Peter Lawrence has been working on using a PIC as a CMSIS-DAP ARM debugger. I wanted to see what was feasible in the way of a very-low-cost ARM board. OK, that doesn’t sound original, but stick with me. The solutions that I’ve seen (Tweeny, McHck, mbed, etc.) are limited to wholesale firmware updates. Press a […]

DSJTAG – USB JTAG debugger and programmer for both Xilinx and Altera IDEs
Seeed has a cheap JTAG programmer/debugger for both major FPGA/CPLD brands. It emulates both the Xilinx Platform USB Cable and Altera USB blaster JTAG programmers with a flip of a switch. As a Xilinx Platform USB Cable it is supported by the manufacture’s iMPACT, ISE, Chipscope and EDK software bundles. The firmware is upgradable through […]
Bus Blaster v2 testing
We’ve just completed verification of the Bus Blaster v2 JTAG debugger. V2 is much more flexible than v1, and uses a programmable logic chip (CPLD) for the buffer. The logic chips in v1 were expensive to source and place, but v2 uses a $1 CPLD with a bunch less pins to solder and inspect. Bus […]
Improving the MSP430 debugger
Travis Goodspeed studied the MSP430 FET debugger, and redesigned it with a bunch of improvements: A FET is any Flash Emulation Tool containing an MSP430F1612, including the FET UIF and EZ430 debuggers. I am happy to announce my own variant of the MSP430 FET debugger. My variant is compatible with a patched version of the […]
