| - | - PetaLinux needs a patch for sed (in Debian Strech bash and sed are too new for PetaLinux). \\ From Xilinx forum: "The problem is the "ls | sed" command sequence in the last line generates a multi-line response while the bash read builtin only reads a single line. I added a wrapper around sed that translates the newlines generated into spaces and the installer completed as expected on an otherwise stock Debian stretch install." -- the default Xilinx workaround is to... replace the system sed with the wrapper, which is really nasty solution. Let's make it properly:\\ Create sed path script (assume example name ''sed.sh'') and make it executable: <code> | ||
| - | #!/bin/sh | ||
| - | # Remove newlines if called by the silly Xilinx PetaLinux 2018.1 installer | ||
| - | if [ "$2" = "s/^.*minimal-\(.*\)-toolchain.*/\1/" ] ; then | ||
| - | /bin/sed "$@" | tr '\n' ' ' | ||
| - | else | ||
| - | /bin/sed "$@" | ||
| - | fi </code> | ||
| - | - Create source script which will later set the PetaLinux enviroment. Assume example name ''settings_petalinux_2018.3.sh'': <code> | ||
| - | alias sed="<path_to_sed_wrapper_script>/sed.sh" | ||
| </code> | </code> | ||
