Merging NXP LPCXpresso IDE with Freescale Kinetis Design Studio, Processor Expert and Kinetis SDK

So NXP announced here a $40 Billion Merger with Freescale. Frequent readers of my blog will know that I’m using in my own and university projects many Freescale devices with Eclipse based tools (Eclipse Kepler/Luna, Emprog ThunderBench, Atollic TrueSTUDIO, Freescale CodeWarrior and of Freescale Kinetis Design Studio) in combination with Processor Expert. In a few projects I have used NXP devices with the CodeRed Eclipse base tools too. So I was curious how that merger of the two silicon companies could look like, if you merge the Freescale and NXP Eclipse based tools, and mix it with Processor Expert and the Freescale Kinetis SDK? The result looks like this:

Semihosting for Kinetis Design Studio V3.0.0 and GNU ARM Embedded (launchpad)

Freescale has released the v3.0.0 version of the Kinetis Design Studio: this one comes with a great positive change: instead of a custom toolchain, it is coming with the standard GNU ARM Embedded (launchpad) toolchain from ARM. Beside of better code density and less RAM needed, there is one change which affects semihosting. Previously, semihosting was enabled by default in the V2.0.0 libraries. Now semihosting needs to be turned on. This post is how to do this.

Solving “The connected emulator does not support serial wire output (SWO)” for Segger J-Link

SWO (Serial Wire Output) is a cool feature defined by ARM as part of the CoreSight debug block. However, not every debug connection supports SWO, as it requries extra pins routed from the microcontroller to the debug JTAG/SWD header.

If I’m using the Segger J-Link, and if my hardware does not support SWO, I will get a dialog telling me “The connected emulator does not support serial wire output (SWO).”
