no serial number and ethaddr=ff:ff:ff:ff:ff:ff #21

I currently see this output in the output from printenv:

serial#=00000000

and

ethaddr=ff:ff:ff:ff:ff:ff

Is OTP driver in u-boot expected to work?

@tekkamanninja @MichaelZhuxx could you please comment?

@atishp04 is asking me how this might be fixed.

@geertu has this been a problem for you when doing TFTP boot?

pdp7 commented 3 years ago

TFTP works ok.

I switched to the beta board instead of earlier board and it does have MAC address in OTP:

ethaddr=2c:f7:f1:1b:e3:3f

@pdp7 otp function should be ok, here is commit https://github.com/starfive-tech/u-boot/commit/3f3ac01a29ad1cd5fa519d86f81daead2447f1d4, aslo attached enviroment variables from my beta board:

efi_dtb_prefixes=/ /dtb/ /dtb/current/
ethact=dwmac.10020000
ethaddr=2c:f7:f1:1b:e3:5f
fdt_addr=fffd1b90
fdt_addr_r=0x88000000

you can try to look up your MAC address https://dnschecker.org/mac-lookup.php, the manufactury ID should be Seeed Technology Inc.
