U-Boot environment variables can be stored at different places:
- Dataflash on SPI chip select 0 (dataflash card)
- Nand flash.
- - Nor falsh (not populate by default)
+ - Nor flash (not populate by default)
You can choose your storage location at config step (here for at91sam9260ek) :
make at91sam9263ek_config - use data flash (spi cs0) (default)
make at91sam9263ek_nandflash_config - use nand flash
make at91sam9263ek_dataflash_cs0_config - use data flash (spi cs0)
- make at91sam9263ek_norflash_config - use nor falsh
+ make at91sam9263ek_norflash_config - use nor flash
You can choose to boot directly from U-Boot at config step
- make at91sam9263ek_norflash_boot_config - boot from nor falsh
+ make at91sam9263ek_norflash_boot_config - boot from nor flash
