T1进入深度休眠之后，如何让IO口保持高电平输出

[smtlinks]

先设定休眠配置如下
gpio_index_map 0x4000002
gpio_edge_map 0x4000002
gpio_stay_hi_map 0x100
gpio_stay_lo_map 0x200

然后调用void bk_enter_deep_sleep_mode ( PS_DEEP_CTRL_PARAM *deep_param );这个接口进入深度休眠。
此时测量GPIO_8的电平，是0.4V左右。
请问如何设置，能让IO输出高电平。

休眠前用该函数sctrl_set_deep_sleep_gpio_floating_map设置该GPIO状态保持

如果不行，打上如下patch试试：
diff --git a/vendor/T1/T1_os/T1/driver/sys_ctrl/sys_ctrl.c b/vendor/T1/T1_os/T1/driver/sys_ctrl/sys_ctrl.c

• if(((i < BITS_INT)&&(deep_param->gpio_stay_lo_map & (0x01UL << i)))
• if(((i < BITS_INT)&&((deep_param->gpio_stay_lo_map deep_param->gpio_stay_hi_map) & (0x01UL << i)))

  {
  continue;
  }

谢谢。后面这个办法可以解决。
