Here are all the flash images for the production of the RC2 batch:
They contain the latest 1.0RC1 SoC (which is merely a bugfixed 0.9) and the
first release of Flickernoise, which is becoming usable though some features
are still missing. Nonetheless, this release already supports (among others):
* patch rendering (same features as demo firmware)
* patch editing in the GUI
* OpenSoundControl (OSC) UDP server, based on a modified liblo
* automatic patch switching (with no delay anymore) on keyboard, MIDI, IR and
OSC events (configurable in the GUI)
* DMX inputs and outputs to patches (configurable)
* OSC inputs in patches
* variable monitor
* DMX table (512 channels)
* DMX "spy"
* desktop wallpaper
Some features from RTEMS:
* memory card (read only) - need to find a way to generate the CRCs at a decent
speed for writing (card is used in SD mode, need one CRC16 for each of the 4
* Network File System (NFS) - reading often works OK, but writing depends on
your luck. Don't know if the crappiness comes from the NFS code or from some
bug in the Ethernet driver, need to check on other RTEMS BSPs.
* flash partitions (read only) - currently using the MSDOS filesystem, need to
port YAFFS (JFFS2 is hard to port cleanly from Linux, there's an eCos port but
* shell running on the serial port
Flashing and testing procedure:
1. connect the Xilinx JTAG cable and apply power to the board
2. run prod-flash.sh to flash all the images that are common to all boards:
Flashing all those images is very slow (21 minutes for me). The JTAG/serial
pod (which we'll use later) should be much faster than the Xilinx cable and
The prod-flash.sh script suppresses all the Impact output, you may want to edit
it if you want to see the messages that are printed.
3. the MAC address is contained in the rescue BIOS. Run flash-mcs.sh with one
of the bios-rescue-xx.mcs files as parameter (replace xx with the last two
digits of the MAC address).
For example, the command:
will set the board's MAC address to 10:E2:D5:00:00:17.
Flashing the rescue bios takes 30 seconds.
Later (with the UrJTAG software and the JTAG pod) we'll use a more automated
and faster way to set the MAC addresses...
4. power-cycle the board
5. press the middle pushbutton, the Flickernoise desktop should appear on the
VGA monitor in < 10s.
6. power cycle the board
7. press the middle pushbutton with the first pushbutton held at the same time,
to boot in rescue mode. The splash screen should indicate "RESCUE MODE" at the
bottom, and Flickernoise should then similarly start.
8. run the test program as explained in
