt-get command on your Acme board.

Solution

In /etc/network/interfaces change the line:

auto eth0

in:

auto eth0
allow-hotplug eth0

Then test the configuration by typing:

ifdown eth0
ifup eth0

Problem description

Memory swap command causes this error:

debarm:/etc# swapon /dev/mmcblk0p4                                              
swapon: /dev/mmcblk0p4: swapon failed: Function not implemented                 

Solution

The Linux Kernel is not configured to support the memory swap.

Follow this article:

• Compiling Linux Kernel 2.6.39 for the Aria G25 SoM

and enable the memory swap in:

General setup  --->
    [*] Support for paging of anonymous memory (swap)    

Enable the swap partition on the microSD adding these lines in /etc/fstab

#Enable the swap memory
/dev/mmcblk0p4 none swap sw 0 0

Create a Linux swap partition on microSD

The reason of is problem is well explained on this post and it can be caused intentionally typing

# hwclock -w

and removing the power supply before the command ends. The problem occours only if the RTC backup battery is present.

To solve it you have to replace the AriaBoot executable file (boot.bin) on the first partition if the bootable microSD card with one of these files:

• Aria Boot 0.26 for Aria G25 with 128MByte of RAM
• Aria Boot 0.26 for Aria G25 with 256MByte of RAM

Renaming one of it in boot.bin.

The changes on AriaBoot source file are available on GitHub.

We found an insidious DDR2 RAM memory problem on the AriaG25-256. If your board already has the patch wire shown below the problem was already solved by us before shipment.

If your board has not the patch wire it could be affected by a memory fault problem highlighted only using the memtester utility.

According to our test this issue does not affect the AriaG25-128 boards (How to recognize an Aria G25 with 128MB or 256MB).

To highlight the problem install memtester on your AriaG25-256:

# apt-get install memtester

Then lauch:

# memtester 1M

If your board fails one or more benchmarks you need to place the patch wire to avoid them. The two points to wire are the follow:

On the next production batch planned for october we'll eliminate this patch wire fixing the PCB.

Those who ordered the Aria G25 during the first and are using a Debian microSD from Acme the serial ports ttyS1,S2,S3,S4 and the I2C and 1-Wire can't enabled due a wrong kernel configuration .

The solution is to use the R4 version available on Bootable microSD card binaries repository. It is enough to change just the uImage file on the first partition of the bootable SD card.

Problem description

Sometime after a reboot command the FOX Board G20 hangs.

Solution

If you are using a self compiled kernel 2.6.38 uImage comment these two lines on arch/arm/mach-at91/at91sam9_alt_reset.S: and make again a uImage:

//str   r2, [r0, #AT91_SDRAMC_TR]       @ disable SDRAM access
//str   r3, [r0, #AT91_SDRAMC_LPR]      @ power down SDRAM

If you are using an Acme factory default uImage download this uImage file:

• uImage_reboot (MD5: 0f2ea8f58cb35bef889058077751a27f)

Rename it in uImage and copy it on the first microSD FAT32 partition called "kernel".

You can change it remotely copying the uImage in the directory /media/mmc_p1:

$ scp uImage_reboot root@[fox IP number]:/media/mmc_p1/uImage

and rebooting the FOX.

This problem is due to a wrong production batch of ethernet connectors where the yellow led is inverted. Unfortunately is not so simple to change this connector so we could suggest to mount an external led as shown in the figure below.

Edit the file /etc/cron.weekly/apt-xapian-index end insert "exit 0" after the first line:

#!/bin/sh
exit 0

Probably your FOX Board G20 mount an AcmeBoot loader version 1.19 or older. Move to the new a version 1.20 or higher (Go to AcmeBoot page).

This is due to a bug on the atmel-mci.c Kernel 2.6.32.2 driver up to September 2010. Use the the latest kernel image available on binary snapshot to avoid this problem.

If you are still using the U-boot bootloader instead of AcmeBoot with a Debian microSD higher than R03 add foxg20-script.bin on the first FAT partition of your bootable microSD or move from U-boot to AcmeBoot.
