Once you are familiar with the process of flashing the firmware using the sdkconfig templates that are included in the /config folder of this repository, there are some additional changes that you should make to these files before using the device with actual funds.
There is also a helper script tools/mkdefaults.py to assist, which reads a given sdkconfig defaults file, makes appropriate changes, and writes the results as the top-level sdkconfig.defaults file.
(NOTE: this script should be passed a base file and one or more directives - it reads the changes it is going to make for each directive from the mkdefaults.dat.json file.)
If editing the default development configuration template...
Add
CONFIG_LOG_DEFAULT_LEVEL_NONE=y
Remove
CONFIG_DEBUG_MODE=y
This can be accompished with, for example:
./tools/mkdefaults.py ./configs/sdkconfig_display.defaults NDEBUG
If you want to maximise the physical security of your device and prevent it from running firmware that you haven't signed with your signing key, you can also enable Secure Boot. If applied together with removing the debug features, this is designed to mimic the settings found on a retail Jade device.
Warning: Doing this cannot be un-done, nor can the signing key that the device will accept be changed.
Read the official vendor documentation
Add
CONFIG_ESP32_DISABLE_BASIC_ROM_CONSOLE=y
CONFIG_SECURE_DISABLE_ROM_DL_MODE=y
CONFIG_SECURE_BOOT_SIGNING_KEY=<PATH_TO_YOUR_SIGNING_KEY>
CONFIG_SECURE_BOOT=y
CONFIG_SECURE_FLASH_ENC_ENABLED=y
CONFIG_SECURE_FLASH_ENCRYPTION_MODE_RELEASE=y
CONFIG_ESP32_REV_MIN_3=y
Depending on the hardare you have selected, you may need to remove the last line that requires a minimum of Rev3 hardware...
Remove
CONFIG_EFUSE_VIRTUAL=y
CONFIG_ESP32_REV_MIN_1=y
This can be accompished with, for example:
./tools/mkdefaults.py ./configs/sdkconfig_display.defaults NDEBUG SECURE
If you would prefer to completely disable Bluetooth, you can also make the following modifications to your configuration template.
Add
CONFIG_APP_NO_BLOBS=y
CONFIG_MBEDTLS_ECP_RESTARTABLE=y
CONFIG_MBEDTLS_CMAC_C=y
Remove
CONFIG_BT_ENABLED=y
CONFIG_BT_NIMBLE_ENABLED=y
CONFIG_BT_NIMBLE_MEM_ALLOC_MODE_EXTERNAL=y
CONFIG_BT_NIMBLE_MAX_CONNECTIONS=1
# CONFIG_BT_NIMBLE_ROLE_CENTRAL is not set
# CONFIG_BT_NIMBLE_ROLE_BROADCASTER is not set
# CONFIG_BT_NIMBLE_ROLE_OBSERVER is not set
CONFIG_BT_NIMBLE_NVS_PERSIST=y
# CONFIG_BT_NIMBLE_SM_LEGACY is not set
CONFIG_BT_NIMBLE_SVC_GAP_DEVICE_NAME="j"
CONFIG_BT_NIMBLE_GAP_DEVICE_NAME_MAX_LEN=11
CONFIG_BT_NIMBLE_ATT_PREFERRED_MTU=517
CONFIG_BTDM_CTRL_BLE_MAX_CONN=1
# CONFIG_BTDM_CTRL_FULL_SCAN_SUPPORTED is not set
# CONFIG_ESP32_WIFI_SW_COEXIST_ENABLE is not set
This can be accompished with, for example:
./tools/mkdefaults.py ./configs/sdkconfig_display.defaults NORADIO
If you have enabled secure boot with the settings suggested above you will need to do firmware updates via OTA.
An example command to do this using the jade.bin file in the /build folder would be:
python jade_ota.py --noagent
