Release Notes

GSRD

  • Arrow SoCKitGSRD has been updated to ACDS14.0 code base using ACDS14.0 tools and software release.
  • Arrow SoCKitGHRD is upgraded to support rev B and C boards and the new QSPI flash component
  • DTC is no longer released as part of SoCEDS. User can generate the DTB from sopcinfo using sopc2dts.

Note: Do not use the GHRD that is part of SoC EDS with the GSRD. Always use the GHRD that is delivered as part of GSRD.

Linux

This Linux BSP release supports the Arrow SoCKit, and provides the following for the CycloneV SoC:
  • Linux kernel v3.13
  • Drivers: I2C, LCD, EEPROM, RTC, Ethernet, USB (Host), Watchdog, SD/MMC, QSPI, DMA, FPGA Manager, and FPGA Bridges
  • Boards: Arrow SoCKit (Rev B, Rev C and later).
  • U-Boot 2013.01
  • Linaro's GCC 4.7 2012.11

Known Issues

Issue Headline Description
99507 i2c speed is slow Running @50KHz instead of 100KHz because onboard LCD does not support 100KHz
103050 Transmit offloading on receive side doesn't produce a speed improvement Ethernet checksum calculation is not correctly offloaded from CPU to hardware
112140 stmmac_tx_timeout() is very broken the linux ethernet driver The function stmmac_tx_timeout needs to be updated to properly follow the datasheet recommendations
130597 move common qspi stuff to socfpga.dtsi Need to put the common QSPI parameters in the socfpga.dtsi instead of repeating them for each device
209407 Clock Managers Reported from Linux Kernel are incorrect "$cat /sys/kernel/debug/clk/clk_summary” displays incorrect debug clocks, random values for disabled clocks
