SPI NOR BOOT in i.MX6 Solo based Custom board

[anjalikkrishna]

Hi,

   Facing an issue related to SPi boot. I flashed the u-boot binary using sf write command also used dd command to flash the binary to SPI.Both the cases after changing the boot switch mode to SPI boot mode, no prints are coming in the print console.

Flashing the binary using dd and sf command is successful.

When we tried probing Chipselect signal appears to go from high to low but no clock signals appears.

Any help would be appreciated.

Hi Anjalik

which reference board is based custom board. For example i.MX6Q Sabre SD has spi-nor

but it is not able to boot from it. Sabre AI reference board is able to boot from spi-nor.

Reason is spi-nor iomux configuration, described in Table 8-23. SPI IOMUX Pin Configuration
