Tool/software:
Hi Expert
Customer feedback an issue with F28069 LP, they use the SDK demo Example_2806xGPIOToggle, the modifications are below, the jumper are MUX_SEL(0) CH_SEL(1):
Step 1: Set GPIO15:
GpioCtrlRegs.GPAPUD.bit.GPIO15 = 1;
GpioCtrlRegs.GPAMUX1.bit.GPIO15 = 0;
GpioCtrlRegs.GPADIR.bit.GPIO15 = 1;
GpioCtrlRegs.GPACLEAR.bit.GPIO15 = 1;
Step 2: Add GPIO toggle in Gpio_example3:
for(;;)
{
GpioDataRegs.GPATOGGLE.all = 0xCFFF FFFF;
GpioDataRegs.GPBTOGGLE.all = 0x0000 000F;
delay_loop();
GpioDataRegs.GPATOGGLE.bit.GPIO15 = 1;
}
but you can see the scope, there is only ~200mV when the gpio is pulled up in the code.
Could you please try this on the LP to see whether you can reproduce the issue and how to solve?
Thanks
Joe
