CC2538: Can read command from ROM bootloader be disabled?

Hi,

This post should help address your concerns:
e2e.ti.com/.../410151

Sorry for my ignorance but in post you linked it's pointed that a flash pages can be locked for writing and that debug interface can be locked.
It doesn't says anything about readout trough the serial bootloader.
Of coarse, the bootloader can be disabled but than it can be used for a in-field FW updates.

In section 8.6.2 ROM Boot Loader Backdoor Configuration in Lock Bit Page of www.ti.com/.../swru319c.pdf , you can set Enable bit to 0 which would disable Backdoor and boot loader.

But than it can't be used for updates. There is sentence in a section 8.8:

For applications that require in-field programmability, the royalty-free bootloader can act as an application loader and support in-field firmware updates.

 

Correct mi if I am wrong but there is no way to use ROM bootloader for in-field updates if security meters.
