: A popular programmer for SPI flash and microcontrollers. Version 2.0 supports advanced features like JTAG emulation for IR PowIRCenter and handles chips larger than 16MB using 3-byte and 4-byte addressing. Easy-NAND Tiny Tools
Manages hardware and software breakpoints. You can set breakpoints on instruction addresses or data watchpoints. When the CPU hits the breakpoint, you regain control via the EJTAG interface to inspect registers or memory. ejtag tiny tools software top
A dedicated utility for SPI-flash chips, often used for BIOS or firmware recovery. : A popular programmer for SPI flash and microcontrollers
By embracing the tiny tools ecosystem and mastering the top software stacks, you turn the daunting EJTAG protocol into a precise, surgical debugging scalpel. You can set breakpoints on instruction addresses or
To help you choose, here is a head-to-head comparison of the top software running on an EJTAG Tiny adapter (Test hardware: Broadcom BCM5357 @ 300MHz):
Let’s explore what makes this toolset a hidden gem for embedded reverse engineering and firmware development.
Direct register access. Read or write the CPU’s general-purpose registers, status registers, or EJTAG control registers. This allows you to single-step instructions or change the program counter (PC) to bypass code.
