Introducing swddude I love the ARM Cortex-M series of microcontrollers. The sheer computational power they pack into a teensy, low-power package is almost embarrassing. But, many Cortex-M parts are small — 4x4 millimeters small — and don’t have the…
Implementation of Serial Wire JTAG flash programming in ARM Cortex M3 Processors The goal of the project was to use the Serial Wire JTAG protocol implemented in the ARM cortex processors for programming the flash memory of it. JTAG was actually imple…
JTAG was the traditional mechanism for debug connections for ARM7/9 parts, but with the Cortex-M family, ARM introduced the Serial Wire Debug (SWD) Interface. SWD is designed to reduce the pin count required for debug from the 5 used by JTAG (includi…
