Main PCB Firmware Chips
The main PCB has one field-changeable flash memory chip for the M&C firmware. If
necessary, this chip can be removed and a new chip added to allow for additional options,
enhancements, or repairs. See Figure 2-6 for the locations of the field-changeable chips.
The bulk firmware for the FPGA downloads is stored in a non-replaceable flash memory
device. Bulk firmware can be upgraded by reflashing the device through the remote
control port as described in paragraph 2.7. The M&C firmware also can be upgraded by
reflashing through the host por
