1. Status: EPICS on Xilinx FGPAs Peter Zumbruch GSI

2. April 17, 2008 Status: EPICS on Xilinx FPGA - 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)

3. April 17, 2008 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

4. April 17, 2008 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

5. April 17, 2008 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)

6. April 17, 2008 Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI 6 Status (2) Install EPICS on/in image Compile locally EPICS : prepared/in test) develop configuration files for cross compile ( : prepared/in test) ppc architecture uClinux OS cross compile EPICS for ppc/os which compiler to use?

7. April 17, 2008 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

8. April 17, 2008 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

9. April 17, 2008 Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI 9 Details: Cross Compiler - Problems configurations differ (gcc/g++ –v) eabi Thread model nfp with- newlib with- cpu:405 with- headers with- float=soft c++ disable- nls with- gnu-ld EDK single uClib?posix powerpc-eabi-{gcc,g++,ar,ld} doesn't find cc1, cc0 when compiling

10. April 17, 2008 Status: EPICS on Xilinx FPGA - Peter Zumbruch, GSI 10 Problems (2) If cross-compile succeeded... get knowledge how to get back to FPGA...
