I want to set imx6q-sdb board boot from spi flash, and I weld a chip (25P32) on U14of  imx6q-sdb board. 

And I can use sf command to detect/erase/write the Norflash successfully.

=> tftp bootrom.bin

Using FEC device

TFTP from server 192.168.1.101; our IP address is 192.168.1.10

Filename 'bootrom.bin'.

Load address: 0x12000000

Loading: #############################

         468.8 KiB/s

done

Bytes transferred = 419852 (6680c hex)

=> sf probe

SF: Detected M25P32 with page size 256 Bytes, erase size 64 KiB, total 4 MiB

=> sf erase 0 50000

SF: 327680 bytes @ 0x0 Erased: OK

=> sf write 12000000 0 6680c

SF: 419852 bytes @ 0x0 Written: OK

 

 

And I turn on the DIP 5, and DIP 6 of SW6.

But now CPU can not boot from SPI-flash.

 

 

And the bootloader I used can work on SD card successfully.

 

Thank you.
