EFM32 Development Kit
The EFM32 Development Kit features the EFM32G890F128 MCU (128 kB flash + 16 kB RAM) and is one of the best kits designed for low power device development.
The Advanced Energy Monitoring (AEM) system is practically a very good power monitor and logger, embedded in the Development Kit. Some other kits are doing this in the IDE, but to have it with a display onboard is awesome.
A large spectrum of techniques, from using different low power modes to switch-off peripherals can be tested directly and all with one kit.
The on-board Segger J-Link enables debugging.
The OOB configuration enables that the EFM32 can be programmed with many demo programs selected with the 320×240 TFT Display GUI and the power consumption can be monitored on the same TFT after programming.

Sometimes the Mighty BeagleBone may ask for a new, unknown driver named SUBARCTIC. His VID is 0451 and PID is 6141, at least in the case of a A6a board.
A simple search about this can lead to a bunch of different opinions but the truth seems to be that is appears only in Sitara’s bootloader mode, when he waits for some other debugging options, maybe something on the non-soldered P7 JTAG Connector.
The BeagleBone Subarctic QuickFix
So, BeagleBone is built to boot something from the SD Card… Inserting the Linux SD Card all works fine, the board get into linux boot sequence, the right devices (USB Serial Port, RNDIS Gadget… ) are showing up and the drivers are loading.
The quick fix: don’t search for a driver instead put the SD Card with software in the connector and cycle power.
Here is a USBView capture of the SUBARCTIC issue:

Some TI Sitara JTAG advices:
LPC800 series develeopment tool
It’s amazing. Simple and efficient.
The small pin number is compensated in a great way: The Switch Matrix – it connects 6 pins to any available internal module.
Of course, programming can be done in bootloader mode, where every pin is reassigned according to the original layout.
- ARM Cortex-M0+
- Switch matrix for flexible configuration of each I/O pin function
- 2 USART interfaces, 1 SPI controller and 1 I²C-bus, with pin functions assigned through the switch matrix
- Self Wake-up Timer (WKT) clocked from either the IRC or a low-power, low-frequency internal oscillator
- CRC engine
- Boot ROM API support: boot loader, USART and I²C drivers in ROM, power profiles, Flash In-Application Programming (IAP) and In-System Programming (ISP)
The debugging options supported are SWD (10 pin connector), JTAG boundary scan and Micro Trace Buffer (MTB).
The quickest/cheapest programming method is via
spi*ISP (6 pin connector) with a USB/Serial cable.

Great! But I’m still waiting for the new tideals site…
The Stellaris Launchpad – a good and cheap ARM tool.
The pre-registered Stellaris Launchpad version was 4.5USD only, actual version is 12.99 USD.
This fantastic board features two LX4F120H5QR (ARM Cortex M4 with floating point), one as ICD and one as target, two user switches and one RGB Led driven by 3 transistors.
The “target” clock oscillator is build with Y1 32k768 and Y2 16MHz Osc.
The power jumper allows you to measure the target’s power consumption.
Other great thing is the presence of the two gender stackable headers which allows any header connector/cable combination, the Piccolo C2000 had only dual-side (stackable) male headers.

Testing the C2000 Launchpad:
After loading the default application sourced by TI Control Suite 3.0.3 into TI Code Composer 5 I changed the “Celcius” spelling into “Celsius”. May be someone’s trademark?
The C2000 Launchpad works great, the XDS100 included is instantly detected by the Code Composer and works as debugger in the same time with the USB/Serial console.
Another great tool from TI!

Some considerations about debugging with JTAGICE from the User Guide (p.7-8, sections 1.2.2-1.2.6) download User Guide
In Run mode, the code execution is completely independent of the JTAG ICE. The JTAG ICE will continuously poll the target AVR to see if a break condition has occurred. When this happens, the OCD system will read out all necessary data Program Counter, I/O registers, EEPROM, General Purpose registers, and SRAM contents, and transmit this to AVR Studio through the JTAG interface. Since the target AVR device operates independently, there is no way of tracing what code has been executed prior to the breakpoint.
The Stopped Mode: When a breakpoint is reached, the program execution is halted, but all I/O will continue to run as if a breakpoint did not occurred. For example, assume that a USART transmit was initiated when a breakpoint is reached. Using a traditional ICE, the operation would
be halted, and single stepping through the code would give a cycle accurate bit pattern on the TxD pin. When using the JTAG ICE on the AVR, the USART would continue to run at full speed completing the transmission.
Software Breakpoints: A software breakpoint is a break instruction placed in Flash memory. When this instruction is executed, it will break the program execution. When placing a breakpoint on an instruction in AVR Studio, this instruction is physically rewritten as a break instruction in the AVR Flash memory. When reaching this instruction the operation is halted. To continue execution a “start” command has to be given from the OCD logic. When starting the execution, the instruction replaced by software break instruction is executed before continuing to execute instructions from the Flash memory.
Hardware Breakpoints: In the OCD logic there are 4 registers capable of storing one memory address each. The JTAG ICE uses one of these registers permanently to implement single stepping. The 3 others can be combined to generate valid break conditions. Section 3.2.4 describes in
detail the different ways of combining these registers. Software breakpoint require reprogramming of the entire page, hardware breakpoints
are recommended for breakpoints that are often modified.
I/O Registers: JTAG ICE has limitation in viewing the contents in all I/O locations. When an AVR device reaches a breakpoint, the contents of all I/O registers are read out and presented in AVR Studio. Reading alters the contents in some registers, these registers will not be read (e.g., Reading USART data register, will clear the RXC bit). See the “Special Considerations” section to find the complete list of registers that not are
accessible through the JTAG ICE OCD system.
Single Stepping: Some registers needs to be read or written within a specified number of cycles after a control signal is enabled. The I/O clock and peripherals continue to run at full speed in stopped mode, single stepping through such code will not meet the timing requirements. For example, when single stepping, the I/O clock might have run for millions of cycles. To read or write registers with such timing requirements, the read or write sequence should be performed as a single operation. Run the device at full speed by using a macro, function call or run-to-cursor.
