I've been working on setting up hardware testing in my lab at home. The Device Tree documentation we have currently is horrible:
https://docs.rtems.org/branches/master/user/exe/device-tree.html It's a list of command and descriptions about what it is but not what they do. For instance look at section 8.8.1. The 'dtc' command? Where do I get it? I have one on FreeBSD .. what if I'm running Linux is it the same 'dtc' command? I have FreeBSD from 6 years ago will that work or what about the CURRENT machine I have. There is no minimum version. Also, I'm aware this command exists on Linux. except: root@beer:~# dtc bash: dtc: command not found root@beer:~# apt-get install dtc Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package dtc This on a Debian 10 machine. So let me search for it: root@beer:~# aptitude search dtc p ddtc - Deal with ddts mails p dtc-xen - SOAP daemon and scripts to allow contr p dtc-xen-firewall - small firewall script for your dom0 p python-dtcwt - Dual-Tree Complex Wavelet Transform li p python-dtcwt-doc - documentation for dtcwt p python3-dtcwt - Dual-Tree Complex Wavelet Transform li p sbox-dtc - CGI chroot wrapper script for safer ho Nope, nothing, but of course *I* know what it is the documentation doesn't tell me, though: root@beer:~# aptitude search device|grep -i tree p device-tree-compiler - Device Tree Compiler for Flat Device Trees [install] root@beer:~# dtc -v Version: DTC 1.5.0 Finally.. but now I'm not so sure I'm there because on FreeBSD: verm@peach# dtc -v Version: dtc 0.5.0 compatible with gpl dtc 1.4.7 Are these really the same tool? Which one do I use? What version? How do I even know that the output is correct do I just run the commands blindly and hope it works? FreeBSD is another story. It does have a package called 'dtc' which I had to install to get 'fdtoverlay'...which is interesting because the 'dtc' command exists in FreeBSD as part of the base: root@peach# which dtc /usr/bin/dtc Yet there is no 'fdtoverlay'. I had to install the 'dtc' package -- a command I already have mind you to get 'fdtoverlay'. Again these are things I know how to find but a new user has no chance.. also: root@peach# fdtoverlay -V Version: DTC 1.4.7 It's not even 1.5.. and now I have two 'dtc' commands one in /usr/bin/dtc and another in /usr/local/bin/dtc. Which one do I use and what version. Amar. _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
