Other Parts Discussed in Thread: WL1831MOD,
I have a custom board that has an AM3352 and WL1831MOD on it, wired up exactly like the EVK and MOD8 board. It does seem to be mostly working but the data wlan interface seems very unstable and eventually throws a long list of exceptions and keeps looping until the the interface is brought down.
I'm using TI's current AM335x SDK 09.01.00.001, which is kernel 6.1.46. I'm using a minimal distribution of Debian 12.1, I copied the /lib/firmware/ti-connectivity folder from the TI SDK but get the same results with either that or what's in the standard Debian distro.
My devicetree is set up exactly the same as the EVM with one exception, if I use the DMA crossbar lines the system does not see the module. If I take them out, it seems to boot up fine.
EVM:
&mmc3 {
/* these are on the crossbar and are outlined in the
xbar-event-map element */
dmas = <&edma_xbar 12 0 1
&edma_xbar 13 0 2>;
dma-names = "tx", "rx";
status = "okay";
vmmc-supply = <&wlan_en_reg>;
bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&mmc3_pins &wlan_pins>;
non-removable;
cap-power-off-card;
keep-power-in-suspend;
#address-cells = <1>;
#size-cells = <0>;
wlcore: wlcore@0 {
compatible = "ti,wl1835";
reg = <2>;
interrupt-parent = <&gpio3>;
interrupts = <17 IRQ_TYPE_EDGE_RISING>;
};
};
Mine:
&mmc1 {
/*dmas = <&edma_xbar 12 0 1
&edma_xbar 13 0 2>;
dma-names = "tx", "rx";*/
//max-frequency = <1000000>;
vmmc-supply = <&wlan_en_reg>;
bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&mmc1_pins &wlan_pins>;
ti,non-removable;

wlcore: wlcore@0 {

};
};
