[1] Interface requires additional configuration, such as pinmuxing. It may be possible to change the software configuration to utilize this interface even if it is not being set in the board's default configuration. Please see NXP's i.MX7D Technical Reference Manual for more information on the various modes each pin can be muxed to.

Known Issues

PHYTEC Known Issues

Fails to restart in Linux and U-boot (using "reboot" or "reset" commands).
Flashing BSP to eMMC via U-boot currently not tested. Workaround: flash via Linux (See 45646010 for instructions)
DDR RAM timings not verified
If using carrier board PCB version 1459.0:
- LCD data signals at Audio/Video connector X3 are not in the order expected by PEB-AV-02, so colors are displayed incorrectly. Workaround: Use AV adapter PEB-AV-05-TC which was designed to be compatible with the 1459.0 PCB revision of the carrier board.
Ethernet RGMII2: ethernet performance issues
- Fix: The PHY RGMII timing delays need to be adjusted. See here for instructions and kernel patches.
