I have some questions about using FLASH_DOWNLOAD_TOOL in production.Start conditions:
1. We have a pre-signed and pre-encrypted binary for the bootloader, partition table, and factory app.
2. We are using 192-bit keys for flash encryption and secure boot.
3. We need to burn to eFuse some additional parameters, that are not listed at security.conf file and this part of manual
- burn_efuse FLASH_CRYPT_CONFIG 0xF
- burn_efuse CODING_SCHEME 1
- burn_efuse FLASH_CRYPT_CNT
- write_protect_efuse FLASH_CRYPT_CNT
- burn_efuse CONSOLE_DEBUG_DISABLE
- burn_efuse ABS_DONE_0
4. Also, we need to log all console out from espefuse.py and esptool.py to separate files for every controller (_MAC_ADDRESS_-flash.log and _MAC_ADDRESS_-efuse.log for example).
Now we are using this bash script to flash FW end burn eFuse. There is no handling for esptool and espefuse exit codes yet, and its work fine, but only for single programmer setup.
