在Trigger Mode一节中提到了要定义主机应用程序在Trigger Mode下需要遵循几步,第一步就是定义host IRQ。请问定义host IRQ as the host wake up source要参考哪里? Kevin Qiu1: 用的哪款产品,哪个例程?你说的host IRQ as the host wake up source是哪份文档中的,具体说明下 user6464274: 回复Kevin Qiu1: cc...
Then based on a pre-defined criteria (say a matching advertisement) encountered during the suspend the module will toggle its BT host wake pin so that Linux can be woken up by an IRQ. This is what Laird have to say about it : https://www.lairdconnect.com/support/faqs/are-signals-bt...
The interrupt handler sdio_oob_irq_handler( void* arg ) would cause the host MCU to exit powersave mode and wake up. I have enquired internally to find out if there are any other settings that are required to enable OOB. Alternately you can use WOWL to wake up the host MCU using WL...

host->mmc->pm_caps |= MMC_PM_WAKE_SDIO_IRQ; } } 3、sdhci_pltfm_register 使用得比较少,简单了解下即可。 intsdhci_pltfm_register(structplatform_device *pdev,conststructsdhci_pltfm_data *pdata){structsdhci_host*host;intret =0;/* 调用sdhci_pltfm_init分配并初始化一个sdhci_host */host =sdh...
sdhci的中断号(sdhci_host->irq) 因此,sdhci-pltfm实现了两个方法来统一设置这些信息,方便host driver对于sdhci driver的使用。 2. 数据结构说明 2.1 struct sdhci_pltfm_data struct sdhci_pltfm_data { const struct sdhci_ops *ops; unsigned int quirks; unsigned int quirks2; }; 首先看一下sdhci-pltfm要...
4) R27 controls the peripheral/host mode and the SEPIRQ bit. 5) When [GPXB:GPXA] = [1:0] and the bit SEPIRQ = 1 (R27 bit 4), the GPX output replaces the BUSACT signal with a second IRQ pin dedicated to the GPIN pin interrupts. Table 2. MAX3421E Register Map in Host ...
