This is commandline update utility for OLS - OpenBench Logic Sniffer. Logic Analyzer created by Dangerous Prototypes (http://dangerousprototypes.com).
This tool uses parts from Diolan's fw_update tool to talk to the bootloader. Serial port routines first written by Piotr Pawluczuk for pirate-loader, adapted and improved to better fit this project.
So far supported input file types are:
- Binary
- Intel Hex
- Xilinx bit file
All input files are autodetected.
- linux:
- cdc_acm support in kernel
- libusb 1.0 (install libusb-1.0.0-dev)
- autoconf (to build from the GIT repository)
- Windows:
- cdc acm driver
At first do this, then follow the tarball instructions
$ autoreconf --install
$ ./configure
$ make
$ make install
I suggest to use --prefix parameter for configure.
To use BOOT mode (reading/writing the PIC), you will first need to press RESET while the PGC and PGD terminals are jumpered. The ACT and PWR LEDs will be lit. Note that this is different from resetting while pressing the UPDATE button, which is for FPGA firmware update.
In BOOT mode, the device will identify itself (see it with lsusb on linux) as 04d8:fc90 whereas in warm (logic analyser operating) mode, the device will be 04d8:fc92.
You may need to run ols-fwloader as root (sudo ols-fwloader ...) to use the USB device directly in BOOT mode.
Read current OLS PIC firmware into a file:
ols-fwloader -f BOOT -t HEX -R -r current-pic-firmware.hex
Write PIC firmware with verification, enter bootloader first:
ols-fwloader -f BOOT -n -P /dev/ttyACM0 -V -W -w new-firmware.hex
Write FPGA bitstream (HEX):
ols-fwloader -f APP -P /dev/ttyACM0 -W -w bitstream.mcs
Write FPGA bitstream (BIN):
ols-fwloader -f APP -P /dev/ttyACM0 -W -w bitstream.bit -t BIN
