Constructor Details

FirmwareLoader

public FirmwareLoader(BMPTransceiverInterface txrx, BMPBoard board)

Parameters:

txrx - How to talk to BMPs. The specific BMP to talk to must have been bound.

board - Which board's BMP are we really working with.

Method Details

setupRegisters

public void setupRegisters(FirmwareLoader.RegisterSet... settings) throws ProcessException, IOException, InterruptedException

The write part of cmd_xreg from bmpc.

Parameters:

settings - The registers to set.

Throws:

IOException - If anything goes wrong with networking.

ProcessException - If SpiNNaker rejects a message.

InterruptedException - If the communications were interrupted.

FirmwareLoader.UpdateFailedException - If the flash data sector read back does not match what we wanted to write.

setupBitfile

public void setupBitfile(String handle, int slot, FPGA chip) throws IOException, ProcessException, InterruptedException

Set a bitfile to be loaded.

Parameters:

handle - The bitfile handle, matching one of the resources known to this bean.

slot - Which slot to install the bitfile in.

chip - Which chip or chips are to load the bitfile.

Throws:

IOException - If anything goes wrong with networking.

ProcessException - If SpiNNaker rejects a message.

FirmwareLoader.TooLargeException - If the bitfile is too large for the BMP's buffer.

FirmwareLoader.CRCFailedException - If the written bitfile fails its CRC check.

FirmwareLoader.UpdateFailedException - If the flash data sector read back does not match what we wanted to write.

InterruptedException - If the communications were interrupted.

bitLoad

public void bitLoad(boolean postDelay) throws InterruptedException, ProcessException, IOException

Load the FPGA definitions.

Parameters:

postDelay - Whether to do the long delay after the FPGA boot/check

Throws:

InterruptedException - If interrupted while sleeping

ProcessException - If a BMP rejects a message

IOException - If the network fails or the packaged bitfiles are unreadable

FirmwareLoader.FirmwareLoaderException - If something goes wrong.
