Jatson Nano boot fail after modified MAC address in E2PROM


We need a new MAC address in E2PROM on Jetson Nano, but it can’t boot after modified it, the display and keyboard is not respond, thanks.

sudo i2cset -f -y 2 0x50 0x49 0x5c
sudo i2cset -f -y 2 0x50 0x48 0x86
sudo i2cset -f -y 2 0x50 0x47 0x13
sudo i2cset -f -y 2 0x50 0xb1 0x5c
sudo i2cset -f -y 2 0x50 0xb0 0x86
sudo i2cset -f -y 2 0x50 0xaf 0x13

Did you remember to modify the checksum in the last field of eeprom?

Thank you very much for your reply, which checksum algorithm is used in this EEPROM, how to calculate it, and where should I fill in the checksum field?thank you so much!

We put the method in eerpom layout of TX1/TX2 document. Please check it in our download center.

Because the value of E2PROM has been modified, the system has been unable to start, what should I do now to restore it?


What error did you hit when boot up? Could you share the UART log?
