Cannot debug internal RAM DS-5 Vybrid projects. External RAM works.

rocketdawg — Thu, 24 Jul 2014 18:32:17 GMT

using 4.1.0.1

DS-5 5.19

using TWR-VF65GS10 dev board

I can build hello world or other projects and choose internal RAM or external RAM debug

external RAM works

internal RAM gives error something like this.

Stopping running target Freescale - Vybrid VF6xx on TCP:localhost on connection

found the issue.

looks like this does not work for DS-5 so I commented out the #error

#if __IAR_SYSTEMS_ICC__

#pragma section = "KERNEL_DATA"

#define BSP_DEFAULT_START_OF_KERNEL_MEMORY ((void *)__sfb("KERNEL_DATA"))

#elif defined(__CC_ARM)

#define BSP_DEFAULT_START_OF_KERNEL_MEMORY ((void *)__KERNEL_DATA_START)

#elif defined(__GNUC__)

#define BSP_DEFAULT_START_OF_KERNEL_MEMORY ((void *)__KERNEL_DATA_START)

#else

//#error UNKNOWN COMPILER - IMPLEMENT ME!!!

#define BSP_DEFAULT_START_OF_KERNEL_MEMORY ((void *)__KERNEL_DATA_START)

#endif

Thanks

I think that separate documents for different tools/dev kits is a better way to go.

I hope these make their way into the next release.

The topics are similar in the "one size fits all" "Getting Started with Freescale MQX™ RTOS Rev. 15" document in the ./docs directory.

One thing I noticed is, section 3.1 the second screen shot is not what I see in DS-5.19

the "Bare Metal Debug" only has entries for A5 or M4 and the "Target Connection" is a dialog box that selects CMSIS-DAT, ULINK Pro, ULINKPro D. interesting, no DSTREAM.

you might want to update that screen shot

this document is missing all the content about the twrvf65gs10 jumper selections for USB and the serial port found in

Getting Started with Freescale MQX™ RTOS Rev. 15 section 8.1.2

If this information is to be elsewhere, then it would be nice to have a link or reference to point to.

I have not yet got the uart to work.
