Add ARM builds to the boards manager package

[majenkotech]

I have compiled a Linux 32-bit toolchain (since I couldn't find it in the build.xml, nor guess the URL).

Download: http://cdn.majenko.co.uk/esp/xtensa-lx106-elf-linux32.tgz

ARMhf version is compiling at the moment. I'll provide a link for that too when it's done and packaged.

Linux 32-bit esptool is up as well: http://cdn.majenko.co.uk/esp/esptool-0.4.4-linux32.zip
And so is the ARMhf version: http://cdn.majenko.co.uk/esp/esptool-0.4.4-linux-armhf.zip

Huge thanks for the toolchain! Did you build it using crosstool-NG? If so, which git revision was it?

[igrr]

Also, why is esptool in a zip archive? I thought I changed make dist to generate .tar.gz archive for Linux and Mac OS...

[igrr]

I have added the 32-bit tools to the board manager package.

Yes, crosstool-NG from https://github.com/jcmvbkbc/crosstool-NG - the HEAD of the lx106-g++ branch

I manually packaged esptool as .zip because the 0.4.3 version is packaged as .zip, and my UECIDE package build scripts expect it to be .zip. I can do a .tgz for you as well if you prefer.

By the way, the ARM compiler is nearly done - 871 minutes compiling so far and it's on cross-gdb.

Actually, "make dist" makes a zip file. The repo I am using is https://github.com/igrr/esptool-ck

[igrr]

Actually it should be tar.gz (I made that change yesterday):
igrr/esptool-ck@d564b01

I switched to tar.gz because Arduino Boards Manager didn't preserve permissions for executable files inside .zip files, switching to tar.gz did the trick.

Regarding ARM — do you know if there is a version of Arduino for ARM?

[majenkotech]

Ah - my linux32 repo pre-dated that change (pulled, and built now - http://cdn.majenko.co.uk/esp/esptool-0.4.4-linux32.tar.gz ). My ARM copy of the repo was new enough, but it can't identify that it's linux, so it builds it as a .zip.

matt@armadillian:~/esptool-ck$ uname -a
Linux armadillian 3.18.11+ #15 PREEMPT Sun May 3 17:18:11 BST 2015 armv6l GNU/Linux
matt@armadillian:~/esptool-ck$ uname -p
unknown 
matt@armadillian:~/esptool-ck$ uname -m
armv6l

I'll manually package it for now.

And yes, Arduino is available for ARM. Only seems to be 1.0.5 in the default repository though, but no reason why you can't use any other Linux download of Arduino - it's Java after all.

[igrr]

does uname -s tell that it's Linux?

[majenkotech]

Better still, there's a fix for ARM. Also a package: http://cdn.majenko.co.uk/esp/esptool-0.4.4-linux-armhf.tar.gz

[majenkotech]

By the way - uname -m is probably the better way of detecting what the architecture is:

Linuxx 64 = x86_64
Linux 32 = i686
Linux ARM = armv6l

[igrr]

If you can change the makefile to use uname -m and test on 86 and ARM, then please do add this to your pull request.

[majenkotech]

Works nicely - just built packages on all three platforms as Linux in tar.gz

[majenkotech]

ARM compiler now up: http://cdn.majenko.co.uk/esp/xtensa-lx106-elf-linux-armhf.tgz

Press F5 and use the real URL ;) You grabbed that in the 3 seconds it was wrong.
