Hello Warren: I have confirmed in code that I re-assign SCL0 pin after SSP has called this function: ssp_err_g_sf_touch_panel_i2c = g_sf_touch_panel_i2c.p_api- open (g_sf_touch_panel_i2c.p_ctrl, g_sf_touch_panel_i2c.p_cfg); We need to find out if SSP re-configures hardware in any other routine except the one above or if they call this open function ever again in SSP. Thanks for your help.
