Hi
I've successfully changed the ICSSG0-pru firmware from *-prueth-fw.elf to *-prusw-fw.elf using the devlink to activate theswitch-mode.
However, I’d now like to make this change permanent via .dts file. To do so, I tried updating the .dts file to reference the new firmware files, but it didn’t work.
Below are the relevant lines from my .dts file:
icssg0_eth: icssg0-eth {
compatible = "ti,am642-icssg-prueth";
pinctrl-names = "default";
pinctrl-0 = <&icssg0_rgmii1_pins_default &icssg0_rgmii2_pins_default>;
sram = <&oc_sram>;
ti,prus = <&pru0_0>, <&rtu0_0>, <&tx_pru0_0>, <&pru0_1>, <&rtu0_1>, <&tx_pru0_1>;
firmware-name = "ti-pruss/am65x-sr2-pru0-prusw-fw.elf",
"ti-pruss/am65x-sr2-rtu0-prusw-fw.elf",
"ti-pruss/am65x-sr2-txpru0-prusw-fw.elf",
"ti-pruss/am65x-sr2-pru1-prusw-fw.elf",
"ti-pruss/am65x-sr2-rtu1-prusw-fw.elf",
"ti-pruss/am65x-sr2-txpru1-prusw-fw.elf";
ti,pruss-gp-mux-sel = <2>, /* MII mode */

iep = <&icssg0_iep0>, <&icssg0_iep1>;
interrupt-parent = <&icssg0_intc>;
interrupts = <24 0 2>, <25 1 3>;
interrupt-names = "tx_ts0", "tx_ts1";
dmas = <&main_pktdma 0xc100 0>, /* egress slice 0 */

"tx1-0", "tx1-1", "tx1-2", "tx1-3",
"rx0", "rx1";
ethernet-ports {
#address-cells = <1>;
#size-cells = <0>;
icssg0_emac0: port@0 {
reg = <0>;
phy-handle = <&icssg0_phy1>;
phy-mode = "rgmii-id";
syscon-rgmii-delay = <&main_conf 0x4100>;
/* Filled in by bootloader */
local-mac-address = [00 00 00 00 00 00];
};
icssg0_emac1: port@1 {
reg = <1>;
phy-handle = <&icssg0_phy2>;
phy-mode = "rgmii-id";
syscon-rgmii-delay = <&main_conf 0x4104>;
/* Filled in by bootloader */
local-mac-address = [00 00 00 00 00 00];
};
};
};I suspect I may also need to explicitly enable the switch-mode in the device tree, but after reviewing other .dts files, I haven’t been able to find the correct way to do this.
Is there a standard method to configure and load the *-prusw-fw.elf firmware for ICSSG0-PRU directly through the device tree?
Thanks in advance for your help!
Best regards,
