ADIN2111 not works

[lmikl]

hello,

The driver for the ADIN2111 which was recently integrated into zephyr 3.4.0 does not work.

I am currently using my own driver and the component works well.

If I try to use the driver integrated in zephyr I just have the message (uart:~$) which appears on the console.
In debug mode under eclipse I think that the cpu does not start. it is idle.

if someone can solve the problem.

other information:
i used a GD32F427
my dts :

&spi1 {
pinctrl-0 = <&spi1_default>;
pinctrl-names = "default";
interrupts = < 0x24 0x0 >;
cs-gpios = <&gpiob 12 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
status = "okay";
my_adin: adin2111@0{
compatible = "adi,adin2111";
reg = <0x0>;
spi-max-frequency = <10000000>;
int-gpios = <&gpioe 14 GPIO_ACTIVE_LOW>;
reset-gpios = <&gpioe 15 GPIO_ACTIVE_LOW>;
port1 {
local-mac-address = [ 00 E0 22 FE DA C8 ];
};
port2 {
local-mac-address = [ 00 E0 22 FE DA C8 ];
};
mdio: mdio {
compatible = "adi,adin2111-mdio";
status = "okay";
#address-cells = <1>;
#size-cells = <0>;
phy@1 {
reg = <0x1>;
compatible = "adi,adin2111-phy";
status = "okay";
};
phy@2 {
reg = <0x2>;
compatible = "adi,adin2111-phy";
status = "okay";
};
};
};
};

my prj.conf :

CONFIG_SPI=y
CONFIG_ETH_ADIN2111=y
CONFIG_ETH_ADIN2111_SPI_CFG0=n

I am not the owner of the driver but I have been working with the ADIN1110 . Can you set a breakpoint on the init function of the driver and see what is happening

zephyr/drivers/ethernet/eth_adin2111.c

Line 768 in d7504ab

static int adin2111_init(const struct device *dev)

[vChavezB]

I checked the generated dts and conf header files in the build folder and seem correct. Not sure why the driver does not initialize. I would activate zephyr log in your proj.conf and enable debug messages for the ethernet driver to enable the log module of the adin driver

zephyr/drivers/ethernet/eth_adin2111.c

Line 8 in d7504ab

LOG_MODULE_REGISTER(eth_adin2111, CONFIG_ETHERNET_LOG_LEVEL);

[lmikl]

I have already activated the logs but nothing appears on the console

[vChavezB]

Not even the Zephyr Boot string?

[lmikl]

No. only uart:~$

[vChavezB]

I dont have a board at the moment to test this, but I pressume the driver is somehow not starting as expected. The only thing I can recommend is verifying what drivers are loaded i.e. set a breakpoint where the kernel starts and try to figure out what is happenning

https://github.com/zephyrproject-rtos/zephyr/blob/0aaedf72058b8d492eb491c703de37256ff15247/kernel/init.c#L525C20-L525C28

@lmikl hello, you might have to modify the priorities and enable extra sub-systems required by it:

# Net
CONFIG_NETWORKING=y
CONFIG_NET_L2_ETHERNET=y
## ADIN
CONFIG_ETH_ADIN2111=y
CONFIG_MDIO=y
CONFIG_MDIO_ADIN2111=y
CONFIG_PHY_GENERIC_MII=n
CONFIG_PHY_ADIN2111=y

CONFIG_ETH_ADIN2111_INIT_PRIORITY=71
CONFIG_MDIO_INIT_PRIORITY=72
CONFIG_PHY_INIT_PRIORITY=73
# default
CONFIG_ETH_INIT_PRIORITY=80

Priorities play the major role here. Same goes for SPI init priority, should be higher (numerically lower) than ADIN.

ping doesn't work form the host.
there is a checksum error.

[lmikl]

after a quick debug, I think 4 bytes are missing from each frame send by the driver

[lmikl]

i think, i found the error. When the size is transmit by the function eth_adin2111_reg_write the wrong value is transmit. padded_size is transmit instead of burst_size.

but i need to add also 1 to have the end of frame but i don't know why.

ret = eth_adin2111_reg_write(adin, ADIN2111_TX_FSIZE, burst_size+1);

[GeorgeCGV]

ADIN2111_TX_FSIZE is the frame size, not the spi transfer size. Therefore, burst size is not written there.

[lmikl]

yes you are right.

But it missing 4 bytes on each frame send by the adin.
