1 U-Boot for the Freescale i.MX6q SabreLite board
3 This file contains information for the port of U-Boot to the Freescale
7 ---------------------------------
9 The recent mainline U-Boot for the Freescale i.MX6q SabreLite board supports
12 a small SD card loader to support boot from SD card. This small SD card loader
14 the loader will in turn request the BootROM to load the U-Boot from SD card.
16 The SD card loader is available from
20 under a open-source 3-clause BSD license.
22 To update the SPI-NOR on the SabreLite board without the Freescale
25 1. Write this SD card loader onto a large SD card using:
31 Note: This writes SD card loader at address 0
37 3. Power-up the SabreLite, press 'space' to enter command mode in the U-Boot
41  MX6Q SABRELITE U-Boot > mmc dev 0
42  MX6Q SABRELITE U-Boot > mmc read 0x10800000 0 200
43  MX6Q SABRELITE U-Boot > sf probe
44  MX6Q SABRELITE U-Boot > sf erase 0 0x40000
45  MX6Q SABRELITE U-Boot > sf write 0x10800000 0 0x40000
50 the Freescale manufacturing tool in order to reflash the SPI-NOR.
