I have not analyzed it to determine what floating point code is being generated. As soon as we try to FTP to the board, it generates an FP trap on GRMON. When I enabled the floating point context support on the FTP task, it does not crash. But I agree, it is worth trying to figure out where

Hello Alan, I am not sure how Gaisler manages this in their RCC, but I think for standard RTEMS we need additional BSPs (e.g. via leon3_fp.cfg and ngmp_fp.cfg configuration files). On 17/08/15 17:29, Cudmore, Alan P. (GSFC-5820) wrote: Hi, We are currently trying to use the leon3 BSP for

Hi, We are currently trying to use the leon3 BSP for RTEMS 4.11. We have used the 4.10 RCC/Gaisler tools with the Driver Manager in the past, but we would like to be on 4.11 for the SMP support. When I build the 4.11 leon3 BSP, I seem to only have soft-float support. When I try to build with
