The command usage and options are identical forsdsccandsds++.
Options not recognized bysdsccare passed to the ARM cross-compiler. Compiler options within an-sds-hw ... -sds-endclause are ignored for the-c foo.coption whenfoo.cis not the file containing the specified hardware function.
When linking the application ELF,sdscccreates and implements the hardware system, and generates an SD card image containing the ELF and boot files required to initialize the hardware system, configure the programmable logic and run the target operating system.
When linking application ELF files for non-Linux targets, for example Standalone or FreeRTOS, default linker scripts found in the folder–Wl,-T –Wl,linker option.
When building a system containing no functions marked for hardware implementation,sdsccuses pre-built hardware when available for the target platform. To force bitstream generation, use the-rebuild-hardwareoption.
Report files are found in the folder_sds/reports.
When running Linux applications that use shared libraries, the libraries must be contained in the root file system or SD card, and the path to the libraries added to the LD_LIBRARY_PATH environment variable.
Optional PL Configuration After Linux Boot
Whensdscc/sds++creates a bitstream
.binfile in the
sd_cardfolder, it can be used to configure the PL after booting Linux and before running the application ELF. The embedded Linux command used is
cat bin_file > /dev/xdevcfg.
