Does anyone know how to read the serial number from an Amontec Tiny?
I’m trying to use two of them with the ft2232_serial command in the interface section, but without a serial number I’m out of luck.
We have seven of the Tinys here and if they came in with the serial number on the packing slip, no one wrote it on the device.
Thanks.
I downloaded the development files for libftdi and found some example code that I made trivial hack on to get the serial numbers. With serial numbers OpenOCD does allow two instances to run, Of course you need different port numbers.
Here’s part of my two config files:
telnet_port 4444
gdb_port 3333
daemon_startup reset
interface ft2232
ft2232_device_desc “Amontec JTAGkey”
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8
ft2232_serial “T1P3S2ST”
telnet_port 5555
gdb_port 2222
daemon_startup reset
interface ft2232
ft2232_device_desc “Amontec JTAGkey”
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8
ft2232_serial “T1Q9O61Z”

/* find_all.c
Example for ftdi_usb_find_all()
This program is distributed under the GPL, version 2
I found this in /usr/share/doc/libftdi-dev/examples
on my Ubuntu system and modified it to print the serial number.
This worked to generate the executable:
gcc find_all.c -lftdi -o find_all
