Ok, I got it, I has missed the in my overlay file

zephyr,concat-buf-size = <520>;

Sorry, just realised my overlay file had some old code in it.

I have updated it to this..

/ {
        chosen {
		zephyr,display = &ssd1306;
        };
};

&pinctrl {
	uart0_default_alt: uart0_default_alt {
		group0 {
			psels = <NRF_PSEL(UART_TX, 0, 24)>, <NRF_PSEL(UART_RX, 0, 22)>;
		};
	};

	uart0_sleep_alt: uart0_sleep_alt {
		group1 {
			psels = <NRF_PSEL(UART_TX, 0, 24)>, <NRF_PSEL(UART_RX, 0, 22)>;
			low-power-enable;
		};
	};

	i2c1_default_alt: i2c1_default_alt {
       		group2 {
          		psels = <NRF_PSEL(TWIM_SDA, 0, 17)>,
                  		<NRF_PSEL(TWIM_SCL, 0, 20)>;
       			};
    		};
};

&uart0 {
	pinctrl-0 = <&uart0_default_alt>;
	pinctrl-1 = <&uart0_sleep_alt>;	
	pinctrl-names = "default", "sleep";

	compatible = "nordic,nrf-uart";
	current-speed = <115200>;
	status = "okay";
};

&i2c1 {
    status = "okay";
    compatible = "nordic,nrf-twim";
    pinctrl-0 = <&i2c1_default_alt>;
    pinctrl-names = "default", "sleep";
    clock-frequency = <I2C_BITRATE_STANDARD>;  

	ssd1306: ssd1306@3c {
      	compatible = "solomon,ssd1306fb";
        	reg = <0x3c>;
        	label = "SSD1306";
        	height = <32>;
        	width  = <128>;
        	segment-offset  = <0>;
        	page-offset     = <0>;
        	display-offset  = <0>;
        	multiplex-ratio = <31>;
        	prechargep      = <0xD1>;
        	segment-remap;
        	com-invdir;
        	com-sequential;
    	};

};


&i2c1 {
/delete-property/sda-gpios;
/delete-property/scl-gpios;
};

&adc {
	status = "ok";
};

This allows the code to build, but am now seeing thus error

<err> i2c_nrfx_twim: Need to use concatenation buffer and provided size is insufficient (1 + 512 > 16). Adjust the zephyr,concat-buf-size property in the "I2C_1" node.
