[edit] What's new in release 1.0.0

[edit] Changes in the AVR32 GNU Toolchain

[edit] GCC

  • Added builtin functions for all DSP instruction. Fixed builtins which previously

did not work.

  • Use ggc_malloc() instead of xalloc() for data structures to be garbage collected.
  • Fixed problem with recognizing certain load/store address formats. [#4606]
  • General cleanup of avr32 port.

[edit] libavrtools

  • Upgraded from 0.9.0 to 1.0.0.
  • General cleanup.
  • Fixed problems with events.
  • Added getSignOnData() method to JtagIceMkiiDriver class.

[edit] libavr32ocd

  • Upgraded from 0.9.0 to 1.0.0.
  • Major cleanup and interface changes. Library major version increased to 2.
  • Fixed problems halting CPU. Will now try harder with ABORT and RES flags.
  • Improved handling of user interrupts (Ctrl-C)
  • Ensure JTAGICE mkII firmware >= 4.0 is used. [#4625]

[edit] avr32program

  • Upgraded from 0.9.0 to 1.0.0.
  • Fixed problem autodetecting .bin files if path contained multiple '.'.[#4491]
  • The 'program' command now takes new options '--reset' and '--run'.
  • The 'writeregs' command now prints status after each register write.
  • The 'cpuinfo' command output has been reformatted. Some fields fixed.
  • General cleanup of code and output.

[edit] avr32gdbproxy

[edit] Changes in the AVR32 Linux environment

[edit] AVR32 Linux kernel

  • Updated Linux sound driver for AC97 with capture support.
  • Updated Linux sound driver for AT73C213 with ALSA mixer support.
  • Added Linux driver for external interrupts.
  • Use generic sys_rt_sigsuspend implementation. Fixes problems with multithreaded applications

[#4571].

  • DMAC driver returns -EINVAL instead of BUG()'ing when block size is too large.
  • Prevent at32_enable_device() from causing BUG() when portmux_enable_device() fails.
  • Added missing irq_get_type() and irq_set_type() functions.
  • Fixed ptrace bug preventing gdbserver from working properly.
  • Prevent SM from masking precious clocks.
  • Fixed bug in SM interrupt call.
  • Added setup and free functions to SM.
  • __get_user_check() and __put_user_check() macros no longer reference arguments multiple

times. This fixes a problem where read()'ing from a TTY would return 0 between each character [#4672].

[edit] Changes to U-Boot

  • Don't enable devices which the Linux kernel enables itself.
  • Enable core networking commands and both network interfaces (MACB0/MACB1)
  • PLL configuration changed to use divider 1. Stabilizes clock, necessary for VGA output.

[edit] Other changes

  • Added ncurses library.
  • Added ALSA utilities (alsamixer, aplay, arecord etc) and library.
  • build-linux-environment.sh will not work in Windows( cygwin). However, not all packages

will build properly yet.

  • Fixed missing patches from CD image required to build development tools with build-devel-environment.sh

script. [#4757]

  • Merged patchsets into single avr32 patches for Linux, binutils, gdb, uClibc and U-Boot.
  • binutils: Fixed incremental linking in the standalone linker. Added support for GC

(garbage collection) sections.

[edit] Documentation

  • User Guide updated. Chapter on Linux development added.

[edit] What's new in release 0.93 (beta 4)

  • Additional appnotes included.
  • Updated on-board web page.
