ToolZ is Hack Tool, it is hacked together thing, very beta, very useful, very Hacked.
- JTAG chain scan: ToolZ will show the user EEPROM coded ID for many FTDI dongles, and then try to make JTAG scan.
- FPGA Configuration, 6 and 7 series
- SPI Flash indirect programming
- Built in TCL 8.6
- Boundary scan, can invoke from TCL scripts
This is maybe not much but it has helped me many many times, last example is #Secure microSD Vault - Xilinx Vivado refused to flash the Micron SPI Flash, ToolZ did not complain just worked.. and so on..
