Olimex ESP32-POE with CMT2300A

[letmoc]

Hello, does the combination work: Olimex ESP32-POE with CMT2300A ?
If so, which device profile would be correct or how must it be adjusted.

Should work is on the whitelist from opendtu.

Hm which config do you need? Only CMT+ETH? CMT+NRF+ETH? CMT+ETH? Display? You can build it with these informations.

Maybe this is good for you?

[
    {
        "name": "Olimex ESP32-POE CMT+ETH",
        "cmt": {
            "clk": 14,
            "cs": 5,
            "fcs": ?,
            "sdio": ?,
            "gpio2": -1,
            "gpio3": -1
        },
        "eth": {
            "enabled": true,
            "phy_addr": 0,
            "power": 12,
            "mdc": 23,
            "mdio": 18,
            "type": 0,
            "clk_mode": 3
        }
    }
]

EDIT_ Pins changed - Not 100% sure

Hi there, was anyone successful with connecting Olimex ESP32-POE with CMT2300A?
I tried some combinations setting clk, cs, fcs, sdio to different GPIO pins that are exposed by ESP32-POE, but was not successful, chip status is always "not connected".

Update:
The following configuration works for me:

[
{
"name": "Olimex ESP32-POE CRMT300A",
"cmt": {
"clk": 15,
"cs": 16,
"fcs": 13,
"sdio": 2,
"gpio2": -1,
"gpio3": -1
},
"eth": {
"enabled": true,
"phy_addr": 0,
"power": 12,
"mdc": 23,
"mdio": 18,
"type": 0,
"clk_mode": 3
}
}
]

One additional obstacle when using the E49-900MBL-01 Testing Board:
I got (so it seems) a different board revision which does not match the PIN layout which is documented in the web, e.g. the PIN labeled "reset" was actually CS.
I found the correct mapping by using a circuit tester / continuity tester to check which PINs from the CMT2300A chip are connected to which PINs on the board.
I used this specification for the CMT2300A:
