I am facing issue in SPI boot on i.MX6Q based Solo board. When I boot image from SD card and flash the u-boot binary to SPI flash , write is successful and able to read and erase the SPI NOR memory. But Uboot is not coming up once I change the boot media to SPI.
Below are the lines which I have used for SPI
EIM_D17 - MISO.alt1
EIM_D18 - MOSI.alt1
CSI0_DAT4 - CLOCK.alt2
EIM_EB2 - Chip Select
When we probed, the CS signal is appearing but no clock signals are coming. But the clock signals are being generated during read and write operations except during boot.
Can we use CSI0_DAT4 for clock instead of EIM_D16.alt1? Is EIM_D16.alt1 is mandatory for SPI NOR Boot?
