4. PCA-FE2 board firmware and FPGA updating and
recovery
4.1 PCA-FE2 board firmware and FPGA updating
If the software (CXDI Control Software NE or CXDI Controller RF) has been installed in the
Image Capture Computer, the operations for the PCA-FE2 board firmware and FPGA updating
can be performed using the Ferry type FPD maintenance tool which is a service tool. The
updating is performed while power is supplied using the battery or wiring unit. Since the pre-
updated program will continue to run even after the updating, booting is initiated using the new
program either by removing the battery and re-installing it or by turning the power off and then
back on. For details of the operating procedure to update the firmware and FPGA using the ferry
type FPD maintenance tool, refer to the separate “CXDI Control Software NE” service manual.
4.2 PCA-FE2 board firmware and FPGA recovery
A boot switch is provided near the battery connector of the detector for recovery purposes when
the data cannot be written correctly for some reason during the updating of the PCA-FE2 board
firmware or FPGA, resulting in trouble with the board operation.
Follow the steps below to boot operation in the backup mode.
1) Remove the battery.
2) Set the boot switch to the backup mode.
3) Install a battery which has been charged.
* Updating is possible only when the remaining battery charge level is 60% or more.
Updating is recommended using a battery with a full charge.
4) With a wired connection using the wiring unit, connect the detector and AC/DC box using
the detector cable, and set the power of the AC/DC box to ON.
5) Press the power switch of the detector for at least a second to turn on the unit’s power.
Operation now starts up using the backup firmware and backup FPGA. When the power is
turned on with the boot switch at the backup mode setting, the backup code firmware is loaded
into the SDRAM, and operations are performed. With the backup firmware, the FPGA config
data for backup is written directly to the FPGA internally, and operation starts up.
NOTE: During startup from the backup code, the LINK LED (blue-green) blinks, its
brightness changing gradually. The LED stops blinking when startup is complete, so it
is necessary to wait at least 30 seconds.
The firmware or FPGA updating can be performed using the service tool while in the backup
mode boot status.
