v1.0.7 Release Notes​

Release Date: 2026-08-26

Major Updates​

  • Added support for RISC-V64 hardware cryptographic acceleration
  • Added support for reading K3 chip ID
  • Fixed PCIe link training failure during wake-up recovery

  • Fixed USB hub port reset recovery delay (added TRSTRCY)
  • Optimized K3 OPP table to use efuse calibration values for thermal temperature reference

v1.0.5 Release Notes​

Release Date: 2026-07-23

Major Updates​

  • Fixed the NVMe timeout issue.
  • Fixed the black screen and unavailable mouse and keyboard after resuming from suspend.
  • Fixed the issue where TX delay did not take effect during SD/SDIO TX tuning.
  • Fixed the load access fault issue when remoteproc obtains get_loaded_rsc_table.
  • Fixed an issue where abnormal VPU messages could cause the decoder to hang.
  • Fixed the cluster power-off failure when the rvtrace clock is enabled by default.
  • Added support for PXE booting through the second boot device specified by TLV.
  • Added support for RVA23 extension feature descriptions in DTS.
  • Added support for using the SoC RTC as the clock source for RT-Linux.
  • Optimized asynchronous PCIe resume to reduce resume time.
  • Optimized the suspend flow by switching to a hardware-aware external interrupt mechanism.
  • Optimized the I2C, GMAC, QSPI, and eSPI pinctrl drive strength on the PICO board.
  • Optimized cpuidle to power off cluster3 synchronously when enabled.
  • Optimized perf rvtrace by using an ELF-based method instead of /dev/mem access.
