so added earlycon to the bootargs, enabled earlycon in kernel config, and set CONFIG_CMDLINE_FORCE=y in .config.set and .config.target. Am I still missing something?

still stuck at, thanks for your patience with me:

Did you also set the actual command line in CONFIG_CMDLINE? Use the line from the dts bootargs entry.

Just use kernel_menuconfig - boot options and set both options.

Update:

BTW is your dts node "blsp1_uart1" actually enabled?

That needs to enabled to get serial output from the kernel

Like that:

thanks a lot Kirdes, made some progress in the meantime. Am able to initiate the boot sequence now.. next, troubleshooting and trying to get all device nodes in the DT properly working.

update:
OpenWRT with kernel 6.1.55 boots with working uart, gcc, pinctrl, spi, i2c, mdio0/mdio1, remoteproc (q6v5), tsens, pcie phy x1. x2 doesn't come up for some reason although regs are the same with a different base/lane offset.

any pointers on how to initialize the switches (ipq5018 and qca8337) properly and on the issue with the x2 pcie phy?

the qpic nand controller lacks an upstream driver, but I'll give this rejected patch a go, though not having any high hopes.

Is the x2 pcie even connected to something?

You should first fix the reserved memory overlap warnings.

For ethernet/switch support you need the OpenWrt qca-ssdk and qca-nss-dp packages, and a lot of dts nodes (mdio, ess-switch, dp etc.)
Example from the ipq-5.4 downstream kernel

Please note, OpenWrt qca-ssdk and qca-nss-dp packages doesn't have ipq50xx support ad the moment, that needs to be added to the Makefiles as well.

Look in the the Makefiles from qsdk how to properly add the ipq50xx config

26

x2 works for me on Motorola Q14, did you set the PERST GPIO?

27

thanks both, was a bit busy, but managed to work on it again today. Solved the overlapping memory issues, got the QPIC serial nand controller working, PCIE x2 does come up, disabled PCIE x1 as it's disabled in stock FW too. I'm now stuck at initialising the switches as I'm unable to compile the QCA SSDK: Compile error on QCA SSDK - For Developers - OpenWrt Forum

@robimarko: have you been able to compile it with ipq5018 as a target? Have tried with both Debian and Ubuntu.
any pointers you or anyone else can give?

next: get the switches working (ipq5018 and qca8337 and figure out how they're connected exactly) + ath11k for ipq5018 and ipq6122.

@kirdes: to reply to your Q about whether something's connected to PCIE, in the mx5500 (slightly different version than the mx2000), I believe QCN9024 is connected.

been wrestling with ssdk today to try and bring up the switches (ipq50xx + qca83xx) and would kindly request an extra pair of eyes pls:

stock dts specifies gpio39 as the 'phy-reset-gpio'. When I specify reset-gpios under the mdio in openwrt, it doesn't properly reset and causes ssdk initialization of the second switch - qca83xx - to fail as the mdio bus it's connected to reports the mdio device is missing:

tested LAN and WAN ports by connecting and changing a cable

dts file: ipq5018-mx2000.dts

stock dts: snippet from stock dts (mx2000) let me know if you need the whole dts

How would I proceed and initialize and connect the two switches properly? I'd assume the reset gpios are required?

29

According to https://git.codelinaro.org/clo/qsdk/oss/kernel/linux-ipq-5.4/-/blob/NHSS.QSDK.12.4.r1/arch/arm64/boot/dts/qcom/ipq5018-mp03.1.dts

There are two different reset gpios.

In the mdio1 node its gpio 39, but in the switch1 node it's gpio27. You have the same gpio 39 in both the mdio1 and switch1 node.

BTW the correct syntax would be: <&tlmm 39 GPIO_ACTIVE_LOW>;

30

Thanks for the quick response, will try it tomorrow morning. I actually thought about this earlier and figured that 0x27 hex is 39 which made me think it couldn’t be a coincidence. Will try nonetheless and update the thread.

Other Q: how would one go about setting up ethernet devices and assign labels for wan and lan1/lan2/lan3 in this configuration having 2 switches?

31

Yes you are right, it's 0x27 in the switch node. So it's working if you only use the reset_gpio property at the switch node?

I've no experience with ipq50xx, my best guess is, this is just one switch with 2 different dts nodes to configure the cpu-port and the other node for the actual switch ports from the external switch.

For me it looks like it's a AR8337 compatible switch connected the the uniphy-port of the ipq50xx.

May be @robimarko can shed some light.

32

AFAIK, IPQ50xx has no built-in switch so it has to be external.

If it is QCA8337 then qca8k can be used for the switch instead of SSDK

33

At least the switch1 node looks like AR8337

But I guess ssdk ist still needed to configure the uniphy port?

34

Yes, UNIPHY needs to be configured by SSDK, I doubt it will be as simple as adding qca8k node.

35

so I think I've made 'some progress', the external switch (qca8337) resets properly by setting the reset gpio in the switch node as:

reset_gpio = <&tlmm 39 GPIO_ACTIVE_LOW>;

While digging into the SSDK source, I found the correct property name while it's iterating through the port nodes defined in the switch node:

for_each_available_child_of_node(phy_info_node, port_node) {
		if (of_property_read_u32(port_node, "port_id", &port_id))
			return SW_BAD_VALUE;
		if (!cfg->port_cfg.wan_bmp) {
			cfg->port_cfg.wan_bmp = BIT(port_id);
		} else {
			cfg->port_cfg.lan_bmp |= BIT(port_id);
		}

		/* initialize phy_addr in case of undefined dts field */
		mdio_node = of_parse_phandle(port_node, "mdiobus", 0);
		if (mdio_node)
		{
			ssdk_miibus_add(dev_id, of_mdio_find_bus(mdio_node), &miibus_index);
			phy_reset_gpio = of_get_named_gpio(mdio_node, "phy-reset-gpio",
				SSDK_PHY_RESET_GPIO_INDEX);
			if(phy_reset_gpio > 0)
			{
				hsl_port_phy_reset_gpio_set(dev_id, port_id,
					(a_uint32_t)phy_reset_gpio);
			}
		}

so I renamed the property in the mdio node from reset-gpios to phy-reset-pgio:

phy-reset-pgio = <&tlmm 39 GPIO_ACTIVE_LOW>;

The two switches initialize correctly now:

I can now see the phy status changing on mdio1 (connected to the qca8337 switch) between UP/DOWN when connecting a UTP cable in the different external ports so the reset is working.

root@OpenWrt:/# mdio 9*            (<-- mdio1 bus)
 DEV      PHY-ID  LINK
0x00  0x004dd036  down           //GE Phy I suppose?
0x01  0x004dd036  up             //WAN
0x02  0x004dd036  down           //LAN1
0x03  0x004dd036  down           //LAN2
0x04  0x004dd036  down           //LAN3

qca8337 switch ports are configured as follows (as per stock DTS):

switch_cpu_bmp = <0x40>;  	/* cpu port bitmap: port 6 */
switch_lan_bmp = <0x38>; 	/* lan port bitmap: port 3 4 5 */
switch_wan_bmp = <0x04>;  	/* wan port bitmap: port 2 */

Problem I have now is that the GE Phy connecting the 2 switches doesn't come up on either of the mdio buses. The phy correctly is successfully probed though based on above logs.
Any ideas?

updated DTS: ipq5018-mx2000.dts

think I know what's going on, as @kirdes pointed out, qca-nss-dp fails to compile. I suspect in previous compilations it used the already compiled version of qca-nss-dp before switching target to MP for ipq50xx so the dp (MAC1 on ipq5018 switch) never initializes and stays down..

compiler chokes on: Compile error on QCA SSDK - #14 by georgem83

37

both qca-ssdk and qca-nss-dp compile now and I'm able to initialize the 2 switches + dp.
I can ping eth0 from the terminal, but pinging other devices fails.

I've setup the config of the switches and mdio buses as defined in the stock dts, but that doesn't work.

eth0 comes up, but I probably am not configuring it right.

this is how the output of swconfig and ipconfig in stock (removed lines for brevity):

what command do I use in openwrt to check status of the ports? (after moving away from swconfig)

I suppose I have to use ucidef_add_switch or a similar command in the 02_network file?
if so, can you tell me what and how?

38

There is no way to look into port status for the switch drivers provided by SSDK other than swconfig, however if you want to enable it then you must add stuff from QSDK that OpenWrt doesn't support in its swconfig.

Proper solution would be to run away from SSDK for the switch support, if its just QC8337 then you can use qca8k for it.

39

another of this kind of configuration... did qcom suggest this by design if device needs extra port? o.O

40

the router contains two switches:
1: 2-port ipq50xx in the soc itself
2: qca8337

AFAIK ipq50xx GMAC0/phy7 is connected over MDIO to phy0/MAC1 on qca8337
the SSDK is needed for at least the first switch

On qca8337, based on the LAN/WAN bitmap:
MAC2/phy1 -> WAN
MAC3/phy2 -> LAN1
MAC4/phy3 -> LAN2
MAC5/phy4 -> LAN3
MAC6 -> CPU (SGMII)
