Release Notes

Release Date:  July, 2013


This is Release of AM335x Linux PSP. This 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 Linux kernel and U-Boot software in this release are based on the following open source repositories:

Component Version Base Repository Base Tag (or commit id)
Linux Kernel v3.2;a=summary d5720d33bc7c434f9a023dbb62c795538f976b7a
U-Boot 2013.01;a=summary v2013.01

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/Commit Id
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 540aa6fbb0c9274bda598f7e8819ed28259cad6b

What's Supported:

The release is a minor release. Refer to the AM335x-PSP Release Notes.

New in this Release:

  • Support for PG 2.1 and PG 2.1 EVMS
  • Support for Beaglebone Blackl. HDMI support not included.


  • PM
    • Enable RTC wakeup for standby on PG 2.1 silicon


  • NOR support

Fixed in this Release


Fix for Advisory 1.0.15 "ARM Cortex-A8: OPP50 Operation on MPU Domain Not Supported"

Fix for Errata i103 "Delay needed to read some GP timer, WD timer and sync timer registers after wakeup (OMAP3/4)"


  • musb: gadget: rxdma fix when data rcvd before usb request queued
  • cppi41: g_multi gadget fixes in dma mode


Attempt to minimize the impact of Advisory 1.0.24 "Boot: System Boot is Not Reliable if Reset is Asserted While Operating in OPP50"

Known Issues:

  • ADC: No trigger method supported.
  • PM: Standby:
    • USB connect/Disconnect wakeup will not work, since we only support GPIO based wakeup and use MPU_WAKE patch and connect/disconnect goes via different patch through PHY_WAKE to CM3.
    • Ethernet wakeup is not tested, since ETH PHY wakeup signal is not connected to GPIO.
  • PM: Smart Reflex:
    • Harmless warning message "smartreflex smartreflex: get_errvolt: SR 1: Same AvgError for 2 s"
  • SDOCM00100099 DUT does not go into suspend state if USB DMA is enabled
  • SDOCM00099909 There is a mismatch between Uboot and kernel regarding SPi partition table
  • SDOCM00099624 Resume fails when dual_emac option is not enabled in config
  • SDOCM00099622 Audio/Video capture test results in uvcvideo: Failed to resubmit video URB (-1).
  • SDOCM00099621 USB reset events seen with simultaneous data and control traffic in PIO mode
  • SDOCM00099444 Internal ADC clock division check not required
  • SDOCM00099314 AM335X: USB: minor audio glitch/noise observed when new device inserted to one usbport while playing audio through other port
  • SDOCM00100316 USB Mouse HID event stops being a wakeup source if preceded by Mouse disconnect/connect wakeup source
  • SDOCM00100303 DUT does not go into suspend state when it is acting as USB MSC device
