Usage: openFPGALoader [OPTION...] BIT_FILE
openFPGALoader -- a program to flash FPGA
--bitstream arg bitstream
-b, --board arg board name, may be used instead of cable
-c, --cable arg jtag interface
--ftdi-serial arg FTDI chip serial number
--ftdi-channel arg FTDI chip channel number (channels 0-3 map to A-D)
-d, --device arg device to use (/dev/ttyUSBx)
--detect detect FPGA
--file-type arg provides file type instead of let's deduced by
using extension
--freq arg jtag frequency (Hz)
-f, --write-flash write bitstream in flash (default: false, only for
Gowin and ECP5 devices)
--list-boards list all supported boards
--list-cables list all supported cables
--list-fpga list all supported FPGA
-m, --write-sram write bitstream in SRAM (default: true, only for
Gowin and ECP5 devices)
-o, --offset arg start offset in EEPROM
--pins arg pin config (only for ft232R) TDI:TDO:TCK:TMS
--quiet Produce quiet output (no progress bar)
-r, --reset reset FPGA after operations
--spi SPI mode (only for FTDI in serial mode)
-v, --verbose Produce verbose output
-h, --help Give this help list
-V, --Version Print program version

--fpga-part arg fpga model flavor + package
--freq arg jtag frequency (Hz)
-f, --write-flash write bitstream in flash (default: false, only
for Gowin and ECP5 devices)
--index-chain arg device index in JTAG-chain
--list-boards list all supported boards
