Hi, we are using QorIQ T4240 processor, we used 2 pcs SPI flash to store rcw and uboot file, T4240 read rcw configurations and boot from SPI device. we design two spi flash, one is active device, another is backup device, when active device image was bad,we hope it can auto switch to backup device. now we erase one SPI flash all contents, another flash is ok, but CPU can't recover it from another flash, no any output from console port, the hreset signal always keep low. when T4240 can't get rcw and uboot successfully, the problem is reasonable?
