ULINK Pro and STM32 read-out protection

G .

Hi,

My application has enabled read-out protection level 1 on an STM32F4 MCU.  My understanding is that this is reversible, causing a mass erase.  However, how can I disable/reverse read-out protection using uVision and ULINK Pro, given that I can no longer erase/program the flash via JTAG.  I have searched the internet and it seems it is only possible to reverse it using an ST-Link programmer.  Is this really the case?  Is it possible to do this with uVision  and ULINK?

Thanks
