Details:

The addressing config for flash programming is off ( loadpage_lo / loadpage_hi
/ writepage). 

According to the datasheet it is 512 32-word pages, 
so it needs to be a3-0 for loadpage and a12-a4 for writepage.

The sympton is verification failures and on reading back the flash blocks of
32 words corrupted data followed by 3 x 32 words of 0xff.

After changing it to:
        loadpage_lo     = " 0 1 0 0 0 0 0 0", 
                          " 0 0 0 x x x x x", 
                          " x x x x a3 a2 a1 a0", 
                          " i i i i i i i i"; 
        
        loadpage_hi     = " 0 1 0 0 1 0 0 0", 
                          " 0 0 0 x x x x x", 
                          " x x x x a3 a2 a1 a0", 
                          " i i i i i i i i"; 
        
        writepage       = " 0 1 0 0 1 1 0 0", 
                          " 0 0 0 a12 a11 a10 a9 a8", 
                          " a7 a6 a5 a4 x x x x", 
                          " x x x x x x x x"; 
it now works fine for me.
