Introduction

This BSP provides a basis for development, deployment and execution of Linux based applications on the phyFLEX-i.MX6 System on Module (SOM). For detailed information on the various software components included in the release and how to use them, please refer to the Quickstart.

Versioning

This Release is compatible with the following hardware:

[A] Does not fully support PCIe. FLEX Mapper board does not include nPCIe0_PERST. FLEX Baseboard missing 100Ω termination resistor on PCIe clock and reset for an extra PCIe.[B] Hardware interface does not support Camera0 interface extension and full 18-bit Camera0 (missing J6 and J7 for CSI0_DAT3 and CSI0_DAT2 signal multiplexing). Different reset out circuitry for Camera0 and Camera1. JP12 does not exist (X_CAMERA1_CLK & X_CAMERA0_CLK).

Note:

There are a wide variety of configurations (Quad/DualLite/Solo, RAM sizes, and WiFi) for the phyFLEX-i.MX6 SOM. Please note that there are different versions of software for each configuration.

Current support is available for the i.MX6 Quad with 1 GB, 1 bank of RAM. Additional configurations are targeted to be supported in the next BSP release.

• Audio ^[4]
• DVFS

Fixed in this Release

• ETH0: eth0 can be brought down with ifconfig while another network interface is up.
• USBH: enabled, and host mode reset no longer triggering.

New in this Release

• Sync with 3.14.14 with linux-fslc
• Integration of LCD-018-070-KAP - EDT ETM0700G0DH6 TTL / FocalTech FT5306 capacitive touch
• Migration to direct-fb framebuffer support

Known Issues

• ^[1] i.MX6 Quad is only tested with 1 GB RAM values
• Using Barebox to flash Barebox to NAND does not work
• Saving default environment to SD Card does not work, but forcing use of NOR on SDBoot is available.
• CAN: will not work correct with 1 Mbit/s
• ^[2] USBH: Requires devices to be plugged in on boot.
• ^[3] WiFi: SD3 SDIO lines for WiFi are shared with the SD interface that is used to boot the kernel and root filesystem. Therefore, you cannot boot from SD card and enable WiFi at the same time.

Workaround: Boot the kernel and root filesystem from network or the kernel and root filesystem from the SD2 interface.

• ^[4] Audio: Does not create a soundcard.
• UBIFS: The partition generation process isn't creating a root filesystem that barebox will recognize. Claims mismatch.

Workaround: Use NFS-based root filesystem or sd-card based root filesystem.Required Fix: The MKUBIFS_ARGS setting must be configured to match how barebox is reading the partition, or the partition scheme itself is offset incorrectly.

• LiveDVD runs Ubuntu 12.04 LTS which requires a security update for OpenSSL to protect against the heartbleed bug.

Upgrade and Compatibility Information

This BSP is not backwards compatible and has no workaround for 1362.0 SOM and 1364.1 Baseboard due to a change in PCB pinout, see Modification of the pinout for the phyFLEX-i.MX6 (PLF-A-XL1).

Dependencies
