---hR55VyWSs4XhNyqY0lAKFkYy0Tf6BAbk6AZSzx Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hi Prashant, As Richard indicated the debuggers set up many registers when they start ru= nning. One more guess is that controller is unable to access the flash on power on= reset. It requires RCW register in shadow flash to be configured. I don't remember how I programmed shadow flash about 2 years back, but one = way is to write through an application running out of RAM.
