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

| Building U-Boot |
| ------------------------------- |
| |
| $ make pcm058_defconfig |
| $ make |
| |
| This generates the artifacts SPL and u-boot.img. |
| The SOM can boot from NAND or from SD-Card, having the SPI-NOR |
| as second option. |
| The dip switch "DIP-1" on the board let choose between |
| NAND and SD. |
| |
| DIP-1 set to off: Boot first from NAND, then try SPI |
| DIP-1 set to on: Boot first from SD, then try SPI |
| |
| The bootloader was tested with DIP-1 set to on. If a SD-card |
| is present, then the RBL tries to load SPL from the SD Card, if not, |
| RBL loads from SPI-NOR. The SPL tries then to load from the same |
| device where SPL was loaded (SD or SPI). Booting from NAND is |
| not supported. |
