Ejtag Tiny Tools: Software Top

This is your memory Swiss Army knife. Use it to:

Scenario: A home router (MIPS 24Kc core) has corrupted U-Boot in NOR flash. The CPU cannot boot, and no serial console output appears. Using EJTAG Tiny Tools with a $5 FTDI 2232H dongle:

“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.” — Brian Kernighan. The EJTAG Tiny Tools Software Top helps you be just smart enough, without unnecessary cleverness. ejtag tiny tools software top

The software typically consists of several layered components, with ejtag-tiny as the main host tool interacting over USB/serial to an FTDI or bit-bang JTAG adapter.

ENTT2 is relatively inexpensive compared to larger, generic programmers while providing better results for specific NAND tasks. This is your memory Swiss Army knife

: Specialized for working with NAND, eMMC, and NOR flash. It supports complex operations like bad block management, ECC correction, and logical partition reading/writing. SPI Tiny Tools (SPI_TT)

The Software Top ensures that:

I’ll provide an analysis of the top-level software architecture for — a lightweight, open-source debug interface for MIPS EJTAG-compatible targets, often used with FPGA or embedded CPU debugging.

This indicates a complete lack of communication. Verify that the Reset (TRST/SRST) lines are wired correctly and that the processor is not held in a permanent reset state.
