When I look at your output, I notice

    Debug: 1939 19560 target.c:2030 target_write_buffer(): writing
buffer of 1156 byte at 0x00000000
and
    Error: 1957 19654 arm_adi_v5.c:378 mem_ap_write(): Failed to write
memory at 0x00000004

This suggests you're linking your code at 0x00000000 in stead of
0x08000000, the address, where the flash exists.
Even through the 0x00000000 is aliased to 0x08000000, you might try
linking your code at 0x08000000 in stead of 0x00000000
