[参考译文] TDA4AL-Q1：SDK0806 中的 GPIO_socConfigIntrPath init 失败

尊敬的  Xingyu：

谁是客户？

他们找到了 GPIO API：默认 PDK init 中的 gpio_socConfigIntrPath 将失败。

此外、该函数返回什么错误？

谢谢、

Neehar

你好 Neehar、
   Sciclient_rmIrqSet() 返回–1、其参数如下：
      

rmIrqReq.src_id           = TISCI_DEV_GPIO0;
rmIrqReq.src_index        = 0;  
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_ID_VALID;
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_HOST_IRQ_VALID;

rmIrqReq.dst_id       = TISCI_DEV_R5FSS0_CORE0;
rmIrqReq.dst_host_irq = 396;

您好、Zhao、

感谢您提供此信息。 我将进一步研究这一点、然后返回给您。

谢谢、

Neehar

嗨、Neehar、
   是否有关于此问题的任何更新？
谢谢
Zhao Li

您好、Zhao、

您是否在为任何内核上的所有 GPIO 配置中断路径时遇到问题？ 或者、问题是否仅发生在 MCU2_0 上的 GPIO0_0 上？

谢谢、

Neehar

嗨、Neehar、
  我尝试了 GPIO0_17、GPIO0_28 和  GPIO0_34、 但都未能配置 中断路径。  。、gpio_read () 可以得到正确的 0、1、1 μ s

您好、

除 MCU2_0 之外的任何其他内核上是否存在相同的问题？

感谢您提供详细的日志、我将更深入地介绍它。

谢谢、

您好、Zhao、

我正在研究它,并将在几天内回到你。

嗨、Neehar、
   我在内核、中尝试了 GPIO0_0 手动将 GPIO 的方向更改为输入后、可以触发中断。

   这是测试代码

	pinctrl-single,pins = <
		J721S2_IOPAD(0x0, PIN_INPUT, 7) /* (AC18) EXTINTn.GPIO0_0 */
	>;
 };
 
 fsync-gpios = <&main_gpio0 0 GPIO_ACTIVE_HIGH>;
 

interrupt code：
static inline irqreturn_t sync_handler(int irq, void *id)
{
    struct timespec64 ts;
    ktime_get_ts64(&ts);
    pr_info("ktime_get_ts64(): %lld.%09ld\n", (long long)ts.tv_sec, ts.tv_nsec);
    return IRQ_HANDLED;
}

static int gpio_irq_init(struct device_node *node)
{
	int ret;
    int fsync_irq;
	int fsync_gpio;
	
    fsync_gpio = of_get_named_gpio(node, "fsync-gpios", 0);

    if (!gpio_is_valid(fsync_gpio))
        return -EINVAL;

    if (gpio_request(fsync_gpio, "gpio_label") < 0)
    {
        pr_err("Fail to request GPIO %d\n", fsync_gpio);
        return -EINVAL;
    }
    
    gpio_direction_input(fsync_gpio);

	fsync_irq = gpio_to_irq(fsync_gpio);
    ret = request_irq(fsync_irq, sync_camera_handler, IRQF_TRIGGER_RISING, "GPIO_FSYNC", NULL); 
    if (ret < 0)
    {
        pr_err("request fsync irq error ret:%d\n", ret);
        gpio_free(fsync_gpio);
        return -EINVAL;
    }

    pr_info("Success register fsync irq %d\n", fsync_irq);
    return 0;
} 

    
   当 GPIO0_0 值从 0 变为 1 时、没有中断

您好、Zhao、

您是否对 sciclient_defaultBoardcfg_rm.c 进行了任何更改？

该文件可在以下位置找到：  [pdk_install_path]/packages/ti/drv/sciclient、soc Boardcfg/V4/sciclient_defaultBoardcfg_rm.c

谢谢、

Neehar

嗨、Neehar、
  我已检查了 git repo、没有关于  sciclient_defaultBoardcfg_rm.c 的更改历史记录、这与原始封装 ti-processor-sdk-rtos-j721s2-evm-08_06_01_03 中的历史记录一致

谢谢
Zhao Li

您好、Zhao、

    MCU2_0 的输出日志如下：

在这种情况下、sciclient 调用的值是正确的。 我正在更深入地研究为什么 sciclient 呼叫失败。

MCU2_0 的输出日志如下：

所有三个 WKUP_GPIO 引脚的闪烁调用的值也正确。 但是、从 WKUP_GPIOMUX_INTR 分配的中断线路只有 2 条。 因此、除非您为内核分配更多线路、否则您将无法为所有三个引脚注册中断。

谢谢、

Neehar

尊敬的 Neerhar：
   非常感谢！ 我将尝试这个补丁并在稍后提供反馈。

谢谢
Zhao Li

您好、Zhao、

我 将等待您的测试和反馈。

谢谢、

Neehar

尊敬的  Neerhar：
  此修补程序不适用于我的 case、   Sciclient_rmIrqSet () 像以前一样返回–1。
  可能在我们的 sciclient boardcfg 中存在一些错误配置、我将深入探究这些错误。
  感谢您的帮助！ 此票证可以关闭。

谢谢
Zhao Li

您好、Zhao、

如有任何疑问或问题、欢迎随时跟进。
