Firmware update procedure

• obtain and build the VME programmer (srunner_vme) and IO32 test program (test_VMENIMIO32):
  • mkdir $HOME/packages
  • cd $HOME/packages
  • git clone https://bitbucket.org/ttriumfdaq/vme # get the repository, done once
  • cd vme
  • git pull # get latest version
  • make -k srunner_vme.exe srunner_vme_gef.exe test_VMENIMIO32.exe test_VMENIMIO32_gef.exe

• read the firmware revision from VME register 0:
  • ./test_VMENIMIO32_gef.exe --addr 0x800000 --read 0

• write FPGA firmware into the flash memory using the VME programmer:
  • ./srunner_vme_gef.exe -program -256 vmeio.pof 0x800020

• reboot the FPGA into the new firmware:
  • ./test_VMENIMIO32_gef.exe --addr 0x800000 --reboot

Firmware registers

vmeio register set is a mix of IO32 registers and chronobox registers.
