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. 9*876a25d2SStefano Babic 10*876a25d2SStefano BabicMore information on the board can be found on manufacturer's 11*876a25d2SStefano Babicwebsite: 12*876a25d2SStefano Babic 13*876a25d2SStefano Babichttp://www.phytec.de/produkt/single-board-computer/phyboard-mira/ 14*876a25d2SStefano Babichttp://www.phytec.de/fileadmin/user_upload/images/content/1.Products/SOMs/phyCORE-i.MX6/L-808e_1.pdf 15*876a25d2SStefano Babic 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. 36
