In some cases, I failed to write empty eeprom in our PCB with BCM20737.

Commnd line tools are used in writing eeprom.

I add recover option in WICED SDK . I manage to write empty eeprom.

Can I add recover option in command line tool ?

Thanks in advance.

I've successfully solved this issue.

I have some mistake in my command option.

I share my knowledge.

I use below command to burn empty eeprom.

Chipload.exe -BLUETOOLMODE -PORT com1 -BAUDRATE 115200nfc -MINIDRIVER

uart_DISABLE_EEPROM_WP_PIN1.hex -BTP 20737_EEPROM.btp -CONFIG output.hex -CHECKCRC -ERASE -NODLMINIDRIVER -LOGTO log.txt

The below command is used in the filled eeprom.

Chipload.exe -BLUETOOLMODE -PORT com1 -BAUDRATE 115200nfc -MINIDRIVER uart_DISABLE_EEPROM_WP_PIN1.hex  -BTP 20737_EEPROM.btp -CONFIG output.hex -CHECKCRC -ERASE -LOGTO log.txt

Thank you for your concern.

Below remains the official guide to download via command line. Using the recover option is an unorthodox but clever way to circumvent the issue of why you failed to write to the eeprom occasionally. I suggest you looked into your download setup holistically.

Is this still an issue?
