From a338c1b71296f1f698b54649160192c42b945b7f Mon Sep 17 00:00:00 2001 From: morris Date: Tue, 4 Dec 2018 17:13:48 +0800 Subject: [PATCH] ethernet: phy init timeout When ethernet enable again after disable it before, phy init will report timeout. The cause of this problem is that the enabling of emac clock is too late, and should be placed before phy init. --- components/ethernet/emac_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/components/ethernet/emac_main.c b/components/ethernet/emac_main.c index d75cd3062..bf8c211c5 100644 --- a/components/ethernet/emac_main.c +++ b/components/ethernet/emac_main.c @@ -809,7 +809,6 @@ static void emac_start(void *param) ESP_LOGD(TAG, "emac start"); cmd->err = EMAC_CMD_OK; - emac_enable_clk(true); if (emac_reset() != ESP_OK) { return; @@ -870,6 +869,7 @@ esp_err_t esp_eth_enable(void) esp_pm_lock_acquire(s_pm_lock); #endif //CONFIG_PM_ENABLE + emac_enable_clk(true); /* init phy device */ if (emac_config.phy_init() != ESP_OK) { ESP_LOGE(TAG, "Initialise PHY device Timeout");
