![]() ![]() This won’t happen every day, but rarely you may come across an old website that asks you to install Flash on your Mac. Adobe recommends that you uninstall it now! The configuration seems some traps to makes the flashing unsafe now.UPDATE: Adobe Flash Player has finally seen the end of its life. Hope there is a flowchart to explain how these configurations affect the procedure. ![]() If debug is set to false, will these confusing settings take effects? I guess some of them are designed for debugging, but there is already a debug setting. But I don't know why should set this to true. If the keys can be read, what's the point?Īnd secure_boot_force_write and flash_encrypt_force_write, I get it now eFuse can't be set from 0 to 1, so if there is already a key burned, burn again with force could set the key wrong. ![]() I don't know the point to set secure_boot_rw_protect and flash_encrypt_rw_protect to false. If the keys are not burned, is the procedure skip the digest generation and pre-encryption part? If not skip, the bootloader and app can't run without the keys in the eFuse. I don't know the point to set burn_secure_boot_key and burn_flash_encryption_key to false. It's faster and more reliable than doing all the job by bootloader on first boot.īut the configurations are really confusing. ![]() Cause each boards' keys are different, the codes are safe. Then flashed all these to the ESP32 chip, at last burn the keys into eFuse and burn some other marking and disabling eFuse. The downloader generated the secure boot and flash encryption key by PC and calculate the bootloader's digest, then encrypts the digest, bootloader, partitions table, and app binary file. I guess the Downloader's procedure is similar to Reflashable Secure boot and Pre-generated Flash Encryption Key. The best way to figure out the eFuse setting result is run espefuse.py summary after using the FlashDownloadTool to check the eFuse's states.Īny news of the fixed FlashDownloadTools? Hi, the flash encryption key is read/write protected, but if the FLASH_CRYPT_CNT is not write protected and secure boot is not enabled, flash encryption will be ineffective. ![]()
