| 2 | ----------------- |
| 3 | |
| 4 | The SBC produced by Phytec has a SOM based on a i.MX6Q. |
| 5 | The SOM is sold in two versions, with eMMC or with NAND. Support |
| 6 | here is for the SOM with NAND. |
| 7 | The evaluation board "phyBoard-Mira" is thought to be used |
| 8 | together with the SOM. |
| 9 | |
| 10 | More information on the board can be found on manufacturer's |
| 11 | website: |

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