Usage: easypdkprog [OPTION...] list|probe|read|write|erase|start [FILE]
easypdkprog -- read, write and execute programs on PADAUK microcontroller
https://free-pdk.github.io
--allowsecfuse Allow setting the security fuse.
-b, --bin Binary file output. Default: ihex8
-f, --fuse=FUSE FUSE value, e.g. 0x31FD
-i, --icid=ID IC ID 12 bit, e.g. 0xAA1
--noblankchk Skip blank check before write
--nocalibrate Skip calibration after write.
--noerase Skip erase before write
-n, --icname=NAME IC name, e.g. PFS154
--noverify Skip verify after write
-p, --port=PORT COM port of programmer. Default: Auto search
-r, --runvdd=VDD Voltage for running the IC. Default: 5.0
--securefill Fill unused space with 0 (NOP) to prevent readout
-s, --serial=SERIAL SERIAL value (64bit), e.g. 0x123456789ABCDEF0
-v, --verbose Verbose output
-?, --help Give this help list
--usage Give a short usage message
-V, --version Print program version
Examples:
list all supported ICs:
easypdkprog list
probe IC in socket (can determine IC type/name):
easypdkprog probe
read IC to readout.hex file:
easypdkprog -n PFS154 read readout.hex
read IC to readout.bin file:
easypdkprog -n PFS154 read readout.hex -b
write IC:
easypdkprog -n PFS154 write myprog.hex
erase IC (flash based only):
easypdkprog -n PFS154 erase
start IC in socket (interactive mode): all serial output sent form IC-PA.7 (autobaud detection) is displayed on screen all input from keyboard is sent as serial to IC-PA.0 (using same detected baud as receive)
easypdkprog start
