Re: [U-Boot] [PATCH 1/1 RESEND] NET: Fix system hanging if NET device is not installed

If we try to boot from NET device, NetInitLoop in net.c will be invoked. If NET device is not installed, eth_get_dev() function will return eth_current value, which is NULL. When NetInitLoop is called, "eth_get_dev->enetaddr" will access restricted memory area and therefore cause hanging. This issue is found on Tegra30 Cardhu platform after adding CONFIG_CMD_NET and CONFIG_CMD_DHCP in config header file.

Oh, you didn't send this patch to anyone, just the mailing list. I added the net maintainer to Cc so he'll see this patch.

BTW, this is a critical bugfix, to avoid hangs without any USB Ethernet device attached.
