Booting on 4.14, I have the following message at login prompt.

After boot time i got those message.

as i knew, 4.14 dts doesn’t have pcie nodes. so, pcie is not ready yet.

3

in my repo i added some pcie-nodes (for pcie-slot)…maybe there is any missing for sata…

&pcie {
	pinctrl-names = "default";
	pinctrl-0 = <&pcie_default>;
	status = "okay";

	pcie@0,0 {
		status = "okay";
	};

	pcie@1,0 {
		status = "okay";
	};
};

&pcie0_phy {
	status = "okay";
};

&pcie1_phy {
	status = "okay";
};

It should be unnecessary to being added additional node into data for sata.

it is enough with just enabling obj-$(CONFIG_SATA_AHCI) += ahci.o libahci.o in drivers/ata/Makefile

the sata is just a pci device, it would be matched and called with the appropriate driver when pci-e slot is link up.

5

that line in Makefile in that state and config-option CONFIG_SATA_AHCI is set in my defconfig

what change do you mention?

6

No, your setup should be enough and correct. There should be other causes making the timeout.

7

@xbgmsharp can you please build debug-branch from my kernel and test again?

added pcie-patch from lede, maybe this fixes your sata-issue

@linkerosa you can also use the debug-branch for pwm :slight_smile:

8

I boot with the debug-branch however no message appears.

9

sounds good…can you access your sata-drive?

have you last version of debug-branch (with BT)? hen you can test this also :wink:

10

I do have the latest version with BT on 4.14.11

please first stay on sata…is that working?

this is my net-message:

[   12.400201] mt7530 mdio-bus:00 lan0: Link is Up - 1Gbps/Full - flow control off

for bluetooth…intialisation seems to be initialized without errors…have you found anywhere errors?

gary is working on audio currently for 4.4…if that works i can try to port it (if not already in 4.14)…i have audio not enabled…maybe you find an option to get it working

please note that i’m a private person and not professional developer which is doing that in free-time :slight_smile:

No worries me too.

I am just checking what is the status of the board.

In term of sata no more message. i will keep an eye on it.

13

Currently i want to get the router-specific functions (ethernet/gmac,hnat,wifi,vlan,…) working first. i that is working, i try to go further :slight_smile: any help is welcome,also on other functions.

do you got any errors on bt? Can you access your sata-drive?

14

SATA-access successful? can your read/write without erros to your disk attached on sata?

(i want to merge the debug-branch)

15

Yes no more error, i able to access read/write to the disk.

16

You can merge the vlan_414 and debug in the main branch.

17

for vlan_414 i will do additional tests…but must configure my equipment…good to know it is working so far…

can you try hnat?

debug merged to main…

18

Did not figure out how to test/sue hnat yet i use classic iptable.

19

me too :slight_smile: i assume that the throughput will be higher throught NAT with HW-acceleration

i also want to define the nat in iptables, but accelerated by SOC
