Update to latest toolchain version #19

Closed johandc closed 11 years ago

johandc commented 11 years ago

There is a new release available of the AVR toolchain. The version is now 3.4.1. But i cannot find the source files on atmels homepage. :-1: Does anybody here have insight in where atmel puts these releases?

kblomqvist commented 11 years ago

I guess you mean 3.4.2. It seems like binutils have been updated to 2.23.1 and GCC to 4.4.7. Newlib is still old 1.16.0 :(

Patches are here http://distribute.atmel.no/tools/opensource/Atmel-AVR-Toolchain-3.4.2/avr32/

But where are the header files?

johandc commented 11 years ago

No, i actually meant 3.4.1. The release of 3.4.2 happened less than 24 hours ago. It's so fresh that there is still no downloadable packages, nor headers for that matter.

I really wish that Atmel would start giving full access to their toolchains.

Atmel's respond:

Dear Cusstomer There are some issues while publishing the toolchain in the Site this time. The downloaded one is seems to be incomplete. This is reported and complete toolchain is expected to be published in the site soon.

johandc commented 11 years ago

The sources for 3.4.2 as well as the headers are now available on atmel.com. http://www.atmel.com/tools/ATMELAVRTOOLCHAINFORLINUX.aspx

johandc commented 11 years ago

Just downloaded the pre-compiled 3.4.2 toolchain. And they have completely removed avr32-gdb :( Seems like support for linux gets worse for every day that passes.

kblomqvist commented 11 years ago

How did you even used gdb before? avr32-gdbproxy hasn't been there a while.

johandc commented 11 years ago

Oh, it hasn't? How are we supposed to do debugging on AVR32 then?

johandc commented 11 years ago

Really bad news from Atmel:

Dear Customer,

Since atmel studio backend is present for debugging it is stopped working on GDB. In this version only linux 64 bit removes GDB.but it is intended to remove GDB from all versions. So for debugging, you can use Atmel Studio or its toolchain(in windows), or use previous version for linux.

Sorry for the inconvenience caused.

Best Regards, Matt Qian Atmel Technical Support Team

Yep that's sad, but as far as I know, they have considered to add gdbproxy to their new atprogram command-line tool. We can just hope that it will be available for Linux as well. However, unit tests can beat in system debugging I think. I'm just setupping unit tests for Aery32 framework and researching what would be the best way to mock AVR32 registers (avr32/io.h).

I have tried to build with these changes, https://github.com/aery32/avr32-toolchain/commit/5276d91597b2224bbf75ccc7d321c30b243a25b5

But got an error:

*** BFD does not support target avr32-unknown-none.
*** Look in bfd/config.bfd for supported targets.

Edit: AVR32 patches weren't applied correctly because of the changed directory structure. Building now.

Try https://github.com/aery32/avr32-toolchain/tree/wip/gh-19

Although everything builds up, avr32-gcc --version shows wrong version for me.
