Parallella Community

And it solved my connection issue

The new release seems to fix most of my problems.

Since I need to rebuild the kernel to enable the UIO driver, I have noticed that the parallella_defconfig on github contains "XILINX_DEVCFG=y", which is invalid (produces a warning). It should be "CONFIG_XILINX_DEVCFG=y" instead. Also, parallella_defconfig enables support for many other platforms and related drivers, which increases the kernel size a bit.

Sorry for the late reply, and thanks for the update!

+1 Ola
Everything's all right O_O I'm impressed ; since I don't have internet during the week, since your scripts are well documented (+1 again), I could squeeze the done part (fetching) and build everything
Even gcc-explorer works, I can work in good conditions

Many thanks, Ola.
To be exhaustive, could you please update the doc ?
1/ the options -C -a -r x86_64 are obsolete or I did not understand something - it detects my x86_64 and compiles accordingly.
2/ for the existing Fedora esdk doc:
- compat-guile1.8 dependancy ; currently guile is 2.0 (since 2014 iirc), installing it won't include compat-guile1.8
- xzip dependancy does not exist ; my best guess is it existed a long time ago, with Fedora versions <= 11 (~ 2008) ; after this xz was adopted.
I've searched xzip quite a long time, but it was never required or even existing for current Fedora.
2015.1 and 2016.3.1 did build successfully without any xzip, I guess it is xz.

Have a nice day

I am a little confused. I managed to cross-compile the kernel after setting up a ubuntu 15.10 install. This gave me:

Linux version 4.4.0+ (mikei@mikei-virtual-machine) (gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu1) ) #1 SMP Mon Aug 1 16:58:21 CEST 2016

I used the rootfs from the 2016.3 image by loopback mounting it and rsyncing to the sd card

gcc --version gives:
gcc (Ubuntu/Linaro 4.9.2-10ubuntu13) 4.9.2
Copyright (C) 2014 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO

So it appears that the kernel is built by gcc5.2.1 and the rootfs by gcc4.9.2.

Am I correct in assuming that as long as I compile my Kernel modules under the same GCC as the kernel, and that I keep the userspace at 4.9.2 all should be OK?

Also Kudo's for getting the console serial port working. Should I solder a pull-up to 3.3V on the rx line so that there are no spurious interrupts when I am not connected to my serial adapter?

It doesn't matter if kernel and userspace have been built by different compilers, as long as the same compiler is used for kernel and kernel modules. In userspace, the library versions are more important (and, for C++, they are somewhat tightly coupled to the compiler). To play it safe, don't cross-compile the applications.
