2018.2 New Features:


  • PetaLinux BSPs for Ultra96 (Rev 1.0) and ZCU111 production boards.


  • None


  • None


  • Added support for QPSI I/O mode for Zynq UltraScale+ devices.
  • Fixed saveenv to SPI flash issue on AC701.
  • Added support to setup MMU map based on memory node entries in device-tree for Zynq UltraScale+ devices.
  • Added support to load bitstreams using zynqrsa command for Zynq devices.
  • Fixed issue with Macronix QSPI flash devices in dual parallel mode.
  • Add support for Macronix devices mx25u12835f and mx25u25635f.
  • Enhanced Key Revocation XILSECURE for Zynq UltraScale+ devices.
Device-tree Generator (DTG)
  • Add support for USB 2.0 for Zynq UltraScale+ devices.

ARM-Trusted Firmware (ATF)

  • Add Zynq UltraScale+ MPSoC firmware IOCTL to set healthy bit.
  • Fixed deprecated warnings.

PMU Firmware (PMUFW)

  • Change healthy bit from GGS0[29] to GGS4[0]
  • Provide read and write access to AFI configuration registers
  • Enable PLL lock errors only after FSBL completes psu_init to avoid initial
  • PLL lock errors that occur during psu_init
  • Increased polling period of DDR status register to 1ms which is used during
  • DDR re-initialization since 100us is not enough for some DDR memories
  • Fix proc assignment in PmProcGetByWakeMask by returning proc pointer instead of node structure pointer
  • If POS is enabled, signal the FSBL with boot type in APU only restart to avoid infinite wait loop in FSBL
  • Use proper function(PmSlaveChangeState) when resetting the slave state
  • Power Management
  • Fixed APU only reset when Power Off Suspend is enabled
  • Fixed reboot fail after powering down PLD issue
  • Fixed compilation warning in xilpm build
  • Updated SDK DDR self refresh example to use PMU APIs

Linux Kernel and Drivers

  • Firmware driver
    • Add ZynqMP firmware sysfs and IOCTL to set healthy bit
  • Display Port
    • Override the preferred format for fbdev. This allows the fbdev to be initialized with AR24
    • Update DRM planes asynchronously. Otherwise, framerate is time-shared when CRTC and plane are running.
  • AXI DMA Driver
    • Add 64MB data transfer support.
  • FPGA Manager
    • Add support for PL bitstream partial reconfiguration. For more details refer to the ZynqMP PL Programming wiki page.
OpenAMP and Libmetal

  • None


  • None


  • Fixed AVC Decoder hang issue for corrupted input file
  • Fixed data corruption issue observed with b-frame enable
  • Fixed zynqmp_vcu_encode application to support b-frames in AVC.
  • Fixed long run frame drop issue for AVC1080p60 decode display with large input file
  • Fixed bad parameter error when setting baseline profile and level=5.1
  • Fixed MCU clock division calculation in VCU Init driver.
  • Improve CBR/VBR rate control for static video sequences.


  • None

  • Updated licensing information as per FreeRTOS 10.0

Power Management

  • None

Baremetal Drivers and Libraries

  • rfdc_v4_0:
    • Added XRFdc_MTS_Sysref_Config API to enable/disable sysref.
    • Updated max VCO value to 13108MHz to support max DAC sample rate of 6.554MHz.
    • Added macro to configure Threshold OFF mode.
    • Adjust calculated latency by sysref period, where doing so results in closer alignment to the target latency.
    • Corrected Set/Get MixerSettings API description for FineMixerScale parameter.
    • Enable VCO Auto selection while configuring the clock.
    • Added XRFdc_GetPLLConfig() API to get PLL Configurations.
    • Added XRFdc_GetLinkCoupling() API to get the Link Coupling mode.
    • Added clock configuration files for ZCU111 in examples.
  • standalone_v6_7:
    • Fixed compilation warnings in xil_sleeptimer.c
  • xilfpga_v4_1:
    • Added partial bitstream loading support.
  • xilsecure_v3_1:
    • Added support for 512, 576, 704, 768, 992, 1024, 1152, 1408, 1536,1984, 3072 key sizes, where previous version has support only 2048 and 4096 key sizes.
    • On GCM tag failure, wrongly decrypted data will be zeroized.
    • Added support of user fuses revocation for single partition image.
    • Modified xilsecure_aes_example,input data will be over written with decrypted data
    • Added compilation flag for opting secure/non-secure environment, by default it is non -secure, mainly it is taken into account while building PMUFW
  • xilskey_v6_5:
    • Fixed hanging issue for BBRAM Zynq UltraScale+ MPSoC when program/zeroize is requested while programming mode is in enabled state
