1*876a25d2SStefano BabicBoard information
2*876a25d2SStefano Babic-----------------
3*876a25d2SStefano Babic
4*876a25d2SStefano BabicThe SBC produced by Phytec has a SOM based on a i.MX6Q.
5*876a25d2SStefano BabicThe SOM is sold in two versions, with eMMC or with NAND. Support
6*876a25d2SStefano Babichere is for the SOM with NAND.
7*876a25d2SStefano BabicThe evaluation board "phyBoard-Mira" is thought to be used
8*876a25d2SStefano Babictogether with the SOM.

16*876a25d2SStefano BabicBuilding U-Boot
17*876a25d2SStefano Babic-------------------------------
18*876a25d2SStefano Babic
19*876a25d2SStefano Babic$ make pcm058_defconfig
20*876a25d2SStefano Babic$ make
21*876a25d2SStefano Babic
22*876a25d2SStefano BabicThis generates the artifacts SPL and u-boot.img.
23*876a25d2SStefano BabicThe SOM can boot from NAND or from SD-Card, having the SPI-NOR
24*876a25d2SStefano Babicas second option.
25*876a25d2SStefano BabicThe dip switch "DIP-1" on the board let choose between
26*876a25d2SStefano BabicNAND and SD.
27*876a25d2SStefano Babic
28*876a25d2SStefano BabicDIP-1 set to off:	Boot first from NAND, then try SPI
29*876a25d2SStefano BabicDIP-1 set to on:	Boot first from SD, then try SPI
30*876a25d2SStefano Babic
31*876a25d2SStefano BabicThe bootloader was tested with DIP-1 set to on. If a SD-card
32*876a25d2SStefano Babicis present, then the RBL tries to load SPL from the SD Card, if not,
33*876a25d2SStefano BabicRBL loads from SPI-NOR. The SPL tries then to load from the same
34*876a25d2SStefano Babicdevice where SPL was loaded (SD or SPI). Booting from NAND is
35*876a25d2SStefano Babicnot supported.
