Part Number: TDA2EXEVM Other Parts Discussed in Thread: SYSCONFIG Tool/software: TI-RTOS hello, i have a same issue in tda2ex, details below: after runing into system, i check the gpio2 reg CM_L4PER_GPIO2_CLKCTRL = 0x00020001 GPIO_SYSCONFIG = 0x1d after i reset gpio2 by set GPIO_SYSCONFIG = 0x1f the GPIO_SYSSTATUS can't Reset completed , the value is always 0x0 the question i want ask is that : why i can't reset gpio2 again but , when i set CM_L4PER_GPIO2_CLKCTRL [8] = 1, it reset ok. can you give me some help?
Responses:
Hi, When CM_L4PER_GPIO2_CLKCTRL = 0x00020001, GPIO is in idle state. Hence you are not able to reset the GPIO. You need to make sure that GPIO2 is fully functional i.e. CM_L4PER_GPIO2_CLKCTRL =0x00000001. Regards, Rishabh
