FOX Board G20 technical documentation Buy
Sometime after a reboot command the FOX Board G20 hangs.
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:
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.
When used a Debian microSD Acme R14: The FOX hangs after some days of regular work
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
On the FOX board G20 the rootfs goes up in read-only mode
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.
On the FOX board G20 u-boot can't find foxg20-script.bin
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.
