We are trying to boot T1040RDB from SPI, here is what i have tried so far


1) Build u-boot.(make T1040RDB_SPIFLASH_defconfig)


2) copy the generated u-boot.bin and u-boot-with-spl-pbl.bin


=>tftp 100000 u-boot-with-spl-pbl.bin

=>sf probe 0

=>sf erase 0 100000

=>sf write 100000 0 $filesize

write u-boot.bin at offset 0x40000 (256KB):

=>tftp 100000 u-boot.bin

=>sf write 100000 40000 $filesize


Change the switch setting as below


SW1 [1:8] = 0010 0010

SW2 [1:8] = 1011 1011

SW3 [1:8] = 1110 0001


So far i have been unsuccessful, my understanding is that u-boot will build PBL.bin with default rcw which is good enough to test boot from spi. Is my understanding correct? Am i missing something?
