Hi Peng
With some wild guessing I found out that it must be an interrupt
issue. If I clear FR (offset 0x160) in the QSPI module using u-boot

the interrupt flag of the QSPI module after it was used.

Hi
I work with an imx6sx sdb. I observed that placing u-boot in QSPI
flash and also having the environment in QSPI the linux kernel doesn't

u-boot resides in QSPI and the environment is on mmc then the kernel
boots successfully
