Hi, > But you need an unbrended jLink. this is not the whole truth, µVision supports all JLinks that are not "bounded" to an IDE, i.e. the yellow IAR ones. You may use: - JLink, JTrace for ARM7/9, Cortex-M (black Boxes) - SAM-ICE (blue Atmel Boxes) - midas-Link (ADI) - on Board JLinks (i.e. µCrium, EnergyMicro) - ... > I think the Keil MDK is completely supported. It's the other way around The µVision Cortex-Driver for JLink covers (nearly?) all of JLinks capabillities (also special things like …

Hi, > Since Keil seems not to support this feature, µVision _does_ support that, via Command Window. Enter: > BS read myVar; > BS readwrite myVar; > BS write myVar; > BS read myVar == 0x55; The Cortex-M Architecture allows you to set up to 4 Watches. This can be watches for the Logic Analyzer, Breakpoints etc. Complex Watches (i.e. BS read myVar4 == 0x55; ) take two of the 4 avaiable WP Units. BR, /th.

Hi, if you are using a Cortex-M3 device and CMSIS, you can easily use the ITM_Sendchar(c) function, defined in CMSIS core_cm3.h. The ITM output (channel 0 for printf) is captured from the J-Link through SWO sampling, this must be configured (dependant on your IDE). On ARM7/9 there is a method called semihosting, a printf is redirected through armlib to the debugger, how this works with J-Link the Segger guys should be able to help In Keil uVision on ARM7/9 and there is the Real Time Agent doing …
