KDS 3.2 TAD BUG using MQX - NullPointerException

thiagow — Mon, 29 Aug 2016 19:34:04 GMT

I did the migration from kds2.0 to kds3.2 and have problems to debug my MQX 4.1.1 application using the MQX TAD plugin to see the stack sizes, tasks, etc.

It's impossible to debug and using the TAD , because this plugins have a bug and show a NullPointerException using TAD log:

When I click in "About MQX RTOS TAD" no windows is displayed

My problem is equal of this already opened topic: MQX Kernel Log window is empty

My MQX is : 4.1.1

My KDS is: 3.2

My OS: Ubuntu 12.04 64 bits

I did all KDS3.2 updates and installed MQX TAD. The installed is: MQX RTOS Task Aware Debugger for GDB 1.0.9.201508111009 com.freescale.mqx.gdb.tad.eclipse.feature.group Freescale Semiconductor, Inc.

My board is: frdm-k64f

My flash device is: Multilink Universal

I already compiled bsp, psp, rtcs and my project with debug ( gcc -pg) and without optimization (gcc -O0) and set #define MQX_KERNEL_LOGGING 1 and #define MQX_ENABLE_LOGS 1 but the TAD doesn't work. I already applied this patch in mqx.c but without result:

I already enabled the kernel log in user_config.h, but don't have success:

/* DESABILITAR EM RELEASE */
#define MQX_KERNEL_LOGGING 1
#define MQX_USE_LOGS 1

Does anybody have any idea?

Hi Thiagrow:

My PC (OS is Win7) is installed with KDS3.2 and MQX 4.2, it can work well. Have you tried if your KDS3.2 can work with your MQX 4.2 application in your side?

Regards

Daniel
