Wlcore, wl18xx firmware seems not loaded

dzhou · September 11, 2020, 12:57pm

Hi Robert,

On my board, only one line of the messages from dmesg | grep wl
[ 2.107412] wlan-en-regulator: disabling
The wl18xx-fw.bin is in the lib folder.
wlcore seems not loaded.
Is the kernel booting message disabled or at higher level? anyway to turn on all messages, including debugging, information, etc.
Any suggestions that why wlan-en-regulartor disabling?

Thank you,
David

That’s actually just noise… (and misleading…)

Dump this instead:

journalctl | grep wl

Hi Robert,

MNU_journalctl_wl.txt (22.7 KB)

Appreciate for your support.

Regards,

David

dzhou · September 11, 2020, 1:50pm

Also,
I found that at U-boot BBBw has
Valid Addresses : 24 34 50 70
And our board only:
Valid chip Addresses: 24 50
that may tell us something.
(Both BBBw and our board loaded with the same version of u-boot)

Best Regards,

David

RobertCNelson · September 11, 2020, 1:51pm

Wow, it’s detected the wl18xx, thus trying to load the module, but wlan0 never comes up… Double check your SDIO bus on the PCB.

dzhou · September 11, 2020, 1:52pm

Hi Robert,

Thank you very much.

Hi Robert,

I am little confused with device tree for mmc’s. Please help me clarify some names: (Please ignore previous posting, miss sent)

from dmesg | grep mmc:
mmc1: new high speed MMC card at address 0001
mmc2: new high speed SDIO card at address 0001
But in dts:

//mmc2 shall be the eMMC
&mmc2 {
	vmmc-supply = <&vmmcsd_fixed>;
	pinctrl-names = "default";
	pinctrl-0 = <&emmc_pins>;
	bus-width = <8>;
	status = "okay";
};

mmc3 is the wlcore, wlan as mmc2 in the dmesg. Am I right?

Thank you,
David

RobertCNelson · September 11, 2020, 6:35pm

Hi @dzhou, the value of “mmc” between the Device Tree and the Kernel is off by one on am335x…

DTS | KERNEL - What it is...
mmc1 | mmc0 - microSD
mmc2 | mmc1 - eMMC
mmc3 | mmc2 - SDIO -WLAN

It’s kinda odd, as on am335x most IP blocks start at “0” (uart/i2c/pwm/etc) whereas the mmc starts at “1”…

Regards,

dzhou · September 11, 2020, 6:37pm

Thank you for your clarification.

So, this is our problem:
mmc2: error -84 whilst initialising SDIO card

David

RobertCNelson · September 11, 2020, 6:41pm

voodoo@hestia:~$ errno 84
EILSEQ 84 Invalid or incomplete multibyte or wide character

Do you have the sdio line’s swapped??

One quick hack, try moving the mmc to “1-bit” mode vs “4-bit” mode…

Change the 4 → 1 like so:

github.com

beagleboard/bb.org-overlays/blob/master/src/arm/BB-BBGW-WL1835-1BIT-00A0.dts#L152


      
          		target = <&mmc3>;
          		__overlay__ {
          			dmas = <&edma_xbar 12 0 1
          				&edma_xbar 13 0 2>;
          			dma-names = "tx", "rx";
          			status = "okay";
          			vmmc-supply = <&wlan_en_reg>;
          			bus-width = <1>;
          			non-removable;
          			cap-power-off-card;
          			ti,needs-special-hs-handling;
          			keep-power-in-suspend;
          			pinctrl-names = "default", "sleep";
          			pinctrl-0 = <&mmc3_pins &wlan_pins>;
          			pinctrl-1 = <&mmc3_pins_sleep &wlan_pins_sleep>;
          
          			#address-cells = <1>;
          			#size-cells = <0>;
          			wlcore: wlcore@2 {
          				compatible = "ti,wl1835";
          				reg = <2>;

Then you only need 3 pins for the bus:

github.com

beagleboard/bb.org-overlays/blob/master/src/arm/BB-BBGW-WL1835-1BIT-00A0.dts#L44-L50


      
          			wl18xx_pins: pinmux_wl18xx_pins {
          				pinctrl-single,pins = <
          					AM33XX_IOPAD(0x878, PIN_OUTPUT_PULLUP | MUX_MODE7)	/* gpmc_ad12.gpio1_28 BT_EN */
          				>;
          			};
          
          			mmc3_pins: pinmux_mmc3_pins {

Careful, those are for the “BeagleBone Green”, here’s the 3 pins on the Black Wireless:

github.com

beagleboard/bb.org-overlays/blob/master/src/arm/BB-BBBW-WL1835-00A0.dts#L72-L74


      
          			AM33XX_PADCONF(AM335X_PIN_MII1_RXD2, PIN_OUTPUT_PULLDOWN, MUX_MODE1)	/* gmii1_rxd2.uart3_txd */
          			AM33XX_PADCONF(AM335X_PIN_MDIO, PIN_INPUT, MUX_MODE3)		/* mdio_data.uart3_ctsn */
          			AM33XX_PADCONF(AM335X_PIN_MDC, PIN_OUTPUT_PULLDOWN, MUX_MODE3)	/* mdio_clk.uart3_rtsn */

We don’t do a one bit hack on the black wireless, as the pin’s are not on the header like the green…

This is assuming, dat0, cmd, clk are in the correct spot on the design…

Regards,

dzhou · September 11, 2020, 6:48pm

From am335x_evm.dts
&mmc3 {
/* these are on the crossbar and are outlined in the
xbar-event-map element */
dmas = <&edma 12 0
&edma 13 0>;
dma-names = “tx”, “rx”;
status = “okay”;
vmmc-supply = <&wlan_en_reg>;
bus-width = <4>;
pinctrl-names = “default”;
pinctrl-0 = <&mmc3_pins &wlan_pins>;

wlcore: wlcore@0 {
compatible = “ti,wl1835”;
reg = <2>;
interrupt-parent = <&gpio3>;
interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
};
};
but-width is 4.
is it possible, change to 1 from 4 without recompiling kernel. Is this exported in the /sys?

PS, can you share your WiFi voltage isolation? (aka 3.3v <-> 1.8v)

BBBW is:

RobertCNelson · September 11, 2020, 6:49pm

You just need to rebuild the *.dtb file, it won’t require full kernel compilation.

Hi Robert,

Well, it has some differences:
mmc3_pins: pinmux_mmc3_pins {
pinctrl-single,pins = <
0x44 (PIN_INPUT_PULLUP | MUX_MODE3) /* gpmc_a1.mmc2_dat0, INPUT_PULLUP | MODE3 /
0x48 (PIN_INPUT_PULLUP | MUX_MODE3) / gpmc_a2.mmc2_dat1, INPUT_PULLUP | MODE3 /
0x4C (PIN_INPUT_PULLUP | MUX_MODE3) / gpmc_a3.mmc2_dat2, INPUT_PULLUP | MODE3 /
0x78 (PIN_INPUT_PULLUP | MUX_MODE3) / gpmc_ben1.mmc2_dat3, INPUT_PULLUP | MODE3 /
0x88 (PIN_INPUT_PULLUP | MUX_MODE3) / gpmc_csn3.mmc2_cmd, INPUT_PULLUP | MODE3 /
0x8C (PIN_INPUT_PULLUP | MUX_MODE3) / gpmc_clk.mmc2_clk, INPUT_PULLUP | MODE3 */
>;
};

MUX_Mode3 for all pins. And pin numbers are not the same as your posting.
There are 4 data bus lines.

Regards,

David

dzhou · September 11, 2020, 7:14pm

Sorry, the am335x_evm.dts file I have may be not the latest. Or to the Buster version. I please ignore my previous post.

Thank you,
David

Hi Robert,

As feedback, our hardware guy figured out that D3 component was not populated on the board, which causes wlcore failed to load.

Regards,
David
