Hi Neeraj,

Thank you for the reply. I also want to know how to access SPI NOR flash in uboot. I followed this discussion, https://octavosystems.com/forums/topic/spi-nor-from-u-boot/. I have compiled “sf” commands and also added ““CONFIG_SPI_FLASH_SPANSION=y”” in config in the uboot. When I executed “sf probe 0”, it shows the error , “Invalid bus 0 (err=-19)

Failed to initialize SPI flash at 0:0 (error -19)”

I tried both am335x_evm_defconfig and am335x_evm_spiboot_defconfig, but both gave me the same error. Can you let me know how to modify to access it from uboot? THank you
