Change the partition table offset to 0x9000 from 0x8000 since after enabling flash encryption the size of bootloader is increased. +Note: After enabling flash encryption, the bootloader size increases, which means that the offset of the partition table must be changed to 0x9000 from 0x8000 to prevent the bootloader from overlapping with the partition table. In this example, the default offset of the partition table is 0x9000. ### Build and Flash diff --git a/examples/security/flash_encryption/partitions_example.csv b/examples/security/flash_encryption/partitions_example.csv index a7df975994..d352ff92aa 100644 --- a/examples/security/flash_encryption/partitions_example.csv +++ b/examples/security/flash_encryption/partitions_example.csv @@ -1,5 +1,5 @@ # Name, Type, SubType, Offset, Size, Flags -nvs, data, nvs, 0x9000, 0x6000, +nvs, data, nvs, , 0x6000, # Extra partition to demonstrate reading/writing of encrypted flash -storage, data, 0xff, 0xf000, 0x1000, encrypted -factory, app, factory, 0x10000, 1M, +storage, data, 0xff, , 0x1000, encrypted +factory, app, factory, , 1M, diff --git a/examples/security/flash_encryption/sdkconfig.defaults b/examples/security/flash_encryption/sdkconfig.defaults index 6a8feba65b..3300ebfb1a 100644 --- a/examples/security/flash_encryption/sdkconfig.defaults +++ b/examples/security/flash_encryption/sdkconfig.defaults @@ -2,3 +2,4 @@ CONFIG_PARTITION_TABLE_CUSTOM=y CONFIG_PARTITION_TABLE_CUSTOM_FILENAME="partitions_example.csv" CONFIG_PARTITION_TABLE_FILENAME="partitions_example.csv" +CONFIG_PARTITION_TABLE_OFFSET=0x9000
