Dear Evgeniy, I looked the file "at91sam9263ek.h", and the dataflash address to set in SAM-BA seem to be 0x8000. In fact, if I use the same at91bootloader with uboot with this address, uboot starts correctly. If I use patched redboot for at91sam9263ek, redboot doesn't start and I only see "RomBoot>" shell. I used exactly your patch, apply on ecos-cvs, and the only thing I do, is to set RAM as default value of CYG_HAL_STARTUP in packages/hal/arm/at91/at91sam9/current/cdl/hal_arm_at91sam9.cdl. I downloaded redboot on my board with SAM-BA using DataFlash section with 0x8000 destination address. I don't understand why redboot doesn't start on my board.
