Wrong register attributes allow modification of the device specific manufacturing data
ID: LPCBARESDK-588
Status: Fixed
First reported: 6.0.18.1182.1
Fixed in: 6.0.20.1338
Description
SmartSnippets™ Toolbox shows DA14531 OTP data with the wrong attributes (RW rather than RO) and this data is parsed from the header.txt file which is included in the SDK6.
6.0.18.1182.1\config\toolbox_resources\DA1453x\common.
This accidentally allows SmartSnippets™ Toolbox users to program these fields in OTP should not be written by the user because it could make the device non functional or operating out of specification.
Workaround
Customers working with the SDK 6.0.18.1182.1 or in earlier version, should change the header.txt file.
