Hi !
I brought out again my A20 a few days ago for new projects after some buggy trials last year.
With a new image on the microSD card (Armbian_5.92.4_Olinuxino-a20_Debian_buster_next_5.2.21.img), the boot was complaining that the all-FF MAC address was illegal. So I used olinuxino config write to set another MAC address. However, as the MAC address is the 4th argument, I thought the first 3 were mandatory... and here is what I got :
=> olinuxino config info
Model: A20-OLinuXino-LIME2 Rev.G2
Serial:00000A48
MAC: FF:FF:FF:FF:FF:FF
=> olinuxino config write 7701 G2 00000A48 aaaaaaaaaaaa
Erasing EEPROM configuration...
Writting EEPROM configuration...
Writting MMC configuration...
=> olinuxino config info
Model: A20-OLinuXino-LIME2 Rev.G
Serial:00000A48
MAC: AA:AA:AA:AA:AA:AA
So I lost the full revision code and this command seems to be unable to write it back. I don't know where this code could be used, but I don't like it.
Is there a detailed man page for this command ?
Do you mean that instead of revision "G2" the board got set as revision "G"? If it is just that it is not a reason to worry. The changes are minor and shouldn't affect the boot or the performance.
