I made a mistake and wrote a wrong value in my xxx.srec file, thus to the 0x00400310 address. I tried to overwrite it but the&nbsp;PROGPPCNEXUS program throws `Error during programming` error(nothing else).</P><P>I already read that UTEST flash area cannot be deleted, but is it also non-re-writable? Is there a way to over-write this address?</P><P>Thanks to anyone who reads.&nbsp;</P><P>Best wishes.&nbsp;</P> Wed, 26 Oct 2022 12:57:18 GMT https://community.nxp.com/t5/MPC5xxx/MPC5777c-Programming-UTEST-Problem/m-p/1544063#M22240 marv_marsian 2022-10-26T12:57:18Z https://community.nxp.com/t5/MPC5xxx/MPC5777c-Programming-UTEST-Problem/m-p/1544212#M22244 <P>Hi Ekrem,</P> <P>I'm afraid there's no solution for this.
