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.
