Description

This Answer Record acts as the release notes for PetaLinux 2018.2 and contains links to information about resolved issues and updated collateral contained in this release.

Solution

BSPs supported for the 2018.2 PetaLinux Release

This table contains supported BSPs for Zynq-7000, MicroBlaze, Zynq UltraScale+ MPSoC available on the Embedded Development download page.

Note: The “sstate cache file” (sstate-rel-v2018.2.tar.gz) can be found on the Xilinx download area along with an associated README (sstate_rel_2018.2_README) file that outlines the procedure to use “sstate cache”.

Refer to the attached file “2018.2_PetaLinux_Packages_List” for software package versions tested on host machines, which is required for PetaLinux installation tools.

2018.2 New Features:

PetaLinux

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

Yocto

• None

FSBL

• None

U-boot

• 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

QEMU

• None

VCU

• 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.

XEN

• None

FreeRTOS

• 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:

  • 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 overwritten 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
