EJTAG Tiny Tools was originally written for simple dongles (e.g., Wigglers, JTAGKeys). However, the community has ported it to work with FTDI-based USB adapters (like the FT2232H) using libftdi .
: Allows direct reading from and writing to the flash chip via the CPU's EJTAG port, bypassing the need for an operating system.
: While originally focused on JTAG, modern versions like the USB-F variant support eMMC (up to 20MB/s in 4-bit mode) and UART/SPI protocols.
. They were prized for being small, affordable, and incredibly capable: EJTAG Tiny Tools CPLD
