"Maven" is a WiFi-enabled ARM Cortex-M hardware (SWD) debugger and programmer which, through its built-in GDB Server, interfaces directly with the Gnu debugger "GDB" over the local network. This means any host capable of running GDB can be used with Maven. There's an onboard OLED display showing Maven and Target status plus rs232 output from the target. The latter is also available over the network via telnet.
I wanted an ARM debugger/programmer which could be accessed over the network (perhaps even over the Internet) and which did not require an adjacent host PC running something like 'openocd'. I also wanted something which had a built-in terminal server so I could use telnet to access the rs232 debug UART on my target devices. I also wanted the option of powering the debugger via the target, giving complete isolation from the host's power supply.
Maven uses the same underlying hardware as wAVR, also listed on Tindie, but with very different firmware and an additional "paddle" board which interfaces Maven's 10-pin target connector with most of the standard ARM JTAG/SWD connectors. At the present time Maven natively supports many ARM Cortex-M micro controllers from Microchip/Atmel and ST Micro-electronics, with support for devices from other manufacturers in the pipeline. No configuration files are required; Maven auto-detects SoC parameters such as CPU core type, on-chip memory map and debug features. Maven also incorporates support for programming Flash memory on all supported SoCs, again without the need for configuration files on the host.
Included with the board are two ribbon cables (0.1" and 0.05") with IDC headers, and a transition "paddle" board for connecting Maven to the target ARM board. Note that a USB-A to USB-Mini-B cable is not supplied. The USB cable is normally only required to provide power to Maven if your target's power supply doesn't meet Maven's requirements.
