[参考译文] Linux/DRA746：PCIe 无线卡初始化时出现不稳定错误

尊敬的 Francesco Valla：

观察到错误时链路的状态是什么。 可以通过读取 PCIECTRL_TI_CONF_DEVICE_CMD 寄存器(0x51002104)来获取状态。

要检查的另一件事是 Broadcom BCM4359卡本身是否已损坏？

另一件事是确定复制固件的确切故障位置、如果是在开始还是在一段时间后？ 为此、请在 drivers/net/wireless/Broadcom/brcm80211/brcmfmac/pcie．c 中添加调试打印 根据您的描述，问题可能出现在 brcmf_PCIe_download_fw_NVRAM()中。 因此，在 brcmf_PCIe_download_fw_NVRAM()中添加调试打印并共享您的观察结果。

谢谢
Kishon

您好！

链路状态为 L0：PCIECTRL_TI_CONF_DEVICE_CMD 寄存器(0x51002104)= 0x00000045

从我可以看到的内容来看、错误似乎在固件复制之前就出现了、而此阶段的故障是由这些错误导致的。

您好！

好的、链路正常。

在上面的中、第一个"brcmf_chip_ai_resetcore"是从 brcmf_chip_cr4_set_passive 输入的。 谁 第二次调用 brcmf_chip_resetcore？ 第二次写入 BCMA_RESET_CTL 后、问题似乎会发生。

您好！
此外、从 brcmf_chip_cr4_set_passive 调用第二个 brcmf_chip_resetcore、tht 会再次运行。

调用顺序为：

brcmf_chip_recognition -> brcmf_chip_set_passive -> brcmf_chip_cr4_set_passive -> brcmf_chip_resetcore
