Quickstart

Quickstarts for Yocto i.MX6: BSP Yocto i.MX6 Manual PD16.1.x

Fixed In This Release

• Kernel

  • CAN is now working with 10 kbaud

  • A bug was fixed where the LVDS display sometimes did not show anything after boot. This bug is described in erratum ERR009219

  • Fixed a typo in the HDMI devicetree node which prevented DDC to work correctly.

  • The npwrdn GPIO assignement on the phytec-mediabus was fixed from GPIO5_27 to GPIO3_9 on the phyBOARD-Mira.

  • Fixed a bug described by erratum ERR007117 which led to an infrequent detection failure of the NAND flash during boot.

  • Fixed a GPU stability issue where the GPU clocks run on clock rates which were to high by default.

  • Fixed a stability issue when switching the internal LDOs of the i.MX 6DualLight into bypass mode.

  • Introduced small performance improvements by disabling spinlock debug logging which is enabled by default.

  
  

• Barebox

  • Barebox devicetree now supports environment on SPI-NOR flash

  • Fixed the CS0_END RAM setting for the i.MX 6QuadPlus

  • Fixed a bug described by erratum ERR007117 which led to an infrequent detection failure of the NAND flash during boot.

  • Improved RAM timings for i.MX6 DualLite\Solo (400 MHz) on all phyFLEX machines.
