  1. Status: EPICS on Xilinx FGPAs Peter Zumbruch GSI

  2. Strategy • Hardware ML403 • Based on VMware image • provided by KIP (N.Abel) • containing all necessary Tools • Xilinx ISE 8.2 • necessary IP cores (later) • uClinux running on ML403 (N.Abel) Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  3. Strategy (2) • Install EPICS on/in image • Compile locally EPICS • develop configuration files for cross compile • ppc architecture • uClinux OS • cross compile EPICS for ppc/os • EPICS base • IOC, (one) i.e. (static) executable Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  4. Strategy (3) • Include this into image to upload to FPGA • Tests • IOC locally • IOC remote access • move to other Virtex 4 platforms Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  5. Status • Hardware ML403 • Based on VMware image  • Ethernet IP core license (invalid license) • uClinux running on ML403 (N.Abel) Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  6. Status (2) • Install EPICS on/in image • Compile locally EPICS • develop configuration files for cross compile (: prepared/in test) • ppc architecture • uClinux OS • cross compile EPICS for ppc/os • which compiler to use? Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  7. Details: Configuration Files • EPICS Build systems uses sets of CONFIG files (Makefiles included in build process) to define necessary informations • -I , isystem • -L • CFLAGS, CXXFLAGS, FLAGS • (CROSS)-COMPILER • HOST/TARGET OS • ... prepared for linux-x86.uClinux-ppc405 Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  8. Details: Cross Compiler • Two different gcc-based configurations available: • Xilinx EDK • powerpc-eabi-{gcc,g++,ar,ld} • 3.4.1 • uClinux Distribution • powerpc-linux-uclibc-gcc • no g++ available • (Toolchain not in VMware image) • 3.4.2 Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  9. Details: Cross Compiler - Problems • configurations differ (gcc/g++ –v) • powerpc-eabi-{gcc,g++,ar,ld} • doesn't find cc1, cc0 when compiling Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI

  10. Problems (2) • If cross-compile succeeded ... • get knowledge how to get back to FPGA ... Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI
