hello
can you help me of below error that occured.

system_api: Base MAC address from BLK0 of EFUSE CRC error, efuse_crc = 0x; calc_crc = 0x.

The ESP32 can store the CRC of the Base MAC address in eFuse. The error you posted means that there is a mismatch between the SW calculated CRC and the CRC stored in eFuse. This could be due to a bad MAC address, or that the eFuse CRC is bad, or both.

I have the same issue. The reason is explained well, but how can I fix this problem?
