Hacking With AriettaG25

"Tiny, cheap and easy ARM9@400Mhz Linux Embedded module for DIY and Maker cultures " http://www.acmesystems.it/arietta

Everything worked as described. Nice and smoothly. I will write down my raw notes about my customisations here and maybe someone finds these helpful.

Porting OpenBSD to AriettaG25

Once again I don't have any idea how to do it, but I will try and learn...

Building at91bootstrap with u-boot

~/at91bootstrap$ make arietta-256m_defconfig
Select:
Image Loading Strategy (Load U-Boot into last MBYTE of SDRAM)
Exit and save

~/at91bootstrap$ make CROSS_COMPILE=arm-linux-gnueabi-

Now there should be second level bootloader for Arietta. You can find it from binaries/at91sam9x5_arietta-sdcardboot-uboot-3.7.bin. It tries to load actual u-boot.bin from the SD-card (I guess) so we need to get working u-boot binary.
