K60FN1M TWR - ;Demo Lab' hangs in mcg.c

rcl-arm-coder — Tue, 23 Dec 2014 10:03:32 GMT

Hangs up here:

while (MCG_S & MCG_S_IREFST_MASK){}; // wait for Reference clock Status bit to clear

Tried all J9/J6 combinations, still halts there.

I am reasonably sure, this being only my second board from Freescale Kinetis Tower series, that I am NOT THE ONLY ONE

this has happened to, and that Freescale is aware, has a solution etc etc etc.

While I see the humour in this, the management here fails to see the funny side of two 'Highly integrated' 'Out of the Box' functional

kits to 'speed our time to market' that prove to be bug ridden disasters.

I would have thought the safest way forward would be to use the on board xtal etc - not so!

calling info

#define K60_CLK	1
#define REF_CLK	XTAL8 /* value isn't used, but we still need something defined */
#define CORE_CLK_MHZ	PLL96	/* 96MHz is only freq tested for a clock input*/

See page 9 of http://www.utasker.com/docs/KINETIS/uTaskerV1.4_Kinetis_demo.pdf

for clocking/jumper settings.

If you work with Ethernet you need to use the 50MHz source from the TWR_SER board.

for binaries that you can use to check the operation, including KBOOT compatible USB-HID and UART loading with USB-MSD composite capability in parallel.

Hi Richard Lowes,

What is the part number of your demo board, TWR-K60DN512 or TWR-K60D100M?

And which demo project are you running?
