Friendlyarm Core6818

Hi,

I try to use image NanoPi M3/T3(DietPi_NanoPiM3-ARMv8-Bullseye) for Friendlyarm Core6818 board.
This DietPi O/S works fine from SD card, but when I flash it into eMMC, it cannot boot with the following error:

I2C_WriteByte nack returned
I2C Device Address Write Abitration Error
I2C_WriteByte nack returned
I2C Device Address Write Abitration Error
I2C_WriteByte nack returned
I2C Device Address Write Abitration Error
I2C_WriteByte nack returned
I2C Device Address Write Abitration Error
Wakeup Sub CPU 1234567
CPU Wakeup done! WFI is expected.
CPU0 is Master!

Card Identify Failure
Cannot Detect SDMMC
 Image Loading Failure Try to USB boot

What should be checked for this kind of problem?

Thanks in advance,

Andry
