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:
| BSP Release Version | BSP Release Date | SOM PCB Version | FLEX Mapper Board Version | FLEX Baseboard Version |
|---|---|---|---|---|
| PD14.1.0_EA1 | July 14th, 2014 | 1362.2 | 1367.3 | 1364.4 |
| 1362.1 | 1367.2 [A] | 1364.3 [B] | ||
| 1367.1 [B] | 1364.2 [A] |
[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).

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.

Fixed in this Release
N/A
New in this Release
- Yocto build environment
- linux-imx kernel version 3.10.17 support
- device tree 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.
- WLAN: does not operate in multirole mode
- CAN: will not work correct with 1 Mbit/s
- [2] Audio: Hset_OUT makes problems with some MONO audio files
- [3] USBH: Disabled by default, host mode reset triggering.
- [4] ETH0: If eth0 is brought down with ifconfig while another network interface is up other than lo, and then a network operation is attempted (ping, dhclient, ifup on wlan0, etc), an Oops happens because the kernel has underrun the number of free pages due to the teardown buffers. Doesn't occur with wlan-disabled build. This issue has been verified with different Network Mangers (on both debian-jessie and fsl-image-fb root filesystems).
Workaround: Do not bring eth0 down while another interface is up (ex. wlan0).
- 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.
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).
