However, with this processor, we are facing some issues.
Basically, we connected the WILC1000 in SDIO mode to MMC2 interface using the J11 connector on the RICO board (refer to http://www.myirtech.com/download/AM437x/RicoBoard_SCH_V10.pdf ). please note that since the SDIO pull-ups are not available on the Rico board, we added them externally (we used the same 10Kohm value used for the other mmc interface present in the Rico board)
The HW connections are the following:
MMC2_CLK à A12
MMC2_CMD à B12
MMC2_DAT0 à C5
MMC2_DAT1 à C6
MMC2_DAT2 à A4
MMC2_DAT3 à A3
CHIP EN is tied to VCC and the RESET pin is driven by GPIO5_8
The device tree is configured to reflect this in the following way:
&mmc3 {
status = "okay";
dmas = <&edma 30 0>,<&edma 31 0>;
dma-names = "tx", "rx";
vmmc-supply = <&dcdc4>;
bus-width = <4>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&my_configuration_wifi_pin>;
pinctrl-1 = <& my_configuration _wifi_pin_sleep>;
//cap-power-off-card;
//keep-power-in-suspend;
ti,non-removable;
max-frequency = <2000000>;
ti,needs-special-hs-handling;
ti,dual-volt;
cap-sdio-irq;
//disable-wp;
#address-cells = <1>;
#size-cells = <0>;
wilc_sdio@2 {
compatible = "atmel,wilc_sdio";
reg = <2>;
gpio_reset = <&gpio5 8 GPIO_ACTIVE_LOW>;
//gpio_chip_en = <&gpio0 12 GPIO_ACTIVE_HIGH>;
//gpio_irq = <&gpio0 13 GPIO_ACTIVE_HIGH>;
};
};
The IRQ line is commented since it is not actually used by WILC1000: when compiling the wilc1000 driver, we chose to use the in-bound interrupt of the SDIO interface;
The pins are defined as the following:
my_configuration _wifi_pin: my_configuration_wifi_pin {
pinctrl-single,pins = <
0x44 (PIN_INPUT_PULLUP | MUX_MODE3) /* (C5) gmpc_a1.mmc2_dat0 */
0x48 (PIN_INPUT_PULLUP | MUX_MODE3) /* (C6) gpmc_a2.mmc2_dat1 */
0x4c (PIN_INPUT_PULLUP | MUX_MODE3) /* (A4) gpmc_a3.mmc2_dat2 */
0x78 (PIN_INPUT_PULLUP | MUX_MODE3) /* (A3) gpmc_be1n.mmc2_dat3 */
0x88 (PIN_INPUT_PULLUP | MUX_MODE3) /* (B12) gpmc_csn3.mmc2_cmd */ /* qspi_clk conflict */
0x8c (PIN_INPUT_PULLUP | MUX_MODE3) /* (A12) gpmc_clk.mmc2_clk */
>;
};
my_configuration _wifi_pin_sleep: my_configuration_wifi_pin_sleep {
pinctrl-single,pins = <
0x44 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (C5) gmpc_a1.mmc2_dat0 */ /* gpio1_17 */
0x48 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (C6) gpmc_a2.mmc2_dat1 */ /* gpio1_18 */
0x4c (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (A4) gpmc_a3.mmc2_dat2 */ /* gpio1_19 */
0x78 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (A3) gpmc_be1n.mmc2_dat3 */ /* gpio1_28 */
0x88 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (B12) gpmc_csn3.mmc2_cmd */ /* qspi_clk conflict */ /* gpio2_0 */
0x8c (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (A12) gpmc_clk.mmc2_clk */ /* gpio2_1 */
>;
};
However, when we insert the module we get a lot of errors:

Attached you can also find the full dmesg content.
We cross-checked the hardware and it’s fine: we connected the our WILC1000 prototype board to the Microchip ATSAMA5D44 EVK and it worked fine. Btw, the SAMA544 is running the same Kernel version of the Rico board. Given all the above, the only real difference is the SDIO driver and the device tree configuration: these are the only two things which are hw dependent.
Btw, we even lowered the SDIO speed for the TI (2Mhz), but using the SAMA544 with the same WILC1000 proto-board we could really work at almost at full speed even though the hardware was wired… so it’s not a problem of wires’ length.
Given that, we’d like to have your advices:
- Do you see any mistakes in the pin assignment of the SDIO interface?
- Atmel drivers requires to have in-bound interrupt: is the device tree well configured for this? Does it require to enable any option in the SDIO driver? Or is the cap-sdio-irq option in device tree enough?
- Since the hw set-up does not require a card detect, they suggest to add “non-removable”: I guess that the same can be done via ti,non-removable, right?
- Is the DMA properly configured? &mmc3 is the only mmc interface whose DMA’s configuration is not done on the am4372.dtsi file.
Thank you
Best Regards
Marco
