Freemaster with K20 72MHz

abidesmail — Tue, 27 Jan 2015 04:02:01 GMT

Hi,

I setup freemaster via UART1 on a K20 72MHz processor and it's awesome. I followed the following tutorial:

http://mcuoneclipse.com/2013/08/24/tutorial-freemaster-visualization-and-run-time-debugging/

I would now like to try it with JTAG (since I use UART in my application). Is this possible? I currently get the following error when I select JTAG as the device in the FMSTR1 freeMaster component.

Error: This item is not supported by selected CPU.

Not sure if it is not supported or I need to enable some define somewhere. I do have JTAG on this CPU and am using it successfully.

Thanks

Hi,

The problem seems related to the configuration, Attached is a sample on how to set up the configuration. Please refer to the attached file

Hi Fang,

Thanks for getting back to me.

The problem isn't on the Host side, it is on the device side. When I try to select JTAG on processor expert freemaster component I get a message saying ERROR: This item isn't supported by selected CPU. Please see the image below

I also have a related question. I attempted to add the freemaster component on my mqxlite application via UART0 but that did not work either. I added the component as per the link below and then added the following methods to one of my tasks:

void free_master_task(uint32_t task_init_data)

{

int counter = 0;

while(1) {

counter++;

FMSTR1_Poll();

FMSTR1_Recorder();

_time_delay_ticks(10);

/* Write your code here ... */

}

Note: If I create a project that is not an MQX lite project, I able to graph data correctly using freemaster using UART0.

Appreciate the help,

Abid
