This is the start of flash after doing a flash with your firmware:
000000 7E99AA7E 05010051 62200092 01726703 00008210 01010011 00000000 00000000
000020 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000
And this is where it ends:
0206E0 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000
020700 FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF
It should end at 0x20FB8.
