MQX on K70 Tower System issues

cavebiker — Tue, 30 Oct 2012 17:51:11 GMT

I am trying to run some MQX example programs on the K70 Tower System. Using CW10.2 MQX 3.8.1

My problem is, every time I load the example, the code hangs in the __pe_initialize_hardware(void)function on the line of code that checks IREFST in MCG_C6 --> while((MCG_S & MCG_S_IREFST_MASK) != 0x00U)

Has anyone else had this problem and resolved it?

Thank you.

HI cavebiker,

DId you setup the jumpers as described in /doc folder?

Which target are you using?

Have you done updates for CW10.2?

Regards,

DAvid

Hey David,

I will have to re-check the jumpers and compare it to the doc but I thought I had the jumper correct because I'm running bare metal code just fine.

The tower board I have has a pk70fn1m

CW10.2 is updated.

Thanks for the help

Cheers,

Tom

Also make sure you have not plugged the boards the wrong way into the tower. Primary connector must match primary socket!

I think I messed up the project or bsp or someting, but i'm on to CW10.3 MQX4.0 now and all is good.

Thanks much.

Just wanted to let you know that in the hurry I had plugged in the TWR-SER board that actually delivered the clock for my K70 the other way round. The error was the same as you described it.

Ha! that is most likely what I did :|

Thank you

The most crazy thing is that the debugger runs ok and flashes the MCU but the MCU does not run as expected and so the system hangs. I spent a couple of hours figuring out what the problem is and then by accident noticed that the TWR-SER primary was connected to the secondary elevator :-]
