If you have an issue to run MQX + FNET Bootloader on Lasco.
You should aply workaround to MQX code (otherwise it goes to infinite “while” )
/Special thanks to Amly/
bsp_init.c (for mcf51cn platform):
static void _mqx_clock_init_25MHz()
{
...............................................
#if 0
//b) Loop until OSCINIT (bit 1) in MCGSC is 1, indicating the crystal selected by the EREFS bit
//has been initialized.
while (!(reg_ptr->MCG.MCGSC & MCF51XX_MCGSC_OSCINIT_MASK))
;
#endif
...............................................
#if 0
// wait for Reference Status bit to update
while (!(reg_ptr->MCG.MCGSC & MCF51XX_MCGSC_IREFST_MASK))
;
#endif
...............................................
}
Hope it be fixed in the future version of MQX.
Also the standard modifications that are valid for all platforms:
1. user_config.h
#define MQX_ROM_VECTORS 0
2. intflash_FNET.lcf
