LAUNCHXL-CC26X2R1: How to use SBL to flash application without erasing secondary BLE address?

Part Number: LAUNCHXL-CC26X2R1
Other Parts Discussed in Thread: UNIFLASH


I am using "simplelink_cc13x2_26x2_sdk_4_40_00_44" to develop my application. We have to use our own BD address in BLE application which been written in secondary BLE address by uniflash by j-tag. Because after product assembly, there is no j-tag but only UART we can use. So I find SBL solution in "ti154stack_linux_x64_4_30_00_06" which also support cc26x2 but once using SBL to flash new image, the secondary BLE address would be erased. Is it possible to flash image without erasing my BLE address?
