Hi all,

i have an problem with the OTP Programming. I use an STM32F429 and ST-Link/V2 with the Software STM32 ST-Link Utility V3.9.0. The OTP Bytes started at 0x1FF0F000. I see the content of this Bytes (0xFF) with blue background color. I try to change one of the Bytes in 0x7F. But it doesnt't work. I become the following error message: Are there any ideas for my problem?Best regardsKai Paulus

Hi,

the OTP Programming does not work with the 

ST-Link Utility Version 3.9.  With 3.8 Version it works.
