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.
