cd alluvium
python3 -m alluvium -hThe basic form of use is: python3 -m alluvium <host_or_IP> <command> ....
The entry point provides a number of sub-commands.
$ python3 -m alluvium 192.168.19.4 status

SR2 0b00000000 [es , ps ]
CR1 0b00100100 [lc1 , lc0 , TBPROT, dnu, bpnv , TBPARM, quad , freeze]

In addition, two special address alias names may be given: gold (0) and app (8M).
Also, the read command accepts the special size bit to read the size of a
xilinx bit file currently stored in flash.
# read out fixed size
$ python3 -m alluvium 192.168.19.4 read 8M 0x100 | hexdump -C
...
# read size from xilinx bit file header
$ python3 -m alluvium 192.168.19.4 read gold bit -f current-gold.bit
...$ python3 -m alluvium 192.168.19.4 program appl new-appl.bit
...To clear the indication of a previous error
$ python3 -m alluvium 192.168.19.4 clear
...# Clear SRWP and block protect
$ python3 -m alluvium localhost:8804 setup --sr1 0
...
# enable SRWD, BP2, and BP1
$ python3 -m alluvium localhost:8804 setup --sr1 0b10011000
...
# Initial setup of OTP bits. (Caution, read the datasheet first)
$ python3 -m alluvium localhost:8804 setup --sr1 0 --cr1 0b00100100
...More than one device may be manipulated in parallel. Alluvium will exit after all operations complete or timeout, and will return with code 0 only if all operations succeed.
While the following works for all commands, it is not useful for commands which write a output file as that output would be corrupt.
In addition to simple host/IP address and port, a comma seperated list of such entries may be given.
$ python3 -m alluvium 192.168.19.4,192.168.19.56 statusFor larger numbers of devices, a file of such entires may also be given.
$ cat device.list
192.168.19.4
192.168.19.56
192.168.19.100
$ python3 -m alluvium device.list statusFor software testing, a simulation is available.
python3 -m alluvium.sim

...The simulator process will repond to "w\n" annd "r\n" on stdin
