Unable to boot from SPI-NOR on imx6q-sdb

[linhsun]

Dear all

   My board is imx6q-sdb broad, I setting boot mode to SPI mode, after weld a spi-flash chip (U14, R643, R646, R149 C83, can see figure 1),  last flash an u-boot.bin to NOR Flash (use mfgtool), but can not load bootloader from SPI(always into download mode), please get me several suggest(is something missing?), thank.

NOTE：I believe SPI NOR has code(use mfgtool flash u-boot to NOR is success), will be into bootloader

My config information:

 SBMR1 ---> 0x18000030 

 BOOT_CFG1[7:4] --> 0011

 BOOT_CFG4[5:4] --> 01 - ECSPIx_SS1

 BOOT_CFG4[3]    --> 1 - 3-bytes (24-bit)

 BOOT_CFG4[2:0] --> 000 - ECSPI-1
