December 10, 2014CLBv2, Vidyo Peter Jansweijer Nikhef Amsterdam Electronics- Technology Multiboot Solved 2 Xilinx WebCase: Multiboot in Kintex-7 ◦ “For 7 series, only the 24 bit addressing logic is used in the configuration state machine. Due to this reason we do a right shift of the MSB and discard the LSB 8 bit. Also there are so many extra dummy bytes in the bitstream header when we enable the 32bit option while bitstream generation, to compensate for the LSB 8 bit.” Now able to boot images 0 to 3 (0 being the “Golden”) Watchdog functionality operational (fallback to golden) To-do: Image lock

December 10, 2014CLBv2, Vidyo Peter Jansweijer Nikhef Amsterdam Electronics- Technology WR Switch VLAN tests 3 VLAN support from V3.4 upwards => need to update/flash the switches we received from 7-Solutions. Flashing the switch needs ARM-Boot-ROM USB-loader via front panel “management USB”. The ARM processor has a known bug ( in its USB2.0 therefore need to access this port with USB 1.1http:// Received USB 1.1 hub from 7-Solutions ◦ WR-Switch 119 => v4.1.1 The way back to V3.3.1 is complicated due to Switch Core Board Hardware Rev 3.4 (and not v3.3). Waiting for 7-Solutions to guide us, before a second switch is loaded with v4.1.1 (for VLAN testing).
