Release Notes

Release Date:  December 21, 2012


This is release of the AM335x Linux PSP. The PSP is part of the Sitara SDK. This PSP release supports:

The Linux PSP serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments silicon.

The code base for Linux kernel, U-Boot and power management firmware included in this release is hosted at the following repositories:

Component Repository & Branch Release Tag
Linux Kernel;a=shortlog;h=refs/heads/v3.2-staging
(The kernel obtained directly from the above repository needs PM firmware to build when building using default configuration. Link to PM firmware repository containing the firmware binary is available below in this table. Copy the firmware binary .bin file into the firmware/ folder of the kernel sources)
U-Boot;a=shortlog;h=refs/heads/amsdk- v2011.09_AM335xPSP_04.06.00.08
Power Management Firmware;a=shortlog;h=refs/heads/master AM335xPSP_04.06.00.09-rc2


Tool/Component Description Release Version Required for
Code Composer Studio (CCS) IDE and ARM compiler Building CCS based flash writers
Arago Toolchain GCC ARM cross compiler 2011.09 (GCC 4.5.3) Building Linux kernel, U-Boot, Linux examples
Filesystem Target filesystem NA Linux boot

Feature Addition:

  • RTC Runtime PM Support
  • TSC/ADC: IIO and MFD framework migration
  • ADC driver support
  • tps65217: Set PMIC to shutdown using RTC module
  • USB PHY Wakeup support

    Note: Since in DS0 usb wakeup can not be supported on current silicon, by default USB wakeup is kept disabled.

  • CPSW: Promiscuous mode support
  • CPSW: Support the HWTSTAMP ioctl and the CPTS

Bug Fixes and Cleanup:

  • PWM: ecap: Resets the PWM output to low on stop
  • net: ethernet: fix kernel OOPS when remove davinci_mdio module
  • SDOCM00094923: NFS mount fails with "DHCP/BOOTP: ignoring delayed packet" messages
  • mtd: nand: omap: fix race condition in omap_wait()
  • mtd: nand: omap2: Fix for uncorrectable error
  • mtd: nand: omap2: Fix bit flip in data area due to bit flip in OOB
  • mtd: nand: omap2: Fix ECC read for 16-bit NAND part
  • ARM: OMAP2+: am335x: Fix xbar channel implementation for odd channels
  • SDOCM00085443 - ARM: OMAP2+: am335x: Change the wdt1 func clk src to per_32k clk
  • SDOCM00086716 - Fix omap_hwmod wdt2: _wait_target_disable failed error message
  • ARM: OMAP: AM33XX: PM: Fix potential deadlock in resume process due to MPU leaving GPIO0 enabled
  • USB:
  • Build warning fixes
  • usb: musb: Fixes for invalid parameter passed for dev_dbg()
  • SDOCM00097396 - Babble workaround fix
  • SDOCM00097395 - Rx race condition
  • SDOCM00091956 - The debugfs support for usb testmode
  • SDOCM00091464 - The UVC camera doesn't capture frames after several times of off and on
