I tried to run the demo code from FSL (D:\Freescale\Kinetis L Sample Code\kl25_sc_rev5\klxx-sc-baremetal\build\iar\vlpr_lls_adc). The RGB LED should be toggled based upon counter of LPTMR timebase.
However LED array doesn't change at all. The hardware is all right, since the FRDM_KL25ZDemo works fine. The only differences between these demo applications is : vlpr_lls_adc uses GPIO to toggle LED, while FRDM_KL25ZDemo uses TPM to drive RGB LEDs.
Does anyone knows why?
