1*4882a593SmuzhiyunBoard information 2*4882a593Smuzhiyun----------------- 3*4882a593Smuzhiyun 4*4882a593SmuzhiyunThe SBC produced by Phytec has a SOM based on a i.MX6Q. 5*4882a593SmuzhiyunThe SOM is sold in two versions, with eMMC or with NAND. Support 6*4882a593Smuzhiyunhere is for the SOM with NAND. 7*4882a593SmuzhiyunThe evaluation board "phyBoard-Mira" is thought to be used 8*4882a593Smuzhiyuntogether with the SOM. 9*4882a593Smuzhiyun 10*4882a593SmuzhiyunMore information on the board can be found on manufacturer's 11*4882a593Smuzhiyunwebsite: 12*4882a593Smuzhiyun 13*4882a593Smuzhiyunhttp://www.phytec.de/produkt/single-board-computer/phyboard-mira/ 14*4882a593Smuzhiyunhttp://www.phytec.de/fileadmin/user_upload/images/content/1.Products/SOMs/phyCORE-i.MX6/L-808e_1.pdf 15*4882a593Smuzhiyun 16*4882a593SmuzhiyunBuilding U-Boot 17*4882a593Smuzhiyun------------------------------- 18*4882a593Smuzhiyun 19*4882a593Smuzhiyun$ make pcm058_defconfig 20*4882a593Smuzhiyun$ make 21*4882a593Smuzhiyun 22*4882a593SmuzhiyunThis generates the artifacts SPL and u-boot.img. 23*4882a593SmuzhiyunThe SOM can boot from NAND or from SD-Card, having the SPI-NOR 24*4882a593Smuzhiyunas second option. 25*4882a593SmuzhiyunThe dip switch "DIP-1" on the board let choose between 26*4882a593SmuzhiyunNAND and SD. 27*4882a593Smuzhiyun 28*4882a593SmuzhiyunDIP-1 set to off: Boot first from NAND, then try SPI 29*4882a593SmuzhiyunDIP-1 set to on: Boot first from SD, then try SPI 30*4882a593Smuzhiyun 31*4882a593SmuzhiyunThe bootloader was tested with DIP-1 set to on. If a SD-card 32*4882a593Smuzhiyunis present, then the RBL tries to load SPL from the SD Card, if not, 33*4882a593SmuzhiyunRBL loads from SPI-NOR. The SPL tries then to load from the same 34*4882a593Smuzhiyundevice where SPL was loaded (SD or SPI). Booting from NAND is 35*4882a593Smuzhiyunnot supported. 36
