Other Parts Discussed in Thread: TMS570LS3137

Hi,all

I use the code in "NoRTOS_CCS_RM46" project ,and I find something inconvenient.After I programming the TMS570LS3137 ,then turn on power, the program dosn't run ,I use CCS V5.2 connecting TMS570LS3137,and the program stop at asm(“ b #-8”) ,then I add 4 to PC register, then the program run .

The problem is in normal use , no one can do the operation described above.How to use TPS65381 easily?

Hope to get answer soon. Thanks a lot.

If you comment that line and rebuild it, it should run. Can you describe "don'trun at all" in detail.

Thanks,

The code stop at while((spiREG2->FLG & 0x100)!=0x100);

if I don't delete asm(“ b #-8”) ,I turn off the power,then turn on the power,connect CCS ,then the code will stop at asm(“ b #-8”) ,then add 4 to PC ,the code will run .

If there is no asm(“ b #-8”) ,then the code will stop at while((spiREG2->FLG & 0x100)!=0x100);
