14.5 Compiler and Busybox Ash Shell Globbing Broken

Jump to solution

Hello all,

 

I have been using Buildroot to build Linux for the zed board and I ran across the issue where the 14.5 compiler breaks the busybox ash shell globbing as described here:

 

http://www.wiki.xilinx.com/Zynq+14.5+-+2013.1+Release

 

I tried the latest tool chain from Sourcery CodeBench and still had the same issues.  When I tried an older toolchain as described on the web page above (CodeBench Lite 2012.03-57), the globbing issue was resolved.

 

I am wondering if anyone knows if Mentor Graphics is working on a solution to this issue and if so, if and when the new toolchain will be incorporated into a new ISE/Vivado release?  I tried to post an inquiry on the Mentor Graphics site, but did not have a proper registration as I am using the Lite version of the toolchain.

 

Thanks,

 

Brett Swimley

Yes, I ran into the same issue and reported it to Mentor. I didn't get any updates for a while though. The workaround I found is to set the optimization level for busybox to anything but '-Os'.

Hmm - I thought I had tried that but maybe I did not change the busybox configuration the way I thought I had.

 

Thanks for the reply.  I may try again using the 14.5 toolchain.

I did rebuild using the current toolchain and -O2 optimization, and the globbing issue is resolved.  I think I overrode my configuration by doing a make clean prior to saving the configuration.

 

Thanks.
