Hi Mark
I saw that sometimes when some file is open, and device has been reseted, after that , this file is full of '.' and the size of this file is about 0.5 Mb.
I am wondering, is there any procedure in uTasker to erase all internal Flash memory?

Luminary Micro ^TM LM3SXXXX / JTAG as GPIO problem

« on: April 30, 2010, 07:26:46 PM »

Hello, i've got small problem, can't set JTAG as GPIO
my def are:
#define J1_PORT_BIT    PORTC_BIT0
#define J1_PORT    GPIODATA_C
#define J1_DDR    GPIODIR_C
#define ENABLE_J1_PORT()    GPIODEN_C |= J1_PORT_BIT;
#define J1_JTAG_TO_GPIO    GPIOAFSEL_C |= ~(J1_PORT_BIT);
#define J1_OUTPUT    J1_DDR |= (J1_PORT_BIT);
#define J1_INPUT    J1_DDR &= ~ (J1_PORT_BIT);
#define J1_ONE    J1_PORT |= (J1_PORT_BIT);
#define J1_ZERO    J1_PORT &= ~ (J1_PORT_BIT);

and 10s after start:
J1_JTAG_TO_GPIO;
ENABLE_J1_PORT();
J1_OUTPUT;
J1_ZERO;

SO PORTC_BIT0 should be 0 but is 1, any help?

I am wondering why just sometimes like once in a month my board just stop working and status led stop toogle. Watchdog doesn't react. The status led stays turned on or of. Where can i look for reasons of this behaviour? Ofcourse watchdog is turned on.
